The Dometic DSI Igniter Wire Assembly (Part# 37419) is a critical 24-inch replacement wire that connects your RV refrigerator or water heater's control board to the igniter electrode. When this wire fails due to wear, heat damage, or corrosion, your appliance won't ignite properly, leaving you without cooling or hot water. This genuine OEM replacement restores reliable Direct Spark Ignition (DSI) operation in Dometic and Atwood appliances.
This 24-inch wire assembly is specifically designed for RV applications where space is tight and vibration resistance is essential. If you're experiencing intermittent ignition, clicking without lighting, or complete ignition failure, a damaged igniter wire is often the culprit.
