I checked the voltage on the bulbs that have been burning out in the oven;
they're 120. I found a 130 volt version on Amazon and will send for a coupl
e of those. I thought an LED bulb might last longer but I couldn't find any
I removed the dead bulb and screwed in the receptable/socket adapter. I fou
nd that the voltage at the socket varied between the extremes of 120-106 ov
er the course of a few minutes but generally hung around 112. I tried turni
ng on the oven heating element and the stove top burners to see if there wa
s any bleed-over of the higher voltage but that made no difference.
Digression: I was a bit concerned about the fluctuation in voltage so I tri
ed a few outlets around the house; they all had about the same range. Is th
is something I should be concerned about? Maybe I should check the breaker
box to make sure all of the connections are tight.
Back to the kitchen: Unplugging the stove, I checked the socket for defects
and found none. I did clean it out with a 12ga shotgun cleaning bronze bru
sh and bent the center contact tab up a bit to ensure good contact. After v
acuuming out the socket, I replaced the bulb. I noticed that it screwed in
much easier this time; maybe there had been some carbonization of the threa
ds or something in the socket.
Plugged it in and turned on the light; the new bulb lit. Hopefully it will
last for a while.
