Common Lennox Furnace Error Codes and What They Mean
Code 1 — Watchguard, Burners failed to ignite. This error most commonly arises from a problem with the furnace’s gas supply. But it can also be due to a faulty ignitor or an obstructed burner. A professional inspection might be needed if the basic checks don’t work.
Code 2 — Pressure switch open with the inducer on. This code can signify an issue with the pressure switch circuit or improper venting. It might help to inspect vent pipes for blockages and make sure the furnace’s drainage system is functioning well.
