It might be the timer motor, if it doesn't run. neither does the timer. Easily replaceable and cheap. good luck. John

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.

Ice forms on the bottom. Looks like an iceberg


DEFROST PROBLEM
The evaporator coil behind the cover on the back wall inside the freezer will ice up under normal conditions. Every 8 to 10 hours for around 20 minutes the defrost timer (or in most newer models the electronic adaptive defrost control) will turn the defrost heater on to melt the built up ice. There is a defrost thermostat which prevents the heater from overheating the freezer by breaking the heater circuit when the temp reaches close to 32 degrees F. The entire cooling system shuts off during the defrost cycle and starts back when the timer advances through the cycle.

If this ice is not melted it will continue to build up until the air can't flow over the coil to circulate the cold air through the freezer and into the fridge. The temperature change in the fridge is usually noticed first followed by the freezer.

If the defrost thermostat is bad, it can prevent the heater from coming on OR it won't turn the heater off when it gets too warm. It is clamped to the evaporator coil at the top to sense the temp. If it appears to be misshapen it is bad.
With an ohm meter it should show continuity when cold and none when warm.
You can also bypass(disconnect the two wires plugged into it and twist them together) the thermostat to see if the heater comes on then. If it does then you know the thermostat is bad and needs replaced.

The defrost heater is located on the evaporator. It is in a tube which is at the bottom and can also go up the sides of the evaporator. On some types you can see a burnt spot if it's bad. With an ohm meter it should show continuity from end to end when disconnected from the wiring in the freezer. You can also test the wiring for voltage when it's in the defrost mode.

If you have a defrost timer you can test it. It can be located under the fridge behind the kick panel on the front. Some are in the fridge with the controls at the top. You can turn the defrost timer till it clicks and everything shuts down. The heater should now come on. If it does, replace the timer because that means the timer is not running. If it doesn't, check the heater and defrost thermostat. Turn the timer again till everything starts back up to end the defrost cycle.

If you have an adaptive defrost control instead of a timer, replace it if the heater and thermostat test good. It is located in the fridge with the controls in some models and on the back in others.

BEKO CA541FF - 4 Years Old Fridge is OK at 4c to 5c Freezer -5c to -4c Cannot now hear gurgling noise of cooling cycle What should I check first? Thanks, Duncan


You only hear the gurgling when the compressor cuts off so it must be running all the time and still not getting cold enough in the freezer. This sounds like a defrost problem.

Sides of freezer are hotter than normal. no air sound when closing door,is this a defroster problem?

My admiral fridge/freezer runs a lot but does not get down to temperature


If the evaporator coils behind the back panel of the freezer are icing up because of auto defrost failure that will stop the circulation of cold air and eventually affect the freezer too.

check defrost timer, defrost heater, defrost thermostat. In most newer models the timer has been replaced by an electronic control board. If the heater and thermostat are ok it’ll be the control.

You can turn the defrost timer till it clicks and everything shuts down. The heater should now come on. If it does, replace the timer. If it doesn't, check the heater and defrost thermostat. Turn the timer again till everything starts back up to end the defrost cycle.

Turbo air freezer


Check the time setting on the defrost timer. It may not be set to the correct number of minutes for defrost. Compare it with the side that is working properly for the right time of the cycle.
