    Everything else works -- light, vent, turntable. It makes a much louder noise than before though and wont heat at all.

  • Roger Karas Oct 24, 2012

    The loud noise is not a humming sound and not a buzzing sound. Sounds somewhat like normal just much louder maybe by 3 to 5 times.

  • Roger Karas Oct 24, 2012

    May have smell something burning electronically in last couple of weeks -- don't know for sure. Could this be the high voltage diode?

  • Roger Karas Oct 27, 2012

    Diode failed multimeter test. Replaced it and still have same problem (no heat, loud noise). Capacitance of high voltage capitor measured correctly. I think magnetron also tested positively but will try replacing that next.

  • Roger Karas Oct 27, 2012

    The loud noise has been described as including a buzzing sound by someone with better hearing than me.

    the unit should have a inverter board that supplies voltage and powers the unit---it and the Megnetron are connected.

  • Roger Karas Oct 27, 2012

    In regards to the magnetron, it looks like the manufacturer part number from maytag web site is W10126786. I see this for sale $145 athttp://www.repairclinic.com/PartDetail/M... but I also see similar Magnetron there for $47http://www.repairclinic.com/PartDetail/M... Part # are OM75P(10) and OM75P(10)ESHL respectively. The support person on line couldn't tell me what ESHL stood for

    2nd link above should behttp://www.repairclinic.com/PartDetail/M...

  • Roger Karas Nov 04, 2012

    Fixed the problem by replacing both the magnetron and diode. Prices for the magentron OMP75(10) were all over the place, mostly around $120 but as high as $225. Got a new one at eBay for $50. Simple to install. Works like new now.

    50 is cheap for that part---I also always break the old Magnetron apart for the magnets inside it.

  • Roger Karas Nov 04, 2012

    Thanks for the magnet tip. No health risks or concerns in breaking the magnetron apart?

That is possible but the parts are usually on the inverter board sold as a unit---Magnetron is also possible.

If the microwave oven is 7 years old or less the most likely problem is the magnetron, or the inverter board, cost consideration should be carefully thought out.

Kenmore built in microwave displaying "D" and wont heat.


"d" may mean demo mode. The first thing to try is a "hard reset". Unplug it from the power outlet for 10 minutes, plug it back in, set the clock, then try again.

Wont heat


Hi, there are three issues that will cause a no heat situation in a microwave. these issue are a failed Magnetron, busted cut-off fuse and, failed diode.

I recommend checking all these area that are located inside the microwave for faults.

The most common issue will be a failed Magnetron.

The diode and, fuse will be located on the noise filter assembly.
