Questions & Answers

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

1 Answer

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.

Kaffee, For a proper diagnosis, we would need you to please verify the model number from the units' I.D. tag since it will not come up for us as a valid model number.

The blower is controlled by a thermostat and does not turn off until the thermostat cools down to the prescribed temperature.

Jim for Model Number MMV4205DS2

My microwave is only 3 years old and the interior(cavity) bulb has blown out...the plate cover says only use 30 watts, but it seems that the 30 watt bulb isn't being made anymore....40 watt is now listed as the new part. Is that ok to use now? Also, when I opened up the plate to expose the burnt out bulb, there was a clear glue glob stuck to the socket and bulb, and the only way to get the bulb out was to scrap off the glob...when I called the help number at your web site, I now realize this glue was a type of silicon insulator. Is it still safe with out this gob of silicon on the socket? should I glue it back to the bulb socket or just put in the bulb and place the cover plate back?

Jim, The manufacturer has discontinued the 30-watt cavity light and replaced it with the 8206232A/WPL8206232A Lamp, Cavity 40 Watt, The higher wattage bulb will operate properly in your microwave. As for the "glob" of clear glue is "normal" The manufacturer applies a dab of silicone sealer to the socket and bulb for shipping reasons(Keeps the bulb from moving around so the filaments inside the bulb don't break). Once you remove the silicone glob, it doesn't need to be replaced, just install the bulb and check it for operation.
