Question about KitchenAid KCMS145J Microwave Oven
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.

To check the internal fuse. Unplug the oven, unscrew and take off the
cover, the fuse should be easily found in the back by the power cord.
It looks like a regular fuse but is white instead of clear glass
because microwave fuses are special. You'll have to measure it for
continuity with a meter as a result and be sure to replace it with the
same kind. (try finding them at radio shack) Hopefully there isn't
something more serious also.
Hope ya fix it!

Remove the front panel by removing the screws located on the inside of the door (note hold door inplace, since it is heavy and will fall out after screws removed). Unscrew screws located on bottom of plastic retainer (2 each) Remove tension spring. Note 2 are included right and left. Note color of spring on end, different springs for different door types, stainless, black,beige or white. Replace all in reverse order.

HI, this is an indication of a failed door switch. When the switch fails, the control cannot recognize the closed door signal. Simply replacing the door latch mechanism will solve this issue.
Replace the door latch assembly, asap.

Hi, it is caused by a blown 20 amp fuse in series with the Primary door switch.
CORRECTION: Most often the first attempt is to change, or adjust, the primary door switch, but components (20 amp fuse, 15 amp fuse and cavity thermostat) in series with the primary door switch are the culprit. Check and replace as necessary the 20 amp fuse, the 15 amp fuse or the cavity thermostat.

& Welcome to FixYa
problem is with the fuse or the high voltage transformer that is bad and needs
replacement. Replacing the fuse will cost you under $100 from a professional
and getting the transformer replaced will cost you around $200. As the unit has
very high voltage inside so we don't recommend that this should be done by the
user. Please get back to me if you have any other questions.
