Getting ready to head South next week. After wintering motor home, left it plugged in and with all slides closed. When I went out today and opened the door, I could see microwave light on but nothin...
There could be reverse polarity fuses in the converter. Only the microwave works, What about the air conditioner? Doubt whether you have an inverter large enough to operate the microwave, so I believe you have a 120 volt power issue. Does your rig have an automatic transfer switch for genset or do you have to plug it into a receptacle in the shore power compartment?
