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) drives the outdoor fan on the ICP/Tempstar/Heil WPG4604090RKB1 packaged unit. Rated at 1/5 HP and 810 RPM, it pulls air across the condenser coil to reject heat during the cooling cycle. A failing condenser motor causes high head pressure, weak cooling, compressor overheating, and eventual compressor lockout. Common failure signs include a motor that hums but won't spin, a hot or seized bearing, or a fan that runs intermittently. Replacing a worn motor promptly protects the much more expensive compressor.

How do I replace the fan motor on my ICP WPG4604090RKB1 — 1/5 HP 810 RPM | 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.
