The indoor fan is running . but the compressor and outdoor fan does not come on . check fuses there should be a disconnect on the outside by the unit it may have fuses. one could be blown. if the unit has a curcuit board see if any light are falshing. let me know
You probably have a bad run capacitor in your outside unit. You will need to cal a service tech to test and replace it, until then turn your system off until it is repaired. Continuing to try to run it will over heat the compressor and fan motor and cause them damage.
If the fan is not running is the compressor not running also...if neither is running the possible reasons are 1..no power to outside unit...2..bad contactor on outside unit.is this buzzing if it is this indicates no power...3 bad capacitor,do both compressor and fan humm then quit humming and hum some more...4 high pressure switch has shut unit down because fan wasnt running if compressor was running but not fan....if your unit has this there will be a manual reset button where the lines come out of unit...if compressor was running and fan was not...1 bad fan...2 bad capacitor.. if you do not have any electrical knowhow i would recommend calling a hvac tech to come and fix unit...Thanks
Make sure the outside unit is running, compressor and fan. Sometimes it is hard to hear the compressor over the fan. If the outside unit is not working check circuit breakers first. Set thermostat to call for a/c and make sure the contactor in the outside unit pulls in. If it does check capacitor for whatever is not running. If everything seems to be running fine hold your hand above the fan outside. The air coming from it should be hotter than the outdoor air. If it isn't get the refrigerant charge checked.
It sounds like your inverter is at fault. You will need an inverter tester ( most good service techs will have one ) to prove that the output to the compressor is correct. If the inverter is okay then it will be the compressor at fault with a location error or it is simply seized. A common fault that caused this was the eev remained closed (coil failure ) and caused the compressor to over heat.
If the out door fan keeps running and the compressor cycles off that would be the overload in the compressor.
What keeps the windings cool is the refrigerant back to the compressor.
For the overload to cycle it would have to be either not enough cooling back to the compressor or high amp draw, which could be the metering device (txv or orifice) or low on charge, or other things would be a bad capacitor, sometimes a bad start relay not staying open, when compressor gets up to speed or anything causing the compressor to draw high amps.
To check the refrigerant, he needs to check the superheat at the compressor it should be appoximately 12° to15°, and next time the compressor goes off if you shut the power off and feel the top of the compressor and if it's hot 130° or higher it's probably refrigerant.
