The LiftMaster 35-204 FUSE is an OEM overcurrent protection component rated at 4A, 125V AC, designed for select LiftMaster garage door openers, gate operators, and commercial door operator control boards. It safeguards control and power circuits by opening when current exceeds the specified rating, helping prevent damage to logic boards and transformers. This direct replacement part is intended for units that specifically call out part number 35-204 in their service manuals or parts lists, making it a reliable choice for maintenance and repair in both residential and commercial applications.
Electrical rating is 4A at 125VAC. Always replace like-for-like using the exact rating and part number specified by the operator’s documentation. Installation typically involves disconnecting power, locating the fuse on the control or power board, removing the blown fuse from the holder, and inserting the new fuse fully before restoring power; no programming steps are required. If the fuse opens again after replacement, diagnose the underlying cause (shorted wiring, failed components) before further operation. Do not bypass the fuse or substitute different ratings. Confirm compatibility by checking your LiftMaster model’s manual or parts diagram for 35-204 to ensure proper fit and function.
