Flame Sensors
Available22 products
Flame sensors install into combusting heating systems, detect the presence of flames, and send a signal that the ignition control system uses to regulate the combustion process. Some units have contacts that switch when exposed to flame, while others provide the raw signal for the control to interpret.
Universal Replacement Flame Sensors
Universal replacement flame sensors are installed into a wide range of combustion heating systems, detect the presence of flames, and send a signal to the control board. They are not OEM (original equipment manufacturers) parts and may require adapters or rewiring to connect to existing components.

OEM Direct Replacement Flame Sensors
OEM (original equipment manufacturers) direct replacement flame sensors are installed into specific models of combustion heating systems, detect the presence of flames, and send a signal to the control board. They are identical to the OEM parts and minimize the time and effort needed for installation.

Mercury Flame Sensors
Mercury flame sensors detect the presence of flames and activate a connected relay in response. As the flame heats the sensor, the mercury expands and switches a connected relay. This allows them to control higher voltages and currents than other flame sensor types.
