A furnace pressure switch is a safety device that confirms the induced-draft (inducer) motor is moving combustion gases properly before the control board allows the gas valve to open and the igniter to fire. It senses the negative pressure created by the inducer through its connected tubing; if adequate draft isn't present — because of a failed inducer, a blocked flue or condensate drain, or a cracked hose — the switch stays open and locks out ignition to prevent unsafe operation. Over time the switch contacts wear or stick, and the tubing cracks or clogs, causing nuisance lockouts even when draft is fine. This assembly includes the tubing for a complete, reliable repair.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpec\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eOEM Part Number\u003c\/td\u003e\n\u003ctd\u003e1178417\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eFurnace Pressure Switch\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIncludes\u003c\/td\u003e\n\u003ctd\u003ePressure Switch Tubing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFunction\u003c\/td\u003e\n\u003ctd\u003eCombustion Draft Safety Proving\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eICP \/ Tempstar \/ Heil\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch3\u003eCompatibility\u003c\/h3\u003e\u003cp\u003eDirect-fit for the ICP WPG4304060RKA1 and the Tempstar, Heil, and Comfortmaker furnaces built on the same platform.
