Lennox Furnace: Clear stored error codes in the error recall menu
Clear stored error codes in the error recall menu on a Lennox furnace: The lowercase c in the error recall menu erases all stored codes; it must be confirmed while it flashes.
Applies to: Lennox EL296UHV, SL280UHV/SL280UHNV, SL297UHNV and ML180UHEK furnaces with 7-segment integrated control
How to fix clear stored error codes in the error recall menu: step by step
- Enter error recall by holding the button until E shows, then release.
- Scroll the recall menu until c shows (it changes about every 5 seconds).
- Press the button again while c is still flashing to delete all stored codes.
- Exit by holding the button until three bars show.
