Hello,

I would like to submit a problem I am currently having with my 2 side fridge.

The refrigerator doesn't stop running (fanning). The temperature inside the freezer and the refrigerator are correct. So it means when I set to 4F, the freezer will get to 4F. When I set the refrigerator to 34F, the temperature inside is 34F.

I did this experiment and set a lower temperature for the fridge and the freezer. Let's say -2F for freezer, 33F for the regrigerator.
When the temperatures are reached for the freezer and the fridge, I increase the temperature to a higher temperature (6F/37F) ==> The fridge stops (no fanning any more).

But when the temperature comes back to 6F and 37F, it doesn't stop fanning again.

What could be the problem?

I was thinking that the power of the compressor could be weaker than it was before.
I checked the door seal with a business card and it doesn't look in bad shape.

What am I missing?

Thanks a lot for helping

The most common problem that causes a refrigerator to run continuously is a dirty condensor or poor air flow across the condensor coils. Check for any frost or ice build up on the evaporator coils. Compressors normally run warm to very warm. A compressor that is running hot to extremely hot usually indicates a problem in the system.

Hello Rick, thanks for your reply.
The condensor is very clean and I cleaned the air flow a while ago.

Still a mystery.

The problem is that it never stops running (fanning).
Before it was not like that. When the temperature was reached, the fan was turning off.

Yes that's correct. The compressor doesn't stop running (since I can still hear the fan running).

So you're saying since you can hear the condensor fan running, the compressor must be running? Is the compressor running cool warm or hot?

Yes that’s the implication I am making. Fan—>compressor

The compressor is running cool

Thanks again

OK, Just to make sure we are on the same page, the condensor fan motor is next to the compressor. The evaporator fan motor is in the freezer section just above the evaporator. The fan you hear running is the condensor fan motor next to the compressor. Is that correct?

Your machine uses an inverter compressor. The compressor is a reciprocating, variable-speed, 4-pole type. It operates on 3-phase, 80 to 240 VAC. They may run longer but use less energy. Inverter compressors are extremely quiet and run at or just above room temperature. It's hard to tell if the compressor is running without placing your hand on the compressor and feeling for the vibration. So what you hear is the condensor fan motor running all the time. On models with a standard compressor the condensor fan motor is wired in parallel with the compressor. Whenever the compressor is running the condensor fan motor will running. On inverter compressors the condensor fan motor is controlled by the main control board. If the compressor is running 100% of the time you could have a sealed system issue like a refrigerant leak or partial restriction. That seems unlikely since it maintains the temperature where you set it. If the back cover over the machine compartment is not installed you will have long run times.

Hello Rick,
I just enclosed the picture of the fan I am talking about. Yes as you describe it is the fan next to the compressor.
That's the one constantly running.


"If the compressor is running 100% of the time you could have a sealed system issue like a refrigerant leak or partial restriction"

Let's assume that's the problem. What can I do? Just getting rid of the fridge and change one?


One more information that I should have specified: this fridge was off for 1.5 year. Can it be a problem?


Thanks for all your messages, that really helps.

Sealed system repairs are expensive and will often exceed the machines value. The only way to check the sealed system is by connecting a set of refrigeration gauges to the system.

I think that's going to exceed my level of competence in fridge repair and also the set of "gears' I have at home to fix it.
Thanks again Rick. That was very interesting and helpful.
