I have a spare Dinosaurelectronics board that didn't fix my old fridge. I pulled it with the complete control module and relays. I will try to find/post the parts in case you could use them.
Tt had not been used in a year, works on electric but won't switch to gas once unhooked from ac power and heater will not turn on my daughters rig, when they come back over we will try some of these tips. thanks for all the quick answers
Most common reason would be it's not GETTING any gas, for some reason. That's assuming, as others say, that electric power is not available. If it's when switching manually then the switch could be the problem but it SHOULD still switch when electric is not available AND gas is.

had same problem on mt TT this summer. If its a dometic there is a module that lets it switch over. $75 service call plus part cost. Can get them from the net for $29 if ya look. But sure was nice to get it going again. If ya need a pic let me know.
