If it were me, I'd look for an LED bulb with the intermediate base, or I'd screw in an intermediate E17 to candelabra E12 adapter and use one of the commonly-available LED bulbs with the E12 candelabra base.

Recent; just began in the last year or 18 months.

I have an old GE microwave, probably 8 years old or older. It's mounted above the stovetop and it has two T7 appliance bulbs (medium screw socket) underneath, for illuminating the stovetop, which is electric with a glass top. I'm using 25-watt incandescent bulbs, because these are nice and bright enough to see what I'm doing when I'm cooking.
But these T7's keep burning out. Sometimes they last a couple months, other times only a week or two. They don't always burn out at the same time, but often they burn out within two weeks of each other.
What could be happening? Somebody please help me get back to cooking on the stovetop again!
If we can figure this out, then my recently renewed subscription will have ALREADY paid for itself by eliminating a major source of my stress. Thanks in advance...

The LED converts that urrent into light so even when the light switch is in the off position, the LED bulb is still glowing.

If there is current still flowing when the switch is in the "off" position then the switch is defective and needs to be replaced.

I see there has been some recent activity to this original post, so hoping it is still an active post. My problem is older because I have yet to solve it in a couple years. We have a Frigidaire Gallery microwave. When the two over-the-stove lights burnt out, I attempted to replace them with the correct bulbs (I’ve verified this), but when I push the button for the surface light or night light, I get nothing. I’ve tried a second set of lightbulbs, so it’s not bad bulbs - they work in another location. Any suggestions as to what is going on? We’ve lived without it working for so long now, we’re used to it and need to replace the whole thing at some point... it’s just a puzzle I’d like to solve... thanks for any suggestions...
