Dometic RM 2652 won't cool on A/C
I'm stumped! My Dometic RM 2652 will only work in gas mode. I have replaced the circuit board twice. I replaced the heating element also. I have check for power to the board, both AC and 12V and every...

Old-Biscuit has given you a clue and your new little fact has me convinced that you have a thermal induced open. It doesn't take a direct strike to an appliance to cause a connection to degrade to a point where it still looks good and tests good with an OHM meter but has a resistance not noticed when cold but opens when current flow heats it up.
We had a strike somewhere in our former condo complex that took out a lot of video equipment and our 240vac element in our water heater. The water heater worked flawlessly until, someone took a shower. After finishing a shower, if someone else took one immediately, warm water only and then cold. Sometimes it took hours before the heater would work again. The problem was an open in the upper heating element. It measured correctly when at rest but after use the open would open and closed as it got hot and cooled.
I'd recommend, checking not only the connectors to the board but how solidly connected each lire is to the connector.
Good luck in finding the problem, it is very hard to find some of these electrical gremlins.
