Question about Panasonic NN-T993SF Microwave Oven

1 Answer

Microwave shutsdown after 24 seconds, does not heat up

The microwave starts up and the turntables turns for just over twenty seconds, but then just stops. The food does not feel any warmer. The power remains on. There are no unusual sounds or smells. I thought perhaps the exhaust vents were covered and the microwave was shutting itself down to prevent overheating, but I cleared any possible obstructions and the problem still persists. The unit is just over two years old.

Re: Microwave shutsdown after 24 seconds, does not heat...

Classic symptom of a defective inverter. It it's under warranty, you're probably in luck. If not, expect repair costs of about $120-150. If you can find a servider who will repair the inverter instead of just replacing it, you can save some money. If you or a friend can replace it yourself, you'll really save, assuming you follow safe procedures. You can find my file "safety.txt" via a Yahoo search. It is part # A606Y5X00AP for model NN-T993S and runs $62.83 plus shipping. The inverter can be gotten from Panasonic at

My microwave turntable stopped turning but the microwave still heats up and works, otherwise.

You didn't say what model microwave you have, but most that I have seen have two separate circuits inside. One operates the magnetron (which makes the microwaves) and the other operates the other things like the turntable or the inside light etc.. It is quite possible that you have a problem in that second circuit. This allows the heating without the turning. To fix this type of problem, if indeed that is the case, requires some skillful trouble shooting inside the microwave which I don't recommend your try unless you are a skilled technician, because of dangerous voltages. Go ahead and post the brand and model number and I can be more specific as to what action to take.

Ge pvm2070smss shuts down

It may be a noisy magnetron if the failure occurs in a second or two of hitting "Start" to begin cooking.

See this FixYa solution. even though your model number is different.

Otherwise, if the internal cooling fan is not running when you are cooking, it will shut down after 30-60 seconds or so and stay off until it cools back down.

My dcs mo-24-Ss microwave oven cannot heat the food after turn on, everything working fine other than no microwave come out

Assuming the turntable, inside light, and internal cooling fan all work when you press "Start" to cook, then I would suspect a bad magnetron, or a bad connection at the "FA" terminal of the magnetron.

If one or more of those three items do not work when you hit "Start", the I would suspect a bad door switch or mount.

The DCS MO24SS is essentially a rebranded Sharp R-530E-series microwave with different cosmetics and a higher price.

The service manual for the Sharp model is here.

The internal Sharp parts in the manual will interchange, but not the external cosmetic parts.

You can order Sharp parts from Encompass here.

Goldstar under counter microwave spindle won't turn

use the common sense, and logically, fix it. God bless you
Microwave Runs, Heats, but turntable does not move This is a fairly easy one. First, make sure the turntable coupler under the glass dish is not broken. Second, on the control board, find the turntable relay and test for voltage. Some turntable motors are 24 volts DC, so make sure your testing the correct voltage. If no voltage from the control board, then replace the control board. Otherwise head towards the turntable motor.
On OTR models, you can get to the motor by un-screwing the bottom panel on the microwave. On countertop models, there will either be a knockout or screw on access panel. Check for voltage at the motor. If no voltage, check the wiring back towards the control. If voltage, then replace the turntable motor. The component list below also shows how to test a turntable motor.

Turntable wheel under glass tray broken

If the microwave comes with a roller ring to rotate the glass turntable then I would recommend that it needs to be used when the microwave is operating, as the turntable rotates the food so it can be heated evenly.

I would recommend checking with your local Panasonic repairer he may have access to a new roller or even a second hand one to tide you over.

GE Spacemaker JVM1533WD turntable sometimes works, mostly doesn't

The part with the three rollers that holds your turntable needs to be replaced if you want it to turn. That plastic and those rollers get cooked over time like everything else. The microwave is designed to basically cook with the moisture in anything placed inside the microwave. Those rollers have probably become warped enough so they don't roll properly when heated and that is why they do work somewhat after a night of nonuse. You may be able to find one at a local repair shop for almost nothing. Those parts are pretty generic. Even at a garage sale or flea market. Other than buying from a local dealer you can go on the internet at and get any part for the microwave. Good luck and God bless you.

Microwave Buzzing, Still Heats, but Turntable And Fan Not Working

This is not safe. If the fan is not running, the magnetron will quickly overheat and be destroyed. We answered this in more depth in the other place you asked it.
