Fan stopped .Compressor runs . - Heating & Cooling

Question edited for clarity, MAKER.
Question moved to Model Category.

Your fridge freezer has three fans.

The compressor evaporator fan cuts in and out as required to maintain temperature.

The fridge evaporator circulation fan runs to maintain an even temperature. It stops when to open the door and resumes when you close it and stops when the set temperature is reached as long as the compressor isn't running. If the compressor is running, the fan normally runs to prevent icing which happens slowly.

The freezer also has a fan, and that runs pretty much all the time unless target temperature is met and the compressor is not running. This fan runs when you open the door to stop the moist air from the room freezing on contact to the 0'F, -18'C evaporator fins. The fan keeps the air moving to deposit less frost.

It sounds like your is running normally except for the noise. Trace the noise and find it. The compressor fan has a Shark Paper fibre board cover and these often distort over time and touch the fan blades. That is the common cause. The less common cause is the internal fans pinging off built up ice that should have been removed during the defrost cycle.

Possibly a tstat issue. Run system until satisfied, once satisfied indoor fan shuts down compressor still runs remove tstat face plate and see if compressor shuts down. Another issue could be a sticking contactor for compressor. With a meter you could check at the contactor to see if you lose your 24volts for cooling but contactor remains pulled in.

Check the defrost relay

Likely needs a new fan motor. So the fan stops, compressor keeps running until it overheats as well, correct?

The compressor will appear to freeze up if the evaporator fan stops running while the compressor is running. I would look for a defective evaporator fan if I understand you correctly. Fans will sometimes stop when they should be running. Defective fan does not always stop running when they go bad

The fan only runs when the compressor runs. It stops when the defrost cycle runs. It can be hard to hear the compressor. If possible leave the refrigerator door open for a short time and set the temp cold. The fan should run and start unassisted. You can xheck for air flow from the compressor fan . The air will flow from the grill in the front, I would expect the internal freezer and external compressor fan to operate at the same time.

Condenser fan motor or motor wiring is bad. That compressor should never run without the fan. Good luck.

old subzeros the CONDENSER FAN MOTOR RUNS OLD THE TIME. SAME WHIT THE EVAPORATOR FAN MOTOR. RUNS ALL THE TIME. now fos systems whit 2 compressor the condenser fan motor run for both compressor. only stop when both compressor stop......

Replace the motherboard (part # WR55X10942) but be careful to check that the evaporator fan (inside the freezer) turns on when you power up the refrig again. A bad evaporator fan motor can take out the motherboard. If compressor starts with new board but not evap fan, unplug immeadiatelly and replace the evap fan motor to save new board.

Relay for the compressor may be stuck ( Contacts welded) both the fan and the compressor should operate at the same time. Have the relay(s) checked and possibly replaced.
