A photocell is a sensor used in burners to detect the presence of a flame. It monitors combustion and sends a signal to the control system to ensure safe operation. If the flame goes out, the photocell triggers a shutdown to prevent unburned fuel from accumulating. This component is critical for safety in gas and oil burners. Replacing a malfunctioning photocell is a common repair that enhances system reliability.
