A Duo-Therm 13.5BTU Brisk Air unit will pull 14 - 16 amps on average in High/Cool mode. Depending on the ambient temperature. Since the unit is 120VAC, then we know that the unit is going to need at least 1920Watts to run. There are other things in the unit that will affect the generator as well. TV's, Microwave and Converter all pull amperage on the generator. It is safe to say that if you are using a 4000Watt Generator, then you will be fine. If it is just for the AC and nothing else, then a 2500Watt generator is more than sufficient.

Thanks,

Jeff

Your A/C unit is 13500BTU/hr which converts to basically 4 Kw/hr. When running a A/C unit from a gen you need to over size the gen to handle start up of the compressor. Go about 50% higher on your gen wattage. About a 6Kw-7.5 Kw will work for you.

I have a duo therm model 630035.321. What is the best replacement unit?


There isn't one. Every a/c unit is a piece of junk. Just like your t.v., fridge, and microwave. Buy cheap, replace when it breaks down. It's all luck, so Good Luck!! Best Wishes!!

Dometer 3105457. how big of generator for the air


If it is a normal AC for RV then I would suggest something over 4000 watts, the AC's have a very high start amps.

You would really need to know how many amps the unit draws or is rated to draw when looking for a generator. Too small of a generator and it won't work, plus you could damage the generator and the AC unit. I would call an RV store and ask them as that is something simple for them to answer.

I HAVE DOMETIC DUO-THERM PENGUIN ROOF AIR CONDITIONING ON RV. THE UNIT WILL RUN WHEN PLUGGED INTO ELECTRICITY BUT WHEN GENERATOR POWERED THE AC UNIT KILLS THE GENERATOR ENGINE. WHAT COULD IT BE?


What size & type generator? On start up the AC unit can draw as much as 17-18 amps in some cases, and if your generator is not designed for a quick draw like that it will die.

How do I install a blower motor in a duo therm model 57915.622? What tools will I need?


ITS NOT EASY. YOU NEED A LONG SET OF ALLENS TO LOOSEN BLOWER WHEELS. THIS IS A  DUEL SHAFT MOTOR , BACK COIL NEEDS TO BE PULLED AWAY FROM MOUNT WITHOUT BENDING COPPER. MOTOR BOLTS 3 OF THEM HAVE TO BE REMOVED AND WHEN BOTH BLOWERS ARE REMOVED AND WIRES REMOVED THEN IT CAN BE REMOVED . THE PROBLEM IS THAT THE NEW MOTOR IF IT IS NOT FROM DUO THERM YOU WILL HAVE TO CUT SHAFT TO RIGHT SIZE AND WIRES MAY NOT BE SAME COLOR. IF IT IS SAME MOTOR FROM DUO THERM YOU CAN CUT WIRES AT OLD MOTOR AND WIRE NUT THEM COLOR BY COLOR.

Penguin Duo therm AC bogs


Try replacing the wall thermostat with an electronic unit. It sounds like it is short cycling. If there is not at least 5 min delay before trying to restart the compressor this is what happens. Most electronic thermostats have a delay feature built in to solve this problem.
