Specs: 1/4-1/8 HP, 825 RPM, 208-230V, 48-frame, 5 MFD or 7.5 MFD capacitor, reversible rotation

Replaces: 1874, K55HXCLP-1470, K55HXCLP1470, WG840459

Fits: Universal 48-frame condenser units requiring 1/4 or 1/8 HP at 825 RPM. Compatible with Goodman, Carrier, Rheem, Trane, and other brands.

• 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.
