I was given a Haier mini-fridge that although never used before will not start up the compressor.  There is a faint hum when plugged in until the external thermal cutout clicks off.  I used some other online resources to verify that the compressor resistances are reasonable (not open or shorted to each other or to ground) and that the wires are connected to the proper pins.  It has a solid-state relay for starting which seems fine and I have bypassed the relay by putting power to both the start and run windings simultaneously without any luck.  I have tried thumping vigorously on the compressor can with a rubber mallet while applying power but the compressor remains stuck.  One online post suggested applying 220 volts across the compressor momentarily to try to kick-start it.  Has anyone done this?  Any other ideas for getting the compressor to start or is this the end?  Thanks!

Rob

I don't recommend 220V...you could try a hard start HS410 ...it may get you going for a while. But to be honest...your peein up a rope.

Thanks for the reply.  As I mentioned, this is a never-used unit and I feel that if I got it to spin once it would be fine after that but who knows?

Well, I didn't have much to lose so I wired the compressor up to 220 volts with one wire to the common pin and the other to the start and run pins in parallel and gave it a few short jolts or 1 or 2 seconds.  Bottom line: no change so I guess I will have to give up.  It was worth a try!

I know Im a little late, but I thought I might offer some of my personal experiences in dealing with "stuck" compressors.

Sometimes....a piece of debris or metal shard will get in the valve and seize it up. What I normally do first is use a 3-n-1 hard start and see if that starts it up. Sometimes the inline capacitor on the 3-n-1 will give it enough torque to spin it. If that doesnt work..theres one last thing you can try......

You can reverse the start and run wires on the 3-n-1 to the compressor and make it (hopefully) run the opposite direction. But ONLY LET IT RUN FOR A SECOND OR 2!! If you let it run longer than that, you could cause the compressor to seriously get jacked up...or worse. If it works and runs the opposite direction, stop it and rewire it back to the normal direction, and hopefully all goes well.

If that doesn't work, then Im sorry, but the compressor has seen its last days and it needs to be replaced. On those small little dorm fridges..its not economical to r&r the compressor. So, I'd suggest buying a new one over replacing the compressor.

I hope this has helped you to some degree.

:cheers:
