Question about Microwave Ovens

1 Answer

Comination Microwave Make  Panasonic Model NN-A752W Problem Oven and grill work fine.  Since last week microwave function does not work. I have tried different power settings. All appears fine, lights, turntable and clock timer.  The trouble is that there is no heat imparted to the food at the end of the cooking time. I have found and checked 2 internal fuses - they are ok.

    Lights and turntable come on but the magnatron does not come on. If I oush hard on the top of the control pannel, the power comes on. It will cook as long as I hold it firmly there.

Generally, the most common causes of a failure to heat are:

- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose connection on the control unit circuit board
- bad magnetron or other high voltage part
I would think it's not a door switch problem since the oven and grill work.

I'd say this is a problem with the inverter or a bad magnetron.

More importantly, 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. You can find one here:

My panasonic NN-8500 microwave/convection oven the microwave part is working fine but,the convection grill defrost is not


Possibly the defrost heater element has failed. You will need to strip the cabinet off and use a multimeter to test the element. May also be the overtemp safety thermostat may have failed.

After many years of good service my Dimension 4 does not microwave. It goes through all the motions but doens not heat the food. the convection and grill functions are working fine. HELP!


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.

Our microwave oven Panasonic NN-S252WF stops after


Our technician suggest that there may be a problem with the Inverter Board in this model, which is something that would need to be looked at by a Service Center.

In rare cases it could be the door switches.

Microwave not working but oven and grill do


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.
