Jaydrvr Posted March 14, 2021 Report Share Posted March 14, 2021 (edited) Our a.c. system quit today and none of the usual resets are working. I can't see how to open the Dometic thermostat to check the connections and I don't wish to just break it off the wall. There doesn't seem to be any useful info available online, or on my go-to, YouTube. Surely, someone knows how to do this, probably many someones... Just not this someone. TIA Jay Edit: The zone 1 number is blinking continuously, regardless of what I do. I'm assuming that's a communication issue?? I'd like to eliminate everything at ground level before I venture up on the roof.. Which I may never do....

Wrknrvr Posted March 15, 2021 Report Share Posted March 15, 2021 Do you have a picture of the thermostat so we can tell exactly which model you have. Then we can figure out how to reset it. And if needed, continue on for more troubleshooting. We still are relying on heat. Up north, Vern Quote Link to comment Share on other sites More sharing options...
Jaydrvr Posted March 15, 2021 Author Report Share Posted March 15, 2021 Vern, I moved it to technical tips. There's a picture of the correct one there. Thank you for your help.
