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 is a genuine OEM X-13 ECM fan motor control (part number 1185844) for the ICP/Heil/Tempstar model WJA336000K000B1. The X-13 is a 1/2 HP electronically commutated (ECM) constant-torque blower motor that drives the indoor air handler or furnace blower. Its brushless DC design delivers quieter, more efficient operation than older PSC motors and holds steady airflow as duct static pressure changes. Common failure symptoms include the blower failing to start, intermittent operation, humming or buzzing, overheating, or the motor spinning up briefly then shutting down on internal protection. A failed ECM module typically leaves the blower dead while the control board still powers up normally.

Compatibility

Document — Photograph every wire and connector position before disconnecting anything.
Remove — Unplug the control and power harnesses, then unbolt the ECM module from the motor end-bell.
Install — Mount the new X-13 control, reseat the bolts, and reconnect each harness exactly per your photo.
Test — Restore power, call for fan, and confirm smooth ramp-up and steady airflow.

Frequently Asked Questions

Does this Fan Motor fit my ICP WJA336000K000B1 — 1/2 HP | Ships Today?

Yes. This is the factory-specified OEM fan motor for the ICP WJA336000K000B1 — 1/2 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 WJA336000K000B1 — 1/2 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.
