Lennox 14A53 Pressure Switch 319848-301 making it an essential componentThe Lennox 14A53 Pressure Switch is a critical safety component designed for two stage gas furnaces, specifically engineered to monitor dual pressure thresholds of . 40" WC and . 70" WC. As a vital furnace draft inducer switch, it ensures the combustion blower is moving sufficient air to clear flue gases before ignition occurs. This dual stage pressure switch prevents hazardous operation by opening the electrical circuit if the static pressure falls
