hello! We have a 1/2 horsepower Sears power garage door opener. The garage door goes up okay, but it won't go down. We sprayed silicone and greased the wheels, wheel track, chain track (it's a sectional garage door) and still nothing happens. When we push the button for the to door go down, at first nothing happens but the lights blink about ten times. If I hold the button in, the door will go down until I release the button, and then it will stop and and reverse itself and the door goes back up. If I hold the button until the door is all the way closed, I have to release the button at just the precise moment for the door to stop, or it will go all the way back up again. I've adjusted the power on the main unit to give it a little more power and on the other side of the unit I adjusted the screw so the traveling is a little stronger on the down side.
Hi, it sounds like it is with the The safety reversing system.When the invisible beam path is obstructed or misaligned while the door is dosing, the door will reverse. If the door is already open, it will not dose.The opener lights will flash 10 times. (If bulbs are not installed, 10 clicks are audible.)Different models can be different on adjusting, so I will need to know the model number to give exact instructions.
Hi, having WiFi issues, please be patient with me. I am looking for you.
Hi, as far as a sensor problem... Remember one of the sensors little green light will go out when obstructed and the other will stay on. If the light is flickering the sensors need to be tweaked a bit.
The proper way is start at the garage door opener and carefully check the sensor wires for staples or other damage to the wires. The next step is to close door, and with the lights out, check sensor alignment,... this is done by aiming the sensor in the general direction of the receiver,,, then moving the receiver back forth up down until the receiver light goes out,,, then setting the receiver in the middle of each range (up/down & back/forth).
Leave door closed and unhook trolley-operate a bunch of times and see if sensor lights dim or flicker or go out. If so check mounts and tracks or jambs for looseness.
As to need for more downforce, you should not have to pull door down hardly at all to close by hand. If closing is easy, and the opener (not sensor) lights always flash when it reverses don't worry about downforce. You should check how much resistance it takes to reverse monthly when downforce is set to a high level.
For some reason some downforce screws will creep with age, needing higher number to get same force.Also, make sure the entiregarage door opener is lubed right before you worry about a board replacement.
That is fine, I know how different formats can be. My problems still persist as well. I will keep trying and we can pick this up later if nothing gets better for either of us
