Question about Dometic Rooftop RV Air Conditioner

1 Answer

My Coleman RV roof air went off and will not turn on after if restored breakers.

I have a Coleman AC on roof of travel trailer. I plugged in 110 current and then turned it on. AC ran for about 10 seconds and them cut off. I cannot restart it? I have refreshed the main RV circuit breakers.

    Thanks. I'm at work, but will check tonite. It is connected to power. It has worked before. I need to use bigger extension cord and plug into 30 amp. That may be problem. Where is a fuse in the unit? I have cover off, but have not opened inside boxes.

    I thought when you mentioned the cord size and length that you were right. I plugged a 14/3 cord into 30 amp plug, and the AC took off like new! Thanks a bunch.

Coleman mach rv ac unit tripping breaker


If it trips the circuit breaker as soon as you turn the FAN on, suspect either a bad fan motor or a failed fan motor start capacitor. If you are able to turn the fan on but the circuit breaker trips as soon as the COMPRESSOR starts, it is possible that the compressor is seized.
If, on the other hand, the unit is tripping a GFCI (Ground Fault Circuit Interrupter) breaker or GFCI utility outlet, it is possible that neutral and hot are reversed at the outlet into which the trailer is plugged (happened to me this year at an RV park).

What size circuit breaker is on the generator that is tripping? You'll need a 20amp for AC alone, then consider other things that are drawing current when RV plugged in like , converter, fridge etc that may be drawing current at same time. Make sure fridge is on propane, as well as water heater if you have electric element option on water heater. AC may only draw 12-15 amps when running if good and clean and wired properly, but will draw 17-18 amps when compressor kicks in. Perhaps generator not designed for that surge?

Drain for a colelam rv air conditioer


It is entirely possible that a five minute test would not produce any noticeable amount of water. Turn off everything in the house that is using electricity and your 20 AMP service will be sufficient to run your AC.
