Question about Heating & Cooling

Duo Therm AC/Heating not working at all after tripped breaker.

I have a Duo Therm AC/Heating unit that came with the RV. About 12 yrs old. The RV is parked at a ranch and the breakers were tripped (main and ac) I turned them back on and every thing works but the ac unit. I cannot even get the fan to blow. I have looked everywhere for another breaker and did not have a volt meter with me. Going back out this weekend. Any ideas would be helpful.

I had to get on the roof of mine, remove the cover and manually spin the fan. Add a little oil to the shaft where it goes thru the bearing. All of this is done on the roof side. Mine required this procedure every spring. Duotherm realizes they had a problem and have since corrected it but they don't deal with all of their customers that had the original problem.

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.)

AC runs for 5 minutes and then circuit breaker


What else do you have running on hydro while AC is running? Such as coffee maker, microwave, water heater, fridge. That 30 amp breaker is your main breaker I assume, or breaker on pole your plugged in to. Keep in mind your AC will normally draw approx. 15-17+ amps momentarily when compressor kicks in to cool, then drop back to 12-15 amps when running normal. If your AC is drawing too much current, then you would only normally trip 20 amp breaker for AC in your panel. Try switching other appliances to gas operation while running AC, such as water heater, and fridge. Make sure incoming voltage is up to specs as well . (115-120 volts)
If water heater takes 5-8 amps, and fridge takes same when they are calling for power, you'll be close or over the 20amp mark when you consider your on board converter etc. as well. That only leaves approx 10 amps for AC that requires approx 15 amps to run, and up to 20amps when compressor kicks in. If you switch all those other items over to propane, and it still happens, then a current draw test should be done on AC unit to see if perhaps a capacitor is faulty, or possible compressor faulty.

I have a 2005 Pilgram 27 foot 5th wheel. My Duo Therm AC unit makes a ticking sound from the ac unit itself when it's not running. Shutting off the Duo Therm analog thermostat does not stop the ticking...


It's obviously on the 12voltDC circuit of the AC unit. Sounds like thermostat, or a relay in control box is faulty or bad connection. If you remove cover on ceiling assy., you should be able to hear it in the control box. There should be a model number on the ceiling assy., get back to me with that number and I can better pinpoint which relay. Also, try moving all thermostat buttons and temperature controls back and forth quickly to see if it may clean off a dirty circuit in thermostat as well. Make sure your AC hydro breaker is off when working with ceiling assy. just to be safe.

AC Kicking OFF Breaker


Sounds like you have a problem with your compressor. If the beaker trips the second the compressor tries to come on hen it is shorted. If it takes a couple of seconds, then your compressor is locked up.
