Hello All, My air cond will not work at all in the camper, it's a Duo Therm model 58915.302 with a Dometic 3109228.001 thermostat. The thermostat will not power up, what can i check for to see if i can get this unit running? Its a older model camper , 1990 Flight Leader in pretty good shape. I dont know if this is the orginal air cond or not. Any help would be a big plus!

This is a forum for Heartland RV owners, and can't offer too much help on other brands/types of RV's.

This AC doesn't sound like anything that is used in a Heartland (brand) RV. Heartland went into business in the early 2000's.

When you say that nothing works, have you checked all electrical supply items like circuit breakers, etc???

Here is a link to a generic manual on early Duo Therm air conditioners: http://bryantrv.com/docs2/docs/olderac.pdf

Good luck!!

Thermostats usually need 12V DC. If the thermostat is dark, start by checking fuses inside the main fuse box.
