Question about Home Security
I just had my springs replaced and now my chain is making a clicking noise on top of opener. I have checked all the internal gear and worm gear and they are not damaged. Have removed chain and reset on sprocket no change. More clicks on the upward movement, It appears the noise is coming from the area around the chain spreader. Door does go up and down.Any thoughts?

The problem lies in the RPM sensor, most likely due to the interrupter cup assembly. The interrupter cup assembly is the black cap that runs through the RPM sensor. You may have forgotten to re-attach this piece or it is probably moving too far out when the garage sets in motion. To fix this, remove the cup assembly, unscrew the two screws on the top metal piece with a 1/8 allen wrench, push the metal piece as far in as possible and put the screws back on. This will give more room for the cup assembly to spin and be read by the RPM sensor. Hope this helps!

2 flashes is a safety eye issue, but you problen is most likely that the chain is not sync with the limit setting. Take the bottom off the gear and sprocket assemble and rotate center limit srew until it is in the same position as the trolley.

Remove the chain from the sprocket and then run the motor until the sprocket turns clockwise and stops. With the door in the closed position and everything attached to it, replace the chain and tighten. This will get everything back into sync. You will most likely have to tweak the up and down limits a bit. Do not over tighten the chain. It should sag just a little.
