Here is our electrical problem with our 40X 2008 Fleetwood Discovery: The shore power is coming in as normal. We are plugged into the CG provided 50 amp power at the pole. This power switches to inverting. The shore power breakers at the pole are not blown or flipped off. Also, there are no breakers thrown in the breaker box inside the coach. To fix the situation, we flip the pole breakers off and back on (maybe don’t need to do this but we do), press the three switches on the side of the magnum inverter and turn the inverter off and back on. Everything comes back to normal, meaning that we have full shore power with no inverting. We have the “MS Series Pure Sine Wave Inverter/Charger.”
When the problem occurs (power switches to inverting), the microwave or dryer is usually running, but not always. It used to only occur if the microwave or convection oven (within the microwave) was running for more than 10 minutes. Now the problem is occurring with very little increased amperage.
We had a mobile RV technician come and he tested the power at the CG pole. He suggested that the breaker at the pole be replaced. The CG owners did this. He also checked the power in the breaker box inside the MH. He said it was fine. The technician said the microwave is wired through the inverter. He suggested replacement of the electrical outlet box in which the microwave plugs into. That was done.
We still have our problem. It is occurring multiple times a day now. We have had this problem at other campgrounds. Since this CG has changed the breaker and we’ve had the problem before this CG, I don’t think it has anything to do with the CG power.
Any suggestions on what may be happening and how to fix it? We are currently in the Rio Grande Valley in south Texas. Any suggestions as to who to use for RV electrical repair?
