Flame Sensor
The flame sensor uses a Kanthal rod to detect ions within the flame, completing a DC rectification circuit. Over time, oxidation or silica buildup creates an insulating barrier that prevents the microamp signal from reaching the control board. The system initiates a safety shutdown when it fails to verify flame presence within the allotted timing window.

Integrated Furnace Control Board
If the flame sensor is clean but the E227 error persists, the logic gates on the control board responsible for interpreting the microamp signal may have failed. This prevents the board from recognizing a valid flame even when the physical sensor is functioning correctly.

Condensate Trap Kit
In high-efficiency units like the EL296V, a partial blockage in the condensate drainage can cause water to back up into the secondary heat exchanger or inducer housing. This can momentarily trip the pressure switch or splash onto the burners, causing an immediate flame dropout shortly after ignition.
