Garage door wont close, Stops and Reverses, Voltage Test. 

Oh goodness, I can’t thank you enough. I’ve watched several videos, but none of them talked about checking the wires. You saved me from spending money I don’t have.

Best video I have seen on this subject. Mainly due to the accurate description of the normal voltage that should be seen for this circuit. 6 vdc. Nowhere else did anyone give this spec. Yes the transformer in the unit is 24 vac. That has nothing to do with this safety circuit. Thank you for giving me the answers I looked hours to get. I can finally assume my logic board is Ok.

Thanks a lot for the video! This is the only place in the universe that states the actual voltage supplied to the photocell circuit.

Thanks. Finally SOMEONE actually said what the DC voltage should be. The sensors must communicate back to the main unit via RF...

Excellent tip. Thank you very much. If knew this, I would not replace my sensors which did not solve my problem.

It saved my day, not able to fix my garage with the same problem, on my way back I searched for the solution , I found this video, took u turn and it worked perfectly

Thank you. Thank You and RU-vid. I am 78 and with your excellent instructions and information I fixed my garage door problem and learned how to avoid future problems. I am so proud of myself and thankful to my mother that taught me to "try before paying you might learn something for a lifetime". I subscribed and will share with family and friends. I like your handle "YOURSELF" 🙂

I just watch your videos and I had same problem and find out my left sensor was fal of from and put it back and exactly what you were saying and fixed the problem thank you so much save me a lot of money from calling technician

Thank you! My door was closing most of the way then reversing. I didn’t realize (or remember, in case I already knew it) about the light flashing code. Mine was flashing ten times, like you mentioned. There wasn’t any obvious obstruction between the two door sensors but the green one was flashing intermittently. Turns out that the garage door insulation that I installed years ago was puffing out just enough to be detected by the sensor. I pushed it in and problem solved. I’ve added some Tyvek tape to help prevent it from bulging back out again. Thanks again for steering me in the right direction!

Great guidance. Clear and concise. Worked for me - one sensor (receiver) was out of alignment. Thanks!!

Sensor out of alignment, as well. Thanks for going through the troubleshooting steps back to the power source. A lot more help than the manual or the online chatbot. Thanks for this!

Thank you so much. I've been trying so hard to find this information and you have it all on this video thank you so much. Now I know what my problem is

did not know where to start diagnosing a garage door since ive never done it, gonna give this a try thank you!

My door goes down to about a foot of closing and then reverses direction. Going to go through your troubleshooting tips. Thank you for the detailed explanation!

Thanks for the tips! Helped me diagnose my issue and opener now functions properly.

That was great. you saved my day. Thank you very much. I cleaned the sensors and it is closing properly now.

Your video was very helpful. I needed the voltage at the sensors and I could NOT find it on any other video. Much easier to know the voltage and not have to remove the sensors and run jumper wires to the back of the motor unit.

Great video. Helped me find the issue. Thanks 😊

Good explanation. Only video I've seen showing the voltage needed to operate sensors.

Very good video. Thank you. Clear and concise.

Excellent video & very good explanation. Thank you for sharing!

Your tutorial solved my problem. Many thanks.

Nice video sir!

Thank you! Your video helped me today with sensor issue!

Thank you for your video. I had a loose connection at the wire to the motor. I reconnected it and it fixed the issue

Ensuring the sensors are in line fixed it. Thank you for the explanation :)

Thank you sir!! You were right on point! Great info

Thank you very informative video I was able to fix mine as it was a broken wire to one of the sensors.

Great explanation!

Thank you thank you. Worked excellent video

DANG, this is a good video!!!! Thank You😊😊😊😊

Thank you so so so much it reallly helped I fixed my garage and I subscribe as well thank you so much man

Garage door: no, i wanna stay open!

Thanks. Seems like it is the cable for me. Was giving -1. But at the garage opener it was 14 or 16.

My sensors were aligned, door still not closing unless I pressed the button and held it down. Eventually I sprayed lube on the rails and wheels, and that fixed it 👍🏻

Thanks for the video. Cold weather seems to affect my door's ability to close with the remote. Have you any thoughts on this?

Thank you so much it was the sensor for me it was aiming high

Good comprehensive video. Probably too detailed for low info whiners like Sara Abernathy. Sara, I suggest sitting on the pointed end of the broom instead of complaining.

Does it need to be 6v on both the sender and receiver sensor .. I see 6.24v DC on sender and 0.91v on receiver .. is that a problem ?

Does the amber and green light should be visible when door is closed or open? Because ours didnt show but we can open from keypad and hold the keypad to close it.

Do you know why my garage opens an inch and it stays there I have a solid orange and solid green

Problem is, I have steady Green, so the sensors are lined up, so there's nothing for me to realign. However, I still have the same issue with having to hold the button down to close

I have 6 volts at the unit 6 volts at both sensors and with new sensors still the door comes down and then goes back up after it reaches about 1 ft from the top any more ideas

My garage door sensor orange and green light does grow steadily, but still can't close the door. Only closing all the way down while I keep holding the button. Please help. Thanks.

My handheld garage door opener won’t work after I change the battery

Mine wouldn't close because the lenses were dirty. I cleaned them with a wet rag and it started working again.

On the wires that go to the sensor each has 2 is one for power and other ? Or what

Use that broom to clean those corners

Don’t use pliers or the plastic will crack.

Can you
