If your programmed adjustments have become erratic or your keypad and remote have become unresponsive, you may need to replace your circuit board. As the brain of your garage door opener system, the circuit board must function properly to ensure a safely operating garage door system. Many times, a circuit board can become faulty due to power surges or lighting strikes. If your system began malfunctioning after a power outage, a faulty circuit board is most likely the culprit. Fortunately, North Shore Commercial Door carries an extensive selection of replacement circuit boards for every LiftMaster Chamberlain system and many Sears Craftsmen models.

It is important to always test your safety reversal system whenever you replace your circuit board. To ensure your new circuit board provides long-lasting performance, we recommend using a 990LM Garage Door Opener Surge Protector with your new board, as most faulty circuit boards are caused by power surges and lighting strikes.

ANSWER: Logic board. by Roy D a
ANSWER: I would bet your problem is with the circuit board... had the same situation about a year ago and tried everything just as you have only to finally replace the borad which solved the problem. Some circuits on the board are sensitive to lightening and other electrical issues... Newer boards have increased protection from such influences. It is not a hard job and takes little time. The part from Northshore was an exact fit... That would be my direction..... by the way it as been abut a year since I replaced the circuit board and all still works fine... Ray g by Raffael G a
