Air Conditioner Breaker Tripping

Each time we use our Coleman a/c on our 2007 Sportsman RV, it trips the breaker. When we turn the a/c on and leave when we come back we find the breaker tripped and the RV warm, not cool. This has happened at 3 different locations, so it cannot be a low voltage problem. We now have the RV in for repair. They indicate the breaker has not tripped when running the a/c. They cannot find the problem. Please help!!!!!

This is a tough one to diagnose without seeing the panel. It's the main breaker or just the a/c breaker? The easiest diagnosis is to put an amprobe on the black wire coming off the a/c breaker (Harbor Freight about $12.) to see how much current it's drawing. It should be less than the rating of the breaker (shown on the end of the handle). Make sure the thermostat is all the way down so the compressor is running.This is a likely solution because a high current draw can be caused by anything from leaves laying in the bottom of the shroud to a compressor starting to go bad. If that amperage is lower than the breaker rating and it trip's it's probably just a bad breaker.Another cheap fix. I would have to assume the rv dealer tried this so we can move on but it is the best starting point. Loose wires anywhere in that panel can also transfer heat through the buss bars. Unplug your power source and tighten all connections. The panel won't get warm until its been on a while and heat is what causes the breakers to trip. Again I assume the dealer would have tried that but I'm trying to cover all options. The last thing I can come up with is maybe the RV dealer isn't putting the cover back on the panel while troubleshooting which stops it from building up heat. Without the additional heat build-up the breaker won't trip. The inside of the breaker is two metals sandwiched together designed to bend when they get warm. When they get warm enough (caused by the rated current flowing through the breaker) they bend enough to push a button to trip the breaker handle. Try these out and let me know if it works.

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).

Sounds like possible fan capacitor failure. If your not familiar with capacitors, please find someone who is, as they can give a fatal electrical jolt if not handled properly.

Rooftop RV Air Conditioner: replaced capacitor on dometic 59516-531 steal trip...


You need to borrow a clamp on style amp gauge, and check amp draw on black wire in box where hydro wires connect. (PLEASE, be careful, and if not experienced in this type of test, don't try it, due to likelihood of getting a shock. ) If it's the compressor kicking in that's causing the breaker to trip, and capacitor is good, then it's usually a problem with either low incoming (supply) 110-120 AC voltage, which will cause high amperage draw, or compressor on it's way out causing high amp draw. If it's only drawing 15-18 amps, and your tripping a 20 amp breaker, then breaker is getting weak.

Portable generator pops breaker when temp is over 75 degrees


I take it you have RV plugged into generator. Hopefully direct with no extension cords. Are you using a 30 to 15 amp adapter to plug into generator? What is the rating of the breaker on the generator that keeps tripping, suspect it's only 15 amp?

A/c is drawing 20 amps and keeps tripping breaker after running


If the fan is running and the compressor is getting hot and tripping off you may have a failed capacitor.

Rv electrical question


By the main breaker in the camper, do you mean the main 24 or 12 volt breaker, or the incoming 120vac breaker? Is it tripping the breaker in the camper, or the house? If it is tripping the breaker inside, i would look for maybe water damage, rusty components, maybe have an electrician come look at it, not worth going out away from home, and that problem ruining your vacation! Does this unit have a generator set? Try disconnecting the generator too. Hope that helps!

Air conditioner will trip breaker when trying to cycle back on


The compressor motor , once warm is grounding out due to wear and is going bad.Have the compressor replace while it is still clean is cheeper and easier that doing it after a burn out,which  will eventually happen,if the compressor is tripping the brreaker as I suspect..

Coleman RV Rooftop Air conditioner


If the compressor is tripping the breaker, then its 1 of 2 things. First clean the coils and change the air filter. If the coils are dirty and/or the filter is clogged, it will make the compressor overload and the high amp draw will make the breaker trip. If this doesn't solve the problem, you need to check the compressor itself. remove the connections at the compressor, leaving only 3 posts on it. You will need a meter to check for continuity to all 3. They should all have continuity to each other. While there check the wires. Sometimes a burnt wire will come off and arc on something causing the breaker to trip, if you are lucky.
