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 1/5 HP condenser fan motor (OEM #1186447, MOTOR CND 1/5 HP) drives the outdoor fan blade on the ICP/Tempstar/Heil WCH4374GKB100 condensing unit. It pulls ambient air across the condenser coil to reject heat during the cooling cycle (and the outdoor coil during heat-pump heating). When this motor weakens or seizes, the unit loses its ability to shed heat — causing high head pressure, compressor overheating, tripped breakers, and eventual compressor damage. Symptoms include a fan that won't spin, spins slowly, runs hot, or hums without turning. Installing the correct 1/5 HP OEM motor restores proper airflow and protects the compressor.

Compatibility

Direct-fit replacement for the ICP/Tempstar/Heil WCH4374GKB100 and other ICP-family condensing units using a 1/5 HP condenser fan motor. Verify horsepower (1/5 HP), shaft size, rotation, and mounting before installing; reuse your existing run capacitor only if it matches the new motor's rating.

Installation Guide

Safety First — Disconnect power at the breaker and disconnect; verify zero voltage with a multimeter and discharge the capacitor.
Access — Remove the top fan grille/panel to reach the motor and blade.
Document — Photograph all wiring and note the blade's position on the shaft.
Remove — Loosen the blade set screw, pull the blade, then unbolt the old motor from the bracket.
Install — Mount the new motor, transfer the blade at the same depth, and reconnect wiring per your photo.
Test — Restore power and confirm the fan spins up smoothly in the correct direction.

Signs You Need a Replacement

Outdoor fan won't start or spins slowly/intermittently.
Motor is hot to the touch, noisy, or has worn/grinding bearings.
Unit trips on high pressure or overheats during cooling.
Fan hums but the blade won't turn (often a failed motor or capacitor).

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.
