YMMV5208WW0 Whirlpool Microwave - Instructions

Remove top grill screws [2] remove grill replace filter put back together.

Piece of cake. One screw to release the dropdown light diffuser. Just remember, the you're screwing the new bulb in from a reverse perspective. Also this site sends the correct part the first time.

I first unplugged the microwave. I then unscrewed the 2 screws from the top grill. I had to be careful because the grill was cracked close to each screw. It was a little tricky to remove the grill. Had to tilt it down as I removed it, and make sure the microwave door was opened as wide as possible. Filters were placed as the old ones, with the metal part up I believe. A little tricky to get one of the filters to fit. Grill was replaced with care so as not to further Crack it. Kind of maneuvered grill back in place, getting right side in place first. I noticed there were several tabs on the grill that needed to be placed inside of the microwave body while reinstalling the grill. Once the grill was in place, the 2 screws were put in to hold the grill in place.

mounted bracket, case closed.

Turn off power supply at breaker . Replace old bulb with new bulb .

We needed a phillips head screw driver to remove the single screw holding the light bulb cover in place.
Removing the old bulbs was a little work, because they had come loose from the sockets. We unplugged the microwave, so we could grip the sockets with a tool. I think my husband used a needle nose plier for this.
The new bulbs screwed in easily, and then we refastened the light bulb cover with the phillips head screw driver.

Unplug appliance. Remove total of 7 phillips screws from sides and front of bottom panel . Panel front drops down, remove one socket screw and socket. Now have access for lineman' s pliers to unscrew bulb base. Reinstall socket, replace bulb and 7 panel screws. Restore power.

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.

screwed in new bulb

Unplug the microwave. Then remove the six screws that hold the lower panel which has the light bulb cover and a couple of vent filters. The light bulb sockets are on a fixture that is connected by a quick connect electrical connector. Disconnect that and the whole panel is free to access the bulbs. My bulbs were very fragile and trying to twist them out resulted in the glass twisitng loose with the base still in the sockets. I needed to use a needle nose pliers to remove the bases and then I replaced the bulbs and put every thing back together

Replaced the supports and rack.

Husband replaced the bulb

Spouse just screwed in the new bulb and reinstalled the light cover plate with the two screws. Took under a minute. Works great.

Changed out turntable motor

Based on other similar posted repairs, I purchased the bottom switch. Upon removing the control panel to replace the switch, I found the blue 22 gauge wire was broken at the spade terminal. This wire had been crimped to the terminal along with a 14 gauge wire. Apparently the force to crimp the thicker wire weakened the smaller wire at the terminal. I stripped the end of the small blue wire and reattached it to the thicker wire using a solder iron and solder. The repair fixed the problem.
