It chills properly but when fan turns on it makes this squealing sound

Sounds like a compressor or a condensing fan motor. If it is the fan motor most of the local motor supply houses carry them.

most of the time it is the water pump is going bad. It squeals real loud.

Diagram not needed, check the thermo fuse and sensor, they all connect to the chill plates and easly removed (round object 1.5cm with 2 wires to it.) and you may also see a 10mm clear tube with a sensor in it, this one will have a wire at each end, if you can, replace both, it will save you grief from only doing one and find ?????? you know what I mean. These sensors tell the fan to start at a preset temp, Sounds hard but I am pretty sure this is the issue and very easy to do.

Hope you have some success with this, dont forget to vote, I did this for free. Regards Russ

Sounds like a thermostat not making the circuit after a few cycles

if the evap fan is not turning try to turn it by hand a few times then start you freezer if it does not turn it needs to be replaced.make sure there is no ice build up on the evap coils.alos check the continuity of the defrost heater below the evap coils.once you het teh fan replace your unit should cool down to the proper temps.

Check the fan that moves the air from the freezer side to the refrigerator side. It is either stuck in ice or not working. Defrost the refrigerator for 24 hours and then restart it Listen for the fan operation be aware that the fan may shut off when you open the door, so listen closely. Defrosting it may fix or the fan may need to be replaced.

First, make sure the refrigerant coils underneath the unit are not dirty. If so, clean them off.

Second, make sure the compressor (underneath the refrigerator) is running.

Third, make sure the compressor fan (underneath the refrigerator close to the compressor) is turning. This fan should always be turning when the compressor is running. It removes heat from the refrigerant coils and transfers it to the outside.

Fourth, make certain the evaporator fan (in the freezer, likely behind an access panel) is turning.

All of these conditions must be present for proper cooling.

First, check the compressor fan. Make sure it is turning. If this fan is not working properly, the refrigerant will be be cooled adequately. This lowers the efficiency of the refrigerator and causes it to run more.

The fan is probably located in the back of the bottom of the refrigerator. It pulls air across the coils and blows the heat out the back of the unit.

If the fan is not turning, the fan motor will need to be replaced.

It sounds like the freezer fan(evaporator) is wearing out. This problem is very hard to diagnose because the fan spins but no fast enough to circulated the chilled air thru the freezer and refrigerator. The parts and labor are around $300.00

Sounds like the freezer/refrigerator circulating fan is wearing out. When this fan starts to wear out the fans force is reduced to a point that it will keep the freezer cold, but doesn't have enough force to circulate air thru the refrigerator. The minimum cost to repair this problem is around $300.00
