Comments (66)The sunlight shouldn't affect it. I can't think of any way that it would. "I have solid green and orange LEDs, " But that doesn't mean that they are aligned correctly and the slightest vibration could throw them off. They can be close enough to make the LEDS light up while the door isn't moving. Watch the LEDS while it is closing and see if they blink. Use a string or straight edge if you have one that is long enough, or you can also use a laser level. Using a string is easiest to describe, so I will use that example. I hope you can figure out my instructions! It's easier with two people but if you are doing it alone. Tie the string below one sensor and pull it over the top of it, then over the top of the other sensor. The string should lay flat across both. Adjust if needed. Then tie off to the side of one and pull across the other and adjust that axis also. Repeat step one in case the adjustment moved the other axis. I hope this helps....See MoreSears Garage door opener problem
Comments (33)I've been reading quite a few posts regarding issues with the Craftsman openers and wondering to myself, was it a smart way to go? I guess hind sight is 20/20. So, Christmas '07 we purchased a Craftsman 1/2 HP garage door opener as a gift for my mother-in-law. Less than 1.5 years later we're experiencing the same symptoms as schneider-rolfo. Door will not open or close or make any noise whatsoever when using either the remote or the hardwired console. The remote stopped working a few months ago and replacing batteries didn't resolve. Now, neither console or remote do anything. I noticed that one of the sensors' LEDs will not light regardless of alignment while the other is working (I don't recall if it's green or amber, but know that it is lit.) Could the issue be caused by a faulty sensor or might it be something else more serious? Sears, who did the install, wants $65 just to come out to diagnose the problem and I'm sure it will be more to have them fix any issues as the warranty on these I've been told are only 60 or 90 days. Any thoughts before I spend the cost of a new opener to get someone out to look at and repair it? Thanks....See MoreSears Craftman Garage Door Opener Problem
Comments (7)Cold weather affects the receive unit of older Craftsman garage door sensors. You've tried tweaking the alignment. You've checked the connections. Everthing is as it was when it worked but now the weather is cold and the garage door won't close. The green light on the receiver is off. You've tried warming the sensor with a hair drier and it miraculously woke up after a few minutes of gentle heat. Well, are you ready to fix this thing or replace it? Let's fix it. Remove the clip on wire and unscrew the sensor from the bracket so you can hold it in your hand. Notice the seam that runs lengthwise along the unit. Using a sturdy blade such as a carpet cutting knife, score the seam several times being careful not to apply too much pressure or cut yourself. Carefully pry the shell into two parts. Be careful not to lose the lens when separating the pieces. Gently lift out the printed circuit board. On this board are two electrolytic capacitors. One is 470uf at 10 volts. The other is 1uf at 50 volts. (Probably only the 470uf part is bad but I replaced both capacitors because I don't like doing the same job twice). Go to Radio Shack or your favorite parts supplier and buy replacements. Solder them in observing the correct polarity. The board has a plus sign near the hole through which the positive side of the capacitor goes through. If you are unsure how to solder the parts in, find the nearest geek on the block and pay him a few bucks to do it for you. Put the two halves back together and use black electrical tape or whatever you've got (no duct tape pleeez!) to hold it together. Plug in the cord and mount it back on the bracket and tilt up and down until the light comes on. You are in business again for about 5 bucks worth of parts and a little of your time. Alternatively, you can buy a new set of sensors for about 30 bucks. RE: Craftsman Garage door opener One last post: I took the old capacitors to work with me and put them on a cap checker. My suspicion was correct. The 1uf capacitor was still good and the 470uf capacitor was bad. So you don't need to replace both unless you really want to. Just replace the 470uf capacitor and your repair cost has now dropped to about 2 bucks worth of a part and your time. PS: When you tape the two halves together, run the tape lengthwise along the seam, one piece on the top and and another on the bottom. The mounting screw will keep the halves together. You just want to keep the dust out....See MoreDifferent Craftsman Garage Door Opener Problem
Comments (16)Hey guys, My Garage Door Opener(Craftsman 1/2 HP) only closes the door halfway, then bounces back. I pulled the trigger to manual, closed and opened door completely by hand once to make sure nothing block the rail track,also nothing blocking the door way, then switched back to auto, pressed the wall switch, it worked fine at the first try(closed and opened door successfully), but it closed half way and bounced back again at the second and third try, then stay that way. I noticed the light blinks few(2-3) times every 10 seconds on the opener box, I got same testing result no matter pressing on wall switch or remote. Is this have something to do with the sensor? please advise, thanks!...See MoreUser
