The LiftMaster K29-ABC-2 Fuse is an OEM replacement overcurrent protection device rated at 250V, 2A, engineered for use in LiftMaster gate operators, garage door openers, and access control equipment. It safeguards control boards and accessory circuits by opening the circuit when current exceeds the specified rating, helping prevent damage and downtime. This ABC-2 designation aligns with a widely used cartridge fuse format found across many LiftMaster residential and commercial operator systems, making it a dependable replacement part for maintenance or repair.
Use the K29-ABC-2 when a blown fuse has interrupted operation and the operator’s documentation specifies a 2A, 250V cartridge fuse. Installation is straightforward: disconnect power to the operator, remove the failed fuse from the fuse clips or holder on the control board, and insert the new fuse with the same rating; no programming is required. For safety and proper performance, replace only with a fuse of identical rating and consult the model’s manual to confirm compatibility. This genuine LiftMaster component supports universal service needs across a range of operator types where an ABC-2 fuse is called out, covering both residential and commercial applications.
