Overview
This is a genuine OEM 1/5 HP condenser fan motor (part number 1177593) for the Tempstar T4A436GKD100 air conditioning condenser. The condenser fan motor spins the outdoor fan blade that pulls air across the condenser coil, rejecting heat from the refrigerant so the system can cool your home. When this motor fails, the compressor continues to run but cannot shed heat, leading to high head pressure, short cycling on the high-pressure or thermal limit, warm air at the registers, and eventual compressor damage. Common failure symptoms include a humming outdoor unit with a stationary or slow-turning fan, a fan that needs a push to start, a burnt-electrical smell, or a unit that trips its breaker. Replacing the motor promptly protects the far more expensive compressor.

Installation Guide
- Safety First — Disconnect power at the outdoor disconnect and verify zero voltage with a multimeter at the motor leads.
- Access — Remove the top grille/fan shroud screws and lift the fan assembly clear of the cabinet.
- Document — Photograph all wire connections and the fan blade position/spacing before disconnecting anything.
- Remove — Loosen the fan blade set screw, pull the blade, then unbolt the old motor from the shroud and disconnect the leads.
- Install — Mount the new motor with the shaft facing the same direction, reinstall the blade at the recorded height, and reconnect leads per your photo and the new motor's wiring diagram.
- Test — Restore power, confirm the fan spins freely in the correct direction, and verify the unit cools with normal operating pressures.
Signs You Need a Replacement
- Outdoor unit hums but the fan does not spin, or needs a manual push to start.
- Warm air at the supply registers while the condenser is running.
- Hot, noisy, or grinding motor bearings, or a burnt-electrical odor.
- Repeated high-pressure trips or breaker trips during a cooling call.
