922140A Nordyne 208/230V 1Ph 3-Ton R22 Compressor

Must be shipped via truck line 

Description

The 922140A is an OEM hermetic reciprocating compressor engineered for Nordyne HVAC systems requiring a 3 ton (36,000 BTU/h) capacity. It operates on 208/230 VAC, single-phase power at 50/60 Hz, and uses R22 refrigerant. Designed for robust performance, it features built-in overload protection and anti-vibration mounting pads to minimize noise and extend service life.

Compatibility

• Nordyne split-system condensing units rated 3 ton (208/230 V, 1 Ph, R22).

• Rooftop and packaged heat pump models requiring a 3 ton R22 compressor.

• Direct replacement for Nordyne part number 922140 (original) and earlier revisions.

Always verify the outdoor unit’s data plate to confirm voltage, phase, capacity, and refrigerant type before ordering.

Installation & Service Tips

• Align the compressor’s mounting pads and motor shaft orientation to match the OEM bracket.

• Evacuate the system to at least 500 microns and verify a moisture-free vacuum before charging with R22.

• Install a new liquid-line filter drier downstream of the compressor to protect against moisture and debris.

• Torque suction and discharge line flare nuts to manufacturer specs (typically 14–18 ft·lb) to prevent leaks.

• Use a calibrated gauge set to monitor superheat and subcooling values during system charging.
