Incoming voltage fluctuations appear to be your problem. 94 volts is not enough to run that AC without causing problems. 114 volts will be o.k.
Remember, when voltage goes down, your amperage draw goes up. That will trip the breaker, and eventually weaken it if it happens too often and it will start tripping at even lower amperage's. Low voltage also will shorten the life of the components. So basically when running at 115 volts, the circuit will handle it, but when you get as low as 94 volts, it will trip that breaker due to higher amperage draw.

I have duo therm rooftop Ac unit, was working fine and just went out. Seems like it is not getting power, I checked breaker and fuses. Still not working. What do i do next ?


First of all are you plugged in at a rv park or home? Had ours do that as well, found the electrical source in rv park was defective. Caused our AC unit to cut in and out then wouldn't run at all. Moved to a new location and the ac was fine.

Rockwood trailer manual


Contact the manufacturer of the coach for their owner's manual. However, each appliance will have a separate owner's manual form its perspective manufacturer, i.e., Water Heater = Suburban, A/C = Dometic, Refrigerator = Norcold, etc.. There will not be a diagram of electrical or plumbing as a majority of the RV manufacturers do not publish that information. The only thing that I can think of that would cause the TV to reset when the Air Conditioner comes on is if the AC is remote controlled you may have a frequency conflict. It is not typical for the AC to share an electrical circuit with the TV but if that is the case here then the TV may be getting shut down because the AC is drawing too many amps on startup for the TV to continue to function. Turn the breaker off to the AC and see if the TV shuts down also. If it does then you will need to get the issue corrected.

Duo therm mod. 57915 air conditioner seems to work good , runs for 4-5 minutes then kicks breaker , was kicking 30 amp breaker at camp ground , i've been working on connections to make sure its...


Unit may pull as much as 17-18amps when compressor starts up, but level out to 12-15 amps when up and running. Keeping in mind that is all relative to proper 120v incoming voltage, heavy enough wire to run the application etc. If your AC unit needs cleaning , it may draw an extra amp or 2 . With that said, when your at the park, first thing I'd question is their incoming voltage to RV, and try running fridge etc and anything else on propane if possible. The AC alone should not cause 30amp at source breaker to trip, before 15 0r 20 amp breaker in RV that is connected to AC trips. If it doesn't trip your breaker at home, and all is connected same at park, then I certainly would suspect bad breaker or voltage/wiring at park is the cause. P.S. I noticed you said you have 12 gauge wire (rated at 20 amps) connected to a 20amp breaker at panel, but RV is plugged in to a 15amp receptacle, I will assume with a 15 amp adapter from 30 amp plug. Do you see any hazard regarding 15 amp rating on receptacle? ( just a little advice.)

My unit was working fine until 3 days ago when the breaker tripped, I reset the breaker and worked fine for a day then tripped again when it tripped both the ac breaker andthe main in the trailer as well...


High amp draw can be caused by a few different things, so first check that incoming voltage to trailer is sufficient. (115 volts) Not unusual for some parks to install more hydro hook-ups on a feed line, and when all are up and running, your incoming voltage could be decreased. If your o.k. that way, then I'd start looking at the compressor circuit of your ac, in particular, the compressor start-up capacitor. The capacitor basically stores electricity and boosts it to higher voltage for compressor and fan start-ups to reduce current draw that will trip the breaker. Please have a knowledgeable electrician, or RV tech check this for you, as a capacitor can give a real good high voltage (possible fatal) shock, even when power is off to unit. I also suspect that the start relay has shorted (welded) itself due to high amp draw situation, and that is reason it comes on by itself.

Rooftop rv air conditioner doesn't work - what can I check myself without taking the rv to a repair place? will any air conditioner repair place do repairs or do I need to use an rv place?


I'm assuming when you say 'doesn't work' you mean 'nothing comes on,' i.e. the fan or the compressor.

If that's the case I would check for the AC breaker to see if it's tripped. Usually a 'tripped' breaker will look half on and half off, but sometimes it will be completely in the off positiion. Either way - it's usually because of a malfunction of the AC unit, so if that's the problem I would moniter it closely to see if it trips again. If it trips again in the immediate future I would then want to investigate the AC unit for the cause.

Also, some RV's have fuses in the AC circuit - so you could check and see if you have any fuses labled AC or AC control voltage. If so - you can usually - tell by looking whether they are bad or not. If that's not possible try replacing your 'AC labled fuse' with a new one of the same size.

I would also check your power supply (where the power cord to your RV plugs into) to make sure it is providing the proper voltage to your RV. Note: They also have breakers out on the box that you can reset. If they (breakers) appear ok - and you are at a RV park you could have the Park personel - check and to be sure the proper voltage is availible to your RV.

good luck!

My duo therm air conditioner works fine in the moning


If the unit has been serviced recently and they added refrigerant to it, then it's possible that they overcharged it causing it to have high head pressure which will increase the amp draw enough on a hot day to trip the breaker.If the unit hasn't been serviced, you might won't to check the condenser coil to see if it's dirty, if its not dirty then check the voltage to the unit, if you're in an RV park when everybody there is running there ACs the voltage may be to low for your unit to run. What fan speed are you running on you may need to run it on high speed during the day.

Coleman (RVP) 7000 AC unit compressor problem


I had a problem with my coleman mach 3 AC, we were at an RV park up at lake shasta CA and the fan would stay on but the compressor would come on for a few seconds and then trip off. It was the motor overload relay on the compressor that was tripping. the RV park was old and apparently the wiring to the panelboard at the RV park was too small, when you are drawing a lot of current there was too much voltage drop across their line, to make up for this the motor tries to draw more current and heats up the motor overload and it trips off. I solved this problem by buying an autoformer from Camping World, it senses a voltage drop and automatically boosts the voltage.

I am now having a seperate problem, the compressor is either locked up or has too much back pressure and trips off the service breaker when trying to start. The only solution I can see with my current problem is to replace the entire unit.

Circuit Breaker and Dometic Rooftop RV Air


Its the watts you plug in too like ither 30 watts vs 50 watts. 30 watts will cause your wires to get hot in the unit. just pull down your breaker box and look at those white ground wires.
