Lennox 44W57 Collector Box

Lennox 44W57 Collector Box

The Lennox 44W57 Collector Box (OEM #102109-04) is a critical condensating furnace replacement part engineered for high-efficiency gas furnaces, including popular Lennox G61MPV and EL195 series models. Often referred to by technicians as a cold end header box, this component is responsible for gathering and channeling corrosive condensate and combustion byproducts away from the heat exchanger and into the drain trap. Its internal pressure switch ports and drainage channels are precision-molded to ensure accurate vacuum signals for the inducer motor assembly, preventing common pressure switch lockout codes and poor drainage issues that lead to system shutdowns.

Constructed from high-grade, chemical-resistant composite, this genuine Lennox OEM furnace part is built to withstand the acidic nature of flue gas condensate. When troubleshooting Lennox furnace water leaks or repeated 0.65" W.C. pressure switch failure codes, inspecting this collector box for hairline cracks, clogged internal baffles, or blocked port channels is essential. Proper installation requires ensuring the furnace is correctly sloped toward the drain port to facilitate gravity-based drainage and prevent water log within the combustion residue collector chamber.

  • OEM Compatibility: Exact replacement for Lennox part number 44W57 and 102109-04, ensuring perfect fitment without field modification.
  • Critical Signal Integrity: Features molded vacuum ports that deliver precise pressure differentials to the system’s safety switches.
  • Corrosion Resistance: Engineered specifically for the harsh environment of high-efficiency condensing furnaces.
  • System Reliability: Eliminates bypass air leaks and drainage backups that cause nuisance trips in the control circuit.

Common Questions:

Why is water backing up into my pressure switch lines from the collector box?
This usually indicates a blockage at the bottom drain port or a failure of the internal baffles. If the furnace slope is incorrect or the condensate trap is clogged, water will rise until it enters the vacuum lines, requiring a thorough inspection or replacement of the box.

Can I repair a cracked collector box with sealant?
Field repairs with silicone or epoxy are not recommended for 102109-04 collector boxes. The vacuum-sealed environment must remain intact to ensure the inducer motor pulls the correct draft for safe operation. A crack usually warrants a full replacement of the 44W57 assembly.

Will this part fix a pressure switch stuck open error?
If the inducer is spinning and the venting is clear, a clogged port on the Lennox collector box is a frequent culprit. Clearing the port with a small drill bit or replacing the box often restores the pressure signal needed to close the switch.
