American Standard Furnace Code E2.2

Hard lockout

Recycles exceeded. The burner lit but the flame was lost during the cycle, ten times, so the control locked out for one hour.

Manual wording: “Recycles Exceeded (Flame sensed then lost, one hour lockout after 10 times)

Documented for: A951X condensing and A801X induced draft furnaces with the seven-segment IFC display

Likely causes, most common first

  1. Flame sensed then lost, ten times
  2. Marginal flame signal or dirty flame sensor
  3. Low or unstable gas pressure
  4. Restricted venting causing the burner to be starved

What you can safely check yourself

  • Change your filter if it is dirty
  • Look for snow, ice, weeds, or grass blocking the furnace venting
  • Reset once by turning the furnace switch off and back on

When to call a technician

Repeated flame loss is a burner, flame sensor, gas pressure, or venting problem. Have a technician diagnose it rather than resetting repeatedly.

A American Standard furnace throwing this code repeatedly has a reason — clearing the code without fixing the cause just hides it.
