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.

screwed in new bulb

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

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.

I had the help of a handyman, I'm 75 years young but not handy with tools

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

Husband replaced the bulb

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

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

Repair unsuccessful because they sent the wrong part, even after I questioned their selection. It is amazing how a company as large as Whirlpool cannot clearly indicate to the people who work for them how to order the correct part. The fault lies not in the individual who is putting the order in but with the company who cannot take the time to make sure that person is successful in completing their job. Will never buy a product from this company again.
As far as the shipping is concerned. It took forever, just to find out that the part was incorrect.
Better luck next time. right?

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.

removed perimeter screws from the bottom side and the lower cover is hinged at the wall side. Motor is visible and easily removed with two screws. Take of the old one, install the new one, and reverse the procedure to put the bottom cover back in place. Will nee helper to hold one side of the bottom until couple of screws can be put in on the other side.

took it out of box wooolaaa fixed thanks fast shipping too...
