If your commercial garage door opener is not working properly, you may have a faulty circuit board. A faulty circuit board can cause problems with the keypads, remotes and sensors. A malfunctioning safety reverse system can be particularly dangerous. Replacing your circuit board is an economical way to restore your system back to flawless operation and prevent you from replacing the whole system. At North Shore Commercial Door, we carry circuit boards for every type of LiftMaster commercial opener.
The LiftMaster K1A6837 Logic 4 circuit board is compatible with all HP and voltage LiftMaster commercial operators. To ensure the LiftMaster K1A6837 circuit board is compatible with your commercial system, it is important to reference the Chamberlain LiftMaster Circuit Board Compatibility Chart. UL325 compliant, the K1A6837 circuit board requires CSPU photo eyes for momentary contact opener. Highly programmable for specific commercial applications, the LiftMaster K1A6837 circuit board’s features include:
• Maximum Run Timer
• Programmable Mid Stop
• Timer to Close
• Optional Maintenance Alert System
• Car Dealer Mode
The optional maintenance alert system (MAS) is a particularly useful feature for commercial use. To ensure your garage door opener system continues to function safely, it is important to schedule regular maintenance. The MAS feature keeps track of the amount of system cycles. By programming a preset amount of cycles, your system will alert you when maintenance is recommended.
For detailed instructions regarding installation and programming, please reference your system’s manual, which can be found in our extensive list of Product Manuals. With correct installation and programming, your LiftMaster K1A6837 circuit board can ensure your commercial garage door opener system is safe and functions optimally.
