This may just be vibration. the compressor has 3-4 rubber feet between the compressor and the frame on the freezer. check for dry rot or any direct contact between the 2 components

If Klixon relay attached to my compressor rattles, is it definitely no goad?


If the relay was faulty, the compressor would not start when cold. To test the relay put a continuity meter in the 2 pins for common and start. there should be no reading. Turn it upside down there should be continuity. If there is a capacitor attached to the relay as well, change it as it may be failing. Apart from these, check all else is working ok, particularly the condenser fan and gas level. if all else is ok, the compressor is overheating and siezing and will need replacing.

I have a small magic chef freezer that opens from the top. I has about 3 or 4 cu. ft. of freezer space. Lately a buzzer has been going off every 15 or 20 minutes. It buzzes for about 5-10 seconds and then...


With the time as the compressor gets old the buzzing will increased, its not a bid deal, just set the thermostat to 1 during the winter, saves you energy and give the compressor more time to rest.

After loading freezer a loud buzzing sound started


Is it coming from inside the freezer or outside? If outside either the auto defrost timer is a problem. If the noise comes from the compressor, almost certainly the starter relay inside the electrical cover needs to be replaced. It can be purchased at most refrigeration outlets. If coming from inside, you need to defrost the freezer properly for 12 hours then restart. The noise should go away then.

Does not cool and compressor relay keeps intermittently buzzing every 1 to 2 minutes. Condenser coils are cleaned and when you check across the overload protector pins there is no continuity.


When there's not continuity across the overload is because the compresor overheated , it could be the relay or the compressor that is burned out or stuck .I would let the compresor coold down for a few hours (unplugging the unit) and replace the relay (no more than $20) and if still having problems the compressor needs to be replaced.

Whirlpool upright freezer making buzzing noise and not working


I had a similar problem yesterday. I woke up and the freezer was not working anymore. It would make a buzzing noise and then it would click and shut off. I looked online for some possible solutions. Here is what I did:
I unplugged the fridge. I pulled it out and took off the cardboard backing. I used an air compressor to blow out all of the dust and dirt that had accumulated on the condenser coils. A shop-vac just wasn't powerful enough to pull out all of the dust/dirt. After that, I plugged it back in....and the same thing was happening. It would buzz, and then it would click off. I figured out that the "click" was coming from a starter relay (a small plastic piece attached to the big black compressor). I detached the plug from the relay and then detached the relay from the compressor. The relay was burned out. It turns out this is a common problem with the relay. I replaced the relay for $50 (from an appliance parts store) and put the whole thing back together in about 10 minutes.
I plugged the fridge back in and the compressor started, and now the freezer works better than other. I saved about $400 doing it myself, all in about one hour. And better yet, my wife was very impressed. Not bad for a doctor.

Buzzing noise -Kyoto KU 9577 Freezer


you may have a bad compressor or a bad compressor relay. The buzzing noise sounds like the compressor trying to start but can't. Unplug the unit and pull the relay off the compressor. If it rattles like gravel in side it replace the relay. If it doesn't then you may need to call a repairman to check the compressor. Hope this helps.

Buzzing compressor


heres a part number for the overload relay assy 5304468029.. its mounted on the side of compressor. its a tricky one, usually my experience has been the noise comes from a bad compressor( which you should have 5 year full warr from manufacture). sometimes the overload relay does go bad preventing compressor from starting,the n ew compressor will come with a new overload relay
