✓NOTE: If the unit is connected but not working (no igniter spark, no voltage, or board not functioning), the issue is most likely poor contact between the board connector and the water heater slot. 1. Clean the slot with a brush to remove dust. 2. Wipe the board connector with a dry cloth, eraser, or a small amount of alcohol — tin-plated contacts oxidize easily. Do NOT use a wet cloth or get the area wet. 3. Reinstall the connector perfectly aligned with the slot; even slight misalignment causes failure. This will solve the problem.If the first attempt does not work, please try the cleaning and installation steps several times — most issues can be resolved with repeated careful attempts.
