Question about Microwave Ovens

Open Question

Kenmore model 721.63682300 rated at 1200 watts is now producing 400 watts. Before the dramatic decrease is power it made an intermittent buzz when running. Now, there is no buzz and much less power. Any ideas?

There should 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.

At
our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

A loud buzz, hum, or groan is usually a shorted high voltage rectifier diode, but a sound like gurgling into an empty coffee mug is one symptom of a failed magnetron, and yet the mag can be bad without that sound.

Here are some links you or someone you know can use (in order given) for high voltage section test help, but read the safety warnings first:


http://www.gallawa.com/microtech/diode.html
(if it is NOT shorted or burned looking, it's probably fine)


http://www.gallawa.com/microtech/mag_test.html
(continuity can be good even though mag is bad!)


You can find links to helpful exploded view diagrams and part ordering help here.

I'd recommend that your bookmark this link to your favorites.



Accessing some parts may require you to pull the oven from the wall and remove the cover.

If so, the installation instructions are very handy, and it's best to have

two people since the microwave can be heavy and awkward.



You can download GE owner's manuals and installation instructions here.


If it's within the magnetron portion of the warranty (usually 5-9 years) but out of the original full warranty (usually 1 year), then your manufacturer will cover the part cost, but not the cost to visit you or the labor charge to do the work.

If it's within the magnetron portion of the warranty G.E. will send you the magnetron to do it yourself. Call them at 888-239-6832.

Be persistent. You may have to speak with a supervisor.

Kenmore 62463 / 721.62463201 Stainless Steel 1200 Watts Microwave. My daughter used it as a timer for reading and set it to cook for 30 minutes with nothing in it. It turns on but is loud and no longer...


You probably fried the magnetron(it actually makes the microwaves that do the cooking). I bet you will find the magnet is broken(from excessive heat). There should be a diagnostic guide sheet somewhere inside the housing(due to running production changes,this is a guide for the pros to test the power supply,magnetron,etc with an ohmmeter to determine which is defective.

Your microwave oven is 700 watts. Its printed on front of the owner's manual. If you no longer have an owner's manual, you can go to managemylife.com and download or print a copy for FREE. Just type in the model number you provided under the "Manuals" link. Your manual is listed in .pdf (Adobe) format. I hope this help you.

Need small microwave for inverter on houseboat


Look at the rating sticker on the oven and use the AC power rating as your guide. The cooking power of the oven is not important, but the power it needs from the AC supply is. Voltage times current is the supply power needed (watts), and you want an oven that will draw less than the inverter's continuous rating, less any power being used by other appliances.

For instance, a microwave rated for 120 volts AC at 10 amps needs 1200 watts. Your inverter would be OK with this as long as other devices aren't using more than another 1000 watts. You can't use the inverter's peak rating. That's only for brief bursts, like when the microwave first kicks on and draws some extra current.

Any mid-power (600 watts or so) oven should be OK.

Micro Wave shuts down


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

Kenmore microwave 721.80412500


The owner's manual should spell that all out.

But if you don't still have yours, you can download one via Sears' "Manage My Home" site here. While it's free, you will have to register.

(You *may* be able to download it here without logging in. If not, go ahead and register. It's free.)
