I've been fighting the same problem for over a year now. My front tv, rear tv, and microwave will turn off and back on at random. According to the schematic from Fleetwood they're all on the same loop. Nothing seems to cause it to occur....ie outside temp, demand on electrical system, generator or plugged in, rough roads or parked. It occurs totally at random and sometimes it'll work all weekend with no problems. We had the shop look at it and all they could find was the house batteries failed load test and needed to be replaced. After replacing the batteries the problem was still there. I've checked the inverter several times when it occurs and only
ONE time did I get a fault light indicating overload/overtemp. I pulled the inverter and with the cover off slowly warmed the heat sink using a heat gun. The fan came on and off as I applied and removed heat so I'm assuming the cooling fan is working properly. Also, the heat sink was not extremely hot when the fan came on. I've also checked the inverter several times while camping and the fan is running. I've never found the inverter to be hot and rarely is it even warm to the touch. Being as it's a combined fault overload/overtemp I'm not sure which it's indicating.
It's a Xantrex Freedom Inverter/Charger and the RV is a 2001 Fleetwood Expedition 36t.
Our next option is back to the shop for $125/hr troubleshooting. Since it doesn't happen all the time it could add up really fast!!!
Any suggestions would be greatly appreciated as I'm at a total loss as what could be the problem!
