Question about Dometic Rooftop RV Air Conditioner
We have a Coleman 7300 rooftop ac unit. When the ac is switched on the compressor and fan both start working. After a few minutes the fan stops but compressor continues to run about 30-40 sec and shuts off as well. We can manually restart it after 5 min. Same thing happens again. Help!!! Thank you!
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.
