The 41A5021-5 circuit board is the part you need to replace a faulty circuit board in your LiftMaster garage door opener. There’s no need to replace an entire garage door opener because of a malfunctioning logic board. North Shore Commercial Door has the replacement circuit boards and other parts you need to repair your garage door opener and keep it working properly.
The 41A5021-5 circuit board is identical to the 41A5021-5I circuit board. The letter designation at the end of the part number indicates the model year. North Shore Commercial Door recommends that you install a LiftMaster 990LM Garage Door Opener Surge Protector any time you replace a safety sensor or circuit board to protect your new parts from damage. We offer a discounted combo price when you buy the surge protector and the circuit board together.
