Ashcroft B424VXG6-600 Pressure Switch 321042-401 Enhanced Durability: Conformal-coated circuitry provides

Enhanced Durability: Conformal-coated circuitry provides moisture resistance up to 95% relative humidity (non-condensing)

meaning flow is permitted when the coil is de-energized

especially on older high-efficiency units where diaphragm fatigue or port blockage is common

a full burner assembly replacement is necessary to ensure safe operation and prevent heat exchanger damage

Operating at a high voltage of 277Vac
