Trane S8X1 80 Single-Stage Gas Furnace E08: Low flame current
The Trane S8X integrated furnace control table identifies E08 as low flame current that is still strong enough to allow operation.
Trane S8X1 80 Single-Stage Gas Furnace E11: Internal gas valve relay or valve error
The Trane S8X integrated furnace control table identifies E11 as a gas valve relay or gas-valve energizing error.
Trane S8X1 80 Single-Stage Gas Furnace E12: Open low-voltage fuse
The Trane S8X integrated furnace control table identifies E12 as an open fuse condition.
Trane S8X1 80 Single-Stage Gas Furnace E05: Flame detected when it should not be present
The Trane S8X integrated furnace control table identifies E05 when flame is detected while it should not be present.
Trane S8X1 80 Single-Stage Gas Furnace E6.1: Reversed voltage polarity
The Trane S8X integrated furnace control table identifies E6.1 as reversed voltage polarity.
Trane S8X1 80 Single-Stage Gas Furnace E6.2: Bad grounding
The Trane S8X integrated furnace control table identifies E6.2 as a grounding problem.
Trane S8X1 80 Single-Stage Gas Furnace E6.3: Igniter relay or open igniter fault
The Trane S8X integrated furnace control table identifies E6.3 as an igniter relay failure or open igniter condition.
Trane S8X1 80 Single-Stage Gas Furnace E7.1: Gas valve energized when it should be off
The Trane S8X integrated furnace control table identifies E7.1 when the gas valve is energized without the proper request.
Trane S8X1 80 Single-Stage Gas Furnace E2.1: Retry exceeded; flame never sensed
The Trane S8X integrated furnace control table identifies E2.1 as retries exceeded because flame was never sensed, resulting in a lockout condition.
Trane S8X1 80 Single-Stage Gas Furnace E2.2: Recycles exceeded; established flame was lost
The Trane S8X integrated furnace control table identifies E2.2 as recycles exceeded after flame was sensed and then lost repeatedly.
