Less commonly, a compressor will have a bearing failure, piston failure or a valve failure. These mechanical failures usually just signal wear out but could signal abuse (low lubricant levels, thermal limiter removed so compressor overheats, chronic low freon condition due to un-repaired leaks). More rarely, they can signal another failure in the system such as a reversing valve problem or an expansion valve problem that winds up letting liquid freon get into the suction side of the compressor.

If a bearing fails, usually you will know because the compressor will sound like a motor with a bad bearing, or it will lock up and refuse to run. In the worst case, the rotor will wobble, the windings will rub on the stator, and you will wind up with a failed short.

If the compressor locks up mechanically and fails to run, you will know because it will buzz very loudly for a few seconds and may shudder (just like any stalled motor) until the thermal limiter cuts it off. When you do your electrical checks, you will find no evidence of failed open or failed short. The acid test will show no acid. In this case, you might try a hard-start kit but if the compressor has failed mechanically the hard-start kit won’t get the compressor to start. In this case, replacing the compressor is a good plan so long as the rest of the system is not decrepit. After replacing the compressor, you must carefully analyze the performance of the entire system to determine whether the compressor problem was induced by something else.
