Utica Boilers Flame Sensor Parts

Overview

The Utica Boilers 550003151 Flame Sensor Kit is a genuine OEM replacement component designed for use in Utica Boilers heating systems. Flame sensors play a critical role in the safe and reliable operation of gas-fired boilers and furnaces. The sensor monitors the burner flame during each heating cycle. When the burner ignites, the flame sensor detects the presence of a live flame by measuring a small electrical current passed through the flame itself. If no flame is detected within a set time after ignition, the control board shuts down the gas valve to prevent unsafe conditions. This safety function protects both the equipment and the occupants of the building. Over time, flame sensors accumulate oxidation and carbon deposits on the sensing rod, which reduces electrical conductivity and causes nuisance lockouts or no-heat calls. Replacing a worn or fouled flame sensor with a fresh OEM kit like the Utica Boilers 550003151 restores proper flame detection and prevents repeat service calls. HVAC technicians and boiler service professionals rely on genuine replacement parts to maintain factory performance and warranty compliance. This kit includes the components needed for a straightforward swap during routine maintenance or emergency service. It is compatible with the Utica Boilers product line it was engineered for, ensuring a correct fit without modification. Keeping a flame sensor kit on the service truck reduces downtime on no-heat calls. This is a common wear item in…
