Hi fellow rv'ers. I have a 1986 Toyota Dolphin with a Dometic rm2400 fridge. Been using it on AC as the spark from the ignitor wasn't strong enough to light the burner. Before a recent trip I found I could manually light the burner and then the fride worked great on propane. However when we got to our destination we wanted to run the fridge off AC. So I hooked up to AC and switched the control on the Dometic from gas to electric. The next morning we were going to have some cereal and got the milk out of the fridge and quickly noticed the milk wasn't real cold. We had ice in the freezer and it was pretty much melted. I checked to be sure there was AC available where the fridge was plugged in and the was 120 volts AC present. The Ac option has always worked fine up until running it on propane and switching back to AC. Any one have any thoughts on this? Thanks, Vic.
