I have a Haier mini fridge that is not working. I have taken the P6R8MC relay off but don't hear any rattle. Does that mean the compressor is probably bad?


That is what is sounds like but let's check. An overload relay will fail due to wear, a short or a bad compressor will knock it out. There is a rare occasion you may purchased a bad overload relay, but that is rare. The rattling of the overload relay is a good indicator it is bad, however it does not have to rattle to be bad - inspect for burn marks as well.
The clicking sound is the overload relay trying to start the compressor. There will be a pause and then click trying to start the compressor again.
Remove the overload relay component and expose the three pins on the compressor. Using a multi- meter, measure the Ohms across the three pins. You will get one high Ohm reading and two lower Ohm readings. If the two lower readings add up to the higher reading the compressor is good. Make sure the green ground wire is securely grounded. It could nock out the overload. Check for loose connections. Replacing a compressor is a major repair. The cost will exceed the purchase price. Rule of thumb; "If the cost of the repair is 1/3 or more of the purchase price of the unit, Buy new".
As a retired Sears service technician, we considered these units
as throw-a-ways due to the high cost of repair. If you had a service contract we would replace the unit rather than repair it

Not freezing or cooling and compressor clicking on and off


From your description it sounds like the start components (start relay, overload and capacitor) are having problems. The clicking you hear is probably the overload kicking out to protect the compressor. It is quite possible that the compressor simply has gotten too hot and after sitting a while will restart when plugged back in. The start components are not generally considered 'user serviceable' parts. When the compressor has cooled to pretty much room temp, plug it in and be listening for those clicks. If you hear them, unplug it because it could eventually damage the compressor. Those components give the compressor an extra jolt to get the compressor running then they drop out of the circuit. If the compressor doesn't start, it creates heat until the overload drops out.

I have a haier mini fridge model #HSW02C when i plug it in it humms for a few seconds then it clicks then i hear nothing could this be the relay? any sugestions?


I would say that the motor is humming because it is not turning and the click is when the overload control switches the power off. It may be a start run capacitor blown out but it may be a seized compressor motor. have a fridge mechanic check it out.

Fridge noise/


You need to get a repair man to your house ASAP. This noise you are hearing is the compressor start relay and the click sound is the overload protector heating up and shutting it off. You may have a defective relay, or possibly a bad compressor. The relay and overload are attatched to the compressor in the back of the fridge.
Check your owner's manual to see what kind of a warranty you have on the "sealed system" Hopefully the parts at least will be covered should you need a new compressor.
Sometimes if the compressor is bad on these models you can let it sit un plugged for a couple hours and try to re-start it.
Good luck to you!!

My mini fridge will not work. compressor is hot.


Believe you need to change the start relay and overload, Sea Breeze

Freezer and fridge is warm


Sounds like the motor start relay and capacitor both need to be changed. The clicking is the overload cutting off power to compressor because it will not start. It will need a better start capacitor also to get it going again. Keep it unplugged until the parts can be tested and replaced. If not the internal overload may be damaged.

Frigidaire PLHS268ZCB1 freezer not freezing, periodic humming sound, Cold air instead of warm coming from vent underneath


Periodic humming is the control relay closing to start the compressor, only the compressor is not able to start. There is a lot of (inrush) current during this event so, after a few seconds, an overload cuts the power to the compressor and the humming goes away. About 30-60 seconds later, the relay tries again, the compressor hums but doesn't start, overload cuts power, rinse and repeat. If you touch the compressor during this cycling, it should be very hot. It's possible that the starter relay is bad. If you look at the compressor, there is a black box that plugs into the compressor on one end and has conductors connected to the other end. This is the relay / overload and can easily be replaced. There's also a capacitor plugged into that relay/overload. Be sure to discharge it or it can give you a shock. The capacitor on your model is a running cap, not a starting cap. Unfortunately, the most likely cause for the humming is your compressor starting to fail. This model is known for an unusually high compressor failure rate. You can replace the relay / overload with a "hard start" relay that is compatible with the compressor. This "should" extend the useful life of the compressor a bit but it will still eventually fail. The compressor may also be permanently damaged by the cycling so even the hard start may not solve your problem. It's a cheap part, however, and worth a try. Is it worth replacing a compressor? It's a sealed system and needs a professional with the right tools to perform the work. Usually it's between $400-$700. A comparable but brand new fridge is ~$1000. You'll have to weigh the cost. It's very likely that a $500 repair will get you several more years out of your existing fridge. Some would argue that for a few hundred extra dollars, however, it's worth the money to get a new one that's more efficient and under warranty.
