So I have a Dometic Cruise
Air reverse cycle AC/heater that is tripping the breaker. I have two - the one that is functioning correctly is drawing about 10.5 amps while heating
. The one that is not acting right initially pulls about 17 A and then steadily rises to over 20A (when my breaker trips). I've gone and checked the water
flow through the unit and tightened all the electrical
connections. Clearly there is an extra load on the circuit but not being familiar with the system I'm stumped as to what to try to diagnose next. Anybody got any ideas of where I should look for the gremlins next?
