My dometic Rv air conditioning unit would come on then after

Customer Question

My dometic Rv air conditioning unit would come on then after a few seconds go off. I looked at the thermostat it was blinking e1 on both zones. I played with the buttons for a while and now it only displays zones 1&4, I only have zones 1&2 in my Rv. Even when I press the off button the lights stay on. I have disconnected all power waited 30 minutes, still no change.What can I do?

What is the brand and style of your thermostat? If digital, is it a 4 button or 5 button Comfort Control or a newer version?

I am adding a link to one for you. See the system reset instructions on page 11. Print this out so you have a copy. The error codes are listed as well as the programming guides. Let me know if you still need more after you do this. All follow ups are included in our fee.
