Dometic won't switch from electric to gas

[jdanielii]

My 1999, 25' Safari has a Dometic RM 2652 in it. When shore power is removed it switches to gas but the flame goes off after a few seconds. It acts like it senses "NO FLAME" and shuts the gas off. Have replaced the thermocouple to no effect. I suspect the control board. Is there a method to trick the board into thinking the flame is OK to see if the rest of that circuit works. I hate to replace the board if that isn't the problem. Thanks for your help.

Check the DC breaker. I had a similar symptom which eventually lead to buying a new fridge only to discover that didn't work which then led to the $4 breaker.
