ICP Condenser Fan Motor 1/5 HP for WPG4364090LKA1 — 825 RPM | Ships Today

Overview

This is a genuine OEM 1/5 HP condenser fan motor (OEM Part No. 1186359, "MOTOR CND 1/5 HP") for the ICP / Tempstar / Heil WPG4364090LKA1 packaged unit. The condenser fan motor spins the outdoor fan blade that pulls air across the condenser coil, rejecting the heat the system absorbs from inside the home. Without adequate condenser airflow, head pressure climbs, the compressor overheats, and cooling capacity collapses. This motor is rated at 1/5 horsepower and is the direct factory replacement for the outdoor fan position. Condenser fan motors fail from worn bearings, overheating, and electrical breakdown of the windings — often accelerated by years of outdoor exposure to heat, dust, and moisture. A failed condenser fan motor is one of the most common warm-weather service calls: the compressor may run while the fan sits still, quickly driving the unit into a high-pressure trip. Typical symptoms include a fan that hums but won't turn, a blade that spins freely by hand but not under power, a motor that is hot to the touch and cuts out on thermal overload, and grinding or screeching bearing noise.

Specifications

Compatibility

This 1/5 HP condenser fan motor is the factory-specified outdoor fan motor for the ICP / Tempstar / Heil WPG4364090LKA1 packaged unit and is shared across many ICP-family condensing and packaged units of similar capacity. Confirm horsepower, rotation, shaft diameter, and voltage match your existing motor before installing, and reuse the correct run capacitor for the new motor.

Installation Guide

1. Safety First — Disconnect power at the unit and breaker, then verify zero voltage at the motor leads with a multimeter.
2. Access — Remove the top fan grille/panel to reach the motor and blade.
3. Document — Photograph the wiring, blade position on the shaft, and motor orientation before disassembly.
4. Remove — Loosen the blade set screw and pull the blade, disconnect the motor leads, and unbolt the motor from its mount.
5. Install — Mount the new motor in the same orientation, transfer the blade at the same shaft depth, and reconnect the leads and capacitor per your photo.
6. Test — Restore power, start a cooling call, and confirm the fan spins up to full speed in the correct direction with no wobble or noise.

Signs You Need a Replacement

• Outdoor fan hums but the blade won't spin (with a good capacitor).
• Motor runs hot and shuts off on thermal overload, then restarts when cool.
• Grinding, screeching, or rumbling bearing noise from the fan.
• Compressor runs but the unit trips on high pressure because the fan is dead.
