Light Bulb - 40W – Part Number: 8206232A
$8.55

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 function of the tray is to hold and rotate food items while the appliance is in use to ensure the food is being heated evenly. This cooking tray is made of transparent glass, and may need to be replaced if the tray is cracked or broken.

Microwave Surface Light Bulb
★★★★★

(29)
Part #W10709921
This microwave surface light bulb (120v 25w) is an OEM replacement part used in microwaves and microwave/hood combos. It is one of the two halogen lightbulbs that are positioned on either end of the base of the appliance to illuminate the cooking surface. The light allows you to easily monitor the cooking/heating process. Over time the light bulb may burn out or break resulting in difficulty viewing the cooking surface, and increased chances of injury while cooking. To replace the bulb, unplug the appliance and remove the light cover/lens, to access the bulb housing. Carefully unscrew the old bulb from its socket to avoid breaking it and damaging the assembly. Inspect the socket to check that it is in good working condition. If both of your light bulbs fail at the same time, the socket may be experiencing an electrical fault and will need to be replaced. Install the new bulb by screwing it into the socket. Reattach the light cover and plug in the appliance to check that the light bulb is functional. Each light bulb is sold individually.

Grease Filter
★★★★★

(11)
Part #W10113040A
This grease filter, used in microwaves, can be located underneath the microwave. The filter traps grease from the exhaust air and removes it from the air stream. This helps prevent grease sticking to the inside of the exhaust hood. Please note that most microwaves require two grease filters and they are both sold separately. This is an easy replacement done by simply pulling out old filters and sliding in the new ones. For further instructions and guidance, refer to the manual provided by the manufacturer. Unplug the microwave from the power source before starting this installation.

This door interlock switch is a genuine replacement part designed for use in microwaves. It serves a critical safety function by preventing the microwave from operating when the door is open. Because proper operation of the microwave’s shielding and interlock system is essential for user safety, this part should be installed by a qualified service technician. After installation, the interlock switches and microwave shielding must be thoroughly tested to ensure the appliance meets safety standards.

DIODE
★★★★★

(10)
Part #W11256462
This diode, or high voltage diode, is used in microwaves. It is an electrical current control device that ensures power flows in one direction and not the other way. If your microwave produces no heat, heats inconsistently, or gets noisy, replacing this part can be the solution. The tools needed for this replacement are a nutdriver, pliers, and screwdrivers. First remove the microwave cover, then remove the old part by disconnecting the small thermostat. Replace with the new diode. Remember to use the diagram provided by the manufacturer for more instructions.

R Ceramic Fuse 20 A
★★★★★

(7)
Part #W11707984
If your microwave is not turning on it could be due to your fuse needing to be replaced. This part protects the microwave by shutting it off if there is an electrical surge. This fuse is just over an inch long, is metallic on both ends and ceramic in the middle. Before beginning this repair, unplug the appliance and wait a few minutes before starting. Remove the outer cabinet which is held in place with two screws. You will then locate the power cord which will lead you to the fuse holder. Determine if the fuse has blown. Using an ohmmeter, you should be able to figure out if it has blown. A proper reading is zero ohms, if it reads as anything else then your fuse has in fact blown. Simply snap the old fuse out of place and place the new one in.

Microwave Damper
★★★★★
★★★★★
(8)
Part #W10843943
This damper is an authentic OEM replacement assembly used in microwave/range hood combos. It includes the damper door and frame. It is designed to direct the flow of air through the vent duct, and the release of steam and heat from the appliance during cooking. Over time, the damper door and frame can wear down or become obstructed by food particles and debris. A faulty damper assembly will result in poor ventilation, uneven cooking, and excessive moisture buildup which can damage internal components in the appliance. Disconnect any wires or connectors attached to the faulty damper assembly and remove it from the appliance. Position the new damper assembly and reconnect the wires/connectors before securing it with the appropriate fasteners.

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
