Kitchenaid khms155lss4 microwave combo went dead what fuse should i check frist
Check to make sure you are getting power to the receptical, plug a lamp to confirm. Next unplug microwave oven and remove top, "several screws" now look inside where the keypad is, follow the wiring to the circuit board, there should be a small glass or ceramic fuse clipped in, before you take it out discharge silver rectangular capacitor with a screwdriver across the points to make sure all voltage is removed. Now unclip the fuse and test, if open replace with the same current rating, if no change I recommend a technician to take it further. Please remember there is extreme high voltage when unit is plugged in and running making it lethal, put the top back on for safety sake.
