TE Connectivity KHAU-17A12-120 Relay 321702-401 What is the primary function

What is the primary function of the Copeland 918-0028-00

you know that a failing Lennox 67K32 furnace pressure switch is often the culprit when a unit refuses to ignite or locks out after the inducer motor engages

This is a PSC motor that requires a specific run capacitor (typically 2-3 MFD)

Precise Metering: Utilizes a C-charge to provide stable superheat across a broad temperature range (50°F to -10°F)

ensuring the HVAC system maintains correct static pressure and optimal SEER2 ratings
