Dometic 2852 refrigerator
When I turn the unit on the Auto Light does not come on and the fridge doesn't fire up on AC or LP. However if I push the GAS button, the Auto light comes on and the unit tries to ignite the burner. If the gas is on it will operate on LP. If not it goes to AC which is not supposed to happen. Replaced the upper control board
AKA the eyebrow. No help. All electical checks out. Heater element obviously works as it heats when it erroneously goes to AC.
Dometic thinks its the main control board now.
I'm totally out of ideas.
Wondered if anyone else has had this issue.
