41C5498 Low Voltage Wire Harness Kit for AC Chain Drive Openers
The LiftMaster 41C5498 wire harness is used inside select AC chain-drive opener powerheads to restore the low-voltage wiring path. A low-voltage harness can be damaged by age, service work, pinched wires, rodents, corrosion, or a shorted accessory circuit. Symptoms may include intermittent wall-control operation, safety sensor wiring trouble, unreliable accessory connections, or visible harness damage. This is not the line-voltage harness and should not be substituted for high-voltage harness numbers. The correct harness must match the opener board connector, lead length, and routing so the low-voltage circuits remain properly separated and secured.
Compatible With
For use with select LiftMaster and Chamberlain AC chain drive garage door openers manufactured after 2001 that specify 041C5498 or 41C5498 in the replacement parts diagram. Supplier references also associate this part with select Craftsman/Chamberlain Group openers that call out 41C5498, with one noted caution that harness length may differ on some Craftsman applications such as 139.53985D. Verify original harness length and connector layout before ordering.
