• ** REMEMBER! **The microwave can still shock you even unplugged!!

    ALWAYS discharge the high-voltage capacitor first if you even think your hands will come close to any HIGH VOLTAGE components.

    Jeff mentions this: Anything in the high voltage ( magnetron, capacitor, diode, wires to and from ):
    ...Use a metal ( not the shiny chrome type ) screw driver with a insulated handle to short across ( touch both at the same time ) the terminals of the high voltage capacitor to discharge it.

We purchased a new over-the-range microwave with exhaust fan. My husband installed it and we did a test run (the old one would trip the breaker).
The microwave works but the exhaust fan runs too. I know the fan will kick on if the range is hot, but this was not the case. What did we do wrong? When the microwave is on, the fan is on.

Are you certain it is the exhaust fan? The microwave has a cooling fan that should run whenever it is heating. I've never heard of a model that would run the exhaust fan too.

If it really is the exhaust fan running, I don't know any way and incorrect installation could cause that. You might have to call for warranty service.

Thanks Dan.
So do you think incorrect installation could be the problem? It definitely sounds like the exhaust fan to me but I only ran it once. It’s on my mom’s stove/microwave. I can try calling for warranty service. This thing has been a royal pain in the butt.
