Dometic RM2801 Gas Electric
[Gary R.] I have a new Dometic RM1272 and it would work perfect on Gas but would start to warm up when switched to electric. It was still under warranty so I took it in and the repairman said that there were TWO heaters for electricity and only one was working! He said he changed the bad one out and now it works good. I never knew that there were two heaters for electric! Good luck Gary.
