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 ECM X-13 motor control (part number 1185842) is the 1/2 HP variable-speed fan motor engineered for the ICP/Tempstar/Heil WPA4244000RKA1 heat pump unit. The X-13 is a constant-torque electronically commutated motor (ECM) that delivers higher efficiency and quieter operation than a standard PSC motor. When this motor fails, the outdoor fan stops turning, the unit overheats on a high-pressure trip, and the system loses its ability to cool or pump heat. Replacing it with the correct OEM-rated 1/2 HP control restores proper airflow and protects the compressor.

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.
