Door opener problem

Then they aren’t safety sensors?

These safety sensors are the major cause of problems with the 6 overhead doors I own. They are easily knocked out of alignment, fooled by the sun or fouled with insects. As a result, I also have mine mounted in the rafters above the door.

Yes, this defeats the purpose and they are no longer safety sensors, as the "safety police" here will tell you. Personally, I don't care. I like the fact that I can close the door and walk out of the building without tripping the dam things.

At my age, I have no kids, pets or family members with kids to worry about. I have the close force set so you can let the door close on your foot without pain before it reverses. If I squash a rat or mouse, so be it.

I'm not saying these sensors are useless. I would have them in place if the situation warranted it. YMMV.

I’m not sure how long I’ve been a homeowner with a door opener but maybe 30 years. I’ve had problems with the door sensors maybe 6 times or less. Usually because I bump them. It just takes a minute to realign them.

Exactly, ive had 1 known problem with door sensors on my house in 29 years. Have 4 sets of door sensors. Had to replace a set that went bad.

They may be sensors but not safety sensors the way you installed them.

My point which was denied. Perfectly useless that way. Might as well use a jumper on the circuit board.

Had a call the door would not go down… they had not used the door for months…

Nice spider with web tool up residence and once evicted problem solved.

Yes, they are useless mounted that way.

The manufacturer of my doors makes defeating the sensors nearly impossible. There is some sort of "handshake" between the main circuit board and the sensor that is difficult or impossible to defeat with a jumper.

The manufacturers use ohms resistance as a “test” for the safeties.

I do have a package of resistors in my glove box……for testing/temporary service. I’ve had the resistor “die” but the sensors still work. New safeties are still ordered because my resistor isn’t “factory”.

Interesting. Do all the major brands do it that way (Genie, Chamberlain, Craftsman, etc)?

Do you know the range of test resistor values that work?

I’m almost 100% certain they all do.

I’ve seen as low as 5k to a tick over 10k.
