SOURCE: NN-T990SA Panasonic Microwave Stopped Heating

This model uses an inverter to produce high voltage instead of a convential transformer system. While an inverter (switched-mode power supply) is more efficient from a power consumption standpoint, it is more complex, thus more statistically prone to fail. These should only be examined and worked on by someone who has the necessary technical qualifications. Seriously. Often the machine-soldered connections in a microwave inverter are too weak, so they eventually fail, especially if heat is high in the area. They sometimes fail catastrophically. When not catastrophically damaged, you may hear clicking or squealing and may smell an electrical odor, which is sometimes obscured by the cooling fan. Some manufacturers do not encourage or assist technicians to repair microwave inverters. Most offer the inverter as a whole assembly. But sometimes that is actually cheaper than the time and labor required to fix the old one. If a technician is willing and able to troubleshoot and repair the inverter to component level, it will may be expensive, but may be worth it, especially if he or she will resolder and reinforce connections as needed as part of a thorough repair. That could easily make your inverter beter than a new one! You might be able to get some verbal estimates if you call Panasonic-authorized repair shops and ask then specifically about inverter repair and inverter replacement costs for your model number.

SOURCE: Microwave won't heat/Makes buzzing noise.

The symptoms you are describing are typical of a magnetron that has gone bad. Continuing to attempt to use the oven in its current condition can cause further damage. So, I would recommend not using it. Microwave ovens are considered dangerous and repairs should not be attempted by anyone that is not electronic saavy. The High Voltage Network inside the oven has voltage potentials of 14,000 volts and higher. If you feel this is something you wish to attempt, the Magnetron part number is 1156751 and costs approx. $158. Keep in mind, if the magnetron has been arcing and making a burning smell you may have burned the protective coating that lines the walls of the waveguide. If the waveguide is damaged it is not repairable. I do not know if this is a replaceable item on your model microwave. Double check your warranty information and/or owner's manual. In many cases the magnetron is warranted for several years beyond the limited warranty that comes with most appliances. Post back with comments and let me know if you want me to assist you further. In addition, if you provide me with your EXACT model number (located along the door opening) I can narrow down parts a little better. I know this all sounds discouraging, but I do hope I have been able to help you.

SOURCE: reheating doesn't work

Hi There!
The magnetron may be faulty. When measured there should be no reading between one of the terminals and the outer case of the magnetron. Also check High Voltage Fuse( Normally a red wire with a white plastic capsule in the centre) and the High Voltage Diode(Situated between earth and High Voltage Cap). Be sure to unplug from Mains before working on the unit.Good Luck, JUS004

SOURCE: Sharp microwave runs when door closed

This is usually caused by either a bad door switch, a loose door switch mount, or sometimes a problem on the control panel.

I would suspect the door switch mount has a broken tab allowing the switch to swing down when the door is closed, not allowing it to really be activated.

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

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.

If you or a friend 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: http://tinyurl.com/yzjozk

My still fairly new kenmore 1000 watt microwave appears to be operating fine but doesnt heat. What might be the problem?


When you hit "Start" to microwave, do the inside light, cooling fan, and turntable all come on?

Any unusual noises? Is it louder or quieter than usual?

We have a sound clip of what a microwave should sound like when the cooling fan and high voltage section are operating here.

Post a new help request with the answers to these questions as well as the full model number from the tag on or in the unit.

A full Sears/Kenmore model number has 3 digits, a dot, then 8 more digits, such as ###.########

What is the highest power setting? choices are low, defrost, medium, roast and reheat. no high???


Most microwaves run high at default, if roast and reheat are given that is your high setting, take one cup of water and run for 1 minute in each setting, the water that is the hottest is the high setting.

Kenmore microwave loud popping noise when start


That sounds like maybe a high voltage wire or component is running too close to the chassis or one of the components connected to it.

Gruesome as it sounds, sometimes a pest can get inside the works and can move wires around or be killed, then its carcass can conduct electricity and cause arcing.

It may instead be a failing high voltage diode.

To find helpful exploded view diagrams and get part numbers, you can just enter your full model number (66562619200) at the Sears parts site.

Here are some links you or someone you know can use (in order given) for test help, but

Microwave is on when you shut the door


I tried all the things on your website. Holding the clear button , unplugging,...

So I went back to the last operation that I was doing when the problem started.
I was using "reheat" so I put a glass of water in the micro turned on reheat 1 serving.
It started and then I hit clear after a few minutes and the problem went away.

Kenmore microwave model 665.68681891 runs but won't heat


Test the high voltage capacitor, the rectifier diode.or the magnetron. If all this are fine, test the control board.

If it additionally does not spin and no light, then check also the door switch and fuse.

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. (here in UK).

Plate won/t rotate no reheating


PLease open the housing of turn table motor at bottom of the oven and check for the AC input voltages on motor terminals as specified on sticker on motor. for no heating please check fuse between high voltage transformer and high voltage capacitor. Also check high voltage Diode and Magnetron.Please please don't try to measure voltage on terminals of magnetron.
