Late question but need an answer. These control boards have programming functions beyond what the manual covers. I had these instructions on old computer and lost them. Now I'm having trouble finding them again, buried on the internet somewhere. These boards can be set to operate without the safety "eye" sensors. I know this because I did it to mine years ago. A recent lightning strike took my control board out and I got a replacement. I want to program the new board the same way I programmed the old one but I can't find the special instructions. If I remember correctly, you press the red "learn" button for about 20 seconds, then you can get to the "service" modes. I can't remember how many button presses and LED light flashes, etc. I know there are modes this board can be set to beyond what the consumer manual shows. I'm going nuts trying to find those instructions again. Years ago I stumbled upon them where a gentleman had figured all this out and had it posted somewhere. I'm talking about the 14LG0607B (41D4674) boards.

I have a problem with my liftmaster 880MLW smart control panel wall switch with no function at all while all my 3sets remote liftmaster 893MAX and key switch all working, what's the solution for the wall switch.

Hello Mark, can I see a schematic?

[@mikemoore2934]

Mark , Thank you for the information. I changed out the logic board and that solved our remote problem.

[@nscommercialdoor]

Hello Mike! I'm so glad to hear that this video helped you with your garage door repair! I hope you had a great new years!

[@twoamigoslandscaping9913]

I have a Chamberlain Liftmaster ATS-2113s. Part# 41A5021-9G-315 Today I found the opener wouldn’t open. With remote, with push button or otherwise. I noticed the push button was pulsing barely green instead of the usual steady green light on open button. Checked breaker. Checked to make sure plug has power. It doesn’t do anything. Unplug it. Plug it back in, light does not come on, doesn’t make a sound. Like it’s totally dead. Will a new board help this or is there something else to check (internal fuses) or is it just junk? It’s like there is no power to it.

[@bpestcontrol1926]

Mark, thx for the info Vlog. I purchased from your webstore a new control board, however, this didn't repair my opener. I'm hearing a clicking noice when actuating the wall mounted garage door button but nothing moves. I'm now thinking the dual capacitors. I have A Lift master 2585 3/4 hp Estate Series. Do you carry these replacement parts? And should I replace the resistor that is in series with the capacitors? Appreciate your thoughts and any helpful suggestion to help. Thank you, Brooks

[@thebeatstunes8430]

I have a 3255 Iift master opener why does it cost after it shuts off ?

[@stobormachinery9487]

Great explanatory video. Thanks.

[@davidh4910]

My grave door opens up by it self every night around 8:50-9:10pm. I have reset the unit, erase all remotes and reprogram, unplug and plug , replace light bulbs, and unit still opens at the same time every night. Any suggestions?

[@nscommercialdoor]

What type of operator do you have?

[@akjeff64]

searched a logic board, got result of a key fob 🤔

[@judyhart5174]

Hello! There is a yellow light flashing and audible peep saying the battery back up is low in the large wall mounted box of our 3800 liftmaster.how do I fix this?

[@nscommercialdoor]

Hello Judy! We would love to help you get to the bottom of this issue! Could you please call us at 800-783-6112 or email [e-mail] with more information?

[@brucehayward9076]

Can I program the dip switches on a chamberlain 300mc to be compatible with any non dip switch lift master garage door opener

[@nscommercialdoor]

No, sorry. That remote will only work with 300MHz multi code systems. You could order the Liftmaster 375UT universal remote: www.northshorecommercialdoor.com/li37untr.html

[@stephenlightfoot7649]

Hi Mark, do you know of anywhere in the UK where I can buy a control board for a LM60AR? I have power up to the control board and then everything is dead. The only number I find is on the green board, 08170. Other numbers on the grey cover are, 132C2493-1, or, 014PC1027A. Hope you can decipher something from this. Thank you, Stephen

[@nscommercialdoor]

Hello, Unfortunately I am unable to bring anything up under those board numbers. Could you please take a photo of your control board and operator and send it to [e-mail]. That may be able to help us identify the board.

[@spencerberg7899]

my door will not close every time it balks ,lites flash ,then it returns to all open position, lites steady on two sensors and aligned too each other , minutes later it all works fine then agaign it balks when a remote is tried in car or remote on wall is tried , then again it will work fine, whats up?

[@nscommercialdoor]

Your circuit board is bad. Give us a call and we will set you up with the part you need. 800-783-6112

[@Synchrimedia]

our garage door opener sometimes stops working and i have to unplug it for a minute then plug it in again. then it works fine for a while. sometimes it goes out again a few days later though and it's kind of a pain. it's about 20 years old but still works fine otherwise. is there a part i should try replacing like the capacitor or logic board? should i plug it into a surge protector?

[@jeffjames7857]

synchrimedia what did you do to fix your garage door opener?

[@patrickbesong4264]

I didn't actually fix it. It might be from the very cold weather we'd been having. It hasn't done it since, but it's done it on occasion in warmer weather too. I figured out I can just hit the breaker it's on and when I reset it, it works again. No more climbing a ladder.

[@TL-ds8ux]

Recently all of my remotes have stopped working from a distance of more than 2-3 feet from the opener and only while inside the garage. Can you help me determine if I need to replace the control board? My opener is a Liftmaster with the purple learn button (315Mhz). Thank you.

[@slimpickinses]

mine too did you get a fix?

[@lancewrede2091]

Hello, there is no sound from my opener, the led by the yellowish orange reset button is dead, and the wall unit won't stop flashing fast little flashes. I am guessing that my board was fried by a power outage??? It is a chamberlain Access Master 41-A5021-1H-315

[@nscommercialdoor]

I apologize for the delay! That definitely sounds like a circuit board issue since the board is not drawing any power. Here is a link to the board that you need to order: www.northshorecommercialdoor.com/lich41gadoop2.html.

[@lancewrede2091]

Thank You

[@Remyredd007]

Hi Mark! Please help....My garage door is dead. The diagnostic LED light is flashing 5X which I believe suggests it's the motor. The service agent looked at it for 2 minutes and said it's the motor you need a new unit..$500! The unit is 9 years old. The wall/smart control panel has a message that says "power restored battery charging" but it's barely readable, very faint. When you push the "push bar" there is no clicking, just a beep. I called the 800 number and the rep said she thought it was the logic/control board. I don't know which part I should order and try first, the control board or a new motor. What do you suggest? Thank you!

[@nscommercialdoor]

What model is the opener?

[@Remyredd007]

Chamberlain Liftmaster elite series model 3850p-267

[@nscommercialdoor]

By any chance does your control panel look like this: www.northshorecommercialdoor.com/li88myqcopa.html

[@Remyredd007]

No, like www.northshorecommercialdoor.com/limo39smcopa.html

[@nscommercialdoor]

Ok, I would start with the board: www.northshorecommercialdoor.com/641lmib315rx.html If it does not solve your issue you can send it back.

[@briandimasi9611]

Hey Mark, my liftmaster goes up and down randomly, on its own. Could it be a bad board?

[@nscommercialdoor]

Please give us a call at 800-783-6112 and we'll work with you to figure out whats going on with your board!

[@mgenbarracuda2374]

Have you checked with your neighbors

[@mgenbarracuda2374]

Neighbours??

[@micahwatson9017]

Brian DiMasi - did you find out why your garage door was operating on its own? Mine is doing the same.

[@curtisp471]

These garage door opener boards are unreliable junk, and priced almost as high as an entirely new garage door opener...

[@nscommercialdoor]
