A/C, Thermostat, furnace problems
If you have any ideas how I can resolve my problem it will be appreciated.
My MH is a 2006 Monaco Diplomat
I stored my MH for the winter. A few weeks ago while preparing it for the summer on a hot day I wanted to turn on the A/C. I only could see a dim light on the Duotherm thermostat, and could not select any of the functions like fan, cool, furnace, etc on the thermostat.
I then checked breakers, fuses, battery voltage, checked the 50 ampspower supply, ran the generator. Nothing worked.
I then replaced the thermostat with a brand new Duotherm. I plugged it, the screen lighted and saw a message EE ( which means a communications failure ). I did a reset on the thermostat and got a message FF. What does it mean.
I've checked and turned off both furnaces, also the AGS ( auto generator start ) nothing works.
