The control panel seem to be ok but when trying to heat something at makes a loud humming sound. ???
Hello Frank and thank you for writing.
It certainly sounds like it could be a faulty drive motor PS237772 and/or a faulty stirrer motor PS237771 , you should check for signs of damage, and replace if necessary. We hope this helps. Please contact us anytime if you require further assistance.
Everything was working fine and then i’ll put something into hate it and now nothing heats
Hello and thank you for writing.
The most likely cause for this is a faulty Diode PS239740 or the Magnetron PS1019593. If you have a multimeter you can test them. The magnetron should have a reading of less than 1-ohm resistance across the two terminals, and an "open" circuit between each terminal and chassis ground. The diode/rectifier should have a resistance reading in one direction only, no resistance or resistance in both directions indicates a faulty diode. You will have to make sure that the appliance is unplugged before starting your repair. Be aware that the high voltage capacitor in your appliance may still retain a charge even after it has been unplugged. We hope this information helps. Please contact us anytime if you require further assistance.

Turned out the issue was easily solved by replacing a single, inexpensive fuse.
First off, UNPLUG THE MICROWAVE.
The fuse is located under the plastic grill at the top of the microwave. It's held on by two screws. Once you've removed the screws and taken off the plastic grill, you go to the right side of the mic
... Read morerowave and remove another screw that holds a small metal grill in place. Removing the small metal grill is probably the toughest part of this repair. You kind of have to rock it back and forth a bit to get it to release. Once that's off, you can get to the fuse. I removed the burnt out one with a pair of needle nose pliers. I also put a small piece of cardboard under the fuse when I did this so I didn't accidentally drop it into the innards of the microwave. I did the same thing when I replaced the new fuse. I then plugged the appliance back in and made sure it worked. Once that was confirmed, I replaced both grills.

Noted on partselect.com that someone else with this problem, found it to be secondary door switch. There are three door switches in this model, but online info noted that one of the three might feel "soft" (in my case, one switch clicked in a rather "jiggly" way, the other two were strong decisive clicks.) To access the door switches on
... Read more this model was the only difficult part. First use a torx bit to remove the two torx screws below the latches inside the microwave. This frees the latching part inside, that holds the door switches, which you will remove after you take off the control panel. The top grill has to come off before you can remove the door panel. Remove the screws above the grill, on the microwave top cover, The grill on this model is covered with a panel that moves out when it vents. After removing the two top screws, the covered grill vent slides left to remove. Be careful, as the sliding tabs are plastic. Wiggle and jiggle it, to slip it off. Below the removed grill, is a small metal grill with one screw in lower center. Remove that screw, and wiggle that out. You'll then see the one screw that holds on the control panel. Remove this screw, and lift the control panel up to remove. Again, go slowly and gently, as the bottom tabs holding the control panel in, are also plastic and easily broken. Lay the control panel on something, (I used the coffee maker) and pull out the wire bundles tucked on the left, that are attached to the latching panel. Wiggle the latching panel gently to lift it up off of it's plastic tabs and pull it out towards you, so you can see the three door switches. Each switch (part number WB24X829) has a little black switch on it. Feel each switch with either your finger, or a screwdriver to see which one doesn't "click" strongly. The weak one is the one you will replace. The door switches are fitted into a tab, and plugged into their wires. Remove the defective switch, pull out the wires, and replace it with the new switch, plugging back the wires, and slipping it back into it's plastic tabs. Then put everything back together in reverse order. The entire job took me fifteen minutes EXCEPT for figuring out how to slide off the upper grill, which I have told you. A repairman would have cost $150, the part was $18. AND, there's a good chance, the other two switches will get "used up" in the next year or so as well, so I'll be ready next time. Thank you, Partselect, why work all day, to make money, only to give it to somebody else, for fifteen minutes of work. All I needed was the knowledge.

First I unplugged the microwave. :) Then, I removed the 6 screws found underneath the microwave, which allowed the bottom piece to hang down so I could see the turntable motor. I took the two screws out holding the motor in place and pulled the electric connectors off the motor terminals. Then I got the new part from PartSelect.com, repla
