    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.

Hi,

Almost 14 years after installation, our Kenmore wall-mounted microwave started playing up this afternoon. Part of the digital display was out - not all of it, just some of it. It seemed like if you could press 1-minute-start, it would start operating (not sure if it heated anything) Now, the number pads and the start and stop buttons will register a beep, but nothing happens if you press start. All other buttons are dead. Despite power-cycling (removing plug from power socket for 10+ mins), nothing has changed.... the display just scrolls (partially) "Set time / Power / Press start" - but pressing the "active"buttons doesn't do anything to change this.

Any suggestions?

Thanks

Hi Jeff,

Thanks for the "good" news.

I've sat on this for a month, as we're been preparing to move out of this house; while I discovered the "add minute" function worked on the microwave, so we've been heating things 1 minute at a time!

Just read thru the installation instructions. Its a standard 30" wide (29 15/16" to be precise), and appears to be held in only by two large bolts from the wooden cabinet above, and two support hooks on a wall bracket mounted to the rear wall.

Is there any chance that these units are standard-enough that I could just unscrew/unhook this old microwave, and hook/screw a new one of similar dimensions in its place? Or is that just a laughable idea? :) If its going to need a new mounting bracket and new attachment method to the cabinet, I'd better get someone who knows what they're doing to do it for me....

Thanks,

Ross
