Dometic 91606 RV Water Heater Spark Probe (Dual Electrode)

Ensure your water heater fires up every time with the Dometic (Atwood) 91606 Spark Probe Assembly. This dual-electrode igniter is the component responsible for creating the high-voltage spark that lights the main burner. Over time, these electrodes can become carbon-fouled, cracked, or out of alignment, leading to "lockout" errors where the heater tries to light but fails.

This is a genuine Post-Style electrode, commonly referred to as the "Old Style" or "Standard" DSI igniter. It includes the ceramic insulators and the mounting bracket designed to sit perfectly over the burner tube slots for optimal ignition.

Key Features

• Reliable Ignition: Dual-probe design provides a consistent spark gap for immediate gas ignition.

• Direct OEM Fit: Exact replacement for most 6 and 10-gallon Atwood/Dometic DSI units.

• High-Heat Ceramic: Durable insulators prevent electrical arcing and withstand the intense heat of the combustion chamber.

• Easy Installation: Single-screw mounting and a standard spade-post connection for the ignition wire.
