 Common Problems

Just like other machines and appliances, you may also experience problems with your fridge and freezer. For example, what happens when you fridge won’t cool. This can be a problem especially if you want to stock your items in your fridge. Apart from that, this would also mean additional costs since it will take too long for any item to cool.

There are other common problems that you may also experience:

1. Does not run, no light in refrigerator

No power – AC outlet defective or open circuit

Service cord defective – Transfer to electrician

2. Does not run, light in refrigerator works

With the introduction of ‘V’-series, top of the range cabinets will be fitted with a Westinghouse Virtuoso

Electronic control. This consists of a Control Board, Display Panel and Two Sensors. Functionally this

replaces the thermostat and defrost timer and provides some extra features.

Page 8  RESI115





The electronic control consists of the following parts-

Control board located in the machine compartment.

Display Panel recessed into the top centre of the food compartment door.

Two sensors, (wired into the cabinet harness) one in the fresh food compartment and one in the

freezer compartment.


The Control Board houses the transformer, 3 relays (compressor, fan and defrost heater) and input

circuitry to monitor when the door/defrost heater is open/on and for how long. A processor controls the

timing on some of the functions such as the door alarm and also communication between the Control

Board and Display Panel.


The Display Panel consists of a LCD Display with blue backlighting and seven push buttons. A

processor controls the LCD segments and also communication between the Display Panel and Control



The sensors are negative temperature coefficient silicon devices encapsulated in a PVC tube sealed with

epoxy resin. Typical resistance at 25°C is 5000 ohms, at 0°C is 16325 ohms and at -25°C is 65200 ohms.





The system operates under software control from direct current inputs from sensors located in the freezer

and fresh food compartments.


The fresh food compartment is supplied with cold air from the freezer compartment by a fan located in

the freezer compartment. The flow of air to the fresh food compartment is controlled by a motorised

baffle that is either fully open or fully closed. This baffle takes 12 seconds to open or close.The baffle is

located in the rear control housing at the air outlet of the freezer.


When the freezer compartment is too warm, the compressor is turned on (by the freezer sensor signal)

together with the fan. The fan draws refrigerated air (dry, sub-zero air) from a finned evaporator coil.


When the fresh food compartment is too warm, the baffle in the rear control housing is opened.

Depending on which cycle the refrigerator is in (On or Off) depends on which of the following will

occur :-

• If the freezer fan and compressor are on, the cold air will flow from the freezer into the food


• If the freezer fan and compressor are off, the temperature of the food compartment must rise another

2ºC before the freezer fan motor is activated. The compressor will not switch on until the freezer

sensor reaches its set point.

For each half hour of a 24 hour period, the amount of time the door is open for the half hour is recorded.

This is compared with three previous values and the three maximums out of the four values are kept.

This procedure is repeated for the 24 hour period until the three daily maximums have been recorded

(Basically trying to match breakfast, lunch and tea).


The next day each half hour maxima is preceded by an extra cooling period that tries to reduce the

freezer compartment air temperature to 3°C below the set point. A 30 minute time limit applies. This

provides extra capacity for the expected door opening period.


The same three maximums are also used to try and prevent defrosts from occurring during those times of

maximum door opening, provided a minimum run time is met. After each defrost the compressor run

time for the next period is set to one of seven values between 6 and 16.5 hours based on

the heater on time of that defrost. If during the next period there are door openings the run time is

reduced in six stages to compensate for the extra moisture load.






When the cabinet is first switched on (or after a power failure) all counters are reset to zero on the

Control Board and then initial conditions are set. (The Display Panel holds its memory for 90 seconds so

that if the power interuption is less than 90 seconds the Display Panel memory will be re communicated

back to the Control Board. This memory only covers functions such as Quick Freeze, Temperatures,

Clock Time, Holiday Mode & Drinks Chill. The main functions memory on the Control Board will be

lost.) The compressor should then run continuously until the set air temperature of the freezer

compartment sensor is reached and the baffle will remain open until the set air temperature of the fresh

food compartment sensor is reached. The compartments will then cycle about the set air temperatures.

When 1 hour 40 minutes has elapsed a defrost will occur (required because the electronics retains no

memory during a power failure, this stops the possibility of extended run time between defrosts causing

excessive ice build-up), the compressor run time to the next defrost is now set and the cabinet is now in

its normal operational state.


Defrost Timing: On the Electronic models defrost timing is 6 to 22 hours of compressor run time,

followed by 10 minutes of fan run only. During this 10 minute period the damper is open to drop cold air

from the freezer into the food compartment. This warms up the temperature of the evaporator and

decreases the length of defrost time.This is followed by the lesser of a 35 minute defrost period or heater

on time plus 4 minutes drip time. The heater on time is determined by the defrost termination thermostat

(DTT). The defrost heater on time is sensed through the defrost heater and the DTT. The fan is delayed

from starting for 5 minutes after defrosting (after drip time), to allow the refrigeration system to pull

down to temperature, but must start when cabinet is first turned on.


System Equalisation

: The compressor off cycle will never be less than 6 minutes duration even if the

freezer sensor is warmed up manually or the wiring short circuited. This allows the system pressures to

equalise so the compressor starts under no load.


Failure Mode

: The compressor and fan motor relays are wired in their normally closed positions, this

means that if 240V AC is supplied to the power board but the control board is not functioning then the

compressor and fan will run continuously. This allows the customer time to call for service.


The 24 hour period for the 3 daily door opening maximums starts from when the cabinet is first switched

on. The door openings are sensed through the fresh food compartment door only via the light switch. If

the light bulb fails door openings are still sensed. If the light switch fails on the electronics will default

to 6 hours of run time between defrosts. If the light switch fails off the time between defrosts will be set

by heater on time only and may cause defrost problems if there are large numbers of door openings.

minutes after defrosting (after drip time), to allow the refrigeration system to pull down to temperature,

but must start when cabinet is first turned on.


If the Heater Relay on the Control Board or the D.T.T. fails the circuitry relies on the Thermal Fuse to

safeguard the refrigerator, therefore it is ESSENTIAL that the Thermal Fuse is always replaced if it




The DTT can be open circuit for two reasons:-

It is faulty.

It is warm (The refrigerator has been switched off or just completed a defrost)

To overcome this, the DTT can be shorted out by carrying out the following. Switch off the

power, remove the service cord. Place an insulated wire loop in the LH socket of the control

box (See diagram). Replace the service cord and switch on the power, run the diagnostics.  

Do not forget to remove the wire loop when you have completed the diagnostics.





This will usually appear if the “run test” loopback connector has been left in place during factory

testing. This connector can be found connected to the control board in the machine compartment,

see diagram below.

With the connector in place, on switch on at the customers’ house the refrigerator will run through

a preset sequence over a period of 45 minutes. Most of the time, the display will read “SEn” with

the actual food and freezer temperatures displayed also. At the end of the 45 minutes, the

refrigerator will revert to normal operation. So, if there is a service call where the customer says

the display says “SEn”, and the buttons do not change the display.


Advise the customer that they can either:


Switch off the refrigerator and remove the loopback cable (See diagram above) by pulling on the

white and orange twisted wires, (There is no clip on the connector). Switch the refrigerator on.




Tell them that the refrigerator will go to normal operation after 45 minutes.


It should be noted that with the connector fitted, every time the refrigerators’ power is switched off

and on, the above sequence will be repeated.  


This also means the refrigerator will not go into Diagnostics with the connector fitted.

To remove the handle cover, grip the rear of the cover near the gasket. Pull the cover towards

the front of the door in an arc.

To fit the cover, locate the clips on the cover into the recesses in the front of the door handle.

Page 25  RESI115

Hinge the cover towards the gasket and snap over the handle.


To remove the door gasket, start in one of the corners and pull perpendicular to the inner door

panel. Once it is released from the corner it can then be peeled off the remainder of the door.



To fit a gasket, start by pressing it into the corners first.

With the gasket fitted into the corners, move around the door pressing the gasket into the

inner panel groove using your thumbs.





Before performing the following, ensure that power is removed from the cabinet by switching off

the mains supply and disconnecting the service cord from the power outlet. Move the cabinet to a

position, which will allow easy access to the machine compartment and food compartment door.

Discharge any static electricity that you may be carrying by touching any exposed metal part of the

cabinet. (Note that even though the service plug is removed it is important to touch the cabinet

before continuing). The facia on the food compartment door display, (the facia carries the

Westinghouse logo and the word virtuoso)   needs to be removed. This can be done, by using a firm

but non-abrasive object, so not to damage the door surface (a plastic ice-scraper works well). Push

vertically up on the under-side of the facia.

With pressure applied, the Facia will bow disengaging its bottom clips from the Electronic Board.

Page 28  RESI115

Remove the bevelled edge off an ice

scraper to produce a tool for removing

the Facia Display

Hinge the Facia upwards to remove.

Once the facia is removed, you should see the two screws which hold the display in

place. Remove and retain these two screws

Page 29  RESI115

Pull the Electronic Board out from the bottom, then down from the top to remove from the

cover locating clips.

Disconnect the cable from the display board. From the front view, the cable should enter

the foam pocket from the right and be long enough to pass across to the left hand side of

the pocket. The new display will have its connector on the right hand side (the old board

had it on the left), so there will be excessive cable which needs to be bundled as tightly

as possible (coiled) such that it does not travel across the back of the display once

installed. The important thing here is that the cable must be situated such that the new

board will fit back into the pocket. Connect the cable to the new board and fit the board

back into the pocket in the food compartment door. Replace the screws that were

removed previously. Replace the facia by fitting the tabs at the top of the facia first, then

push below and above the display buttons. Note that once the facia is fitted it may be

necessary to ensure that the buttons are not being depressed by the facia. To do this, run

your finger along each button to ensure that they sit just above the surface of the facia.




Before performing the following, ensure that the power is removed from the cabinet by switching

off the mains supply and disconnecting the service cord from the power outlet. Move the cabinet to

a position, which will allow easy access to the machine compartment. Discharge any static

electricity that you may be carrying by touching any exposed metal part of the cabinet. (Note that

even though the service plug is removed it is important to touch the cabinet before continuing).

From the rear of the cabinet, the control electronics is located at the bottom, in the machine

compartment on the left hand side. Remove and retain the two screws which secure the electronics

box to the cabinet. There is a metal tab in the side of the box which fits into the side of the wall

and there may be an adhesive strip along the side of the box. If the adhesive strip is present, it will

take some effort to remove the box. Once the box is removed, disconnect the five connectors from

the box. Four of the connectors pull off once their latch is depressed. (The main power connector

has an under-latch, as does the flying lead from this connector to a two-pin connector directly to

the box. The two long connectors have over-latches) The remaining three pin connector which

attaches to a hole in the box itself can be removed by pinching the clips on the outside of the box

at each side of the connector and pushing it INTO the box. Note that a significant inclusion to the

new control box is an earth wire, connected to the box itself. Be sure that this earth lead is not

tangled or hidden during installation. Once all the cables are disconnected, take the new control

box and connect each of the cables. Install the 3 pin connector into the metal box first, followed by

the other long connectors. Then connect the square power connector and finally the two pin

connector on the flying lead. You MAY remove the cover on the adhesive strip that runs along the

side of the new box, though the adhesive strip is no longer necessary since a hook has been

included in the metal tab. While positioning the new controller, be sure that the three coloured

cables are routed out of the top of the box, and the two grey cables are routed out the bottom of the

box. Slide the metal tab into the slot on the wall of the compartment and position the two holes in

the box over the existing screw holes in the back of the compartment. Reuse the two screws to

secure the metal box. The final step in the installation is to fasten the earth lead to the baseplate.

You will notice that there are already earth leads connected to the baseplate at a raised tab. DO

NOT REMOVE ANY OF THESE CONNECTIONS. There is an additional hole in the baseplate

to the left of the raised earth tab on the flat part of the baseplate. Using an appropriate screw and

star washer, connect the lug on the end of the earth lead to the baseplate at this additional hole.

Installation is now complete and the system can be tested. Reconnect the cabinet service cord to

the power-point and switch it on.

To remove the evaporator cover, use a hooked tool similar to the one in the drawing below

Two plug buttons covering the screws can be removed with a flat bladed screwdriver

Carefully warming up the evaporator cover with a hair dryer will make it pliable for removal.

Place the hooked tool pointing downwards into the bottom corners of the louvres (as indicated

by the arrows). Pull on the tool until the clips on the rear of the cover disengage to the extent

that the cover is removable by hand.


To refit, position the evaporator cover into the rear of the freezer and push firmly to lock the

clips into place.

Recommended minimum clearances are :

• 3cm on each side.

• 9cm above the refrigerator.

• 5cm below the refrigerator.

Page 38  RESI115

The refrigerator should arrive with the front adjustable rollers wound down to tilt the top of the

refrigerator backwards by about 10-15mm from the upright. The stability foot should also be

wound fully up so it will not interfere with the operation of the rollers.


WARNING: The rollers are designed for forward and backward movement only. They are

not castors. Moving the refrigerator sideways may cause damage to the floor and rollers.

• Roll the refrigerator into its final position.

• The top of the refrigerator should be tilted back by approximately 10-15mm. This will allow

the doors to self-close providing a consistent door seal. It is normal for the freezer door to

momentarily open and reclose when the food compartment door is closed firmly. If the freezer

door stays open you will need to tilt the refrigerator backwards a little further.

• If the refrigerator is not tilted back, you can adjust the two front rollers by turning the large

plastic roller nut. This will increase the height of the rollers. One turn of the nut will tilt the

refrigerator back approximately 10mm. If you have difficulty turning the roller nut you can

have someone tilt the refrigerator back, so that you have better access. Alternatively, you can

access the rollers from the side, using a flat screwdriver to help you turn the nut.

Page 39  RESI115

• Check the alignment of the refrigerator to the surrounding cupboards. The top of the

refrigerator should be level from side to side. If you need to adjust the level, use the adjustable


• If the refrigerator now rocks from one corner to the opposite rear corner, this means that the

floor is uneven, you will need to put some packing under one of the rear rollers. You could use

thin pieces of solid material, such as thin board, vinyl floor tiles or laminate. Place the packing

so that it will sit under one of the rear rollers when the refrigerator is rolled into position.

Page 40  RESI115

When you have the refrigerator in its final position wind the stabilising foot down until it just makes

contact with the floor. When you need to move the refrigerator, be sure to wind the foot back up

so that the refrigerator can roll freely.  

Stabilising foot wound down.



To keep your stainless refrigerator looking at its best, you should clean it regularly. You clean

the stainless steel doors with luke-warm soapy water and a soft cloth, rinsing with clean water

and then wiping with a lint- free cloth.


To give your stainless refrigerator a renewed look, apply a light coat of white oil (e.g. Castrol

White Oil) with a lint free cloth. It is important to wipe in the direction of the grain of the

stainless steel to avoid undue marking of the surface.







You should only use the stainless steel cleaners where the stainless steel is extremely dirty or

discoloured. The manufacturers instructions for the stainless steel cleaners should always be

followed. If you use stainless steel cleaners or white oil, keep them out of contact with

moulded plastic components, handles, nameplates, door gaskets and the interior of the

refrigerator. The cleaners may damage these components. The refrigerator warranty will not

cover damage caused by these cleaners.
