Photocell Problem

[JoeF]

yeah,
I took all the covers off, cleaned them and brushed out the housings etc.  All looked pretty clean and no signs of any water ingress.

Have you taken all the covers off the photocells and ensure there's no cob webs etc. in there?

I am having this exact same problem, the facc photocells on the internal side of the gate are clicking on and off every second or so... I have cleaned them out, taken covers off , and even placed the battery powered one right up next to the other. Still clicks on and off.... There is also a set of liftmaster photocells set up in series that monitor the outside. Those seem to click off completely {lose power) in time with the internal sensors clicking off.

Are the internal sensors faulty?

Hi,

Sounds to me that the set of cells (relay ones) are faulty. nuisance clicking usually indicates damage to the PCB of the photocell.
