SOURCE: Replace a magnetron tube

Magnetrons cannot be 'repaired,' only replaced. While the cost of them has decreased by about 75% over the last couple of decades, the parts you receive are often inferior to the original and will show this only after installed and operating and then the time required for different tasks may be much longer.  Unless there is something unique about the unit, I advise replacing it.

SOURCE: Need replacement microwave to fit existing trim kit

Finally built up the courage to call GE Appliance number and weave my way through the phone menu system. Pressed the right menu option (sales) to speak to someone about trim kits. Found out that the trim kit model number is JX1527MWW. Then called back to select a different menu option (other) and learned from someone else that since the trim kit model is more than 1-2 years old, there's a slim-to-none chance any new microwave models will work with it, and even if there was they couldn't easily cross-reference against a model that old to tell me which one (or something to that effect). So I hit a dead end. Only option for me at this point is to buy a new microwave with new trim kit.

(Personal note: I think the trim kit business is a racket, in bed with the microwave manufacturers. Why else would there be no standard dimensions for microwaves by now--like refrigerators have--and why is it a few pieces of sheet metal cost over $150? Pretty convenient that every microwave model needs its own trim kit model!)

Congrats on their sending you the mag!

How did you convince them to do that? Did they make you sign a waiver?

SOURCE: I need to replace a magnetron tube in my Magic

Try Ace Appliance who can cross reference most of these megatron tubes. Most of the time, its getting the access to the tube that will take up most of your time inside the microwave. Also, another good place to find these parts is Daewoo website.

Brand new microwave lights up plate turns around everything works except nothing heats up! Please advise!

If everything works, but no heat sounds like the magnetron circuit has failed. Since it is brand new, just take it back to the store and complaint that it does not work, and ask for a refund or replacement oven.

The fuse blew on my emerson microwave oven and I replaced it. This fuse has now blown. What would be causing this? Thanks....Lee

Usually what happenes is the magnetron is dead, or is dieing. It is using too much power due to overheating, or it is just worn. This is a common thing for older microwaves. take the case back off, and clean the fins on the magnetron this will fix the overheating problem. Be careful. let your microwave sit for about an hour after being plugged in. This lets the capacitors that store dangerous voltages leak off. also make sure the new fuses are ceramic fuses that are rated for 15 amps at 250VAC Do not use glass fuses! You can find a new magnetron on ebay, or on the internet some where. You will need a DAEWOO 2M218H MFI magnetron. I just tore my microwave apart, and realized I have an exact replacement for it. I just swapped them out and they both work. cool. but yeah. that's what is most likely causing it. Good luck!

Convection function not heating from underneath

Sounds like the magnetron has failed. This is the component that produces the microwaves that heats the food.

The cost of the magnetron is about 95% of the cost of a microwave oven. Most people don't, for this reason, replace the magnetron, they replace the whole oven which is probably what you will end up doing.

There is a possibility that the circuit that provides power to the magnetron is faulty and you need to take it apart, find the proper electrical leads and test them with a volt meter. To do this you have to remove it from its mounting and take it apart. It is a fairly lengthy process however.

We used the microwave as a timer by mistake. It shut off by itself. Is it broken?

If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the magnetron thermostat to open.

Then when it cools, it closes the circuit and allows power through again.

If it did not come back on, chances are the magnetron's thermostat (or thermal cutout, TCO, etc. as they are also known) has failed and will have to be replaced.

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

Many brands also have a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

If the parts link does not cover your model, please reply back with your brand and model number so we can help you.

In that case, the most likely problems are:

- loose or corroded connection at the magnetron
- problem or loose connection on the control unit circuit board
- bad magnetron
- shorted high voltage diode

Here are some links you or someone you know can use for test help, but read their safety warnings first:

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.

Can i run my daewoo microwave without a food splashguard

The waveguide cover is usually about the size of a playing card and often held in place by a plastic rivet.

If your waveguide cover is burned, damaged, or missing, it will need to be replaced.

Its job is to protect the magnetron from being damaged due to grease or food particles.

The metal behind the cover should be cleaned with a mild, non-ammonia cleaner before installing the new one. The metal edges of the oven behind it can be sharp, so be careful!

Please reply back with your brand and full model number or visit or
