It sequences spark, gas valve, and flame sensing for the water heater burner. No-spark or lockout faults with good supply trace here once the electrode tests good.

Technical Construction & Specifications
The board is manufactured to OEM specification for the 91367 interchange with matched timing, sensing, and protection behavior. Terminal layout mirrors the original for direct connection transfer. Standard warranty coverage applies.
Installation & Maintenance Guidelines
Shut off gas and power first. Photograph the wiring, transfer plugs one at a time, and secure the board on its mounts. Leak-test gas connections with approved method, restore power, and verify ignition plus steady burner operation.
