What is the make and model of the thermostat?

Customer: replied 1 year ago.
xx I am not sure I left the job
Customer: replied 1 year ago.
Cool furnace
Expert:  Randall replied 1 year ago.

Single Zone thermostat. E1 is a communication fault. That is usually in the cable at one end or the other. Clean those and be sure they are dry and replug. See if that allows you to reset it.

Unit has been off for two weeks do those low voltage wires go into the roof compartment?

To the A/C and can usually be accessed from inside the coach once you remove the ceiling grill.

I am not getting 12 volts to the control on the a/c
Expert:  Randall replied 1 year ago.

Is this a new installation or one that is OEM installed?

Customer: replied 1 year ago.
Oem
Expert:  Randall replied 1 year ago.

Some of these get power to the AC from the furnace circuit. Check that fuse or perhaps the circuit breaker at the furnace (depending on what make and model you have).
