Applies to:
The unit has electronic spark ignition, that lights a standing pilot.
Two different modules are in the field. The White Rogers modules have a red LED, and the Robershaw modules have a green LED. These LEDs help to identify a failure.
For the White Rogers’ module, when the control calls for heat, the White Rogers LED will flash, then go out, indicating the control is functional. If the LED continues to flash, the module did not sense a pilot flame. If the LED stays on continuously, an internal fault has been detected, and the module should be replaced.
For the Robertshaw, when the control calls for heat, the LED will be on continuously, indicating the control is functional. If the LED flashes, the module did not sense a pilot flame. If the LED goes out while the control is calling for heat, an internal fault had been detected, and the module should be replaced.
