Genie Photo Cell Troubleshooting
The following is a list of things to help troubleshoot the photocell
circuit and order parts if necessary:
1.) Unplug your opener & plug it back in. This action may reset them.
2.) Using a screwdriver, "short circuit" the two screws on the red
light photocell together. This may reset them.
3.) Inspect the wires running from the opener to the photocells for
breaks or loose connections.
4.) Clean the photo cell lenses of dirt, cobwebs, etc.
5.) Unscrew the wires to the photocells at the opener, remove the
photocell modules from their brackets and wire them together with a
short set of wires, approximately one foot long, directly to the
opener. If they work correctly replace the existing photocell wires.
If they fail, check for voltage (12 volts DC) across the photocell
terminals with a multi-meter on the DC scale. If power exist, replace
the photocell modules. If no power exist replace the main sequencer
board in the operator.
