Having problems with your Air Conditioners ?

Dometic Duo-Therm remote...no display

\015 Went out to prep for a spring trip and noticed there was not display on the remote for a/c - heater. I assume the batteries have died over the winter. I replaced them. Nothing. I pushed the reset button. Nothing. I turn the unit on manually...it runs...nothing to display on the remote. No beeps, nothing. Is there something I'm not resetting?\015

Duo Therm dripping water in camper when shut off. My Dometic Duo Therm Ducted AC drips quite a bit of water when shut off after running for several hours on hot humid days. The condensate lines are open. The lines drip steadily while the unit runs. When shut off the lines flow a great deal of water, suggesting that the pan is full. At this point I notice water dripping from the duct work. Thank you for your help!

Crazy Heat I have a Dometic Duo-Therm Ducted air conditioner with a analog stat. Some times in order to make the heat work I have to: set the stat to cool and set it to the lowest temp setting.
