The main controller board, or one of the power supplies has failed and require to be replaced.

You should take the microwave oven in for an estimate. I strongly suggest to not service this type of appliance yourself unless you are trained and experienced in microwave oven service.

There are many safety issues when servicing microwave ovens.

Magnetron is probably faulty.

Many microwaves have similar issues. Usually, (not always) only the light is on and the fan is running, not the section that produces the microwaves. This problem can be caused by the door switches that are out of alignment or a defective control board.

The pads actually share some of the same lines inside the touch pad. There are silver oxide traces inside there. If a trace inside breaks, it depends on which trace breaks as to what pads dont work. If a trace that is common to say pads 1,3,5,7 you would lose function of those pads. 1.....2.....3.....4......5....... it is sort of set up like that inside wher eone connects to another and so on. So lets say a line between 2 and 3 breaks then you would lose pads 3, 4, 5 and any others on that same line. Will have to replace touch pad, cannot repair.

Most microwave diodes will work just fine from system to system. The most common ones I use are rated at 550ma. When you check your old diode what made you think it was bad? They are such a high rating you will not get a reading on it with a regular ohm meter. Mostly on HV rectifiers if it is not shorted ( Zero Ohms) it is probably good. If you have no high voltage then substitute it and see if you do get high voltage, then you know it was open. Follow the video and give it a try.

"F3" means you have a shorting membrane keypad.

I regularly repair these controllers and details are here.

If you have other questions, it's best to follow up with me directly.

None to my knowledge, but common faults include keypad failure (may show error code "F3") and cooktop light failure, both of which can be affordably repaired. (See link below)
