Light Bulb - 40W – Part Number: 8206232A

Light Bulb - 40W
★★★★★
★★★★★
(177)
Part #8206232A
This 40w light bulb is a replacement bulb constructed of glass and metal. It is an easy-to-install electrical part which produces 40w of light. If the bulb won't light up then it may be broken and should be replaced. The bulb attaches directly to an appropriate light socket and has a small screw-in base. To access the exterior light bulb, you will need to remove the panel on the bottom of the microwave using a Phillips screwdriver. If your exterior light bulb has not been changed before, it is probably held in place with some silicone. You will need to cut away this silicone to remove the old bulb. If you cannot access the silicone with a utility knife, it can be removed using dental floss. Once the silicone is removed, simply unscrew the old bulb, and replace it with the new one. Be sure to disconnect the power to the microwave before you begin this repair. This light bulb measures about 1 1/8 inches. We do not recommend using a higher-wattage bulb for this appliance, and can only recommend this specific bulb. If fixing the bulb does not solve your microwave light issue, it's possibly a problem with the socket, which means the socket and/or board will need to be replaced. This can be a more dangerous repair, so consult your user manual or a technician before attempting.

The nightmare was that this microwave is installed under the cabinet....in order to get to the light bulb I had to pull out my stove then squeeze into the space between the stove and counter....my old microwave light bult was much easier to change.....Shame on Whirlpool for making this so difficult.....must be a better way to cover the li ght bulb so that we do not need a screwdriver to remove the door to get to the light bulb

Microwave worked intermittently depending on how door was closed

  • Robert from Bainbridge Island, WA
  • A Bit Difficult
  • 30 - 60 mins
  • Pliers, Screw drivers
Remove top grille (2 screws), undo control panel (1 screw). Tilt down control panel, switches are on the left. There are actually three switches that are involved with the door, two horizontally mounted, one vertically mounted. This would be an EASY REPAIR, but it took me a while to figure out which of the three switches was bad, and a lso took a while to figure out that there is a plastic rod that inserts through the hole in the switch body. Once i figured this out went like a breeze. Lower horizontal switch was the bad one, but since the kit came with two switches i went ahead and replaced the upper horizontal one as well. IT appears that the horizontal switches are probably more likely to fail than the vertical switch based on the position of the switch and force angles. Works great now!
