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 the ICP WPG4424090RKB1 packaged gas/electric unit. The 1/2 HP blower motor (OEM 1188130) drives the indoor squirrel-cage blower that circulates conditioned air through the duct system, while the 1/5 HP, 810 RPM condenser fan motor (OEM 1186359) pulls air across the outdoor coil to reject heat during cooling. A failed motor shows up as no airflow, weak airflow, a humming motor that won't start, or a motor that runs hot and trips on its internal overload. Worn bearings produce a rumble or squeal that gets louder over time.

Compatibility

Direct fit for the ICP / Tempstar / Heil WPG4424090RKB1 packaged gas-electric unit. Verify the existing motor frame, shaft diameter, rotation, and HP against OEM 1188130 or 1186359 before ordering, and reuse a run capacitor only if it matches the new motor's MFD rating.

Installation Guide

Safety First — Disconnect power at the unit disconnect and verify zero voltage with a multimeter. Capacitors hold a charge — discharge before handling.
Access — Remove the service panel covering the blower or condenser section.
Document — Photograph all motor leads, the capacitor wiring, and the fan-blade position on the shaft.
Remove — Loosen the blade/blower set screw, pull the wheel or fan, disconnect leads, and unbolt the motor from its mount.
Install — Mount the new motor, set the blade at the documented depth, reconnect leads per your photo, and confirm correct rotation direction.
Test — Restore power, run the unit, and verify smooth startup, correct airflow, and no overheating.

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.
