The compressor is not starting either because:
1. The compressor has gone bad
2. The system is low or out of refridgerant. There may be a slow leak, when there is no refridgerant in the system the compressor will not start.

Fix:
Re-charge the system with appropriate refridgerant, if the system has a charge already or holds a charge when you charge it then the compressor should start.
If not the compressor could be bad, sometimes you can get a hard start kit instead of replacing compressor. If the system does not hold a charge then you have to find and repair the leak before anything else...

Good luck. Please give good rating, it meens a lot to me....Feel free to contact me again...

You probably are low on refrigerant. Since it holds R-22, you will need to have it serviced. The good news is that it has service ports and that it will not take much freon to charge it. The bad news is, you probably have a small leak, and will need to have it repaired before you add the refrigerant charge.

You have to try resetting the system. First turn the breaker off for the condenser and wait about 20 seconds After you turn it back on the system should reset. If you need any other assistance check us out online at Boca AC Service we are always happy to lend a helping hand

See if you can reposition the thermister on the facing of the evaporator coils. That could be it or the thermister might be bad. They don't use copper/mercury sensing bulbs these days. They use these cheap thermisters.

Compressor will not stay on.


very good possibility that it is low on freon. If indoor unit is blowing ambient air, not cooling is happening. If this is the case and you are sure the compressor is running and then shutting off, the compressor could be overheating and the internal overload is taking out the compressor. If outdoor fan runs and compressor runs, probably cause. If capacitor is bad, unit would most likely not run that long. While unit is running, feel the large line at the condensing unit. If it is cold, and stays cold, could be something else going on. If stays warm, most likely low on freon.

Is the system full? Jeeps have a long history of bad evaporators. Even if the system was serviced, you could have lost the freon overnight. Compressor cycling can be because of not enough freon also.

Will not cool properly.


You have either a faulty thermostat, dirty condenser and evaporator or a faulty run capacitor. Need to service soon before the compressor is damaged. Sea Breeze
