Question about Microwave Ovens
Wife cleaned and now micro button panel won't work. I let it sit 24hrs in case it was a moisture problem..No change.
Is it possible that some spray cleaner accidentally got into the controls?
Direct spraying of cleaners on the keypad and steam from the cooktop can damage the controls.
Always spray non-ammonia cleaner on a soft cloth (not a paper towel which can scratch) and gently wipe the keypad.
Always use the vent fan when cooking on the stove top to keep steam and grease out of the controls.
I always recommend that users spray the cleaner on a soft cloth (not on the keypad itself) then wipe the control panel off.
I recommend a soft cloth since paper towels can scratch the plastic.
Also, I always recommend non-ammonia cleaners since ammonia can crack and damage plastic.
Otherwise, the spray can get into the controls and lock it up or make it act odd.
If it does not dry out over time, it may need to be manually dried or blown out.
The keypad may be damaged or worn out, or control unit may be damaged.

If there is no heating please do not switch on unless you have confirmed the fault. It is possible that the Magnetron is faulty, the temperature cut off is faulty or the main capacitor is short. It is also quite possible that insect can get into the oven and create soft spots. When you switch on these will create a short and make the voltage jump and in the long run damage the magnetron.
So Remove cover after disconnecting , check for dirt/moisture in the cabin, if so wipe clean and dry, check the magnetron and area clean and use an jet air to clean off.
Make sure that the program controller is working if not check power - step down supply, the pads are responding- if not faulty pads- or the door switches, if contact is not through the microwave will not work.
Now keeping clear of the microwave, switch on, use a cup of water inside to test.
If you notice any sparks shut off as the magnetron or the main HT capacitor can be faulty. replace with same type.
If there is heating without any issues, you can use the microwave safely
