New fridge won't work

THANKS A LOT FOR ALL OF YOUR HELP GUYS. The Dometic model RM 2454 actually has two different sub models based on the production #. My particular production # unit does not have a thermocouple. I called Dometic to verify this. They were very helpful. They said on my unit there is a sensor inside the igniter itself. So I ordered an igniter today. The sensor inside the igniter sends a millivolt signal to the board and I guess that is what tells the board if there is a flame present based on the signal being sent in a certain range or not sent (something like that).
