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

You can order Panasonic parts here.

Or you can contact your nearest Panasonic-authorized servicer.

Runs for about 20 seconds then shuts off


In all likelihood the mangnetron has failed, or perhaps even the Power Supply. or a fault that is shutting the system down for safety reasons You need to have it serviced by a reputable service centre/man.
Ensure you get a firm "Quote" before proceeding, and remember these days the cost of repair can equal or exceed the price of a new one.

22 second shut-off


If it stops after 22 seconds, that means the controller has detected a problem, usually 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.

You can find an authorized Panasonic servicer here.

Shops generally charge about $75 for a home visit, then about $75-90 to do the repair work.

You can price Panasonic parts at Tritronics, but if you don't find what you're looking for there, try here. Shops might mark up parts from 25-100%, depending on the cost of the part.

If nothing else, you can save about $75 by taking it to the shop yourself.

I'd say it would run about $200 or so if you take it to the shop.

Turn off after 4 seconds


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.

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.
