The compressor circulates and pressurizes refrigerant, driving the entire refrigeration cycle that removes heat from your building. This scroll design delivers quiet, efficient operation with fewer moving parts than reciprocating units.\u003c\/p\u003e\u003cp\u003eWhen a compressor fails, you'll typically notice a system that runs but won't cool, tripped breakers or hard-start conditions, loud grinding or humming on startup, a compressor that overheats and locks out on internal protection, or a complete no-cool call. Electrical failures and worn internal scrolls are the most common culprits on high-hour units.\u003c\/p\u003e\u003cp\u003eChoosing the OEM Lennox \u003cstrong\u003e11B70\u003c\/strong\u003e matters because it is factory-matched to your unit's refrigerant charge, voltage, and BTUH capacity, ensuring the correct oil charge, displacement, and terminal configuration.
