AC not working

2011 Lexington 265 a/c quit working. Working 3 weeks ago but yesterday when I tried it it would not turn on. No fan, no compressor. It has the single zone LCD thermostat which is giving a E2 diagnostic code. Despite 2" of manuals, I do not have a manual for the AC (Dometic 640315.301J0) not the thermostat (also Dometic) Tried Dometic website but was unable to locate what the E2 means. Can anyone help?

This seems to be somewhat common with this thermostat in high temperatures. Here is another thread with solutions ...

Thermostat says E2

Good luck and stay cool

By the way, since you did not get a manual, I just uploaded the manual for this t-stat to our Downloads section. Go to Thermostat - Dometic Single Zone LCD for the specific manual.

Thanks Triguy!! Yes, the MH was over 100 in there yesterday and quite a few days in the past 2 weeks. Cooled the thermo down, AC started up no problems. Have down loaded the manual also. Now just need the manual for the AC. Hopefully Dometic will handle that. Thanks again.

Glad it worked. Sorry I don't have the AC manual for that Dometic AC. If you find a downloadable manual, feel free to upload it to that section I referenced earlier.
