Tempstar Condenser Fan Motor 1/5 HP for TXH542GKA200 — OEM 1177593 | Ships Today

Overview

This is the OEM 1/5 HP condenser fan motor (part number 1177593) for the Tempstar TXH542GKA200 heat pump/condensing unit. The condenser fan motor drives the outdoor fan blade that pulls air across the outdoor coil to reject heat in cooling and absorb it in heating. When this motor weakens or fails, the unit loses its ability to exchange heat, causing high head pressure, short cycling on the high-pressure switch, and warm air at the supply registers. A 1/5 HP motor at this rating is a direct-drive, sleeve-bearing design matched to the original blade and shroud for correct airflow and amp draw.

Compatibility

Engineered as the factory replacement for the Tempstar TXH542GKA200 and shared-platform ICP/Heil units using the same outdoor section. Always confirm the part number on the existing motor before ordering.

Installation Guide

1. Safety First — Disconnect power at the outdoor disconnect and verify zero voltage at the motor leads with a multimeter.
2. Access — Remove the top grille/fan assembly screws.
3. Document — Photograph all wire connections and the blade position on the shaft before disconnecting.
4. Remove — Loosen the blade set screw, pull the blade, unbolt the motor from the mount, and disconnect the leads and run capacitor wires.
5. Install — Mount the new motor, transfer the blade at the same depth, and reconnect wiring per your photo, including the correct capacitor terminal.
6. Test — Restore power, verify smooth rotation, correct direction, and amp draw within nameplate.
