I would say it has an Invertor Board fault.
There are no serviceable parts so call a Panasonic engineer for repair.

Yes if the seal is damaged radiation can and will leak. If not just scape off the plastic and wash with mild cleaner.

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.

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.

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.

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.

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

Unplug the Microwave and remove the outer cabinet. Inside the cabinet will be a thermal insulated fuse, looks like the old buss fuses for early model cars but white. Replace that with the correct fuse which can be found at Lowes or Home depot and see if that solves the problem. Be careful not to touch any capacitors if they are in there.

The fuse is internal and you will have to remove the cover to be able to access it. Unplug the unit. Once you remove the cover, follow where the power cord goes into the unit. The fuse should be in that area. Replace the fuse with the EXACT value of that of the original one.

If the fuse blows again when you put the cover back on and turn it on, then this indicates that you have a problem in the power supply or with the magenetron.

Please let me know if I can be of further assistance to you.

Good luck!

Manufacturers used to include access panels in the rear or side so you could easily change the bulb. That exposed the customer to 110V connectors, and that posed a real liability threat, so they stopped using them.

You now must generally remove the outer cover to replace the bulb.

In many over-the-range models, that can mean having to take the oven down from the wall! For safety's sake, that should be a two-person job.

It's really helpful if you have your original installation instructions to do this.

Many models use one halogen lamp to illuminate the cooktop and another to illuminate the cavity. You must not touch them with your bare skin as the oils will shorten the bulb life.

H97 means the magnetron has lost its power. Caused by a failure of either the magnetron, power supply or both.

Panasonic... | Answered on Jan 30, 2020 | 19 views


There is a problem with the magnetron or power supply to the magnetron.
Take it to an authorised Panasonic Domestic Appliance repairer for service.
