Hi,

i have the whirlpool refrigerator compressor model 8201555, this is brand new compressor, i want to know if the new compressors come with pre-charged refrigerant or not. the instruction sheet doesn't say anything about it. i removed the black rubber plug from the suction pipe, i heard a hissing sound. and i put it back immediately. thanks, your help is greatly appreciated.

I though I had a compressor that was locked up as well and couldn't believe it on a 3 year old refrigerator. It actually turned out to be the relay, but it wasn't necessarily that the relay was bad, but instead, poorly designed. The factory relays only have a "run" capacitor which works great on a brand new compressor, but put a few years and a little bit of cat hair on it, an the relay is no longer strong enough to start it. You can't use another factory relay because it will not solve the problem. Instead use an after market universal, heavy-duty relay that has both a run capacitor and a start capacitor, and the problem may go away which it did for me.

Hope this helps.
