Why is my Goodman Furnace induced draft blower and circulator blower running continuously?

  Patricia GarzaAug 31, 2025
  If the induced draft blower and circulator blower run continuously with no furnace operation, it may be due to flame sensed with no call for heat, a short to ground in the flame sense circuit, a lingering burner flame, or a slow closing gas valve. Correct the short at the flame sensor or in the flame sensor wiring and verify proper operation of gas valve.
