Question about Kenmore Microwave Ovens
I have the Kenmore 81682 Over the Range Microwave Oven. Two weeks ago it stopped heating. I opened it up and the magnatron was cracked in a few places. I located and replace the magnatron (part number 2M289-M47) and it works without an issues for about a week. Today, it stopped heating again. I opened it up and the magnatron is cracked again. Before I replace the magnatron again, what else can I check? What would be causing the magnatron to fail?
The outer door frame CAN be replaced if you like. You can view an exploded view diagram at searspartsdirect.com. Just type in your model number and locate item 10 under the "Door" parts listing. The part comes in various colors so make sure you select the correct one.
The door can be easily removed by opening it all the way and lifting straight up at the hinges. The door will come off the hinge pins and can be laid on a flat surface for easier access. Place a layer of towels under the door to prevent damage to the door.
You will need to remove the door handle to get the outer door frame off. To access the door handle mounting screws on MOST microwave ovens, you have to remove the inner door panel that goes around the perimeter of the glass. You can use a small screwdriver to carefully pry the plastic up and work your way slowly around the perimiter of the glass. Most microwave ovens also have grooves in the panel that you can insert the screwdriver into. Use care not to pry against the glass. The glass is tempered and also has an RF shield that prevents harmful microwaves from potentially harming the consumer. If you break the glass, you may need to purchase a new door.
The door handle screws are located behind the inner panel. Remove the door handle and and locate any screws that may be securing the outer door (front) frame in place. Once you install the new outer door frame, re-install the door handle and carefully re-insert the inner door panel. Gradually work your way around the perimeter of the door glass and make sure it snaps back into place.
If you have questions about this repair, please let me know. I hope this helps you.
To answer your initial question, the microwave should continue to be safe to use as long as the inner door seal and door glass are intact. Make absolutely sure you reinstall the door components back together properly. Not doing so will render the oven unsafe to use. Refer to the web site I provided as a reference for how the door components go back together.
NOTE: This part is listed a bit cheaper at appliancepartspros.com. Use the part number from the first website I mentioned as your search criteria.

Most Kenmore microhoods use a 3" by 10" exhaust duct. Check for correct demensions. Make sure that the existing vent is this size or that you have room to adapt to this size. There should be a damper mounted to the top of the micro which will attach to the vent duct work. You will need an outlet in the cabinet above the micohood. This should be on a circuit of it's own. The microhood should have a wall plate for the back wall. I'm going to assume there are no templates available. Hold the wall plate against the back of the micro to determine the height placement in the opening. Most install centered under and against the cabinet above. Not all do, so this will confirm. Mount the wall plate to the existing wall studs with at least 1/4" by 2-1/2" lag bolts. Bore an 1-1/4" hole in the right rear corner of the cabinet above, about 2" out from the back of the cabinet and 2" in from the side, this is not a critical measurement, it is to pass the electric cord into the upper cabinet. There are two screws that support the front of the hood. I believe they are 1/4" by 3-1/2" long. If not included, check for size. The hardwae will have them, get flat washers to fit both also. Measure from the back of the micro to the mounting holes in the top of the micro, include the wall plate in this measurement, they'll be about 10" out from the back and about 1-1/2" in from the edge, near the front, but check that measurement, they vary. Drill 3/8" holes in the bottom of the cabinet at these locations. If doing this alone, best that you move the range out. It's nice to have a helper at lifting time. With the plate on the wall and the holes in the bottom of the cabinet, your ready. Put the 1/4" screws and someting to drive them in the upper cabinet, so they'll be available. Lift the micro into the opening with the front tilted downward, hook the back of it into the bottom of the wall plate, push the cord into the upper cabinet, tilt the front of the micro up until you can start the front support screws. Start both, don't let go of the micro until you are sure that both screws are started and will support the front weight. Once you're sure, tighten both screws all the way and connect the vent. Steel tape is best for sealing up any leaks. Power up the outlet, plug in the microhood and put in the popcorn. Get a good movie and enjoy in your accomplishment. Congrats. PS: Make sure the roof vent opens when the hood is turned on, I have seen them stuck shut from grease build-up.
