Lennox 64J12 Collector Box Assembly
The Lennox 64J12 Collector Box Assembly (Model LB-66579C) is the critical OEM replacement cold end collector box for legacy high-efficiency furnaces. Designed as a direct swap for Lennox G26, 90UGF, and G32 series units, this genuine HVAC replacement part is identical to the 64J1201 catalog number. It functions by sealing the secondary heat exchanger's exit point to manage the transition of corrosive combustion condensate and exhaust gases toward the inducer blower and venting system.
For service technicians, the 64J12 is the primary solution for furnace leaking water from collector box issues, which often stem from hairline cracks in the plastic housing or degraded internal gaskets. Restoring the airtight seal at the "cold end" is essential to prevent pressure switch trip codes and ensure proper condensate drainage. Using this precise Lennox furnace part maintains the factory-engineered static pressure required for safe combustion across all residential heating cycles.
Key Benefits for Contractors:- Universal Compatibility: Engineered for a precise fit in Lennox G26, 90UGF, and G32 engineering revisions.
- Durable Construction: High-grade composite materials resist the acidic nature of furnace condensate for long-term reliability.
- Direct Replacement: Matches the footprint of the original LB-66579C to simplify reconnecting pressure switch tubing and drain lines.
- System Safety: Prevents bypass of combustion byproducts into the cabinet, ensuring air quality and operational safety.
Is the 64J12 the same as the 64J1201?
Yes, 64J12 is the catalog number and 64J1201 is the specific part number; they are identical and interchangeable components.
Will this fix a furnace leaking from the bottom of the inducer?
If the leak is originating from the junction where the inducer meets the housing, a cracked Lennox collector box assembly is the typical culprit. Replace the box to resolve the leak and prevent future component failure.
Does this include the gasket?
This collector box assembly is typically supplied with the necessary mounting interface; however, it is standard practice to inspect the inducer gasket and replace it if it shows signs of compression set.
