I had installed one of the Home Depot motion detector lights about 3 years ago and it worked fine until recently when all of a sudden it would not come on except in "TEST" mode. I assumed the circuits were dead so I went and bought a new one with more or less the same features.
Well new one is installed and guess what, no lights except in test mode. I can turn the light switch off/on several times which is suppose to force the light on, no go. Set it to 2 hr., 4 hr., no go. Set the sensitivity High, Med, Low, no change. Seems nothing will make the light come on normally.
As far as background light goes it has not changed since the first unit was installed. I even placed my finger over the photocell to see if I could force it "dark" but that made no difference either.
Suggestions?
