A Munters P00140302 Flame Sensor confirms burner flame presence and relays status to the controls for dependable safety response in the HVAC system.
The flame sensor detects the presence of a burner flame and signals the control system to continue safe operation within the heating and cooling unit. Its precise construction matters because reliable sensing in high-heat conditions supports proper ignition monitoring and prevents unsafe fuel flow in the HVAC system.
The flame sensor may be failing if the heating and cooling equipment shows ignition problems, short cycling or intermittent burner shutdowns during operation. You might notice physical signs such as buildup, corrosion or discoloration on the sensor and environmental signs may include exposure to moisture, dirt or excessive heat that can affect performance.
