Duo therm ac not working

I have a 2005 coachmen captiva. I turned on the AC for the first time this season and this is what happened. The ac unit fired up like everything was O.K. but no fan turned on. After a minute or so the ac unit vibrated and shut off. Is there a seperate fuse somewhere for the fan?

If your Rv is wired the same as a Mirada it will still be on a 110volt transformer and i am guessing that you would have 110volt circuit breakers i imagine you would have checked those ?.Did you have your thermostat (temperature control) set lower than air temperature?You may be able to try the fans only by putting the control unit on manual and trying High and low fans.I have had a time when i turned my unit on and nothing happened and then an hour later it worked!! Also who converted your RV if it was carcon the electrical work is disgraceful as is the rest of there work.

Make sure the fan blade turns freely when off. Not bound up anywhere. Check or replace the fan motor capacitor.

Have a duo therm ac and the low ac and low fan not work -


Thermostat on wall, or manual controls at AC? Did it work for you on low before now? Reason I ask, is that normally they are only a 2 speed fan ( low and high) so if it's a wall thermostat and has been changed from original, perhaps it the way the thermostat is wired.

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.

Duo Therm AC won't cut off with thermostat


Hi, sounds to me like the thermostat is at fault.You have done nothing wrong to it but cover it up. The t-stat is what controls it, turns it on and off. The only other thing that would keep it on all the time would be that the thermostat wiring could be touching together from the stat up to the unit. You might check that before replacing stat. I have seen this many times.You can start the unit and go up top and disconnect the stat wire and it should stop the unit.Then its either the wire or stat.Let me know what you find,
Sincerely,Shastalaker7

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


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.

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.
