DuoTherm Units

Yahoo Message Number: 100872
I just tried to check out my AC on both front and rear units of my coach. Both AC units start up and get very cold but neither fan (front or rear) will come on in any mode (manual or auto). Has anyone experienced this before? I am thinking it may be my controller (thermostat). Any help is much appreciated.

Hodge, I have experienced the same thing.  Remove the A/C conver from the inside of the coach.  Give the fan a spin while the thermostat is calling for fan.  That has always worked for me.

I am not at the coach now, but I think I have them in my "box". I will try that as well as spinning the fans. Thanks for the tips.

If that doesn't work you could try unplugging the phone line from the thermostat, wait a couple minutes and plug it back in. Also check the phone line connection inside the AC from below.
