How to Read the Error Code

The integrated control module uses a tri-color LED (Green, Amber, Red) diagnostic system. The ignition control is equipped with a momentary push button switch that can display the last five faults detected. The control must be in Standby Mode (no thermostat inputs). To clear the fault code memory, push and hold the "LAST ERROR" button for more than 5 seconds and less than 10 seconds. Furnace lockout results when a furnace is unable to achieve ignition after three attempts during a single call for heat, characterized by a non-functioning furnace and a one flash diagnostic LED code.
