Howdy, 2 options. A- UNPLUG the unit. Get up on a ladder if you can safely, and look at the lightbulb socket contacts. Sand or srape them clean, or replace teh socket if its all pitted. B-Or if you have a VOM and know how to use it SAFELY ON A LIVE CIRCUIT, check for 120v at the socket. I strongly recommend using option A!!! Good luck. Dave,

I was thinking the exact same thing, and I did fiddle with the sensors quite a bit. I can confirm that moving them causes the light on the receiving unit to turn off, and pointing them at each other causes it to become solid again. I am pretty sure they are pointing as directly as possible at this point. I suppose I could have a bad sensor, but I don't know how to determine this. There is no way to temporarily override them as far as I can tell. Unless I can confirm that, it seems pointless to spend the cash to replace sensors on a unit nearing its normal time of death. The other unit I was thinking of is about $220 (from Lowes), but I do agree that the warranty seems fishy. I'm guessing there is a lot of fine print and hefty shipping charges involved in getting repair work completed. It still seems like a better chance than the Craftsman 90 day warranty.

I would trim a pressure treated 2x2 to match the varying gap between the door and threshold and then attach it to the bottom of the door (after painting). This is similar to the process of trimming a new wooden door to match the contours of an irregular threshold.

It appears that neither light is over a table or counter top, so I would suggest semi-flush drum style for light fixtures that would be alike. For the dining table, another style could be used and hung so that it is about 35" above the table.
