The Ways An Air Conditioner Compressor Can Fail, and What To Do About It

Executive Summary About Air Conditioner Compressor By Jim Locker

The compressor can fail in only a handful of different ways. It can fail open, fail shorted, experience a bearing failure, or a piston failure (throw a rod), or experience a valve failure. When a compressor fails open, a wire inside the compressor breaks. If the compressor fails open, and following the steps here does not fix it, then the system may be a good candidate for a new compressor.

Testing for a failed open compressor is easy. If any of the terminal to terminal connections is a very high impedance, you have a failed open compressor. When a compressor fails short, what happens is that insulation on the wires has worn off or burned off or broken inside the compressor. Bad bearings can cause a failed short. Every time the short occurs, the compressor torque drops sharply, the compressor may shudder a bit visibly as a result, and this shudder shakes the winding enough to separate the short.

Then the compressor stops. With a failed short, just give up. Less commonly, a compressor will have a bearing failure, piston failure or a valve failure. 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.

Rarely, the compressor will experience a valve failure. Again, a system with a compressor that has had a valve failure is a good candidate for a new compressor.

I once saw a system that had a locked compressor due to liquid lock. This overloads the compressor, but gives some extra torque for a short time and is often enough to make that compressor run again.

Air Conditioning Manufacturers – Air Conditioner Compressor

Executive Summary About Air Conditioner Compressor By Ricky Lim

Each air conditioner brand is different therefore if there is something wrong with it, it is best to contact the air conditioning manufacturer for repairs.

One of the most common problems is that the air conditioning compressor might get filled with excess water and dust.

Sometimes, the air conditioner filters are dirty and not cleaned properly which could cause an air conditioning compressor total failure. Some times the failure of the system or any part of it, may lead to the stoppage or improper functioning of producing cool air in the environment.

For thorough servicing, it would be best to buy a service contract either with the manufacturer or service companies.
