The genuine OEM Lennox 49W16 is a Bristol H82J183ABC reciprocating compressor rated at 18,100 BTUh (roughly 1.5 tons) for 208/230V single-phase R-410A systems. This piston-driven compressor pumps and pressurizes refrigerant to power the cooling cycle in your Lennox condensing unit, delivering dependable capacity in a rugged, field-proven design.
Common failure symptoms: watch for a compressor that buzzes or hums without starting, repeated breaker trips, insufficient or no cooling, oil leaks around the shell, excessive vibration or knocking, and internal overload cycling. Shorted, open, or grounded windings and mechanical seizure are the usual reasons a reciprocating compressor reaches end of life.
Why OEM matters: installing the factory-specified 49W16 ensures the exact BTU capacity, R-410A rating, and electrical spec your Lennox system was engineered around. OEM sourcing safeguards system efficiency, prevents refrigerant and voltage mismatches, and helps maintain warranty coverage — advantages generic aftermarket compressors can't reliably provide.
