Start with the fan motor capacitor, check it . usually 5, 7.5 or 10 microfareds.check it with a meter on the uf scale, or label wires pull it and take to electric motor shop and they can check it. if cap is good then trace wires from motor to sources of power and see if you have 230 volts to motor . if you do then motors shot. label all wires and note exactly where the fan blade is located in relation to the grill guard. sand motor shaft smooth. oil loosen bolts on blade hub and gently remove. take old motor to motor shop and buy exact replacement motor. or have motor shop man show you where to place wires. usually black and white to power, brown and brown with white stripe to the capacitor. some motors wired up with three wires. see side of motor or directions in box or ask motor man to explain. resecure new motor exactly as removed , reinstall hub and blade. if you think blade is to rusted to get off or you mess it up just take it to the motor shop. he sells blades to! just be sure you have good clearance when you get done, cap off or tape off any unused leads. i usually use little bits if stat wire to secure wires up and out of the way of the fan blade if needed. they last longer than plasties and are not effected by the sun etc. check rotation of blade. cupped or curved side into the wind . check amps on new motor. should pull less than rated . a 2.9 may pull 2.1 etc. a new motor always deserves and usually uses a different size capacitor than an old one. they are cheap anyway and not worth skipping and having a redo. good luck........

Outside unit will only run for a short amount of time with A/C before the fan stops turning and starts humming, squealing/screeching and the top of the outside unit gets hot.


The bearings are bad in the motor and after the fan runs enough it eventually gets hot, making the bearing screech and the fan locks up. Need to replace motor again. See if it has a warranty. The reason it gets hot is because the fan is what removes the heat from the coil and if the fan isn't running there is nothing to cool it off so to speak.

Is the heat pump cooling itself down? It is a combination heat pump/air conditioner wall unit.


If a unit is in heating mode the outdoor unit is in cooling mode (outside always does opposite of indoor) after a while if there is a build up of ice on outdoor coil unit stops and puts hot gas through outdoor coil to clear it. The indoor fan stops to avoid and heat loss in area served buy unit once this has been done and indoor unit coil is hot again fan will start. This is the correct operation of the unit to save against bust could and reduced efficiency

Why is my Intertherm P681S unit getting hot and the fan is is stopping?


Is the outside running? Is the outside fan running? Probably what is happening the fan outside quits running and the compressor gets hot and goes into thermal overload. need to check to make sure the outside fan is running.

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.

External fan stops operating in hot temperatures


Replace the motor on the outside fan, It should run all the time.
