Microwave Won't Work While Using the Generator 
For some strange reason, the microwave in our motorhome works fine for as long as we're hooked up. But when we used our generator last weekend, I noticed that only the light in the microwave is working.

I checked to make sure that the light wasn't wired into the 12v system. It isn't. Tried to use an extension cord to plug it into another outlet, but still got the same result. All our other systems that run on 110v like our microwave (the coffee maker, TV, DVD, vacuum cleaner, space heaters) were working just fine.

I'm dumbfounded. Is it the microwave, or the power supplied by our generator?

Would really appreciate your input on this. Thanks!

Re: Microwave Won't Work While Using the Generator 
Are you using a built-in generator or a portable one? If it's a built-in, could be that one of the switches in the circuit breaker tripped to OFF.

On the other hand, if it's a portable generator, it could be that it's just not simply able to handle the load. Most portable generators will only allow you to run one "heavy" electronic item at a time. Try turning off the A/C and water heater before starting to run the microwave and see if that will do the trick.

Check the frequency of your generator. Microwaves can be quite sensitive to the quality of the power it's getting.

Check your ground while the generator is running with a polarity checker. The problem might be there.
