LED ON Amber LED steady on
What the display is showing
The amber status LED on the control (visible through the blower door sight glass) is lit and not flashing. It is one of three LED states the control uses, the others being rapid flashing and a two-digit flash code. A steady LED means the control has power and is not reporting a fault; on the 59TP6A it is what you see once the stored-code recall is finished and means normal operation.
Applies to: 59TP6A and 58SB0A/58SB1A furnaces (amber status LED control)
