How to Troubleshoot & Replace Whirlpool AP4512653 / 8206232A 40W Light Bulb

I easily found the correct part on ApplianceParts Pros.com. ordered it and received it in 2 business days. the bulb fit perfectly. 

I couldn't find the light locally so I went to the whirlpool website and this is one of the sites that came up. I ordered the light and received it in a few days and it was the correct one. So all is well and I would definitely order from this web site again. Thanks!!! 

I managed to uninstall the bad bulb by turning it counterclockwise by hand. When the new bulb arrived, you can imagine my elation. After quickly reviewing the instructions, I decided to go my own route. I looked over the receptacle and figured out my course of action. I put the new light bulb in the hole, but this time i turned it clockwise. After about 4-5 turns I felt the resistance in the threads and figured I should stop before I break something. Then came the moment of truth. I hit the "on" button on the microwave and the light lit up! Project complete! Thank you appliance parts pros! 

We looked everywhere locally but we could only find 25w bulbs which were not nearly enough light. Finally we located the bulbs at AppliancePartsPros.com. I placed my order and it arrived within 24 hours. Amazing service and I was able to get extras for stock as well as an extra for inside the microwave. Thank you! You have a new customer.

After looking online and finding reports that the bulbs at big box stores wouldn't work, I found this site. I read the reviews and decided to replace both lights and filters. Parts arrived and are working great as I expected. I'll keep your website handy for all future home repairs.

In order to get the bulb screw base out of the socket I had to remove the bottom metal panel and remove the the bulb base. Once I removed the socket, I noticed that the one of the electrical solderless connectors was corroded and burned. I replaced the connector, socket, and bulb. Works great now. 

Ordered 2 boxes of bulbs at 5pm on line and FedEx delivered them 9am next day. The bulb is non-standard size and wattage, and not readily available in my area of central Illinois. I found them online at AppliancePartsPro a couple years ago and keep a supply on hand. It is a simple fix to remove the Phillips screw holding the glass lense, remove dead bulb and install a new one. The very first bulb change was a challenge because for reasons unknown to me, Whirlpool elects to apply a glue or cement to the bulb's threads, perhaps to influence a person to call in a technician to remove it. The owner's manual cautions removal because 'it may damage the electronic control' but the control panel will display 'on-high, on low or bulb off' so pressing bulb control button until OFF appears eliminates any problem of damage. In a first-replace situation, if the glass breaks or comes out of the base (as mine did) simple grip the remaining base with a pliers and screw it out of the socket. It may turn out to be an 'Olympic event' to bend and reach to the bulb chamber with the range in place and still try to see what you're doing (especially with bi-focals). If removing the base with pliers causes the base to bend and distort, no problem - you don't need it anymore anyway, and the bending will help loosen the grip of the cement holding it in place. 

Fortunately, appliance parts always have what I need to replace older and newer model parts. My requests are shipped via FedEx within a minimum amount of time to complete the task at hand, there's never a need to drive to several brick and mortar stores to complete the project. This time, only a light bulb for the hood of my microwave was needed and this company didn't disappoint.
