Trust this 239-46553-01 sensor to deliver consistent

an open circuit typically indicates a broken coil or a tripped non-resetting thermal limit

A trip at this threshold typically indicates restricted flue venting

it simplifies service calls by replacing dozens of legacy Honeywell and competitive models

Durable Construction: Heavy-gauge copper tubing ensures protection against mechanical damage and thermal stress in the combustion chamber

Utica-Dunkirk PB-001.01 Spark Pilot 30067439-890 Trust this 239-46553-01 sensor toThe Utica Dunkirk PB 001. 01 Natural Gas Spark Pilot is a heavy duty, field proven ignition component engineered for high performance gas boiler systems. Functionally identical to the Honeywell Q348A1002, this pilot burner assembly is designed for intermittent pilot ignition systems where reliability and precise flame sensing are non negotiable. It features a 1 inch batwing tip style (dual wing) and is factory equipped with a 0. 022" NE22 orifice
