Sounds like starter on a/c is going out you need to replace it as it starts the fan and compressor as well good luck (thats assuming toutside means outside)

I have a Goodman CPLE30-1A outside unit and the fan stop spinning. The fan stop spinning so I turn off the main power to the unit and I can spin the fan with the power turn off so I'm not sure if its...


Hello
There are a few things here that could be wrong.
1 Fan motor start capacitor is bad.Silver battery looking device on side of fan.Remove and replace with a new one.

2 Contactor for fan motor is pitted or burnt .If this is the case you will need a new contactor.

3 Fan motor is bad.Check top two before assuming this.
Check all fuses and circut breakers also.

I have a new lg window air conditioner that is buzzing loudly when the compressor turns on. as soon as the compressor shuts off it stops buzzing. the buzzing noise also sounds like a playing card attached...


sounds as though the contactor is not pulling in tightly. but it also spunds as though the fan or fans might be hitting some thing . check them out shut the unit down and spin the fans and see if you hear something. if not then it could well be a contator .. But as I think a bit more could be lose fan, or compressor is not setting on it isloator bushings .

Our window AC/heat unit fan only buzzes when turned on- no matter whether you turn on fan only or heat or cool mode.


so the fan does not spin and blow air? it could be a stick broken fan try free spinning it make sure its turned of. if fan spins freely its probably your start capacitor which is not to expensive.

Unit in roof, switch on and it hums and throws the safety switch s/n 26641/12/2, thanks


Turn power off to unit first. Then Try going up on roof, and with a stick or similar, through vent slots, spin fan blade a few times, and then try to start again. Seen quite a few stuck in dead spot at motor, and this will sometimes get it off the dead spot if fan(motor) hasn't been run in a while. If it has been running, and just recently started doing this, Capacitor is probably gone but need to be careful working with it, so get back to me if spinning fan blade didn't do it. Would be helpful to have model and make of unit.

Have a Ruud Achiever Model number UAKA-037JAZ that won't run since yesterday. When the air kicks on it simply makes a buzzing noise and the fan doesn't spin. Can anyone help?


try spinning by hand when the unit make the buzzing sound. to see if the capacitor is bad. If the fan runs replace the cap. If not motor probably is bad. See if it spins freely. this is a good starting place. need to check if the buzzing is the contactor and there is no power to the condensor. The contactor will buzz even though the main breaker is off or tripped

Air Conditioner Compressor Fan Quit


Check the start capacitor. You may be able to see visual deformaty, otherwise, use a meter. The buzzing is most likely the contactors closing which uses a seperate 24v supply..

Ac fan not turning on I can ''stick start it'' but which direction?


The condensor fan should be sucking air from the top and blowing it through the coils, probably a counter clockwise direction. The buzzing/humming sound is confusing to me. A humming sound sounds like a motor that can not turn over to start. A starting capacity would be needed. Just because you changed it out last year does not mean it is good. A buzzing sound sounds like a contactor problem. Contactors buzz and after a while, they will fail. In any case, you can "stick start" the condensor fan PROVIDED you are sure the ac compressor is working (this is for a short and temporary use). Also, you may have a high load duty capacitor that assists in the unit running. This will affect your condensor fan operation if it is not good. Unless you know all the components and operations of ac electrical, I would highly recommend calling out a professional.

Carrier AC 38CKC019 may have overheated. The fan unit buzzes but does not turn.


Hey there, ok, now if the fan is spinning and the compressor is buzzing, the compressor is locked up and needs to be replaced. If neither is running and the buzzing is coming from the control panel on the unit, it could be the contactor. Also there is a chance that the fan motor burned up, causing the compressor to fail so the fan would be off but the compressor is buzzing and locked up. If nothing is running also check the circuit breaker it could just be he conactor you are hearing. At that point you need to figure out why the breaker tripped. Let me know what you find out
