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 1/2 HP ECM blower motor (part number 1185157) drives the indoor blower wheel on your ICP WAPT364A2, moving conditioned air through the ductwork on both heating and cooling cycles. Unlike a fixed-speed PSC motor, this electronically commutated motor (ECM) ramps smoothly through multiple speeds for quieter operation, better humidity control, and lower electricity use. When a blower motor fails, you lose airflow entirely: the system calls for heat or cool but no air comes from the registers, or the motor hums and struggles without spinning up. Overheating, hot-shutoff cycling, grinding bearings, and intermittent no-start conditions are all signs the motor is wearing out.

Installation Guide

Safety First — Disconnect power at the breaker and verify zero voltage with a multimeter.
Access — Remove the blower compartment service panel.
Document — Photograph the motor power and control harness connections and the blower wheel position before disconnecting.
Remove — Unplug the harness, loosen the set screw on the blower wheel, pull the blower assembly, and unbolt the failed motor from the housing.
Install — Mount the new ECM motor, reinstall the blower wheel at the same depth, torque the set screw, and reconnect the harness per your photo.
Test — Restore power and verify smooth ramp-up and correct airflow on both heat and cool calls.

Signs You Need a Replacement

Frequently Asked Questions

Does this Fan Motor fit my ICP WAPT364A2 — 1/2 HP ECM Variable Speed | Ships Today?

Yes. This is the factory-specified OEM fan motor for the ICP WAPT364A2 — 1/2 HP ECM Variable Speed | 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 WAPT364A2 — 1/2 HP ECM Variable Speed | 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.
