I was reading the posts of how to fix Dometic issues and wanted to chime in with my issue and if anyone had seen it or knew how to fix it.
I have a 4 button dometic with two AC units.
When it worked, the digital display showed all the info including the zone 1 or zone 2 that I was configuring and looking at.
All of a sudden when I turned on the comfort control the zones did not show up on the display, nor did either of the AC units work.
After fumbling through a few wires on the AC 1 unit, I disconnected one of the phone connector cables and the front AC unit began to work. The rear still would not work. Also after having the front AC run for a while, I noticed it was not turning off when the temp on the display (by the way the zones 1 and 2 still was not displayed) was reached. It just runs continuously.
Any thoughts or ideas? I really do not want ot go buy the 10 button unit with control boards if I dont have to..

Your 4 button is over 20 years old and they dropped the 4 button due to the same issues you are having. You can either buy the 2-- 10 control boards and the 10 button or you can buy 2 -- 5 Button control boards and the 5 button. You also need to replace the 4 wire phone end plugs as a maintenance issue. Doug
