OEM Lennox Reciprocating Compressor 61,500 BTU 575V — 11A76

The Lennox 11A76 is a genuine OEM reciprocating compressor (CRNQ-050E-TFE-970) rated at 61,500 BTUH for 575V, 3-phase R-22 systems. This piston-driven compressor pressurizes refrigerant to move heat through your Lennox air conditioning or heat pump system and is engineered for the higher-capacity demands of larger 5-ton applications. As a direct factory replacement, it restores full cooling capacity to legacy R-22 equipment.

Common failure symptoms: the compressor draws locked-rotor amperage and trips overloads, refuses to start or hums loudly, produces little or no cooling, cycles on and off rapidly, or makes knocking and valve-clatter noises. Overheating, a burnt-out winding, or worn internal valves and pistons are common reasons a reciprocating compressor of this age needs replacement.

Why OEM matters: the 11A76 matches Lennox's exact displacement, R-22 refrigerant compatibility, and 575V electrical specifications, ensuring correct system pressures and rated performance. For R-22 systems, sourcing the correct genuine compressor is critical since substitutes may not match oil type or capacity. Choosing the authentic Lennox part keeps your system running to spec and safeguards your warranty coverage.
