Main A/C unit code E-4

[Ultraboy]

My Vengenance 39r12 has a main a/c unit controlled by a dometic wall thermostat which also controls the furnace. The a/c works great but this trip, it constantly flashes code E4. I checked up top, and don't see anything obvious, and it is working fine. There is no manual for this unit or control in the 2" thick stack of paperwork we got with the camper. I emailed the dealer, but with the holiday, didn't expect an answer. Heading home today, I'll call them tomorrow, but sure would be nice to have a list of the codes.

The codes are in the Dometic manual and is on line. Google Dometic and pick your roof air set.

Thanks guys! I appreciate the info and link! I have the single controller, but the error codes are the same. We've camped 9 nights in two trips, and this is the first 'problem' we have had. Just lucky, I guess.
Thanks again, Google to the rescue!
