Carbon monoxide is invisible and lethal. Confirm a working CO detector is on every floor. Shut off gas at the valve and the 120V breaker before opening the burner compartment.
Deposit recommendation
Igniters ($25–$80) and flame sensors ($10–$30) are no-deposit DIY parts. Replacing a control board ($150–$400) — keep your model & serial photo for warranty claims.
