Ao Smith 100110701 Flame Rod Heating Control

Product Description

The AO SMITH 100110701 is a flame rod designed for use in heating systems as a flame-sensing control component. A flame rod works by completing a low-current electrical circuit through the burner flame, allowing the control board to verify ignition and maintain safe system operation. If flame is not detected within the trial-for-ignition period, the control shuts off the gas valve to prevent unburned fuel accumulation. This part is typically installed by licensed HVAC technicians or qualified heating contractors during routine service or component-level repair.

The 100110701 flame rod is suited for residential and light-commercial heating applications. It functions within the burner assembly, positioned to pass through or alongside the flame envelope during normal operation. Replacement is commonly required when the rod develops carbon buildup, corrosion, or cracking that degrades the microamp signal returned to the control board, causing nuisance lockouts or failed ignition sequences.

Key Features

• Functions as a flame-sensing electrode to confirm burner ignition
