1. Check fuses or Breaker at outside disconect box.
2. Check contactor and make sure that there is 220 - 240 Volts at entry point and at exit point(Entry point is where cables from disconect box come in - Exit point is where cables are distributed to compressor, Capacitor and fan.)
3. If there is no voltage at exit point check the coil of the contactor for 24V~ . If there is voltage at entry point and voltage at coil and no voltage at exit point ***Replace Contactor***

Unit set to heat but outside unit fan won't turn on. Outside temp is below freezing. The weird thing is that you unit is putting out heat and not set to emergency heat


If it is a heatpump, the outside unit should not turn on below 35degrees or so. Below that temperature, the unit cannot effeciently exchange heat. When the outside temperature is low, the system automatically switches over to auxillary heat which uses the same heating elements as emergency heat.

AC compressor wiil not turn on


You will have to find the contactor which is located in the outside unit. And check the voltage at the contactor, 26 v as this is the thermostat calling for the compressor to come on. You can also push in the contactor and see if the fan and compressor start. There should be an outside fuse box close to your condensing unit. Good luck

Can i run the fan on my inside unit if the outside unit is not working


You should be able to run the fan on the inside unit if the outside one isn't working. If you're worried, turn off the circuit breaker for the outside unit. If you don't know why the outside unit isn't working, check the circuit breaker at the breaker panel, check the breaker inside the box that electrically connects to the outside unit, and check the outside unit for a reset button.

A/c unit not working. Have thermistat set on 65 and temp. in house is around 85. check the breaker box for the house and it have not tripped


You must make sure that there is power to both the inside unit and outside unit. Is the room air blower blowing? If not you have either a plugged filter, iced up coil, the access door is not quite closed or there is no power to the unit. Is the outside unit fan turning? If not, you either have no call from the thermostat, the fan is broken or the unit has no power to it. I would turn off the breaker to the inside unit and switch the breaker near the outside unit to off and let them sit idle for 5 minutes. Switch both breakers back on and chect to see if the outside unit turns on. Then check the indoor unit and see if this starts blowing. Let us know what you find.

A/C quit running


This question is really to broad to answer. There are several things that could cause it to stop running. I think I would turn everything off, let it cool down for several hours and try it again. When you kick it back on, take note of what is running and what's not running. Inside fan, outside fan, compressor. If the outside unit will not run at all it could be as simple as a grasshopper caught in the contacts. If you hear the compressor running outside but no outside fan, The fan motor probably needs replaced. Please make sure that all power to the unit is TURNED OFF before removing cover plates on outside unit and before trying to remove insects from contact points. Check all wiring inside outside unit while it is open. Also check capacitors for swelling or leaking. If you don't know how to turn all the power off or open the outside unit, you need to call a professional AC technician. Hope this helps. kstfas
