No power to thermostate on Duo Therm 15000

I have a duo therm 15000 btu on my Airstream. From one day to the next the thermostate stopped working. I replaced the thermostate and it still won't come on and turn the ac on. I checked and I have power running to the a/c . It's just not getting thru to the thermostate. Any ideas ? 
Thanks,
David

    Thanks for the feedback. The fuse is not blown, but I'll need to check if it has voltage going to it.

Not being smart about this suggestion. Don't buy an RV or Motorhome unless the full set of factory repair and diagnostic manuals are included. My friend is having fits now because the company techs can even figure out what is wrong with his AC.

Look for a small fuse somewhere in the control panel. Usually a blade type (car) fuse 3 to 5 amp. Chack to see if its blown. If you have no fuse, or its NOT blown. Check to see if you have voltage comming out of, and going into the transformer.

Thsi is where you would START to diagnose the problem. Check this and we can go further.

Have a Duo Therm 59516.531 15000 BTU blower motor does not run checked cap 5mf ok tried direct power still nothing any thought. thanks


if you tried direct power and still nothing then your fan needs to be replaced . there should be a a/c supply store near you . get the model - serial number on the fan or the unit itself to get the right fan for your unit . hope that helped

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.
