Flame Sensor
The flame sensor is a safety probe that uses the physical property of flame ionization to prove the burner is lit. Over time, oxidation or silica buildup creates an insulating layer that prevents the control board from receiving the necessary DC microamp signal. When this signal is lost, the furnace shuts down the burners but continues to run the blower motor, resulting in the circulation of cold air.

Condensate Trap Kit
As a 96% AFUE unit, the EL296V produces significant condensation that must drain through a dedicated trap. If this trap becomes clogged with sediment or biological growth, the pressure switch will trip to prevent water from backing up into the inducer motor. This safety trip halts the ignition sequence while allowing the blower to continue running for ventilation.

Primary Limit Switch
This switch acts as a thermal safety that opens if the heat exchanger exceeds its calibrated temperature, often due to restricted airflow. When the limit opens, the control board is programmed to kill the burners immediately and run the blower at maximum speed to cool the internal components, causing the user to feel cold air at the registers.
