My wife & I were relaxing on our 1984 hatteras ED with the big Cruisair unit running in heat mode. The unit when off as the circuit breaker clicked off. I reset the circuit breaker & everything seemed fine. The unit functioned properly & responded to the temperature setting appropriately. When I turned the thermostat (not digital) to the off position the compressor did not go off. The fan quits blowing when thermostat is turned to off. I'm guessing a relay switch has failed and a new one is necessary. Anybody have experience or ideas? I looked back on a number of threads but did not find an answer.
Thanks,
Clarence
