Local Sense Electrode Spark Probe — direct replacement ignition needle for Atwood RV electric water heaters. A accessory to restore reliable ignition and safe operation of RV hot water systems. Key benefits Restores reliable ignition: replaces worn or damaged spark probes to stop noignite or intermittent ignition failures. Improves safety: correct sparking helps burners light properly and prevents unsafe ignition behavior. Simple, costeffective : swap the old probe for this directfit part instead of replacing the whole unit. What it does Acts as the local sense electrode / spark probe (ignition needle) that creates the spark to ignite gas in Atwood RV water heaters. Designed to align with factory positions and gas flow for consistent performance on compatible models. Compatibility (fits these Atwood/Truma ignition models) Gch64e, Gch66e, Gch67e, Gch6a10e, Gc6aa10e, Gc6a7e, Gh63e, Gh64e, Gh66e, Gh67e, Gh68e, G6a2e, G6a3e, G6a4e, g6a8p, g6a6e, G6a7e, G6a8e, Gch6a7e, Gch6a8e, Gch6a9e, Gc6aa7e, Gc6aa8e, Gc6aa9e, Gch10a2e, Gch10a3e, Gc10a2e, Gc10a3e, G101e, Gh101e, G6103e, gh6103e, G102e, G103e, Gc101e, Gc102e, Gh102e, Gh103e, Gc10a4e, Gch10a4e, XT 6 and XT 10 spark ignition models. Important specifications and performance notes Function: local sense electrode / spark probe (ignition needle) for RV electric water heaters. Fit: direct replacement for the listed Atwood/Truma models (standard replacement size for those models). Performance: provides the spark path required for consistent ignition when clean and correctly positioned. Condition checks: probes must be clean and of cracks, flaking, or corrosion to perform correctly. Installation and testing (concise, stepbystep) Check the gap before installation: set the gap between the sparking probe and the ground probe to 1/8 inch. Position probes in the path of gas flow and ensure they are clean and undamaged. To test sparking: remove the gas valve from the circuit, turn the unit on, and observe the spark behavior. If you see a spark jumping from the ceramic to the ground rod or bracket, the spark probe. Installation is straightforward: remove the old igniter and install the probe in the original position. If unsure, search for modelspecific installation videos for guidance. Maintenance tips Inspect probes during routine service or before each travel season. Clean gently with a soft cloth—do not file or sand the ceramic. if you find cracks, heavy corrosion, flaking, or inconsistent sparking. Typical use scenarios 1) a failed igniter on an Atwood RV water heater that won't light or has intermittent ignition, restoring hot water quickly. 2) Perform preventive maintenance before a long trip or camping season to avoid roadside repairs and ensure safe burner ignition. 3) Troubleshoot intermittent sparking: swap in this probe to isolate ignition failures and confirm whether the spark source or another component needs service. What to expect in the box One Local Sense Electrode Spark Probe (ignition needle) designed for the listed Atwood models. If your water heater model is on the compatibility list above, this probe is a directfit replacement to restore ignition performance and improve safety without replacing the entire heater.
