I may be able to help you or a friend troubleshoot it, but I would need the FCC ID number from the model tag to look it up.

FixYa doesn't always notify us of follow-ups, so feel free to contact me directly (see below).

It could be an issue with your control board, and I regularly repair these at an affordable cost.

Your model's owner's manual (download here) does not mention it, so you cannot adjust or turn off the bump with the controller.
You would have to remove or disconnect the beeper, which would involve disassembly. More on that in this video.
Got more questions? Please contact me directly for full details since FixYa doesn't always inform us of follow-up questions. Remind me of the full model number and FCC ID number from the tag and your detailed symptoms.

Could be an open internal fuse, magnetron, or controller failure

Remove outer cabinet. Identify the bad switch in the latch assembly. The microswitches are held in by a plastic tab. Remove the electrical connections and note their location.Carefully push tab aside and the switch will pivot on one of the mounting holes. Be careful. The plastic tab can easily be broken if you use excessive force.

Could the "grinding noise" be arcing? If yes, then the problem could be the Magnetron.The Magnetron can be replaced but at approximately $75, It is rarely worth the effort. It will be at least twice that amount to have a repair shop do it.

unplug it for 12 hours or more and try again. Failing that the button or circuit for it may be broken, also make sure nothing is blocking the vent or nothing in the vent assembly is damaged. if you are opening the microwave make sure you know what you are doing of get a pro to do it for you. get an estimate and compare that to the price of a new one. Especially if the microwave is old or cheap.

When platter doesn't turn, food will not cook evenly. The motor must be replaced. No harm will come to the oven if you continue to use it.

Check those 3 micro switches in the door latch assembly. A bad microswitch can blow the main fuse. This usually ruins the microswitch.

Why do you need to "reset" the microwave? The is no reset for a microwave.

Kenmore... | Answered on Nov 15, 2017

Hi, you must check the inside fuse. If is burned out, please consider that something happened, you must check further beyond to find the causes.

it's the touchpad, you have to stick a new one, call a technician or buy the touchpad corresponding to your microwave oven model

Most of them you do have to carefully pry. You look on the inside of the door and you will see the choke seal. It runs around the whole outer edge on the inside of the door. Take a butter knife or a small screw driver and start to pop it up and out of the door. Slowly work around the door until it is completely free. Once you get that out you will see the door hook and will just have to look how it is mounted into the door. There will be a spring attached to it to allow it to pull up and down as the door is opened and closed. Make note of where the spring is attached to the inside of the door frame. It will have to hook onto your new part and back on the inner door.

Is the arm (on/off) switch down into the tray? You may have moved it up during the clean operation and inadvertently shut down the ice maker. Your temps are perfecto.

TCP is "True Cook Plus" in Kenmore speak.
Here is a cut/paste of a section of the manual.

*CUSTOMIZING TrueCookPlus' You may find that you prefer TrueCookPlus® to cook your food more or less. TrueCookPlus " can adjust to your tastes - to cook your food hotter or cooler - automatically: Example Clear 1. Press the Clear button. (§H§ 1 2. Press the TrueCookPlus® button twice. 3. If you want less cooking time when you enter a TrueCookPlus code, press 1. This will decrease the time by 6%. 345 4.

Press 2 to reset TrueCookPlus* to factory setting default time. 6. Press the Start button.
I didn't try to clean up the copy
Hope this makes sense and helps.

Timing a known quantity of water to boiling is probably the best way to make routine comparative checks on the efficiency of a microwave.

You have done more than most folk would do and have done almost all an ordinary handyman can do. Microwaves are now so inexpensive it is hardly worth repairing them now.

Probably the new magnetron is short of drive. There could be a problem with the supply to the transformer, the transformer, the rectifier or the capacitor.

There is a limit to how many multimeter tests can be done with a dead circuit before the voltages must be checked while it is operating.

The transformer has two outputs, one low voltage for the magnetron heater and one high voltage to drive the magnetron. The high voltage output CANNOT be checked with a normal multimeter!
The maximum range of a normal multimeter is likely to be 600 volts or maybe even 1 kv but the transformer output should be at least 2800 volts and could be as high as 3500 volts.

A special voltmeter for measuring high voltages would be prohibitively expensive and even an eht probe to convert an ordinary meter is painfully expensive.
