Question about Zanussi Freezers

Open Question

Zanussi Fridge Freezer ZNB323W. Freezer was working but Fridge was not cooling. Compressor running non stop.Switched it off 36 hrs ago to defrost ice built up inside the top compartment of freezer. Switched it on and could feel and hear fan running in freezer but after 5 minutes the compressor clicked and stopped. Is this model on a timer to reset itself after a number of hours switched off or something is not working properly? Could you please let me know? Thank you.

SOURCE: Compressor Stopping

compressor is running overloaded possible problems bad relay/overload /capacitor dirty or clogged condensers if the unit uses a condenser fan suspect a bad fan. and defective thermostats are notorious for short cycling. id check the coils first and if dirty clean up maybe that can be the major problem.

You have a defrost problem. It means you have 3 parts that can be involve ( timer, defrost thermostat, element) most of the time it's the timer. Hope it was helpful. :)

SOURCE: freezer stopped making ice two days ago. Today fridge and freezer warm

Check the defrost timer. Rotate the dial on it to see if anything changes.

Fridge freezer stoping after 24 hrs


most of these freezers have an automatic defrost cycle.
after so many hours of chilling it will stop and run a de-icing cycle.
this is accomplished by one or two heating elements.
if one of the elements is burned out it will not run the defrost cycle.
and will ice up quickly.
depending on the model the heaters will usually cost about 15 to 20 dollars and they are easy to replace.
look up the model of your freezer and download the pdf files they will usually have a pictorial diagram showing the location
a defrost timer usually does nt fail on them unless it is physically damaged.

The freezer cools half way top, below is warm.


If there is no cooling at all on the fridge section but the freezer works then it is confirmed that the compressor and gas pressure is OK. Now shut off the fridge and leave it powered off while you clean and check the evaporator for frost. If frost is seen it is a good indication as the compressor is working with sufficient gas within.
Now after about 6 hours plug in the fridge to start. Observe cooling to happen in about one hour and ice to from under three hours.
Earlier make sure that the thermostat was set to normal mode for freezer and fridge.
However if ice forms in the freezer then observe the fridge for about 24 hours for cooling to continue and the fridge to cut off . If not the auto defrost timer, or the thermostat must be checked. Frost formation without defrosting could block the air flow and so shut the air passage to the fridge. Also the blower fan must work and if this is not working then the fan can be faulty. Also a fault on the control unit is a suspect to non functioning of any one of these components.
If defrost timer works but frost keeps forming check while the compressor shuts if the heaters are working, check continuity of the heaters.
So try this test using a multi-meter on the defrost timer and the thermostat and make your observations so that we come to the solution.

Not freezing


Either the defrost circuit has failed or the refrigerant is low - my money is on the defrost circuit.

Most defrost circuits have three main parts:

1) defrost electric heating coil
2) defrost terminator
3) defrost timer.

The heating coil and terminator are in the freezer compartment - behind a protective panel. The heater is usually piggy-backed on the freezer coil and the terminator is in contact with the freezer coil to detect its temperature. The defrost timer is a simple assembly of a clock motor with switch contacts that can be located anywhere the manufacturer desires. The timer turns on or enables the defrost circuit every 8 or so hours for up to 30 minutes give or take.

When the timer has enabled the defrost cycle, the cooling mode ceases; the compressor shuts off and power is sent through the terminator to the heater. The heater warms and melts any ice build up on the freezer coil. The water drips to a pan and flows down the tube to a pan under the fridge - where it is evaporated off. The heater warms the freezer coil until either a) the timer returns to cooling mode or b) the terminator senses a preset rising temperature on the freezer coil. Once either condition is present, power is interupted and heating stops. The compressor is energized through the adjustable thermostat in your fridge. Since it is warm, the compressor turns on and cooling begins.

If any of the components listed above (1,2 or 3) have failed, the defrost cycle never warms the freezer coil and the ice never melts to clear the freezer coil as intended. Air can not be circulated through the freezer coil since it is choked with ice, so even though the compressor runs, the fridge and freezer spaces never get colder. The adjustable thermostat never sees the temperature you've set so the compressor never shuts off.

Water dripping in the fridge is melting ice from the freezer space - as the freezer is not getting colder - only the protected space around the freezer coil is.

To fix this, you'll have to get the service manual or schematics for the fridge to determine where the parts are located and do some troubleshooting with a multimeter after disassembling the freezer compartment and wherever else to access the timer if needed. This is not a good first appliance repair job for a DIYer due to the danger of refrigerant and testing live electrical parts in closed in spaces.

I hope this helps.

Had a fridge freezer in garage. Just found that


more than likely the defroster inside the freezer has gone bad. This defroster is located in the space between the fridge and freezer and activates to defrost the freezer and stop build up of ice in the freezer.. If it is bad the freezer will not keep the fridge nor freezer cold.

My fridge freezer is running non stop


It is probably because it's not getting cold enough to cut off. If you slowly turn the thermostat to warmer it should cut off when it gets to that temp.If it doesn't cut off then it is a thermostat problem. When you have heavy ice buildup on the evaporator coils inside the freezer behind the back panel that will hamper the cooling. This is caused by a defrost system failure.

Fridge freezer side by side running constantly but not cooling.


Make it a habit to defrost it every week. You see, when ice forms around the evaporator tubes (which runs around the walls of fridge and freezer), heat exchange reduces (that means heat is no longer absorbed from the things inside the refrigerator) and cooling stops. See whether freezer walls or fridge walls are damaged. Do not use knives or any other sharp tools to remove ice. Do not forcefully remove items that are difficult to take out from the freezer. Defrost and remove them.
