E4 Error Code on Dometic Thermostat
While we have found what the error code means, the manual shows nothing on how to "reset" or fix. Dometic says, under warranty, take to dealer...Dealer says, hummm...I need to find out what this is...

Remove the DC fuse for furnace........leave it out for 1 minute then re-install fuse. See if that clears the error code.
Sounds like you have one of the Dometic T-stats that have the 'outdoor sensor' without anything plugged into ambient sensor on main control board (A/C Unit)
