Questions & Answers

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

1 Answer

Brent, the door switches would need to be checked after unplugging the power supply cord. With the switches accessed, the door would need to be opened and closed multiple times to identify if the switches are being activated by the door hook each time. If not, it is possible that the door is sagging and not closing properly. If the switches are activating every time, the failure would likely be in the main control. However, it appears a number is missing at the end of the model. If the model number could be verified and provided in a new question, this will allow the most accurate information to be presented.

Rodell, There does not need to be a ground on the light bulb and you simply just install the bulb.

Earl, this would be a main control failure. Unfortunately, the main control R0000349 has been discontinued by the manufacturer and is no longer available.

Mark R for Model Number WMH32519HZ3

I had a lightbulb burn out on the one that lights up the cooktop below. When my tenant went to unscrew from socket the glass separated from the threads and sparked. I was able to retrieve the male part of the bulb. Put in a new bulb and the light didn't work. I went ahead and ordered a new socket thinking the sparking may have compromised it. After replacing the socket, I tested, and the light still didn't come on. I checked the wires for voltage that attach to the socket and was getting 120v. I turned the light on and off at the touchpad, but the voltage remained on at the socket even in the off position. The display was showing the light on in the hi and low position but wouldn't light up the bulb. Do you think the main circuit board was compromised from the arcing that happened? All the other functions of the microwave work except for the surface light.

Mark, Yes, this would be an issue that when there was a spark it caused a problem with the main control board.

Paulette, the light bulb 8206232A will operate properly with the model provided as the intensity is controlled by the voltage sent to it from the main control.

Hello Tana, The problem is not the bulb when it will not dim. The control sends different voltages to the bulb for different levels of light. The issue will be with the board so to give you the proper part number for the board for your unit, we will need you to please post a new question including the complete model number of the unit in your home. There will be a digit after the "Z" that is necessary to provide the correct board. Thank you for your patience and understanding in this matter.
