Remember that one of the best ways to prevent unexpected A/C problems is to have regular maintenance performed on your unit. If you cannot perform the maintenance yourself, hire a professional to do so. Spending money on maintenance now can save you from big repair bills in the future.
Some of the most common AC problems are listed below, and they may even be the reason why your air conditioning unit won t kick on. Review this information so that you know how to best troubleshoot problems with your unit. Be sure to determine whether your unit has shut down entirely or whether only a part of your unit has shut down or isn t working. Remember that it is always necessary to cut power off to your unit before inspecting it for wiring-related problems.
The AC unit does not cool rooms evenly: Inspect your unit s distribution channels. Make sure that the fan on your unit is kicking air into rooms or into your duct system.
The AC unit turns on but doesn t cool: If your unit turns on but doesn t cool, check your thermostat to be sure that it is set at the correct temperature. You should then check the condenser and evaporator for dirt and clogging. If too much dirt builds up, your unit may not turn on at all.
The condenser unit returns on and off repeatedly: Having a unit turn on and off repeatedly is extremely frustrating. In general, this problem is caused either by a dirty condenser and fan or a clogged condenser.
The condenser unit won t turn on: If your condenser unit won t turn on at all, you may have a faulty motor or the unit may not be receiving power. Examine all wiring and ensure that the unit is plugged in.

If the compressor runs but the fan does not turn then that tells me the contactor is pulling in. Therefore, the fan should be turning. 99% of the time it is a burned out motor. Do not bother with the capacitor suggestions, it will be a waste of your time. Take out the motor, go to ACR or Johnson Supply, or Baker distributing, or Century Supply, or Grainger and get a matching replacement. Always get a new capacitor with the new motor. They are only 3 dollars and good insurace for the new motor. You will probably spend a total of 65 dollars. Git er done!
ps: if the compressor does not come on either then the problem is a bad contactor or thermostat or broken 24 volt control wire to the contactor. If the freon pressure is too low because of a loss of freon then a pressure switch could be keeping the contactor locked out. In the event of no compressor and no fan running, do not start off with the fan repair. Start off with the contactor and make sure it has 24 volts on the coil and that it pulls in.

My condensor fan won t start on its own. I checked the cap and it tests normal. If I push the fan blade with a stick a little bit, it starts up perfectly. show more My condensor fan won t start on its own. I checked the cap and it tests normal. If I push the fan blade with a stick a little bit, it starts up perfectly fines and continues to work well until it cycles off or or gets turned off. Is this a clear sign that the fan motor needs replacing?
