We experienced multiple GFCI false trips and refusals to reset with a Magnum MSW inverter. All original by the coach builder, and obviously it can work for many people. I did some research and turned up a white paper by a maker of GFCI outlets stating there were known compatibility issues with MSW.
Our inverter was replaced under warranty with a PSW, no problem since. And the microwave heats faster on PSW as well.
I am in the same boat. My electrician buddy said to swap out the plug see if that works, and it did, slight hum still. I tried another inverter and it worked too. My last few inverters were MSW, but never had this problem. I bought what I thought was a decent one however it looks like I'm wrong.
I will return it and get a PURE SINE, **** their pricy though. It sounds like its worth it.
