How to Read the Error Code

Refer to the Troubleshooting Codes for assistance in determining the source of unit operational problems. The dual 7-segment LED display will display an error code that may contain a letter and number. The error code may be used to assist in troubleshooting the unit. Furnace lockout results when a furnace is unable to achieve ignition after three attempts during a single call for heat. It is characterized by a non-functioning furnace and a E0 code displayed on the dual 7-segment display. Accessing the furnace's diagnostics menu provides ready access to the last ten faults detected by the furnace. Faults are stored most recent to least recent. Any consecutively repeated fault is stored a maximum of three times.
