This should be a 1 minute repair. However, there are a few issues. First, make sure you order the correct bulb. Mine is a halogen push in bulb, but the parts list showed a screw in bulb.
Remove power from the unit OR be sure that the light is turned off with the push switch.. The display will show the status as you rotate through the dim levels.
There is a single Phillips head screw holding the cover on the underside of the over stove microwave. carefully remove it. When loose the panel will drop down and you will find the old bulb in the center of the front of the opening. Remove the bulb. Now the important part. Carefully unpack the new bulb being careful to not touch the glass with your bare hands or fingers. Then insert the bulb into the socket.
If you unplugged the unit then plug it back in and push the switch to check that the new bulb works and is in the socket, then turn it back off.
Carefully lift the cover back into position and replace the screw. This is the hard part as you are working upside down and can't really see when it is lined up properly. When you have the screw back in and tight you are done. Press the light switch to enjoy your lit up stove again and put your tools away.
If you get your fingers on the glass bulb then clean it off with some rubbing alcohol and a paper towel to remove any finger oils before you put the cover back in place. Finger oils can boil with the heat of the lit bulb and cause the glass to explode. This holds true for any halogen bulb.

Part of the support was missing. I had to remove the two switches and put them in the new bracket
Had the switches reversed and started blowing fuses. Reversed them and changed the fuse and it started working.

Unscrew lens and direct access to surface light cavity. Removed old light bulbs and replaced with new bulbs. Reassembled lens cover and turned lights on successfully. Took less than ten minutes.

Just opened the door and dropped in new part and viola!

Used a philips head screwdriver to remove one screw holding the light cover. Pulled out the old bulb and inserted the new one. Replaced the cover.

Removed the old turntable tray, replaced it with the new one.

Replaced bulbs easily.

On top front of the microwave are two Philip's head screws holding the rail on. Remove these screws and the rail snap out the old filter (noting the dark side down) then snapping the new filter in. Replace rail. 10 to 15 minute task.

Remove the two screws to the plastic vent strip at the top of the unit. That exposes a metal cover (upper right) held in place by two more screws. (Found that removing the screw holding the key panel in place and moving that out of the way made for more work room) Remove the metal cover. The HV diode (visible) on one end is secured to the chassis by a screw. The other end is fitted to the HV capacitor. So unscrew one end and pull the HV diode off the capacitor. The replacement fits on like the old one came off. Very simple repair. But it would be safe to short the capacitor terminals to the chassis first. Noticed that it appeared the sparking was caused by the HV diode's outer casing being worn by the asbestos covered wire next to it and laying against it. I made sure the two were not touching, before putting the covers back on. Also, the problem started with an occasional spark when the MW started. It quickly deteriorated to a full, non-stop electrical sparking. You can hear it, smell it, and see it through the top vent. You don't need to remove unit to work on it.

After removing the over-the-range unit (no small feat!) I had to figure out how to open the case (good puzzle!). Capacitor had already discharged, so it was very easy to reach in, pop the old fuse and install the new one! As per your advice, I found out I was a "28%-er"! Upon re-installation, the microwave "sprang to life"!! Thanks, "Part Select"!! I was already shopping around for a new machine! (Now if you could only tell me an easier way to re-mount this heavy beast over the stove!!!)

Loosened but did not remove screws that held up microwave over range,removed grill on top by loosening screws that held grill in place.removed small mesh grill on right side of microwave, this gave me access to capacitor ,diode is connected from one lead of capacitor to a metal plate ground,Disccarged capacitor to ground by shorting terminals to ground using a thick insulated screwdriver.Since the diode was screwed to the top of the metal plate I cut it out with a pair of side cutters .I then connected the new diode to the capacitor with my long nose pliers and groonded the other end to a more accessible part of the metal grounding plate.I then replaced all parts in reverse order.Works like a charm.
