Throw it out. The door is too much to fix. A new microwave at WalMart is $30 or so.

SOURCE: Microwave shuts off after 3 seconds

Although your model number doesn't seem to show up, the NNS950-series units are powered by an high-voltage inverter. And yours has failed. 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. Sometimes a whole new inverter is 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 appliance / microwave repair shops and ask then specifically about inverter component-level repair and simple inverter replacement costs for your exact model number.

SOURCE: Microwave shuts off after 2-5seconds

The problem is most likely the magtube, it takes aprox 3 sec for the tube to energize and then it kills the microwave. If you drop the control panel away and start the microwave 90% of the time it will cook fine.

Sounds like the problem is in the high voltage. Most common would be magnatron, capacitor and diode. For safety reasons this should be checked by a professional. Look in your owners manual because some high voltage parts have a longer warranty than 1 yr.

Chances are your magnetron is overheating, activating the magnetron thermostat, which resets and restores power when it cools.

Your manual may call for you to put a paper plate under the popcorn bag to heat better and to protect the turntable. (And always place the food slightly off-center on the turntable, for the same reasons!)

You should first confirm that the outlet reads about 110-120 volts AC and that the microwave is on its own breaker. If a microwave shares a breaker with another high current device (or even lights) it can affect operation.

Then be sure the microwave's internal cooling fan is running.

If this is an over the range model, it will also have a exhaust hood vent fan which you can turn on and off at will, but this is not the fan I'm talking about.

The internal cooling fan should be on whenever the oven is cooking. If not, the magnetron can overheat and eventually be destroyed.

The next issue is how long you've had the oven.

If it's within the 30-day dealer exchange period, I'd take it back for a new one pronto.

If it's within the full warrranty period (usually 1 year) Daewoo's service center should fix it free.

You can visit Daewoo online or call them at 1-800-323-9668 or 1-800-553-4355 to find parts or find your nearest authorized service center to have them do the work.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

GE Spacesaver microwave always runs when the door is shut


I see this all the time. In all likelihood the mangnetron has failed, or perhaps even the Power Supply. or a fault that is shutting the system down for safety reasons You need to have it serviced by a reputable service centre/man. Ensure you get a firm "Quote" before proceeding, and remember these days the cost of repair can equal or exceed the price of a new one.

GE microwave won't turn off


Just checked the GE website. Had the same problem with my 5 year old microwave. GE website says to close and open the door quickly three times. First time I did this it didn't work. Second time I closed the door with some significant force and reopened it more quickly. Worked. Unplugged the microwave, plugged it back in, still fine.

Sounds like a defective door interlock switch or a broken switch mount.

We repair these for $39.95 for customers nationwide. Reply back if you still ned help.
