Greetings and thanks for your help on the "2013 Flying Cloud Furnace" problem, that I asked about earlier.
Our main 30A circuit breaker trips when we add loads while the heat pump is operating. We first noticed this at the dealership when we tried to operate the "convection microwave" while the heat pump was in use. The 30A breaker would trip every time the HP and Microwave were on at the same time.
The dealer did some trouble shooting and found the battery charging system was throwing spikes so he replaced this and also replaced the 30A circuit barker but the problem persisted.
The dealer spoke with Airstream and was informed that the convection microwave would overload the circuit when the HP was operating. This was a surprise since a simple load analysis should have identified this problem. This configuration should not be offered as an option since failure is certain.
Our dealer was not aware of this built in problem by Airstream. I asked the dealer if he could swap out the convection microwave with a standard microwave that did not draw so much power. He is looking into this.
This morning I was making some toast in a plain Jane toaster and the 30A circuit breaker tripped. All that was on was the overhead 12v
lights the heat pump and the toaster. This was steady state with no compressors or starting.
I reviewed the manual for the Dometic AC/heat pump and it shows that the rated load for the compressor is 12.5 amps and the fan 3.5 amps, or 16 amps for the heating/cooling. It seems like the remaining capacity on the 30A breaker (14 amps) should be enough to operate other household appliances.
I'm beginning to wonder if any microwave will be compatible with my new Airstream. Or perhaps there is something else causing an excessive load.
I would appreciate knowing if anyone else is having this problem, any comments you have regarding this problem and any possible solutions you could recommend.
