also known as the Model TCA-1 Thermocouple Adapter

providing reliable 24V secondary output infrastructure for modern climate control systems

this HI-limit lead wire ensures a reliable electrical path to interrupt gas flow should the system exceed its thermal safety setpoint

and cap required to convert the gas valve to natural gas operation

verifying the continuity of this high-limit safety switch is standard procedure for contractors ensuring safe combustion sequences

Lennox 80M29 Ignitor Els PW 17895 also known as the ModelThe Lennox 80M29 Ignitor is a heavy duty hot surface ignitor engineered for precise ignition in Lennox gas furnaces, as well as select Armstrong and Ducane heating systems. Functionally identical to the 80M2901 and often used as a direct OEM furnace replacement part for the 20434202 and 28M96, this component features a silicon nitride element known for superior thermal shock resistance compared to older silicon carbide versions. This 120V ignition
