HELP A/C stopped working !
2011 27' International with a single Dometic A/C unit. We get an E1 error code message. Which, I know means a loss of communication between the CCC thermostat and the system power module boards. How do I reset the system ? Resetting the circuit breaker does not help. Right now the A/C tries to come on, but shuts down after 4-5 seconds. Being 4th of July weekend doesn't help trying to get a service guy out to the lot. Any thoughts on what I can do with limited knowledge & hand tools ?
