RTD Temperature Sensor Probe
The RTD probe is a thermistor that provides the control board with real-time temperature data via resistance changes. If the internal ceramic or wire filament degrades, it can send a high-resistance signal interpreted as a low temperature, triggering the 'Ler' safety shutdown. Replacing the probe restores accurate thermal feedback to the D2 controller.

Induction Fan
The induction fan is responsible for the oxygen-to-fuel ratio within the fire pot. If the fan motor experiences winding failure or the impeller is obstructed, the fire will smother or fail to reach 'high-fire' status during start-up. This results in a genuine low-temperature condition that the system identifies as a combustion failure.

D2 Controller Board
The D2 controller processes signals from the RTD to modulate the auger and fan speeds. If the onboard logic processor or the RTD signal-to-digital converter fails, it may incorrectly trigger a 'Ler' code despite nominal sensor data. This is typically considered only after the probe and fan are confirmed functional.
