Questions & Answers

For Whirlpool 40W Light Bulb (Part Number: OEM13537968)

1 Answer

Hello James, Adding a toggle switch would be re-engineering the appliance so we cannot recommend doing this. If there are no wiring issues, the problem will be a stuck relay on the control board W11552018. This would be the safest, proper fix for the problem.

Hello Briget, This will have to be an issue with the control board W11342846 since it controls the voltage supplied to the bulb.

Brenda, The 8206232A / 4393681 Exterior Light Bulb 40 Watt is the "factory authorized direct replacement part". The light bulb manufacturer has "upgraded" the production ratings to 130V 40W. However, the microwave will still only produce 120 VAC, and the actual operating wattage will be lower because of the lower AC voltage. The ratings are within the "basic" manufacturing specifications/tolerances (+/- 10-15%) so there shouldn't be any unsafe issues when you replace and install the new light bulbs. Thanks,

Connie Yes, this light bulb is recommended by Whirlpool as a replacement part. There are two options for you: do not use it longer than you need to check something on the stovetop or take it to a local hardware store to try to find a light bulb for 25W.
