SOURCE: Fridge compartment is freezing in

have you tried turning down the temperature for the freezer or fridge? The fridge gets its cold power from the freezer, it is siphoned into it. So turning down the freezer temp may help but a sensor may have gone bad in the motherboard of your freezer and not closing off the vent into your fridge

SOURCE: my refrigerator won't stay cool but my freezer works fine

You have something wrong with the vent going from the freezer to the fridge. You probably have a defrost problem and ice is blocking the vent that goes from the freezer and comes out in the roof of the rerigerator compartment. Replace your defrost timer and bimetal.

SOURCE: Fisher and Paykel N500B fridge freezer. Freezer not freezing

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 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.

DEFY F640 Fridge/Freezer side by side. The freezer made clicking sound, and green light flicker for a while then stops. Now it is not freezing anymore.


Hallo

It could be the theromstat, clicksen or the compressor.
But I think its the clicksen it is faulty and can't handle the amp stress test I hope for your sake other wise I believe its the compressor.

Freezer motor not restarting after it switches off.


Hello Rostakes;

My name is Peter. I am a retired field service refrigeration technician.

When you unplug your unit, then plug it back in you are giving the motor a surge charge with more volts than necessary to run the motor.
A bad evaporator motor will hum. The clicking sound that you hear is the motor fan blade striking something.

You need to check for 2 possible causes:

1.) The back cover in your freezer, that is in front of the evaporator motor and fan is very thin sheet metal and will easily flex. Inspect to ensure that you are not over packing your freezer and pushing against the back cover.

2.) It is common for the evaporator motor fan blade to have interference from icing. Inspect the back cover in front of the evaporator fan for frost and ice. Your freezer goes through a defrost cycle where the unit shuts approximately every 8-10 hours, the defrost heater turns on for about 20 minutes, the unit restarts. This is where they get the term; "Frost Free". If you have frost or ice on the back wall your defrost heater and Bi-Metl need to be replaced.

Due to the limited size of response by the site I can not walk you through the repair procedure for these parts. If necessary submit this repair procedure request to this web site.
