My AC fan is not spinning. What part do I need?

A fan that does not spin, spins slowly, or makes grinding or squealing noises needs a new motor. Grinding means the bearings have failed. Squealing means the bearings are dry. No spin with a humming sound means the capacitor may be the issue. Check the motor capacitor before replacing the entire motor.

Overview

This genuine OEM condenser fan motor (OEM part number 1186359) is the outdoor fan motor for the ICP / Tempstar / Heil WPH4424000RKA1 heat pump. Rated at 1/5 HP and 810 RPM, it spins the condenser fan blade that pulls air across the outdoor coil to reject heat during cooling and absorb heat during heat-pump operation. A failing condenser fan motor causes high head pressure, compressor overheating, and weak cooling — and if the fan stops entirely, the compressor can trip on its safety or fail prematurely. Replacing the motor with the correct OEM-spec unit restores proper airflow and protects the more expensive compressor.

Compatibility

Built as a direct factory replacement for the ICP / Tempstar / Heil WPH4424000RKA1 heat pump. It also fits related ICP-family condensing units that originally used a 1/5 HP, 810 RPM condenser fan motor. Confirm horsepower, RPM, rotation, shaft diameter, and voltage against your existing motor before installing, and reuse a matching run capacitor where required.

Installation Guide

Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage with a multimeter.
Access — Remove the top grille/fan assembly screws and lift the fan deck clear of the unit.
Document — Photograph the motor wiring, capacitor connections, and fan blade position on the shaft.
Remove — Loosen the blade set screw, pull the blade, then unbolt and disconnect the old motor.
Install — Mount the new motor, transfer the blade to the same shaft depth, and reconnect wiring per your photo.
Test — Restore power and verify the fan spins freely in the correct direction at full speed.

My AC fan isn’t spinning. What part do I need?

Fan not spinning, spinning slowly, or making grinding/squealing noises = motor failure. Grinding = bearings failed. Squealing = bearings dry. No spin + hum = check the motor capacitor first before replacing the entire motor.

Is this fan motor compatible with Bryant or Payne too?

Many ICP parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.

Should I use OEM or aftermarket for my ICP fan motor?

OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
