Overview
This is the genuine OEM 1/4 HP condenser fan motor (part #1177473) for the Tempstar TXA649GKA100 outdoor unit. The condenser fan motor drives the fan that pulls air across the outdoor coil, rejecting the heat your system removes from the home. When this motor fails, the compressor runs without adequate heat rejection, head pressure climbs, and the unit overheats and trips on its high-pressure or overload protection. Common failure symptoms include a fan that hums but will not start, a fan that spins slowly, bearing noise or grinding, intermittent operation as the motor overheats, or a condenser that gets dangerously hot to the touch. Replacing the motor with the correct 1/4 HP OEM unit restores proper airflow and protects the compressor.

Compatibility
Engineered as a direct OEM replacement for the Tempstar TXA649GKA100 condensing unit. This is the factory-specified motor for that model and is also used across related ICP / Heil / Comfortmaker condenser platforms that share the TXA chassis. Always confirm against your unit's nameplate and existing motor data plate before installing.
Installation Guide
- Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage at the contactor with a multimeter.
- Access — Remove the top fan grille/panel screws and lift the fan assembly clear of the cabinet.
- Document — Photograph all motor wiring and the run capacitor connections before disconnecting anything.
- Remove — Loosen the fan blade set screw, pull the blade, then unbolt the old motor from the bracket and disconnect its leads.
- Install — Mount the new 1/4 HP motor, transfer the fan blade to the same depth, and reconnect leads to the capacitor and contactor per your photo.
- Test — Restore power, confirm the fan starts immediately and spins in the correct direction (drawing air up), and verify normal head pressure.
