Is your logic board the problem?

The logic board is the opener’s brain — it reads the limits, the safety inputs and the radio, then drives the motor. It is also frequently blamed for faults it did not cause, so work through this before ordering.

Symptom	Likely cause
Opener dead, no lights, no response from anything	Power first — breaker, outlet, then the board
Runs one direction only	Often the board, but check the limits and the safety sensors first
Will not close, reverses on the way down	Safety sensors, not the board. Check the LEDs on both eyes.
Wall button works, remote does not	The receiver half of the board, or a remote that needs reprogramming
Resets or reboots mid-cycle	The board, or a supply voltage problem feeding it
Motor hums but the door does not move	Capacitor or drivetrain, not the board
Burnt smell, visible scorching or a bulged capacitor on the board	The board, definitively

Order by the number printed on the board, not by your opener model. Boards changed several times within the same model run, so two openers with identical model numbers on the cover can take different boards. Take the cover off and read the part number on the board itself.

After fitting

A replacement logic board arrives unprogrammed. You will need to reprogram every remote and keypad, and reset the travel limits and force settings before the door will work correctly. Budget twenty minutes for that, not two.

Common questions

Will this fit my opener? Check the number printed on your existing board against the part number above. If it matches, or matches one of the alternate numbers listed, it fits. If you cannot read it, send us a photo.

Do I have to reprogram my remotes? Yes. A new board has an empty radio memory. Reprogram each remote and keypad after fitting.

Is this genuine? Yes, genuine OEM. Aftermarket logic boards exist but fitment and firmware behaviour vary, and a board is not the place to economise.

Do I need to reset the limits? Yes, travel limits and force settings after any board replacement.

My opener is a Chamberlain / Craftsman. LiftMaster, Chamberlain and Sears Craftsman share the same platform, so the same boards fit across all three where the part number matches.

Just what I needed

Posted by Buddy Childs on Aug 26th 2016

Due to an electrical surge during a resent lightening storm all 3 of my Liftmaster garage door openers stopped working. I some result I discovered that the most likely cause was because the control boards were fried. I contacted a local garage door repair service for a repair quote. They wanted $450 dollars to repair all three opener. After an internet search I found the OEM parts I needed at gatehouse with instructions on how to install. I was able to save $265 by doing the repair myself. gateway was able to get the parts from California to Georgia in 3 days using normal shipping. 45 minutes after receiving the parts all 3 garage door openers were working again. The parts were cheaper ($12 each) than from Amazon. Gatehouse will be my first choice for electronic parts. I have provided Gatehouse contact information with the Maintenance Manager at the Company where I work.

liftmaster door opener logic board

Posted by Stephen Groschen on Jul 20th 2013

The board fits like a glove. I have now replaced four of these due to (?) low voltage meltdown of the CB which takes out just enough of the CB to render the whole thing worthless. This in the face of "good sized" surge protectors. Hmm.
Gatehouse has the price point and distribution. I would recommend them without question.
