Lennox 14A53 Pressure Switch 318518-761 you know that consistent combustion

you know that consistent combustion depends on the element reaching a precise ignition temperature of up to 1800°F (982°C)

allowing for easy capacity adjustments via exchangeable orifice assemblies

providing critical end-stop feedback or the ability to trigger external equipment like pumps or fan coils

This is a 208/230V

The inclusion of the locking collar allows for a secure

Lennox 14A53 Pressure Switch 318518-761 you know that consistent combustionThe 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
