1173665 Condenser Fan Motor

What the Condenser Fan Motor Does

Your outdoor unit releases heat absorbed from inside your home. The condenser fan motor turns the fan blades to draw air across the outdoor coil.

When this motor fails to run, the system cannot expel heat properly. As a result, the outdoor unit overheats and shuts down to protect its internal parts.

Understanding the Specs for 1173665

A replacement motor must match the electrical and physical profile of your original unit. Part 1173665 carries specific ratings that must line up with your system setup.

• Frame: 48
• Phase: Single
• Rotation: Clockwise Lead End
• RPM: 825
• Shaft: 1/2"

How to Confirm a Replacement Matches

When finding a match, the motor HP must be the same. The RPM and volts must also be the same.

Check the rotation and shaft size. They must match, or you must pick a reversible motor that fits your bracket and blade hub.

Signs of Failure and Safe Replacement

A fan that hums but will not spin is often a bad capacitor, not a bad motor. A capacitor costs less, so check it first before replacing the motor. If the motor itself has seized bearings or failed windings, replacement is required.

A new motor often needs a new capacitor rated for it. Take a photo of every wire before removing the old part. Move wires one at a time to the same spots on the new part.

Read your old part

1. Turn off all power at the breaker and outdoor disconnect, and test for power.
2. Wipe the metal label plate on your existing outdoor motor to read the print clearly.
3. Check that the part number on the label reads 1173665.
4. Verify that the specs match Frame 48, Single phase, Clockwise Lead End rotation, 825 RPM, and a 1/2" shaft.
