A simple Google Search . . .
What is the E7 code on a Dometic thermostat? When you see this code, the system is telling you that all 120 AC power has been lost and the system cannot operate as it should. That loss of power is for all power modules connected to the system. Checking for a blown breaker is one way to fix this issue.

I guess it is easier for someone else to search for you

Loss of 120 volt power to the A/C.

X2 Makes me wonder...

Saw you also have a MKX - Just had to change the original battery as it failed on my 2017. What a nightmare and gone are the days to remove a few bolts and lift the battery out.
