Panasonic dimension 4 microwave/convection oven

Is there a quick fix to error h97?

your issue sounds like low output from the magnetron, if this is the case replacement of the magnetron is the only solution, Here's a link for magnetrons on Amazon to give you an idea of the expense involved:

you may decide to replace the microwave instead of repairing.

There's a grating for the interior light, and another panel a little further back for the microwave output of the magnetron. The microwave panel should not have a hole in it. That would probably indicate some kind of magnetron failure. Not user serviceable. Time to visit a competent tech and/or a service facility.

Hi Michael,

i think something wrong with its high-tension circuit or your magnitron is bad.
the minor fault is open of therm stat for protection.
or burnt fuse in circuit.

regards,
nuwan.

you have a short circuit.
test the a) HV rectifier b) Capacitor HV c) HV transformer d) Magnetron e) test the swich for door for short.f) circuit board main is short.
see the diagrams and proceed.

It sounds like the magnetron may have either failed or is not being supplied with the extremely high voltage required to run it.
Make sure the !!!!capacitor is discharged!!!!! before attempting any sort of repair.
Check the door interlock switches first then the high voltage diode with either an AVO model 8 on high resistance range for short circuit, the capacitor can fail and go short circuit, the feed fuse on the primary of the high voltage transformer and then finally, the magnetron is best checked by substitution.
Hope that helps.

The magnetron (the part that heats the food) may be bad or the circuitry to the magnetron may have burned out. Basically my advice is that if you have no electrical expertise, it isn't worth fixing. The magnetron if bad, costs almost as much as a new microwave. If you open it up (make sure it has been unplugged for a few hours and don't seen any obvious burnt parts (including a fuse and the diodes), then most likely the magnetron is done and a new microwave is the way to go.

Let me know how this works out for you.

Test the high voltage capacitor, the rectifier diode.or the magnetron.

The diode and capacitors can br tested. The capacitor must be allowed discharge before testing, or you risk to get electrocuted, even if power is off. Capacitors can get discharged by shorting their two contacts.
Replace the magnetron if the checks and all of the high voltage component tests are good, but the unit still does not heat.

All locations, and description of this parts can be located using the diagram here: Counter top.

Parts must be tested to find out what is wrong.

Remember that microwaves are potentially dangerous devices if not repaired properly, the job must be done by a competent person.
A microwave energy leakage test must always be performed when the oven is serviced for any reason.

Regarding parts, contact the seller here to purchase parts.

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.

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

check mains fuse and check control circuit and magnetron. and diodes capacitor  high voltage related circuit. small part also gone microwaveoven doesnot works, first check oven and conform which part was spoiled, after that this is worth or not old ovens good compaare to new ones...
