Atwood Combo will not function on AC
In our new 316RK, the propane side of the hot water heater works fine, but on the AC function will not work at all.
When I switch on the AC remote(in the box by the door), the indicator comes on, and shortly after that the DSI Fault indicator comes on.
In propane mode, the heater runs up to temp and shuts off the burner(normal op), Then when I switch on the AC, and the temp goes low enough for the unit to turn back on(AC op this time) the DSI Fault indicator comes on again.
The dealer that we purchased from said they had replaced a bad board on the unit, and it worked fine when picked the trailer last Monday.
I can hear a noise from the potted board when in AC mode- sounds like a oscillator noise. Not sure if normal or not.
Anyone that versed in troubleshooting these units?
We are 150 miles from dealer parked until September.
