Question about Panasonic NN-H664 Microwave Oven

1 Answer

Micrwave does not heat, and turns off by itself before time

My microwave only runs for 37 seconds, no matter how much time you set it to, and then it just turns off. It also does not produce any heat. Once it turns off, if i push buttons on it, they beep, so power does go through, but I can't understans why it's stopping so abruptly, and always after 37 seconds...

    Same thing with me....I turn it on it sort of makes a few "poof" sounds a bit like popcorn popping real slow and then stops at around 30 seconds...do you think this is a fuse issue as well?

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.

H98 error message. Micowave not heating, stops after 37 seconds


HI. in most cases, this will lead to a failed Heating device(magnetron tube).It would be wise to check the Magnetron cutoff fuse to be sure of its integrity. if the fuse is blown, simply replace it. if the fuse continues to show continuity, replace the magnetron.

(((The fuse is located inside the unit along side the magnetron)))

Microwave turns itself off after a couple of seconds


Q - My microwave seems to shut off every once in a while, what might be wrong?
A - Make sure you hear the fan is still operating in your microwave. Next is to make sure the air intake grill on your microwave is not plugged up with air borne dust and dirt.
Q - The fan in my microwave oven is not running will this hurt my microwave?
A - YES, the fan cools the magnetron and electronics, take the microwave in for service, most fans are not too expensive to replace.
Q - My microwave blows the fuse inside itself as soon as I push the start button.
A - Usually a shorted high voltage capacitor...see components section.

Panasonic Microwave only works for 37 secs no matter what time setting


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 in inverters, I do not recommend that an inexperienced person work on these.

On this model, it should be a defective secondary (top) door switch or the door switch mount.

If this switch fails to be activated, the oven will seem to run but not heat and the turntable will not work.

Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.

Door switch or mount trouble can be caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

One test that sometimes helps is to gently lift up (and/or push down) on the door or handle as you try to start it. If it works or tries to work, then it's a door switch mount or door alignment issue.

If you or someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa:.

You can find helpful exploded view diagrams and order parts by entering your full model number here.

There may also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

I'm confident this will be a FixYa! We're happy to help you and we'd appreciate your thoughtful rating of our answer.

Micrwave starts but then quits


Microwaves should only be worked on by fully qualified repair people and my advice to you would be to bring it to such a person,they can be dangerous to work on due to the presence of such high voltage, other than changing a light bulb any other repairs are out of limit.

Since you tested the door switches (my number one suspect) I would think you have a bad relay or a bad connection on the control panel circuit board. We repair these nationwide for $32.50, which is usually economical for most models. Just to make sure you have checked the door switches thoroughly, you can find my helpful text file called "doorsw.txt" via a Google search. It has important safety information and tips.
