QuestionThe Clutch rotates a few degrees causing the coil wire to be pulled tight, short, and blow fuse. Compressor with clutch was replaced. same problem is reoccurring. Local air conditioning mechanics (2) "have never seen anything like this before"
Help ?
AnswerLarry,
Ok, I spoke with the other instructors at the schoolhouse, and they all say the same thing. This is virtually impossible on a good compressor. The only thing we can come up with is that maybe you happened to get the one shot in a billion of the new compressor being bad for the same reason the old was. Or maybe there was a bad line of compressors that came out, and you received one from that bunch. Because on a good compressor, with a good clutch and everything mounted the way it should be, this is impossibe.
Inside the clutch is a coil. This coil acts like a stator in a generator. It stands steady regardless of how the rotor (in this case the shaft) is spinning. For some reason yours is wanting to move. This could be a broken mount that the coil sits on. Regardless, this is a bad compressor clutch. You definately need a new one.
When you take it off, bench test it. Hook a positive wire to it, either from your battery or a power supply and ground it so your clutch is engaged. Then turn it by hand. Does it do the same thing? I am betting it will.
Sorry I couldn't be of more help, but you need to take that compressor back to where you got it and get a new one. It should be returnable, being that it never even made it into operation.
Also, get with Mitsubishi, and see if they had a series of these bad compressors that made it onto the market.
Ok, thanks for the question, and if I can be of any service in the future, please let me know.
