Question about Refrigerators

1 Answer

Compressor cycling at 1 hz

The refrigerator is cycling about once per second with what sounds like the compressor motor coming on then a relay clicking off then cycling again.Also, each time before the relay clicks off - the amp loads increase such that the refrig light bulb and other light bulbs on the circuit dim for a fraction of a second.This started happening a couple days ago - but would eventually correct and run fine. The problem also seems to occur when the power goes off. (live on a large boat and we have been having to disconnect power to boat a few times.Thanks.Wayne Bailey

    hey thanks a lot.

    I have switched power supplies. We live on a boat so I started generator with good extension cord going to refrig to double check everything.

    Have service guy coming tomorrow.

    Thanks again for your time.

    Service guy came here and it was the compressor relay on the PC board located on the back of the refrig. Guy says he sees it all the time and knew what it was as soon as he heard it start.

    Board cost - 150.00

    Labor to replace board (4 plugs) - 150.00 (&%#@!)

    Cold Fridge - Priceless

    Thanks for the help.

Check and confirm that your power supply is good. Also try plugging into a different outlet. Your compressor is cutting out on thermal overload due to high amperage draw which is caused by either low voltage supplied or an internal breakdown of the insulation on the windings. If you have confirmed that your power supply is good and this still happens, you will have to replace the compressor.

Admiral HMG61139 21.1 cu ft Side-by side refrigerator, not cooling. clicking sound every few minutes. (sounds similar to oven thermostat or relay coming on).


Thier is one of a couple things going on with your refrig.

The start relay on the compressor is bad so what your hearing is the overload thermostat tripping on and off and keeps trying to start the compressor

The fan motor by the compressor called the condenser fan motor is not running to cool the compressor so once and what you overload keep trying to start the compressor but its too hot to start

Finally the compressor is locked up and the overload still keeps trying to start it but its totally seazed and ain't going to run

I hope this helps you to determine what is wrong with your refrigerator,

Relay keeps clicking on and off

We aren't sure either without putting a tester called an "Annie" on your compressor. Maytag has had a lot of compressor failures, and we have installed overload relays on some of these refrigerators, the compressors ran fine and pulled perfect amps, and hours later the compressors failed anyway. You can remove the overload relay from the compressor, and do a continuity check on the three terminals. You should get continuity between all three, and you should not get any continuity between any terminal and the compressor case or freon lines. If the compressor tests fine, then it is usually, not always, a bad overload relay. If the compressor tests bad, then your refer is not worth repair, usually a 900 to 1100.00 repair in my area in Seattle. You may still have a warrantee on it as most brands still have a full 5 year warrantee on the compressor. Good Luck, Appliance Specialists.

Whirlpool refrigerator model ED25PQ. Interior warm

possibly the relay on compressor is bad. the relay will need to be removed. shake it, if it rattles and or particles fall out of it, it is bad.

CTB1722GRW compressor clicking on for 20 to 30 seconds then off.

it depends on how severe the power spike on the outage was,if your lucky it may just be the contactor,if not comp time,you can open the contactor case and manually start the compressor,use an insulated non-metallic device to do so
