Hello all,

In a pretrip inspection, I found my dometic thermostat was flashing a error code -E4. After some research, I found this is very common for the brand. It seems the ac is still blowing cold with the E4 but I would like a fix for this.

I came here to this forum for Rpod owners who know.

What is the real problem, How can I reset this error code, and can I upgrade the thermostat for a more functional thermostat, as this one seems to have such a big gap between on and off when on auto cycle.

I want to take it to the lake, not the dealers this week. Any help will be greatly appreciated.

There was a thread on this yesterday. I think the cure was to disconnect shore power and the battery. Give it a minute, then reconnect.

Yup. Thought this looked real familiar. Exactly what TT said: http://www.rpod-owners.com/forum_posts.asp?TID=10295&title=thermostat-error-code-e4 - http://www.rpod-owners.com/forum_posts.asp?TID=10295&title=thermostat-error-code-e4
