The LiftMaster 41A6335 high voltage wire harness kit is used to restore the internal line-voltage wiring path on select screw drive garage door opener powerhead assemblies. In practical service, this part may be needed when the original harness has a damaged plug, heat-stressed insulation, broken leads, or a missing connector after a motor, logic board, capacitor, or powerhead repair. It is a fitment-sensitive electrical part: the lead length, connector style, routing, and board connection must match the opener parts diagram. Even if another harness looks close, a different high-voltage harness can route incorrectly or connect to the wrong component. This kit is best selected by matching the opener model and original part number, not by wire color alone.
Commonly associated with select LiftMaster, Chamberlain, and Craftsman screw drive garage door openers that identify 041A6335, 41A6335, or related 41A6635 in the parts diagram. Manufacturer references describe 041A6335 as compatible with various screw drive garage door openers. Use careful verification on older screw drive units because several high-voltage harnesses exist for different model years and internal layouts.

Disconnect power before any opener service. This harness is part of the high-voltage side of the opener and should be installed only by someone qualified to service garage door opener electrical assemblies.
If the opener has burning odor, tripped breakers, melted wiring, or repeated electrical failure, replace parts only after the root cause is found. A harness alone will not correct a failing motor, shorted board, or unsafe wiring condition.
41A6335 is a high-voltage wire harness kit for select screw drive garage door openers. It is not the wall-control or safety-sensor wiring harness.
It is commonly associated with select LiftMaster, Chamberlain, and Craftsman screw drive openers that list 041A6335, 41A6335, or 41A6635 in the parts diagram.
No. Harness length, routing, and connector layout can vary by opener generation, so the original part number and model parts diagram should be checked.
LiftMaster lists 41A6635 as an also-known-as reference for 041A6335, but the opener parts diagram should still be used to confirm fitment.
It may help if the original high-voltage harness is damaged, but no-power problems can also involve the outlet, power cord, transformer, logic board, or motor circuit.
