Photo eyes inop, opener still operates

I have a Sears HBW0777 opener that still works despite blocking the photo eye sensors. The lights stay green even when blocked. Tried to realign, no change. One of the lights just dims a little when blocked. It's an oldie but a goodie. I installed it about 14yrs. ago. I wouldn't worry so much about this but I have young children. Thanks for any input!

    I installed it back in '95. The eyes were part of a kit from Sears. The housing is black. I will go look at it to get more info off it tomorrow - too cold tonight - minus 16 and dropping.

    do not know this unit number. how old is it. what color is motor housing. may have add on eyes. standard eyes became law in 1993. If add on, they are not smart and that is one reason they stopped offering them. might consider a new unit for yur kids sake if eyes are add ons.

Dusk to Dawn Light Adapter


Might work. Might not. Depending if the eye can sense light and dark from that position. If area is shaded, then the sensor might think it's dark earlier in evening. If the area is dark, then sensor will not do as well, or might stay ON full time.
If the outdoor light shines on nearby surface, the reflected light might cause photo eye to blink on-off throughout night.. or not function as expected.
You can add separate photo eye to any light, and choose location for photo eye.

Check your IR door sensors. They are likely out of alignment. The can be adjusted by eye. Check that there is nothing blocking the light beam, even spider webs and debris can cause them to act up.
By pressing the wall button and holding the button the door will close fully even if the sensors are defective or blocked..

If the main light flashes 10 times when the door reverses it is a door sensor problem. Look closely at the green lights to make sure one isn't flickering ever so slightly. Tweak them a bit.

Sears Craftsman will open and close with wall mount switch but will not work with the remote door opener


Clear any obstruction from between the safety sensors. Loose leaves, trash, and dirt on the lens of the sensor itself are all examples of things that can obstruct the sensor's signal.
  1. Check each sensor for a steady glowing indicator light. If both indicator lights are on, or if one indicator light is flickering, the sensors may be slightly misaligned. To check for misalignment; obstruct the beam of the sensors so that they cannot see each other. When the beam is blocked, the indicator light on one of the two sensors will temporarily go out. This is the receiving sensor. Remove the obstruction and loosen the wing nut on the back of the receiving sensor. Adjust the receiving sensor until the green indicator light goes out, if not already out, then realign until the green light is bright and steady, then retighten the wing nut. This usually takes a couple of attempts before it is back in alignment.
  2. If an indicator light is out on one or both sensors, check for a possible loose or shorted wire. Sensor wires are attached to the white and black terminals on the back or side panel of the overhead motor unit. Check that they are securely connected to each terminal. Also check the wires for any breaks, especially anywhere they are spliced together.

I have two Sears 1/2 hp garage door openers. Cold weather problem


Very strange they both have the same exact problem. I would suspect something with the brackets is changing. When you are having this problem and the light on the receiver unit is not lit, tweak them a bit and see if it comes on. The odds of the logic board in both openers having the same thermal problem is just too high.

I have to hold the button until the garage door shuts, otherwise it will come back up and erratically blink, then it has to be reset. Thge part is a sears craftsman 41A5021-2F. Thanks


It does have to do with your sensors. Funny but I am having the same problem, but luckily for me I was able to find my manual. Look at the sending and receiveing units that are the protective "eyes" installed at the bottom of the garage door rails. One sould have a bright orange light (sending eye) and the other should have a bright green (receiveing eye). If either is dim or flashing that is where your problem is. The manual says to loosen the wing nuts and adjust the units up or down until both lights burn bright. If either is dim, it means there is an intruption in the wiring some where(my problem). Hopefully this helps.

One photo eye should be yellow and the other one green. The problem seems to be your down limit to be set too far. When you stand facing the door behind the operator the limit adjustments should be on the left hand side under the light cover. The down limit is the one closest to the door.

Garage Door Opener Lights


Some craftman operator don't have that feature. Are both photo eye lights green? Feature not available. If the photo eyes are yellow and green feature should be avilable. The operator needs to have a three button wall station. With the light on the operator off press and hold the "light" button for about a minute until the light flashes.
