Refrigerator not cooling if plugged in for more than a few days

Good day,

My fridge is a Maytag model MBF2256HES.

A few months ago, I noticed that it was failing to cool both the freezer and the fridge. I unplugged it, got a repairman to come have a look and the first thing he told was that he couldn’t do anything since I had unplugged it.

After paying the service call and plugging it back in, I realized that it actually worked again. So I cancelled the second appointment. Unfortunately, it only worked for a few days before it started to get warm inside again…

Now I’d like to give it a shot myself. I removed the back panel and filmed it through of it’s cycles as it attempts to cool. It makes a clicking sound and then a buzzing like “something is trying to do something”. Maybe the compressor to start compressing the gas? I wanted to capture two cycles, so the video is a bit long. The first cycle is at the very start and the second is just before the two minute mark. There’s nothing really interesting between the two.

Also, the compressor is warm to the touch if I leave the fridge plugged in (even if no cooling is happening inside).

Link to the video.

From reading other posts on this forum, it doesn’t seem to be the start relay. But then again, since the compressor is getting hot, I’m assuming the problem is elsewhere? Also, it’s pretty dirty down there, but from what I can see, the condenser coil is fairly clean. So I’m a bit at a loss.

If anyone can point me in the right direction, it would be greatly appreciated!

Thanks (and congratulations for making it through this long post!) :-)

David

Let’s start with the more common solutions:

Cause 1

Condenser Coils are Dirty

The condenser coils are usually located under the refrigerator. They dissipate heat as refrigerant passes through them. If the condenser coils are dirty, they won’t dissipate the heat effectively. As debris builds up on the coils, the refrigerator becomes less efficient, causing the refrigerator to work harder to cool down. If the coils are significantly dirty, the refrigerator will not be able to maintain the proper temperature. Check the condenser coils to determine if they are dirty—if the condenser coils are dirty, clean them.

Cause 2

Condenser Fan Motor

The condenser fan motor draws air though the condenser coils and over the compressor. If the condenser fan motor is not working properly, the refrigerator won’t cool properly. To determine if the fan motor is defective, first check the fan blade for obstructions. Next, try turning the fan motor blade by hand. If the blade does not spin freely, replace the condenser fan motor. If no obstructions are present and the fan blade spins freely, use a multimeter to test the fan motor for continuity. If the condenser fan motor does not have continuity, replace it.

Cause 3

Evaporator Fan Motor

The evaporator fan motor draws air over the evaporator (cooling) coils and circulates it throughout the refrigerator and freezer compartments. Some refrigerators have more than one evaporator fan motor. On refrigerators with only one evaporator, the evaporator is located in the freezer compartment. If the evaporator fan is not working, it will not circulate the cold air to the refrigerator compartment. If this occurs, the freezer may still get cold, while the refrigerator will not get cold. To determine if the evaporator fan motor is defective, try turning the fan blade by hand. If the fan blade does not turn freely, replace the fan motor. Additionally, if the motor is unusually noisy, replace it. Finally, if the motor does not run at all, use a multimeter to test the motor windings for continuity. If the windings do not have continuity, replace the evaporator fan motor.
