My panasonic microwave stops working after 6


If it stops after 7 seconds, it has a problem with the inverter.

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

Microwave stops after 24 seconds


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.

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 inverter-based models.

Operates for 3 seconds on microwave then stops


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.

It could possibly be as simple as a loose connection in that area. The repair shop your friend used may not have been Panasonic-authorized.

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.
