Remote keypad doesn’t activate opener

Craftsman model# 953964 1/2 HP installed in 2000. About ten years ago the motor went, and I had a spare opener that was never installed in the other garage, so I swapped out the opener unit.

last week the outside keypad stopped working. Still blinks when I enter the code so didn’t think it was the battery. Replaced battery anyway, still doesn’t work.

today I tried reprogramming the code, thinking maybe it was corrupted. The keypad responded to the main unit: I pressed the learn button, entered new code, hit enter, and lights on opener blinked, indicating a success. Still didn’t work.

I then took the keypad from the spare opener, which was never used, and programmed with a new code. Garage door opener responded by blinking, however, keypad would still not open the door.

I am now at a loss. Seems like the keypad is communicating to the opener, however, it just won’t respond to the code and open the door.

also the sensors that detect someone walking in or out of garage don’t work. They do work if something is blocking the door, and won’t close, they just don’t activate the lights when triggered. Not too worried about that, but don’t know if this is related. These stopped working over 10 years ago I believe.

 

Some inside wall controls have a switch on them that shuts down the remote portion of the opener.
It may be labeled lock.

 

There is a button on the wall console that prevents remote openers from opening garage door. This does not affect the remote keypad. also made sure this was not activated.

 

Probably a faulty circuit board, the keyless entry is stored in a different memory than the remotes, thus the remotes will activate the door but the keyless won't. Do you still have the old opener, swap out the old circuit board.

 

I do have the old opener, how easy is it to swap out circuit board?

 

Never mind - just googled circuit board replacement. Very simple, I’ll post back when completed.

 

When in doubt.....take pictures. A picture is worth a 1000 words.

 

Update:

I swapped out the circuit board with that of the old opener. Before I tried keypad, I tried closing garage door from console switch. I just heard a click, and nothing happened. Thinking back, this is what happened with the old opener, which is why I replaced it. I then programmed the keypad and tried but nothing happened. So I’m thinking the circuit board in the old opener is what is shot, maybe the motor is still good? I swapped back the circuit board, door opens/closes with console and remote, just not with the keyless entry. So at this point I’ll use it without the wireless keypad, until I get inconvenienced enough and buy a new opener.

 

Just throwing my two cents out there too. My opener was extremely finicky and I couldn’t narrow down any sort of pattern. One minute the remotes wouldn’t work, then the keypad outside wouldn’t work, yada yada. I found a replacement circuit board on eBay for like $30 and voila, that did the trick. Best $30 I ever spent lol. So glad I didn’t have to replace the whole thing. Now I’m thinking of switching that outlet to one with built-in surge protection, although I see that they sell those as “plug-ins” as well.

 

Garage door opener still works, just can’t use remote keypad, and I found an extra remote but it won’t program. Lights flash like it’s programmed but it doesn’t work.

I am now looking for a replacement circuit board (logic panel) however can’t seem to locate the correct one.

Craftsman part # is 41A5021-4H
chamberlain /Liftmaster lists replacement part as 41A5021-1.

i can find plenty of boards with 41A5021 buy the suffixes are all different letter/number combos. I do know if I purchase a Liftmaster/chamberlain I will have to swap out the logic board from the panel as it is not compatible. That’s fine, but I want to make sure I purchase the correct part. Does anyone know what the suffixes mean? And do I need the EXACT match?

 

This thread is 2 years old. Something tells me you really don’t need the keypad -lol!

Are you sure you can put a Chamberlain receiver board in a Craftsman opener? Maybe you can. Just seems strange though.

 

@Zoesdad I am a true procrastinator by trade, lol. My son used to use the keypad to get in the house after school. Short of installing a new opener I would like to at least program another remote or two, and see if I can finally get the keypad to work. Just need the control panel. And I read somewhere that chamberlain/ Liftmaster is actually the replacement for craftsman since its not made anymore. Just can’t use the actual backing that it’s attached to as it won’t fit. Just need the circuit board.

 

Join us... join us... in the 21st century.

The new Liftmasters connect to the internet. You can open & close them by phone. You can add access to permanent or temporary users' phones. You get a log of every open & close. They'll alert you if they've been open longer than you want. You never have to worry that you forgot to close the door.

The new openers are HomeLink compatible. You still get visor clip openers if you want but ours languish in a drawer. I'll pull their batteries soon.

 

Correct.... you just need the board.
The Craftsman model you originally posted is not complete.
I usually look up the actual model number for replacement parts.

Yes... Chamberlain manufactured your Craftsman opener.

I thought the different boards had different colored learn buttons.

You can also install a universal wired keypad. I keep one in stock at all times.
Simple two wire connection to opener. Runs on batteries.
Domino GD-1 keypad

 

I have a new keypad for the same unit, swapped it out but it didn’t work. Convinced it’s the board, so if I’m correct another keypad won’t work either.

like the idea of smart openers, just wasn’t ready to make the switch yet. Maybe soon.
