this cold end header box acts as the central recovery point for acidic condensate produced during the combustion process

Excessive heat can cause the internal binder to fail or release captured moisture back into the system

Precise Modulation: Advanced modulating seat action maintains steady temperatures in high-volume cooking equipment like ranges and griddles

What is the difference between CFR and VFR settings on this board

The bulk polymer element and hydrophobic filter allow for reliable recovery from 100% saturation without permanent calibration shifts

Lennox 10M66 Limit Switch 323269-701 this cold end header boxThe Lennox 10M66 Limit Switch is a critical safety component engineered for precise thermal monitoring in high efficiency gas furnaces and air handlers. For technicians diagnosing a Lennox furnace limit switch opening prematurely or failing to reset, this SPST (Single Pole Single Throw) thermal sensor provides the exact calibration required for OEM compliance and system safety. Operating on a normally closed circuit, the 10M66 is designed to break the
