RV Water Heater Ignition Control Board 520814 for Suburban SW6D SW6DE 12V Reliable PlugandPlay Replacement

Replacement Ignition Control Module Board for 12 Volt DC Furnaces and Water Heaters Overview This ignition control module is a direct replacement for common 12 Volt DC furnace and water heater control boards. It produces the voltage spark, controls gas valve current, and monitors flame sense signals to restore reliable ignition and safe operation in compatible units. Key benefits Reliable ignition: Precisionengineered circuitry provides consistent voltage sparking and flame sensing to eliminate nospark and failed ignition events. Safe operation: Regulates gas valve current and monitors flame signals; the unit attempts ignition up to three times before locking out to prevent gas buildup. Built for harsh conditions: temperatureresistant printed circuit board tolerates typical furnace and water heater environments for dependable performance. Fast replacement: Plugandplay design requires no rewiring. Swap the board in minutes to the system to service. Features Function: voltage spark generation, gas valve current regulation, and flame sense monitoring. Ignition control: 3trial ignition sequence with lockout after failed attempts. Material: temperatureresistant PCB. Power: Designed for 12 Volt DC systems used in mobile and stationary applications. Direct replacement for part numbers: 520871, 520814, 520820, 33550L, AP4896608. Compatibility Compatible with Suburban furnace and water heater circuit boards including 520871, 520814, 520820, 33550L, AP4896608. Fits SW series water heaters with serial numbers above 953900766. Fits the following models: SW4D, SW6D, SW6DE, SW6DEL, SW6DEM, SW6DM; SW10D, SW10DE, SW10DEL, SW10DEM, SW10DM; SW12D, SW12DE, SW12DEL, SW12DEM; SW16D, SW16DE, SW16DEL, SW16DEM. Suitable for use in 12 Volt DC water heaters, furnaces, and refrigerators. Problems it fixes No spark or failed ignition. Intermittent flame outages or unreliable flame sensing. Heater shortcycling where the unit shuts off after a few seconds. Unresponsive control systems that do not initiate or regulate ignition. Package contents 1 x 520814 Ignition Control Module Board Installation notes Plugandplay replacement; no rewiring required. Verify the appliance model and serial number before to confirm compatibility, especially for SW series water heaters with serial numbers above 953900766. Use scenarios 1) RV water heater that will not light: the failed ignition board to restore reliable spark generation and flame sensing without rewiring. 2) Mobile furnace that shortcycles or fails to maintain flame: Install the module to correct ignition sequencing and prevent repeated unsuccessful gas valve openings. 3) 12 Volt refrigerator or auxiliary heater with intermittent flame signal: Swap the board to recover stable flame detection and consistent operation. Technical reminder Confirm model and serial number compatibility prior to installation. This module is intended as a direct replacement for the listed part numbers and specified SW series models.
