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

fan defective or capacitor.

the fan control is not for the fan on the top of your outdoor unit. that is for the blower, you have 2 fans. Im guessing you have a split system, 1 unit inside and 1 outside?? Does the outdoor fan continually run??

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

Dear Friend!

Due to very low ambient temp, the fan will not run. Once the pressure build up, it's automatically run for some time and again cut off. But if you keep Heat mode and still tem not raised in your room means the reversable valve not working and hence the compressor and out side fan also will not work. Keep "Heat" mode and temp setting +29 to get better heat. Hope is it helpful?

Some fan in outdoor works only after pressure build up.

either the fan has went out or the capisitor for the fan is bad and needs to be replaced.if you have run the outside unit very long without the fan turning you might be replacing the compressor as well as the fan or capisitor.if the fan isnt pulling air through the cond coil outside,the compressor gets very hot very fast,and it locks down(burns up). get it looked at asap before it cost more because of other broken parts caused by the fan not working.

If the inside fan motor is running OK you are low on refrigerant. If the inside fan motor is not running, repair the inside fan motor. Could also possibly be dirty inside coils.

The buzzing noise is your contactor drawing in from your thermostat. The fan part of your unit is on a different circuit from your outside A\C unit. Your thermostat is the conductor of the orchestra tying ths units together. It may well be that your A\C circuit breaker has tripped, if it has there is a reason for it's tripping. Resetting the breaker by turning it off then on may get your unit running, but a technician needs to ascertain why it tripped. Or it could be a bad contact switch inside the outside unit not letting enough electricity through the switch. More than likely the first issue. Good Luck

If the heating and cooling is working O.K. and maintaining the proper temperatures it is possible that your outside unit is in its off cycle. If the inside unit is running and the outside unit is not with an elevated temperature inside check the power supply to the outside unit. Most units have a disconnect located near them. Check the disconnect and make sure it is set to the on position. Listen for a hum noise at the outside unit which could indicate that the control power is being supplied to the contactor.
