It sounds to me like you will need to replace the start capacitor. If your fan motor doesn't have a external capacitor then you will need to replace the motor. Thank you,t

Dryer runs for three or four minutes then shuts of and willnot start for 10 minutes or longer'


Could be motor overheating and shutting off. Need to check if drum turns freely. If it does check vent hose making sure it isn't plugged causing dryer to overheat. If motor is bad it will get worse and just not start

Why does my airvent whole house fan stop working intermittently?


if fan was able to run normally after a while, you may have problem with the motor starting capacitor, this gives the fan the needed kick to spin , when your fan stops working this may mean that the capacitor have already over heated, turning it off for a while will give it chance to cool off then start up again, have the capacitor checked and replaced immediately.

It is a Bryant Legacy AC unit. Model #123RNA060-B. It has been running fine, now it has suddenly shut down. The interior fan is working, but the fan at the compressor shuts down. It will work fine for...


I had a unit do the same thing to me, everytime I would leave, it would stop working again. I had a bad fan motor that would spin fine and work for a little while, but would shut down. It was the motor windings that would overheat and shut off, as soon as they cooled, it would start back up. One way to check is to feel the top of the unit where the base of the fan mounts and see how hot it is, best to check while it's not working how it should, but try not to run it very long or you could damage the compressor. Hope this helps!

Fan doesn't come on ..compressor seems to start.


If unit hasn't been running for a while, shut power off to it, and go up on roof and take a long stick or similar, and try to feed it through air slots in cover at back and try to spin the fan enough to rotate it 3 or 4 times. Then have someone turn power back on (with stick out of there obviously) and try turning on fan mode only to see if fan will now come on. If it does, run it for a few minutes then try cool again.
Sometimes they get a dead spot from not being used for a while, and this will get it going again. If you have trouble rotating it, remove cover and spin by hand well, but make sure power is off, then try it again. If unit was running recently, have capacitor checked first, then fan. Capacitors can give off a very dangerous shock due to high voltage stored in them, so don't try it yourself if not familiar with capacitors.

Sometimes on new units it is common for the fan to not start until you give it a push. Did you happen to hear if the compressor was operating? If the unit was froze-up the Insulated Suction line would also be iced over as well. If it wasn`t it is more likely that either the compressor was not operating or it shutoff due to
high discharge pressure and can only be reset on its
own or cooling the compressor off with cold water.

Sounds like your condencer fan motor is stuck. Can you take a long rod and when the power is off to the outside unit, spin the fan blade? Maybe it will be enough to get it working again.

RV air conditioner. Compressor running, fan stops before cool


The fan motor is getting hot and going off on the internal overload in the motor.
This is caused by either a low voltage, a bad capacitor, or tight or dry bearings in the motor.
To check the bearings turn the power off to the unit, then spin the fan blade if it spins freely then the bearings are ok.
To check the capacitor you will need some kind of tester or you can buy a capacitor and replace it, that's what a lot of people do. They usually don't cost very much.
To check the voltage you will need a voltmeter and measure the volts at the unit.

Fan stops


The cooling fan for the condenser is probably running, getting hot and seizing up. Check to see if the fan is free spinning after it stops. Take a probe and try to spin it manually. If it turns freely, then it could be going bad with it's electrical windings, the internal coils that create the magnetic field that spins the rotor of the fan motor. I suspect it is seizing up, however, once a fan seizes up, it usually stays that way and won't spin even after it cools down. It could be a capacitor that is going bad and not starting the fan after it gets hot. A capacitor is a small round shaped can type with usually 2 wires hooked in series with the motor it is trying to start. That is what it does, help start the device (compressor or fan motor). Good luck.Ken from Henderson NV.
