When I bought the 79 sovereign
, it came with a newish microwave. The trailer is now installed at its permanent location, but hooked through an extension cord to a neighbor's GFPC outlet until I build a power shed.
When I tried the microwave, it would start "sounding" ok and then sound as if it was straining after about 1/2sec. I assumed the microwave was failing, so got a second microwave. This microwave does the same thing. Occam suggests that the problem isn't in the microwave but in the power supply.
I need to lug the microwave to the neighbor's and try it directly there, but I'd be very surprised if it didn't work just fine over there (he's got a simple electrical setup connected to the grid.
Is it possible that something about the power setup in the trailer is causing the problem? Some sort of maximum draw problem? The highest wattage thing we plug in (not at the same time as the microwave) is a space heater, but it's hard to know if it's operating at 100% power or not. Its fan isn't slowing down after 1/2 second.
Any pointers appreciated!
