Chamberlain garage door opener . It works open and close but the senser does't work with obstacle
One possible reason. (RF) Interference from an ultrasonic humidifier. The radio wave created to create the mist will cancel out a garage door opener I learned it the hard way I almost replace two garage door opener's but I turned off humidifier and everything worked in my Internet works better now too. Just passing this tip on hope I helped.
What doesn't the sensor do with an obstacle?
SOURCE: Door will only close when held down
That normally happens when the sensors aren't aligned. Both sensors have led lights on them the yellow/orange one will stay on all the time the green one will go out if it cant see the other sensor. Possibly theres a wire that's broken or the other sensor is really out of alignment. Check every inch of wiring from the sensor to the opener, remove wire nuts if present and check the connections. The wires that are used are small, solid and can break easily. Also see if there's a staple that's too tight, move the wire abit where it's stapled and look for damage.

Okay...upon further inspection, my left spring has broken in two. Going to call around for some quotes to replace the spring. Thanks for the suggestions.

The sensor eye - or more likely, the other end, the sensor light - probably got knocked out of alignment. The eye should have an LED on it - possibly one that glows green when it's ready to close or red when it's obstructed or out of alignment. Try adjusting the light until the LED on the receiver glows green.

check that lenses on safety beams are clean and that they are aimed at each other so that both have led light on.

First, check the safety eyes. There should be a light on each eye that is on. If not, realign the eyes. If that does not work, check the force settings. They are the blue adjustment screws. They should be set on 4-5. Do not go above 6 or there is a problem with either the door or opener, or both. If this does not work check all of the wiring on the back of the opener. 1 should be a red wire, 2 should be three white wires and 3 should be two black wires. Check the wiring to the wall button. the back of the button indicates red and white screws. To take off the wall button you will have to remove the big white button if you have the "deluxe wall control" If this does not fix it, respond with more info on door position and what happens with remotes and wall button.
