My yard light won't go off any more. I block the detector wait 60 seconds and I hear the relay click off but the light now stays on when it used to go off. It clicks again when I block the detector, it times out and clicks again but the light never goes out.
Hi, Sounds like S.S. relay failed closed(short).
Wonderful. It near zero weather lately.
The (mechanical) relay probably has a contact welded. If you can get it open, cleaning the contact with a thin file or sandpaper might restore it, at least for a while.
If it clicks, then it doesn't use a SS relay.
Hmmm, Really? small relay controls S.S. relay gate. Mine does that.
te:
I would take the unit apart and locate the relay. If you can pry the cover off, you will likely find the contacts are stuck. I usually use an emery stick from my wife to smooth the contact surfaces when I run into a situation like this.
try to reset by turning of power,, if that wont work in daytime tap it with a stick- broompole, thats what I used to do with a stuck relay until it just would not unstick. Mine used to go bad alot, now I only use 25-50% of rated load for bulbs.
...then apply dielectric grease to the contacts to 'help' prevent future sticking and corrosion.
Did anybody mention frost or ice on the contacts? I took the assembly off the garage and took it down to my nice warm workbench by the wood boiler. At first it still was stuck on. Then I went and made myself a coffee and when I came back it was functioning normally. Simulate night time and it went on 1minute and off again with motion. Simulate daytime and it was off (before it was stuck on). I guess when it warmed up it started working again. Put it back on the garage and will see tonight what happens. Did not see any way to open it without a hacksaw.
