I am not aware of any Sears store that sells parts directly, although some will assist you in ordering them on line using an in-store computer. I'd just go to the Sears web site.

If you need further help, I’m available over the phone at https://www.6ya.com/expert/david_29ad5d1dd86564b0

Hello Danielle Carter,

Fact is... you are not looking for a fuse...

You need t know why that fuse OPERATED (Blow'd)...

Before we start...
An annoying little known trivia about micro-waves...
If used for EMPTY or for softening single pats of butter
they will soon self destruct (eat themselves... burn-out... fail).

When they do... their "micro-wave-generator" (magnetron) will
consume much more energy and cause the primary (most likely solitary fuse to operate)... "blown fuse".

Would that you had included a model number... (but alas)...

Unidentified... indeed!

Looking up your own model number on eBay or better GETTING your REAL PART NUMBER off of your original parts sheet will allow you to shop for the VERY BEST PRICE.

Sears has an excellent reference library... but if you want the same part you can get everywhere else for the HIGHEST price
SEARs ($$$$) is (not) your place...
(3 estimates... always!).


Don't forget to get that SPARE FUSE...!

Happy hunting.

Check with SEARS because they have one of the greatest waranties.

usually when you kill the power and then when you put power back on the machine works it's the computer board that's bad.all you're doing is resetting the board just like your house computer,if something happens to it you shut it down and reboot it,that's what you're doing with the micro wave just rebooting the board.here's the funny thing about micro waves sometimes the part you're gonna change is almost the same price as a new micro wave so i would first check how much the board is,i went on sears and they have the board for 115.00 repair clinic for 235 part number WPW10216347 they don't make this model anymore but you can get a stainless micro for around 290 to 300 dollars and if you buy the same brand all you should have to do is remove the bolts up above that hold it in place and remove the micro wave and the same brand should mount the same way so you won't have to drill new holes or replace the back metal panel.if i were you i would replace the unit instead of the board repair clinic shows most of the parts for this model out of stock so it might be a while before you can get any parts for this model but this is up to you.good luck with your micro wave.one more thing when you were in there did you see alot of grease,this is usually the cause of no heat,the grease from cooking on the stove top gets into the micro wave and on the mag tube and damages it,if there was grease in there i would just replace the unit

Yes, take the rack out and recycle it. I do not know why these micro-wave company put racks in the micro wave ovens. You get some insulation on the inside the micro flaking off next the rack.


The mega-tron tube is a very high energy transmitter. The energy will come out of the top inside the micro wave oven in a wave guide. Micro wave energy that generation by the tube is high frequency into Gega Hertz. You have a metal tray in side the micro wave acts like a big capacitor it stores energy in form of heat the next you know it look like Marconi is putting on a lighting display.



Leave the wire tie on a loft of bread and put in you micro wave oven to defrost. The next thing you might see is a load bread burning, instant toast. ----The use of micro wave were invented by the British before WWII. The mega tron tube generation very high frequency radio wave and these wave struck an object 100 miles away some of this beam energy would balance back to a receiver-----You have Radar.... I wish you and your family well being and be careful of micro wave ovens it can burn from inside out. GB you...stewbison

Either the power board to supply the magnatron or the magnatron is defective.
Check or have someonr check the output of power supply. If ther is a hi reading, then change magnatron
