When I turn the truck off, the AC is no longer available and computer automatically switches to propane.
I assume fridge set to auto? so that it switches as designed when 1 source (default AC) not available. Ive never tried the manual AC mode setting, I use the DC, when truck shut off fridge shuts down, when restarted the fridge starts up again in DC. I assumed that what ever mode its set to it would restart when that source available again, except gas as it throws code and have to reset.
Never tried to disable the igniter, if it would still trigger error code, I would guess it would. I 'think' flame across the electrode would need to be duplicated-just a wag.
For the amount of time to refuel etc I wouldn't think switching to DC be very beneficial so would just set to AC instead of auto IF refer will restart in that mode.
Never mind... cant get to AC without being in auto, just went and looked. Tired to unplug and also ground electrode- don't know what is used to trigger board that it's lit in gas mode.
Turned to auto/AC then turning off breaker fridge switches to gas- at any point up to when 'check' comes on, restoring AC power fridge starts again AC. Once 'check' light on fridge it does switch to AC when power restored but doesn't start, Have to turn on/off fridge clearing check to get it to restart.
Which does work. In AC/auto fridge on, turning off DC (pulled fuse at converter panel) fridge shuts off. Reinserting fuse restoring 12v clears code, fridge restarts in AC. Which basically is what I did only for DC mode. Toggle switch in cab that triggers 40 amp relay (even though your only powering controls)on fridge 12v line. Mine is 2001 Dometic. Need to verify panel retains last setting, some dont. But all you'd need is a relay and run a trigger from cab.
