AFTER SETTING TIME COOK TO 1 MIN 60 SEC AND PUSHING START BUTTON 4O SECS MORE IS ADDED, I.E. TOTAL 2 MINS SHOW ON DISPLAY. CAN I RESET THE THE COMPUTER.


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.

Microwave settings switch off after 22 secs/30 secs


If it stops after 22 seconds, that means the controller has detected a problem, usually a problem with the inverter, controller, magnetron, or a bad connection from one or the other.

Due to the lethal voltages used and produced in inverters, I do not recommend that an inexperienced person work on these.

Microwave runs 3 sec then shuts off.


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.

My panasonic genius old as it is,suddenly stopped working turns itself off after 15 sec not heating is it throw it out or can it be fixed simply????


If it stops at 16 seconds and is a sensor model, it probably has a defective humidity sensor.

Hi there, I have a panasonic microwave which is a few years old now. The problem is that it goes for about 20 secs then stops, the display returns to the time and the light in the microwave goes out....


22 seconds is the giveaway.

In most cases, this is a problem with the inverter or a bad magnetron.

Due to the lethal voltages used and produced, I do not recommend that an inexperienced person work on these.

I would recommend that you contact your nearest Panasonic-authorized servicer.
