9724 – CONDENSER MOTOR (1/4 – 1/6 HP, 1625 RPM, 42Y, 5MFD)

If your AC fan isn’t spinning or spins slowly, the condenser fan motor is likely the problem. The Century 9724 covers three horsepower ratings (1/4, 1/5, 1/6 HP) at a higher 1625 RPM speed. Make sure your system calls for 1625 RPM — not 1075 — before installing.

Specs: 1/4, 1/5, 1/6 HP, 1625 RPM, 208-230V, 42Y frame, 5″ diameter, 5 MFD capacitor, TEAO, reversible

Replaces: 20223, 9724

Fits: Condensers requiring a 42Y frame motor at 1625 RPM. Less common than 1075 RPM units — verify RPM on your motor nameplate before purchasing.

• Common applications: 13-16 SEER residential condensers: Rheem / Ruud RA13/RA14/RA16, Goodman GSX13/14/16, Trane XR13/14/16, Carrier / Bryant 13-16 SEER, York / Coleman entry- and mid-tier condensers, Lennox 13-16 SEER
• Verify HP, RPM, frame size (42Y/48Y), shaft diameter, and rotation direction match before installing

Why didn't my condenser fan motor last?

9 times out of 10, a weak run cap drives the motor to fail. The cap loses MFD over time, the motor pulls higher amps, the bearings overheat. Replace the cap every 5-7 years and the motor lasts much longer.

How do I match HP, RPM, and frame size?

HP and RPM come off the data plate. Frame size (42Y/48Y) describes the mount dimensions — 42Y is the smaller frame, 48Y is larger. Shaft diameter is usually 1/2" but verify. Rotation (CW/CCW from shaft end) MUST match your existing setup. Bring the old motor in — we'll match every dimension at the counter.

What does '2-speed' mean on a condenser motor?

2-speed condenser motors have two RPM ranges (typically 850 and 1075). The control board chooses based on stage call. Useful for 2-stage condensers — won't help on a single-stage system.

How long does a condenser fan motor last in Dallas?

6-10 years typical. Open-frame motors exposed to rain, sprinkler overspray, and afternoon sun fail faster. Sun-side units typically die first.
