Re: Replying to your answer
Te relay is located at the side of the compressor. it is covered in a plastic cover and the wires are attached to it.
if you can take a snap shot and post it here, i could help you check it. also if there is a capacitor near the compressor and the wires are attached to the relay also, then check the capacitor also. if you have a bad capacitor, the compressor would not start also.
a 6ya Repairman can help you resolve that issue over the phone in a minute or two.

trace the wiring of the reversing valve.. its an electromagnetic relay in the middle of a cluster of tubing near the compressor. depending on its normal state when un-powered (normal heat or normal cool) the tech may have simply disconnected the relay (normal cool), or connected it directly to the call-for-cool line (typically yellow) (normal heat) regardless of heating or cooling, the compressor always runs the same direction
bad compressor relay on control board. The relay is not opening the circuit, allowing the compressor to stay running when unit is turned off. This overheats the compressor and opens a thermal disk shutting the compressor off. When thermal disk cools down, the compressor restarts under load and trips breaker.
Compressor is tripping on overload. You may just need the overload and relay replaced due to a bad compressor relay. The relay is what switches the compressor from it's start winding to it's run winding. If you pull the relay off, shake it to see if you hear lots of rattling inside, that's a sure sign of a bad relay. I would replace both of them. Here is the overload relay to order. Here is the start relay to order.
Hi, That is because there is a wire shorted in the unit or the compressor is locked up and has gone bad... The most likely thing is that the compressor is bad... it will cost more to replace it then the unit is worth...
Here is a tip about troubleshooting your air conditioner...
There are many things that can cause your air conditioner not to cool...
it off completely and let is cool over night and then plug it back in
and see if the fan runs and if the compressor runs...
compressor runs but not the fan then check for voltage going to the fan
and replace as needed...if there is no voltage then trace bad to see if
the main board is bad...
Start relay and capacitor may be bad if
the compressor does not run after getting completely cooled down...
Check out these tips that I wrote about that... it is a greatplace to
start trouble shooting your unit...and something that you can dorather
then calling a repair person to do a simple thing for you...
The clicking noise you hear is the compressor trying to start but the overload is tripping that is hooked to the compressor. Either you have a bad start relay which I would replace first or your compressor is locked up. If the unit is under five yrs old but older than January 08 then the compressor not the relay is under warranty. Jan 08 manufactorers have put a one yr warranty on compressors. Its real easy to replace the start components on the compressor. Unplug first then take back panel off. If the compressor is hot more than likely the compressor valves are bad and wont pump which overamps then trips overload. Then resets and tries again. But if compressor is cool then you should be able to replace start relay and compressor should start up. Those relays usually get too hot from dirty coils and/or a bad fan motor by the compressor that blows air across it to keep it cooler. But the cost of new fridges is an incentive to try the relay. Hope this helps.
The relay mounts on the compressor and has a sliding start switch inside it. If you shake it you should feel the sliding switch within it. I fyou hear nothing or it sounds like a salt shake then it is bad. Newer relays have no way of telling other than you can visably see the relay is burned and can smell it as well. If your compressor is hot as the devil then the relay is stuck in start and both windings are going at once. This will cause the overload to trip and kill the compressor till it cools back down. otherwise the compressor will cool the box albeit intermittantly. If the contacts are disentergraded within the relay the compressor will not run.
go to the back of the fridge see if it has a white relay on the compressor that's the piece that plugs onto the compressor if it does un plug the unit take it off and shake it if it rattles and little black stuff falls out of it replace it with a three in one relay from an appliance repair parts store just follow the instructions on the part its easy don't worry about water in the ice maker it will fill when it starts cooling if it doesn't have the relay try turning it off for 24 hours to give the oil time to run back down to the compressor and advise me further
Is it cooling at all? Do you hear the compressor start or just a buzz for a few seconds?
This sounds like a compressor or compressor start relay failure.
Unplug the machine.
Access the compressor and remove the relay that is plugged to the side of it. Shake it and see if it sounds like there are a lot of loose pieces in it. Inspect it for burned spots. If you find either one of these, it is bad. If it doesn't rattle or appear burned then the compressor is probably bad.
Even if it seems ok, I would try a new one on it anyway. They aren't usually very expensive.
If the relay is not the problem, check your owners manual for the warranty info. The compressor may still be covered by warranty even if the rest of the unit is out of warranty.
