LiftMaster 20-3200C-4TP TEFC Three-Phase Motor — Verify 2 HP Manufacturer Specification

The LiftMaster 20-3200C-4TP is listed in manufacturer catalog information as a 2 HP, 230/460 V, three-phase, CF/TEFC motor. The supplied product title instead says 1-1/2 HP, so that rating conflict must be resolved against the current delivered motor nameplate and exact operator recommendation before purchase. Do not select the motor solely from the shortened source title. Select the replacement by the complete part number and the installed equipment configuration. A similar photograph or a shared LiftMaster brand name does not establish interchangeability. Confirm the applicable service drawing before ordering so the repair addresses the correct component and its related mounting, connection and operating requirements.

Compatibility — Models, Versions and Exclusions

Identify the Assembly and Plan the Repair

Have qualified service personnel assess the motor, supply and driven equipment before choosing the repair. A failed motor can accompany excessive load, electrical faults or a damaged transmission. Obtain the actual motor nameplate and full operator label and have the supplier confirm the current assembly and rating in writing when resolving the catalog-title difference.

TEFC identifies a motor enclosure construction, not a new environmental rating for the entire operator. No unlisted speed, shaft dimension or universal upgrade is inferred here. Follow the exact wiring and protection requirements and restore the approved drive arrangement. A higher horsepower description does not authorize increasing the door or gate capacity. Complete the prescribed electrical and operating tests after installation.

An electrical symptom does not identify the failed component by itself. Have qualified service personnel inspect the supply, wiring, connections and equipment condition before replacing parts. Record existing labels and terminal references with power safely isolated. A replacement should restore the documented circuit arrangement; it should not be used to change operating voltage, defeat a protective function or compensate for a mechanical load that the equipment cannot safely move.

Specifications and Product Identification

Before Ordering

• Record the complete equipment model, serial information and installed service reference.
• Confirm the current 20-3200C-4TP service recommendation.
• Resolve manufacturer 2 HP versus source 1-1/2 HP wording.
• Verify actual voltage, phase and approved connections.
• Confirm the current supplied inventory and exact installation and final testing instructions.

Package Contents and Separate Requirements

This offer identifies the motor service reference. Confirm current rating and supplied mounting, shaft-retention and connection pieces after resolving the horsepower conflict. A gearbox, brake, electrical box, control board, full drive assembly and operator are not established as included with the motor.

Safety Warnings — Read Before Installation or Service

• WARNING: Electrical service can expose hazardous voltage and moving equipment. Use qualified service personnel and electrical personnel where required.
• Disconnect every applicable mains, battery and auxiliary supply before work. Follow the equipment instructions for stored energy and safe isolation.
• Resolve the source horsepower conflict against the current nameplate before purchase. Use the approved motor, protection and wiring; do not increase operator capacity or bypass required safety devices.
• Restore covers and wiring protection, then complete the model-specific functional and safety checks before returning the installation to normal use.

Related Products and Important Differences

• CPS-U monitored photo eyes — separate protection devices for approved commercial-door controls; match the operator and environment.

Frequently Asked Questions

Is the source 1-1/2 HP title verified?

The manufacturer catalog lists 2 HP. Resolve the discrepancy against the current motor nameplate before purchase.

Does TEFC rate the whole operator enclosure?

No. It describes the motor construction; the complete installation has separate requirements.

Can this increase operator capacity?

No capacity conversion is established. Use only the approved complete operator configuration.

Are speed and shaft dimensions stated?

No unverified values are claimed. Confirm the current complete motor specification and application.
