Control panel operates normally. Timer counts down, fan turns on, oven light on. The turntable doesn't rotate and the microwave doesn't heat. Symptoms came on simultaneously. Perhaps not a coincidence, it occurred after popping two bags of microwave popcorn (possible low load problem?).
I've already opened it up (yes, I read and adhered to all microwave maintenance safety guidelines). I checked all the connections and the only fuse I could see (20 amp, checked good). Put it back together and still no workee.

If your microwave is a 220 then reset the breaker by turning it off for 10 seconds and then back on. Then check it. Since you replaced the magnetron, the signal to the mag is interrupted. Did you replace the control panel? If so, then look to see if it is wired back in order. Does the fan operate when you open and close door? If not, then check door switch.
May be one of the components in the High Voltage circuit has failed...Usually there is a relay or semiconductor switching device that turns on a tube called a magnetron..this magnetron is what heats the food...any one of the components in these circuits could have failed...I would have a repairman look at it to see if would even be worth it to get it fixed.
If everything comes on when it is started, like the light in the cavity
and the fan (which one can hear running), and the timer counts down but
it doesn't heat, the problem is probably isolated to the high voltage
section of the oven.the magnetron i guess is kind of faulty and this is the most expensive part in a microwave oven. If the display is on and the oven won't come on and run, there
may be a problem in the door interlock system or the thermal protection
system. wish yo good luck,
Hi. You probably have to switch the oven onto manual control. Auto would turn oven on at a preset time. Is there a button with a hand symbol on it? This might be manual. Timer should show clock when in normal manual operation.
it starts chiming every min AFTER the timer counts down the allotted time?? thats normal operation its remonding you that the timer has completed cookin and to remove food from oven.. it will continue cooking with residual heat if not removed
This is most common in over the range microwaves. Cooking grease migrates into the door switches, resulting in the symptoms you list. Replace the door primary and secondary interlock switches and you should be cooking again. NOTE: be careful not to touch other wires! Even with the unit disconnected from power, if you happen to have a bad bleeder resister in the high voltage capacitor you can still get a nasty zap !
check incoming electric first, pull it out and gain access to main wire terminal, With multimeter set to at least 250v AC , check your power across the wiring as such. black to white (110v), red to white(110v) and then black to red 230v. if that ok ok turn, then start ckin elements for continuty also there might be a thermostat( usually an 1 in. round component with 2 wires located right inbetween the elements that has gone bad, will show no continuity. ck that before electronic control the fact that its clickin sounds like the relays are workin properly
