Question about Refrigerators

1 Answer

The compressor on my Whirlpool wbm46 fridge is cutting out on overload. The compressor is running very hot and trips on thermal overload and then restarts once cooled down. The fridge is only 3.5 years old and has been well looked after. Is it worth cost wise to replace the compressor if its US. Cheers

Hello there:
first you might want to have the compressor recharged with refrigerant these hermatic units will over time loose some of the refrigerant and will need to be recharged and this would be a lot cheeper to do than replacing the compressor if your warranty is still good i would use it ok?
best regards michael

Why is my refrigerator cutting off for 15-30 monutes?

Compressor is tripping on thermal overload(it's hot!). It is possibly hot from running with a dirty condensor, make sure the condensor is cleaned. Some refrigerators have a big grid type coil on the back and some are located underneath where the compressor is and cooled by a fan motor. If it has a fan motor, the motor may have failed as well. If condensor needs cleaning I suggest taking it outside and washing with hose.

If the refrigerator has a refrigerant leak, it could cause the compressor to overheat for a few reasons as well.

Compressor lock up is another possibility, could be caused by loss of refrigerant( which would cause a lack of oil/ or lack of oil returning from the system back to the compressor. Compressor would have to be changed and leak located or repaired. It usually is cheaper to just buy a new fridge

I have a whirlpool ed26qf that stopped cooling. the compressor is very hot and is clicking off and on. is there an easy fix or easy way to find the problem

The compressor is overheating and tripping on thermal overload. Check the condenser and find out if it's dirty. Most of the time, people don't realize the condenser, is usually located under the unit. They get filthy and can't reject the heat the refrigerant picks up in the box. If that's not it, you're probably either low on gas or your compressor is going bad.

I have a whirlpool fridge/freezer which after a power cut will now only register 7 on the freezer, although still seems quite cold. How can I get it back to -18 ? Thanks

If the power loss was for 5 mins of less.... just unplug it for 20 mins and plug it back in. The compressor is probably "High side cycling" and the thermal overload is tripping on the compressor every 4 - 5 minutes for about 40 seconds. Unplugging it 20 minutes will allow the coolant system to stabilize and the compressor to re-start.

Will not cool fan runs though

It sounds as if the compressor has gone out. To see if it is out you need to pull the fridge out to access the lower part of the fridge. There will be a black oval tub looking device in back of a fan. Plug the unit in and see if the compressor kicks in you will hear a humming noise from this device. You can put your hand on it to see if it is vibrating but be careful if it has gone into thermal overload it will be very hot. You may want to unplug the fridge for approx 4 hours or so before attempting to check this since if it is in thermal overload it will not start so the time it is unplugged it will cool down and start. Once you plug it back in check to see if the compressor is humming by listening to it or feeling it. It may run fine from this point out or it may go back into thermal overload in which case the compressor has gone out.

Hope for the best good luck.

My refrigerator is not cooling or freezing. It is a side by side about 9 yr old not sure of the M # fan runs and I hear something clicking on and off. whats the problem and can this be fixed. Mike

That is your compressor overload. Replace the overload, start relay and start capacitor and you should be good to go! It's easy Sea Breeze

Continues to make ice when grill cover is off, then trips on safety limit #2 when replaced. condensor has been fully cleaned

If this is a combination gas grill with the accessory fridge mounted in the cabinet, then the issue is that once you put the grill cover on, you are preventing proper airflow/circulation needed to keep the fridge's compressor ventilated enough to keep operating.

Try leaving the grill cover off and move the grill/fridge out of direct sunlight, as the thermal heating of the cabinet isn't helping the fridge get enough air circulation to help it (the compressor) run cool enough to keep from tripping the thermal overload sensor (thermistor or Klicxon themal protection device) mounted on the compressor.

This device prevents the compressor from extreme heating that can cause the compressor have a catastrophic failure.

Hope you find this Very Helpful and best regards!

Whirpool GS6SHAXLB03 Refrigerator or freezer do not cool.

This sounds like it's out of freon. Not just low but out. That clicking noise is a thermal overload shutting down the compressor. If you continue let it just click away it will burn this overload out and the compressor will have to be replaced. If the refrigerator just started doing this suddenly it could be that the compressor is locked up. If it has external capacitors either the start or run capacitor could be bad. If the capacitors are good then you could try a hard start kit to try to unlock the compressor.

Frig or freezer will not get cold. the fan still runs.

That is the thermal overload tripping because compressor is hot. Unplug and let cool off.

Compressor runs 12 seconds then down 2-3minutes

It sounds like you have a blockage in the refrigeration system. This would cause the compressor to overheat and ultimately trip out on thermal overload.

KitchenAid fridg compressor heating up

If the compressor is very hot, it sounds like it may be locked up. Is there an external fan next to it that is not running. this will cause the comp. to overheat, like a dirty coil, which it sounds like you checked out. There is a thermal overload on the compressor. Its underneath the little plastic cover that the wires go to. It protects the compressor from a meltdown. It also has a relay in there. If you have an amp meter you can check this by waiting for it to cool off and clamp it on one of the compressor wires.when it clicks on, If the amps soar over 20 very quickly, and then stops. Its a locked compressor and the thermal overload is cutting it out. If you don't have a volt/amp meter, then try replacing the relay as its pretty cheap. But I would bet on the comp. as long as the fan is running.
