I was told that when the unit fires on, it surges around 3500 watts, and then runs at around 1500 watts. That is why I had to buy a 5500 watt generator, which is too loud to even run in most places. Most extension cords wont be able to hold that much power, so if your not using some sort of generator, make sure you dont try to use a 120v extension cord (like the orange ones)

I have a coleman model 8333A8664 a/c unit on a fleetwood camp trailer and was wondering what watt generator would be needed to run it properly?


Because it won't be powering just your AC, I would recommend 5000W. It's that big amp draw when compressor kicks in that will pull it way down, if not strong enough. Take for example the fact that a dedicated 20 amp breaker and cable are the norm for RV's to use for AC now. Double check also that the generator your purchasing will take a momentary surge draw of up to 20+ amps without tripping breaker on generator. I say 20+ because once RV is plugged in or wired to generator, it will be powering any other hydro operated appliances, lights, converter etc that the trailer has on board. I bought a cheapie rated at 4000W, and 3000 running watts, but it kicks out the breaker just trying to start my portable air compressor, rated at 15 amps.

I have a 3000 watt generator, will this run the 15000btu air conditioner


It should, but what have you got for plug ins on generator? 30 amp, or 15? I believe the rough estimate is 100 watts , equals roughly 1 amp.

We have a Coleman 7300 rooftop ac unit. When the


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.
