TECHNICAL REFERENCES: Troubleshooting Photo-Eyes

Neither photo light comes on...door opened this morning; but, will not function now. Have disconnected the door...it seems to be working properly. We had a power flux last night; which may have caused the problem. What do you think??? Thanks.

I purchased a Model 615 opener and had it installed through a local garage door company. A few months after installation it started having false-positives of an object in the door path and would not go down. The green light was flashing. I called the installer, and he came out and was able to get the emitter and detector aligned. Recently the problem has occurred again. A flashing green light on the emitter. Once again I am not able to get this aligned. In addition the door does not stop and go back up at the same point. Sometimes is is 3/4 down, other times 1/2 down, and sometimes a 1/4 down. Just recently it has begun stopping just after it starts. There is no rhyme or reason to when it will stop and go back up. Is there a way to test the emitter, receiver, and any circuit board on the system? This seems more like a hardware/firmware issue to me at this point.

Greetings, I'm hoping you can help me with a few questions/issues:

I opened my garage door, and when I went to close it, it beeped repeatedly. I checked the sensors, one is green, one is yellow. I tried cleaning the sensors, adjusting, eat to no avail. Weird thing, one was green, the other yellow, then after trying to re-align, I noticed the other was now green, and the other is yellow. Help?

Second, as I live in AZ, we had a monsoon storm roll in so I had to close my door. I used the emergency release and closed the door. Now the trolly is stuck in the "door up" position and I can't re-engage the trolly.

This may be due to the fact I tried to adjust the travel limits (it beeped 5 times when I hit the door button) The up worked just fine (without the door attached...my bad!) but when I try to adjust the travel limit to down, again it beeps several times without any movement.

I'm assuming I'll need to call support, but am hoping you might be able to help! Thank you in advance for your guidance!

The green photo eye blinks and is not solid. The red one is solid. I remember the green PE used to be solid. I can not align to make the green one solid. But everything else function correctly. Anything wrong?

If the operator is working from the wired push button control and the hand held remote control, the issue is with the keypad.  

When pressing any digit on the keypad, a backlight/illumination of the buttons should be seen.  If there is not a backlight, then the keypad does not have power.  Check for contact between the batteries and terminals or corrosion on the battery terminals. If contacts have been broken, the keypad will need to be replaced.  If there is corrosion, use a solvent or wire brush to remove.  

If power has been verified, return to the programming process.  After pressing the LEARN button on the operator (30 second code learning mode entered) enter a 3-6 digit code (pressing each digit firmly and in the center of the key) and press the ENTER button on the keypad, 2-beeps should be heard from the operator to acknowledge learning the code.  If the 2 beeps are not heard on first press of the ENTER button, try pressing the ENTER button more firmly and in the center of the button one or two more times.  If this works, there has most likely been some wear or damage to the contacts under the ENTER button and the keypad will work intermittently.  If programming fails, remove the keypad from the door jamb and repeat the coding process closer to the operator head.  (If there is RF interference, possibly from an LED coachlight, programming the keypad closer to the motorhead may help).  If keypad keys are glowing and the code learning process fails while the keypad is closer to the operator powerhead there is most likely a short on the traces and keypad will need to be replaced.

Keypad is WKCC and Opener is 2211-D

GZ,

What is the model number of your opener and model number of the keypad?

Door is fully operational but keypad doesn't work. Changed batteries. Even changed code after installing new batteries and still not working. Less than a year old. Thoughts?

Hi Stuart,

Please call 424-272-6998 for troubleshooting help.

I press the button and door goes 6 inches then returns. I have adjusted the force , I have checked the sensors , I have lubricated the system, and even if I hold the button down it still returns.

"Universal photo eyes" from HomeDepot will not work with a Guardian opener.  Guardian photo-eyes can be found on-line by seaching for GUAT-201 or GUDT-208.

Hi Terri,

It's best to call 424-272-6998 for troubleshooting help.

The motor beeps 12 times and the door will not shut. We followed the instructions for adjusting travel limits. When the down button is pushed after pushing the limit button twice, it only beeps and the door will not go down. The photo eyes are solid red and solid green and are not obstructed. What else can we do to fix this?

Can I go to home depot and get universal eyes?
I have the 600 SL the book calls for GUDT-208

Hi James,

It's best to call 424-272-6998 for troubleshooting help, but from what has been described, I supect a new circuit board is needed.

Garage door went up the other day and when pressing the button for it to go down I now get the twelve beeps. I looked and noticed that both Photo Eye lights are out. I tried adjusting them both but I get no light on either. Please help.

The PE with the red LED is the receiver and will illuminate when continuity is detected.  The green LED PE is the sender.  The green light will illuminate solid with continuity or flash when there is power but no continuity (alignment).  If powered up and the LEDs do not  illuminate (as you have described) and the door can be closed by a constant press of the push button (press hand hold for ~5s to initiate), the circuit board is not bad., the problem is with the photo-eyes and they should be replaced.

Hello I followed the troubleshooting guide attached here and I cannot get either Photo Eye's LED to light up. I moved both to the unit and plugged them directly in as the troubleshooting guide says to and still nothing. I have a Guardian 600SL, and using a multi meter I am showing 21.3v DC coming from each terminal. Any assistance would be appreciated... I am assuming I just need to replace the photo eyes but it is weird that neither the green or the red LED will light up (pointed at each other or not). Thanks!!

Hi Harris,

Yes, the GUAT-201 replacement photo-eyes are correct.

Can I use the 201 photo eyes for model 628? My red eye is not lighting. Green eye is blinking. I am thinking its a broken red eye.

Hi Mike,

It could be a stuck relay on the circuit board.  Please call 424-272-6998 for troubeshooting assistance.

The red and green lights are solid but when I attempt to close door it beeps repeatedly I tried holding down button but the same result no door movement

Hi Eric,

Please call 424-272-6998 for troubeshooting assistance,

Door open, wall and remotes give a 5 chime error code. Double press on limit to change to down, then pressing down give a 12 chime error. No remotes work while continuing to hold.thank you

Hi Edward,

1. Please be sure that all 4 wires for the photo-eyes have been inserted into separate terminals (in the terminal block in the motorhead).  Low current to the photo-eye causle be causing the green LED to flash.

2. There may be a chance that PE circuitry was damaged by a power surge causing the green LED to flash.  (PE would need to be replaced)

2. Call tech service (424-272-6998) for additional help.  Please have the model and serial number of your operator when you call.

The green photo eye blinks and is not solid. The red led has a weak glow. There’s no obstruction and I can’t seem to align the photo eyes. If I put the photo eyes closer, the red eye has a better solid. Do I need new photo eyes?

Mike,

The issue you describe is often related to a stuck relay.  With the handle of a screwdrive, giive the back panel where the buttons are located a couple of firm taps.  This could free the relay.  If this does not work, call tech service 424-272-6998 for more assidtance

I found my manual and it states door travels at abnomal speed for the 12 slow beeps but it doesn't say how to fix this issue. I also tried moving the door with the up/down limit set approach. The belt will move up but not down. hmmm...

Nigel,

Please call 424-272-6998 for troubleshooting assistance.

My garage won’t open or close when I use the remote and the push pad.

Hi Lee,

1. Most photo-eye (PE) issues are due to mis-alignment.  Loosen the wing nuts on the PEs and make adjustments until steady green and red LEDs can be see.  If this does not work, follow the process on the linked file to determine the source of the problem.

2. Staples will often, over time, cut through bell wires causing shorts and system malfuntion.  Materials will expand and contract with changing temperature, humidity and other environmental conditions, so an issue like this tends to happen more in the winter and summer.  Bell wire sould be replaced.

3. Your door can be closed by the operator by pressing and holding the push button control.  This is a line-of-sight overide in case the PEs malfunction.  All garage door openers have this function.  

Follow the steps in the troubleshooting guide to isolate and solve the issue.  If you have additional questions, please call a professional garage door opener technician or 424-272-6998. 

garage wont close, and I just notice one of the sensors is not showing a lights burn out? unit is about a year old and this is the first problem.

Drew,

That could be a possibility.  If your photo-eyes do not look like the photo-eyes on this link https://www.dropbox.com/s/and4hy1tif0z7ww/PhotoEye_white%20background_150402.jpg?dl=0 it would be the case.  Replace the photo-eyes immediately with Guardian photo-eyes GUAT-201.  The old photo-eyes will not be dependable and may not reverse the operator when the IR beam is broken. 

 Call 424-272-6998 to troubleshoot further.

Both eyes are green. Not one red & one green. Any ideas? I’m thinking old eyes were left from previous opener? Help!
