I have a 28BHBE. One thing I notice is at times when I switch from electric to propane, the Fridge flame does not ignite. So, about 15 minutes or so before departing, I will switch over the refrigerator, and watch the lights to see if it don't start flashing. (Most of the time, it does) So, I switch it back to electric then wait a few seconds and then switch back to gas. It will usually light after the 2nd try. If It don't, then I go outside, take off the black refrigerator cover, rotate the flame access cover, unplug the electric plug from the outlet there inside the housing, then plug it back in, this forces the refrigerator to go from gas to electric, when unplugged, it goes to gas. If I see the flame ignite, I then go inside and switch the switch to gas. Outside and plug the power plug back in. I always double check to make sure the refrigerator is running on gas before I leave.
The light takes about 20-30 seconds before it will tell you it's not igniting and starts flashing.
