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?
Answer 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. Read More... Answered by AppliancePartsPros.com | Thursday, November 14, 2019
