Unresponsive remotes and keypads can be an inconvenience, but faulty safety sensors can be potentially dangerous. If your garage door opener system isn’t working properly, it is important to quickly fix your system. However, a malfunctioning system doesn’t necessarily mean it needs to be replaced. Replacing its circuit board may be a simple, economical and Do-It-Yourself solution. The circuit board is most likely the cause for malfunction, if there had been a recent power outage or lighting strike, as power surges are the main cause for circuit board damage. In most cases, installing your circuit board can be accomplished without the assistance of a professional.
If you own a faulty LiftMaster 3595S Heavy Duty Chain system with a single motor capacitor (390 MHz), a replacement LiftMaster 41AC075-2S-390 circuit board may resolve your system’s problems. Easy to install and program, the LiftMaster 41AC075-2S-390 circuit board is equipped with a red learn button to easily program the drive limits, travel limits and remotes. To program multiple remote controls, follow these simple steps.
• Press and release the red Learn button. An indicator light on the board will glow for 30 seconds.
• Press and hold the remote control’s button you wish to program while the indicator light is on.
• When the indicator light on the board begins to blink, your remote control is now programmed. Programming your travel limits and drive limits is also a simple process. It’s important to remember that when adjusting one setting, you may need to adjust others as well for the system to function correctly. For detailed instructions on installation and programming, please reference the LiftMaster 41AC075-2S-390 Product Manual. To safeguard your new replacement circuit board against future power surges, we recommend using a 990LM Garage Door Opener Surge Protector for lasting operation.
