LiftMaster H5011 Replacement Parts — H Series Industrial-Duty Hoist Operator

Genuine LiftMaster replacement parts for the H series industrial-duty hoist operator, 2005 to current production. The H5011 is the most common version — 1/2 HP, 115V, single phase. Use the exploded diagram to identify your part by its key number, then match it to the tables below.

Your model number is on the operator’s data label. The first two digits are horsepower and the last two are voltage and phase, so H5011 is 1/2 HP at 115V single phase and H5023 is 1/2 HP at 208/230V three phase. The H is handed — frame plate kits and frame rails come in left and right versions that do not interchange.

Motor Replacement Kits

The motor’s part number is printed on the motor’s own data label. If you can reach it, read the number straight off the label and match it below — that is the most reliable way to order the right motor. If the label is unreadable, find your model number in the first column. TEFC motors are the NEMA 4/12 enclosure versions.

Electrical box parts. The H shares its control boxes with the J and HJ, and those boxes use different parts from the T and GT versions — check the part numbers below rather than assuming. The H was also offered in a NEMA 4/4X enclosure and, on early units, the contactor-style box.
