Switch 'out of Auto' or switching to Gas cause AC has been lost?
When it swaps does the Auto Light go out?
When it swaps does the GAS Light come on?
Need to check:
If AC Power was lost at storage shed
Check AC Heater if getting power from Circuit Board
*5A Fuse is for the AC Circuit/Element
*Element is a 325W 120VAC ----ohms S/B 44 +/- and draw 2.7A when ON
*Element Leads plug into J7 & J8 on circuit board...black leads
(DC operated Relay allows AC to element when thermostat calls for heat)
Test the Upper/lower circuit board & harness---Pg 13
Test lower circuit board -----Pg 15
DM2862 is Same as the RM2862
*Dometic changed production locations and started using the DM in model numbers.....no design changes/just production indicators
Parts Lists for RM2862---same parts for DM2862
