Oven Light Bulb Update
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 couple of those. I thought an LED bulb might last longer but I couldn't find any oven LEDs.
I removed the dead bulb and screwed in the receptable/socket adapter. I found that the voltage at the socket varied between the extremes of 120-106 over the course of a few minutes but generally hung around 112. I tried turning on the oven heating element and the stove top burners to see if there was 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 tried a few outlets around the house; they all had about the same range. Is this 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 brush and bent the center contact tab up a bit to ensure good contact. After vacuuming 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 threads or something in the socket. Plugged it in and turned on the light; the new bulb lit. Hopefully it will last for a while. Paul |

A variability _is_ an issue; if it is house-wide that indicates either a utility problem or possibly a grounding issue at the panel as an individual circuit or two wouldn't show up except on those affected circuits. -- |

The voltage going to 106 seems to be way low. Power comming to the house is by 3 wires. Across two of them will be the full voltage and from either of those should be half the voltage. If there is more than 2 or 3 volts difference it is time to start looking for a problem. Usually the neutral wire is loose if this is found at several sockets in the house on different breakers. If you could check several recepticals at the same time or with the same 120 volt devices turned on you may find some are at the 106 and some are around 130 or more volts. The total should add up to what ever is comming into the house on the 240 volt line. |

My current bulb is rate 120, so the 130 will loose about 20% of it's light and will be at 350 lumens (if I read this chart right http://www.mendipcavinggroup.org.uk/...s/occpub2.html ) I did fail to list the operating voltage. |

What worried particularly is the apparent short-term variability; that implies something is really going on; shouldn't see much fluctuation at all other than the very short sag during a large appliance or A/C motor start and that shouldn't be long enough to even be able to read the actual dip on a manual meter...just a quick flicker that would be visible. -- |
