Stop heating
Check the mains power to the microwave before you check for power to the unit. If the program controller is not working , check
power - step down supply, the pads are responding- if not faulty pads- or the
door switches, if the switch contact are not good then it will not trigger the
processor to switch on the waveguides. If the lights or fan work without any
display or action of program being triggered to start then it can be a possible
fault on the main board or the processor. Sometimes insect secretion can short
the board and display panel and so the processor can work in such an erratic
manner. If so clean, solder and reset the board. Now identify the parts by

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. Check this link to
know how a microwave works:

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. Check the wave guide covers, if food had deposited
then it must be checked or replaced. See link: http://www.espares.co.uk/advice/microwave/a/5/1146/how-to-replace-a-microwave-guide-cover.html
