Blower won't run


usually a "humming motor" indicates either a bad capacitor or a defective motor. With the power off try to spin the blower wheel...it should spin freely. If it is tight or wont spin and there are no obstructions stopping it (like an air filter sucked into blower or other debris) then the motor most likely is seized. If the blower wheel spins free then you may have a bad capacitor. Keep in mind, just because the blower spins easy doesn't mean the motor is good. I have had motors that are defective that dont seize up but most of the time the blower wheel will not spin free if the motor fails.

POWER TURNS ON AT THE CONDENSER MOTOR, BUT IT WON'T START RUNNING UNLESS I START SPINNING THE BLADE ON THE MOTOR WITH A SCREW DRIVER.


Hi,
If it spins freely when it is not powered then the start capacitor has gone bad and replacing that will fix the problem...
If it does not spin freely and the bearings need oil then check out this tip on how to oil the bearings in the motor...

My fan inside run only 5second the ciruits board been change out speed taps move to another tap it run through a cycle then when it come back it only run 5 second i need help ?


Shut the power off to the unit, spin the blower wheel to see if it spins freely. If it doesn't spin freely, (there appears to be a little drag when you spin it),the bearings are bad, if it does spin freely, then try moving the motor shaft from side to side if there’s any play in the shaft side to side then the bearings are worn and motor needs replaced. Then, check the capacitor, if it’s bulging even slightly, the capacitor is bad and needs replaced. Most of the time people replace the capacitor if motor seems ok. If capacitor is ok, turn power on to see if the motor is getting the proper voltage, if it is and not trying to run, then the windings are probably open, the motor's bad and needs replaced.

After about 5 minutes the unit stops working. No sound or even a fan noise. I just cleaned the filter to see if that helps, but it didn't.


Is the fan running and stopping before the unit completely quits?
If the fan quits the compressor won't run very long.
I would start with the fan motor or capacitor.

Check your filter, indoor coil and blower wheel to see if they are dirty, if they are, they need to be cleaned, if not, then you are probably low on refrigerant or Blower not running at full speed.

The blower on our unit works intermitently, so the AC is only cooling part of the time.

Unit turns on but it does not blow out any cooled air or any air at all. you can see that the drum inside that usually turns is not turning.
