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.

Charcoal Filter

Part #8206230A
This Charcoal Filter traps grease from your oven's exhaust to help prevent it from entering the vent, which could cause damage over time. If the exhaust fan on your microwave is not working, you may need to replace your charcoal filter. This charcoal filter is located within the intake grille of your microwave, which will need to be unscrewed and opened to gain access to the filter. The manufacturer recommends that you change your charcoal filter every six months. This filter measures 5 inches by 5.375 inches by 0.375 inches. Be sure to measure your current filter to assure correct replacement. This product is sold individually. We recommend the use of gloves during installation to protect your hands from messy grease during your repair. You should also unplug your appliance at the electrical outlet or switch it off at the breaker. Using a Phillips screwdriver, unthread the screws securing the grill. Open the door and slide the grill to the left and lift it up to remove it. This will allow access to the filter so it can be either replaced or cleaned. Remember to insert the tabs of the grill into the frame and slide it to the right when you are done. To finish, shut the oven door and secure the grill with the screws.

Part #W10208631A
This Grease Filter is constructed of Acrylonitrile Butadiene Styrene and is used to trap grease and help eliminate odors from the exhaust air while cooking. It attaches onto the exhaust and is rated as easy to install. The part is 12 15/16" x 5 3/4", and comes in silver. Refer to your make and model number to ensure this part is right for you. If the exhaust fan of your appliance is not working, this part is the most likely cause. This part is sold individually, and it should be noted that many microwaves require two filters, so you may need to replace both at the same time by purchasing two of this part. You should consider gloves during this simple repair (which requires no tools) to save yourself from getting greasy hands.

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

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.

This top interlock support is a genuine OEM safety component designed for microwave ovens.

The support holds the interlock switch in place and provides a reliable latching point, allowing the microwave to function safely and efficiently. A faulty or misaligned support may result in the microwave failing to start, operating with the door ajar, or displaying error codes related to the door lock system. Replacing this part restores proper door engagement and ensures safe operation. Installation may require disassembling the control panel and should be performed with the appliance unplugged.

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

Unless you have a very comfortable background with electronics and electricity, I don't necessarily recommend taking apart a microwave. If you are very handy and are going to be VERY cautious to follow the rules of discharging caps and testing voltages before moving forward, then go for it. That said, I took the microwave off and apart. Not knowing where to find the parts, I was fortunate that the installer put the instruction book for the microwave inside the front vent slot above the touchpad for reference. it details the location of every part and it tells you very clearly what each part you test should show specific to this microwave on your multimeter. Find this guide online if you don't have it. Turn on the microwave for 20 seconds with a glass of water to make sure it's not heating - that with the noise means it's eeither the magnetron, cap, or diode. Read the notes on this site for all of the basic things to look for with the magnetron, diode, and capacitor. Once comfortable with the guide, locations of those devices, and how to test, then take it down and apart. Unfortunately, I didn't do all those things in that order, and it only wasted a lot of time trying to find the parts. Once I found the parts and put all the screws and covers back for all the areas that didn't need to be accessed for the repair, testing went quickly. The diode was bad. Ordered a new one and had it in 3 days or so. That means your microwave will be apart and sitting somewhere for a little while until you get the part and have time to repair it. Putting the diode back isn't too bad. Reassemble the microwave and put it back up again. If i had to do it again, it would take me 20 to 30 minutes once the microwave was down and on a table. Also, I used some bricks with towels over them or you could use some sawhorses to keep the microwave elevated so you can plug it in and run it after installing the new component. Again, make sure you discharge the cap before touching anything again even if you didn't run it, but just plugged it in.
