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 OEM motor set keeps air moving through your ICP / Tempstar / Heil WPH4424000RKB1 heat pump. It includes the 1/2 HP blower motor (Part No. 1188130) that circulates conditioned air through the air handler, and the 1/5 HP, 810 RPM condenser fan motor (Part No. 1186359) that pulls air across the outdoor coil to reject heat. A failing motor causes weak airflow, overheating, tripped limits, and eventually a no-cool/no-heat condition. Because both motors carry the original ICP specifications, the system delivers rated CFM and amp draw without rebalancing.

Compatibility

Engineered for the ICP/Tempstar/Heil WPH4424000RKB1 packaged heat pump. The blower motor serves the indoor air-handling section while the condenser motor mounts to the outdoor fan bracket. Verify shaft diameter, rotation, and mounting before installing if your unit was previously serviced with non-OEM parts.

Installation Guide

Safety First — Disconnect power and verify zero voltage with a multimeter.
Access — Remove the service panel covering the failed motor (indoor blower deck or outdoor fan shroud).
Document — Photograph all motor leads, capacitor wiring, and the fan blade or wheel set-screw position.
Remove — Pull the blade/wheel, unbolt the motor mounts, and disconnect the leads.
Install — Mount the new motor, reinstall the blade/wheel at the same depth, and reconnect leads and the run capacitor per your photo.
Test — Restore power and confirm correct rotation, smooth spin-up, and normal amp draw.

Signs You Need a Replacement

Frequently Asked Questions

Does this Fan Motor fit my ICP WPH4424000RKB1 — 1/2 HP / 1/5 HP | Ships Today?

Yes. This is the factory-specified OEM fan motor for the ICP WPH4424000RKB1 — 1/2 HP / 1/5 HP | Ships Today. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.

How do I replace the fan motor on my ICP WPH4424000RKB1 — 1/2 HP / 1/5 HP | Ships Today?

Difficulty: Medium-Hard (1–2 hrs)
Step 1: Turn off breaker. Step 2: Note motor specs: HP, RPM, voltage, rotation direction. Step 3: Remove old motor from mounting. Step 4: Transfer fan blade to new motor. Step 5: Mount new motor, reconnect wiring. Step 6: Restore power, verify rotation direction.

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.
