Runs 20 sec stops reads F1E5 - KitchenAid KEMS309BSS Combination Microwave Oven 30"""

A door switch may be defective due to opening the door while it's cooking instead of pressing the "stop" pad first, or a switch's mount is loose, misaligned, or broken.

probably ur stirrer motor burn or temperature cut off tripping due to hi temp of ur cavity casuse by defective coling fan

just go to breaker box and turn off the breaker that powers the stove

There are sixty seconds in a minute, so 1 min 60 sec is the same as 2 min. If you want 40 seconds less than 2 minutes then set it for 1 min 20 sec or for 80 sec.

I had the same problem and was on the verge of destroying the entire kitchen in a fit of rage until I read MicrowaveSvc's post. Thank goodness it worked. I unplugged it for a few minutes, and now it works fine. THANKS MicrowaveSvc!!!!!

mtystufquit - We've already discussed this by chat & e-mail, and if and when you need further help, please let me know.

"If the digital programmer circuit / controller does not get a feedback signal from the inverter for a period of 3 seconds, the controller will stop the cook cycle."

ddmdavid - you probably have a bad door switch or door switch mount. Please see these links.

If you still need help, please create a new post with your brand and model number.

When talking about "Power Level", there is a misconception that the cooking power is being adjusted. This is not the case. The user is actually adjusting the duty cycle of the Magnetron. For instance at 30%, the Magnetron will be turned on for 20 sec. and off for 40 sec. A loud 60 cycle hum is usually caused by a shorted Magnetron. Thus the unit is not economically repairable.

if appliance runs for approx twenty seconds this is nearly always a magnetron fault usually a cracked magnet or burnt out anode the electronics are detecting an unusual power fluctuation and shutting appliance down for safety you will need service tech to sort.
