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 condenser fan motor (part #1186359) spins the outdoor fan blade on the ICP/Tempstar/Heil WPH4304000RKA1 heat pump, pulling air across the condenser coil to reject heat. Rated at 1/5 HP and 810 RPM, it is the workhorse that keeps head pressure in check during cooling and supports defrost in heat-pump heating. When this motor fails, the outdoor coil can't shed heat — the compressor runs hot, trips on high pressure or overload, and cooling capacity collapses. A motor that runs slow, hot, or noisy is on borrowed time and should be replaced before it takes the compressor with it.

Compatibility

Direct OEM fit for the ICP/Tempstar/Heil WPH4304000RKA1 heat pump. Verify HP, RPM, rotation, shaft diameter, and run-capacitor MFD against your existing motor before installing, as outdoor motors are matched to fan-blade pitch and unit airflow.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and breaker. Verify zero voltage with a multimeter.
Access — Remove the fan grille/top panel of the condensing unit.
Document — Photograph the motor wiring, capacitor leads, and the fan blade's position on the shaft.
Remove — Loosen the blade set screw, pull the blade, then unbolt the old motor from the bracket and disconnect leads.
Install — Mount the new motor, reinstall the blade at the same shaft depth, and reconnect wiring and the run capacitor per your photo.
Test — Restore power, call for cooling, and confirm the fan spins up to full speed in the correct 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.
