Trane KIT15331 Pressure Switch 320788-702 and diaphragm components necessary toThe Trane KIT15331 Pressure Switch is a specialized high altitude conversion kit designed to maintain precise combustion analysis and safe furnace operation at elevations typically exceeding 4,000 feet. At these altitudes, the lower air density results in insufficient negative pressure for standard factory switches, which can lead to nuisance lockouts, pressure switch errors, and unreliable draft inducer performance.
