• ** 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.

WMH32519HB Whirlpool Microwave - What's the downside of leaving off the damper for roof venting?

I'm installing a Whirlpool model #WMH32519HB with roof venting:

The damper looks amazingly cheap, noisy, and has large gaps for air to pass around it. Another poster here complained of the noisiness of the damper on a Whirlpool, also with roof venting:

What's the downside of leaving it off? Our roof vent seems well protected against direct blasts of wind. I've had the old microwave off for over a day now and don't really notice any draft; just feels a little cold when my hands are right at the opening. The old microwave, a Sharp, did not have a damper. We had it there for 20 1/2 years; never noticed any problem with a draft.


*I* see no major or minor issue with leaving that off....as long as the house hood can prevent drafts and such.
