MC Enterprise 37057MC Furnace Igniter Electrode | 2-Prong Single Sense

Ensure your RV furnace stays lit with the MC Enterprise 37057MC Igniter Electrode. This high-quality aftermarket electrode is designed specifically for Atwood Hydro Flame furnaces. It serves as a "single sense" component, meaning it both generates the initial ignition spark and monitors the flame to ensure the gas valve stays open safely.

Over time, furnace electrodes can become "carbon-fouled" or the ceramic can crack, leading to "spark but no light" or "lights but goes out" scenarios. The 37057MC is the direct replacement to restore consistent heating performance.

Key Features

• Dual Functionality: Works as both a spark igniter and a flame sensor (single sense).

• High-Heat Ceramic: Engineered to withstand the extreme temperatures of the furnace burner box without cracking.

• Direct Fit: Includes the specific 2-prong configuration and mounting bracket for Hydro Flame 85 and 89 series.

• 2-Prong Design: Features a dedicated spark gap for reliable ignition in cold weather.
