Question about Chamberlain 3/4-HP Whisper Drive Plus Evercharge Standby Garage Access System
The saftey reversing sensors appear to be installed correctly and wired correctly according to all the troubleshooting instructions. Both sensors have a steady LED light that is always lit up. So, when I go to close the door, it won't go all the way down. Sometimes it only moves 3"...other times it will almost touch the floor...but everytime, it reverses itself all of a sudden. There is nothing in the path either. But when I do put something in the way of the sensors, it instantly shows an "obstructed path" message on the Door Control screen.

Check that the wheels and bearings are turning freely and that the door is not cocking to one side when closing. If the wheels are catching because of bad bearings, because the tracks are out of true or because the door is not staying straight in the tracks, the motor thinks that the door is hitting a car or a person and reverses. One thing to try: disengage the motor and try moving the door through the full traverse. Most automatic doors have a pull-cord that disengages the door from the motor. CAUTION: You may need a friend to help with the door, because it could be surprisingly heavy,.

SOURCE: My garage door attempts to close then stops and auto reverses. If I pull the release and manually push the door down halfway then press the opener, the trolley will make a full pass without any auto r
Look at the sensitivity adjustment, your description sounds like it is set too sensitive. This is the close sensor.

your chain is in the wrong position, unhook the chain and run the door opener so it is in the down position, then reattach the chain and make the adjustments as needed on the up and down screwes located on the side of the unit. good lick
