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 number 1186359) is a 1/5 HP, 810 RPM motor built for the ICP/Tempstar/Heil WPH4604000RKB1 heat pump. The condenser fan motor pulls air across the outdoor coil to reject heat during cooling and absorb it during heating. When bearings wear or windings short, the motor overheats, runs slow, seizes, or cuts out on thermal overload — causing high head pressure, weak cooling, breaker trips, and eventual compressor damage. A correctly rated 1/5 HP / 810 RPM replacement keeps airflow and head pressure where the system was designed to run.

Frequently Asked Questions

Does this Fan Motor fit my ICP WPH4604000RKB1 — 810 RPM | Ships Today?

Yes. This is the factory-specified OEM fan motor for the ICP WPH4604000RKB1 — 810 RPM | 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 WPH4604000RKB1 — 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.
