Stop nuisance short cycling and ignition lockouts on your Goodman ADSS800804BXAD furnace with this genuine OEM flame sensor. The flame sensor (flame rod) uses flame rectification to confirm the burners have lit; if it fails to detect flame within a few seconds, the control board shuts off the gas valve for safety. A dirty, cracked, or worn sensor is the single most common cause of a furnace that lights briefly then shuts down.
Our OEM Goodman sensor uses the correct rod alloy and length to generate a stable microamp signal your control board can read reliably. Generic sensors often produce marginal flame current that triggers intermittent lockouts. When your furnace's uptime depends on a clean signal, choose OEM.
Easy (1/5). One of the simplest furnace repairs — turn off power, remove one mounting screw, unplug the single wire, and install the new sensor. About 10 minutes with a nut driver. Avoid touching the rod with bare fingers, and confirm the burner igniter/sensor orientation before powering up.
