Question about Kenmore 62702 Microwave Oven

1 Answer

Please help....It was just like a "Frankenstein" movie.

My Sears Kenmore Microwave was just manufactured in Oct.2004. Last night I put a plastic bowl of frozen veggies inside, closed the door, & pressed # 1; at which time the light went on, the fan started running, the turntable started turning, and I heard a buzz and saw a miniature lightning bolt inside the microwave (just like in the Frankenstein movie)....everything happened at once. but the food never got cold. I put the food in for another 2 mins; everything worked, but the food was still ice cold. Another 2 mins; everything was still working, but still ice cold veggies. What would cause this to happen, and what is in fact could be wrong with this almost brand new microwave? My thanks in advance for your assistance. Johanna.

    Thank you so much for your EXCELLENT advice. I was afraid of voiding the warranty, so I called Sear's for in-home Service (since the microwave is built-in). Diagnosis: It was a defective magnetron, and the technician fixed it that day.
    Thankfully, there was no charge because the magnetron is guaranteed for 5-years from the date of mfg. even for folks like me who don't purchase the extended warranty. My thanks again for your help...Johanna

Normally that aarcing is due to food particles or grease trapped in the waveguide. It will arc over and over until it is removed. The other, worse possibility is that the stirrer or magnetron has failed. If it'sd still under warranty, I would call the nearest Sears store for service. If you or a friend decide to work on it, we have *critical* safety & disassembly info at our site, which is linked at our listing here on FixYa: You can find helpful exploded view diagrams and order parts by entering your full model number (without the suffix) here: (the 3 is correct)

Determining the Age of Your Maytag Appliance

This advice applies to all appliances manufactured by Maytag. Determining the manufactured date of most appliances is accomplished by looking at the SERIAL NUMBER. On Maytag appliances this is determined by the following method:

The LAST two letters in the serial number identifies the date code.

Example: 123456FY

The 1st Letter is the YEAR.

A – 1978/2002

Our Kenmore model 721.80833500 tray jumps off its track. This has progressively gotten worse over time and now the little end wheel on the rotating arm has broken off. The microwave still works and still...

Found 2 possible solutions on the net. (1) Check the engineering change at a Sears store. They reengineered the glass tray and the narrow plastic band the tray glides on. Get the new items from Sears. (2) Cut 1/4" out of the narrow plastic band the glass tray glides on. Possible solutions that look promising.

You may be able to download the installation instructions from the Sears parts site.

Just enter your model number there.

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

On the resulting page, look to the right for the blue "View manuals" button. Click it.


That Sears-related site has many free manuals. While the manuals they list there are all free, they will ask you to register.

Many times, the owner's manual will have the installation instructions inside.

If yours is not listed there for free, you would have to order it through the
Sears parts site.

Since it's under warranty, they will replace or repair it at their choice, and if they replace it, it will be the same model or a "like model".

I'd ask them about it.

We see this a lot. The problem is almost certainly on the control panel, which we regularly repair nationwide for $39.95 postpaid.

This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.
