Light Bulb - 40W

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.

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.

Mounting brackets are fragile and plastic support is easily broken

Replaced the intake grille. The grille should be removed prior to cleaning. The entire part is plastic and easily broken so that the two tabs for the mounting screws are shattered and will not hold the part in place. If one attempts to clean the grille using only a moderate amount of pressure with a cloth the fragile plastic will break . The part is poorly designed. When the vent is removed to replace the charcoal filter, one may discover that the grille has already been broken in a previous cleaning operation.
