Unit comes on fan does not spin

Have installer come back and inspect it if installed properly ( correct power being supplied ) possible defective unit like bad winding or bearing

Hello, try spinning the outside fan with a stick or a small object you can spin the fsn blades with, if this gets the motor running the capacitor must be replaced. If the motor does not start by manually pushing it the motor will have to be replaced.

If you have a multimeter that tests "uf" or "mfd" that is microfarads. That will test the capacitor. Turn off power to unit, touch top of cap with insulated screwdriver across terminals to discharge and remove fan and common. MARK WHICH WIRES GO WHERE. Or if no mfds on multimeter, amps×2650÷volts=mfd. Amp draw on fan wire off of cap times 2650 divided by the volts between common and fan on the cap. If cap is good it's likely the motor.

The switch that you are resetting is the manual reset high pressure switch. It is there for a reason, to tell you something is wrong. You having to start fan manually tells me that the fan run capictor is bad. Get the capictor changed. If you keep resetting the switch you could burn out the compressor, doesnt make any sense to burn up a 800.00 compressor for a 10.00 item. hope this helps.

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

Hi!!
The part you need is called STARTING CAPACITOR and it is located in the same compartment where the electrical connectors are in the outside unit. MAKE SURE THE POWER BREAKER IS OFF before opening the compartment. and before working with the capacitor, touch both terminals with a screw driver to short them out and discharge the capacitor. Don't worry this is just a preventive measure and no sparks are going to be coming out of it. Once the capacitor is discharged, take a picture of the wiring and label them before disconnecting the wires. Remove capacitor and take to an appliance parts store to get a new one.
HERE IS A PIC. OF HOW A CAPACITOR LOOKS LIKE



Good Luck!! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.

If the fan is a capacitor start, induction run motor, then it is a good chance you need a new cap. This will be a round or oval shaped can that has spade connections on the top. Depending on the unit, it may have a dual capacitor. These capacitors provide the power necessary to start the fan and the compressor. Be sure to replace with a very close match as the existing.
If the fan is a PSC (permanent split capacitor) motor, then it will have a run capacitor wired in series with the start winding, and this capacitor never comes out of the circuit, providing greater running efficiency. This capacitor can be mounted directly to the motor, or placed remotely.
Hope this helps

It sounds like the run capacitor of your condensor fan failed. When it fails, it can prevent your fan from starting unless you manually spin it to get it going, then it could run for awhile before it overheats.

Be careful.....! If it starts when you push it you can hurt yourself seriously from the spinning blade. Sounds like your motor has a bad capaictor. Turn off the power (circiut breaker). Remove the old capaictor. Find the rating on the side. Replace it with the same rated size. If the motor has been subjected to running without a good capacitor for a while you "might" also need to replace the motor.
Good luck........

If you have power to the fan and the fan won't come on, then its bad. You don't have to do another check. You will know if the capacitor is bad by turning the power on to the unit and taking a stick to start the fan. If the fan starts running after manually spinning, then the cap is bad. If not, the motor is bad.
