Question about Jenn-Air JMC8127DD Microwave Oven
We installed a used Jenn Air microwave that we thought was in good condition (we tested it out before the 3 hour job to install underneath the cabinet!) I was able to heat three items, each for no more than two minutes. On my fourth item, as i pressed the "start" button--nothing. Every other button works except "start". Does anyone know how to begin to fix this? thanks!

the diode is open when the voltage arive at the anode junction it locks off due to the diode is not passing the voltage,change the diode and the microwave will resume operation.good luck.

So it's dead? (No display, no inside lights, no beeps?)
A microwave can be dead for many reasons.
If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the thermostat to open. When it cools, it closes the circuit and allows power through again.
If it's random, it may be a bad connection, usually on the control board or fuse holder.
If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.
If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.
If the fuse is good, it may be an open thermostat or thermal cutout on or near the magnetron or on top of the cavity / body of the oven.

The noise is coming from the high-voltage transformer being overloaded
by something shorting it out. Either the magnatron or the
high-voltage capacitor and diode. Replace the capacitor and
diode then if still not working, replace the magnatron. Its only
affordable if you do it yourself - buy the part on EBAY - lookup
Hope ya fix it!

I always recommend that folks use the vent / hood fan anytime they're cooking with the stove.
Was it on at the time?
If not, moisture can certainly get into the works and cause problems or damage. If it dries out, it's fine but if not, it could cause damage.
