Diagnosis

Ignition, flame-proving or gas-control faults require professional diagnosis; replacing this component will not correct every no-heat condition.

Installation guidance

A qualified gas-service technician must perform installation. Isolate electrical power and fuel, verify the exact control revision, gas type, ratings, sensing arrangement and equipment wiring diagram, and follow the equipment-specific service procedure. Never bypass flame-safety controls, improvise wiring or change gas regulation without approved instructions. Complete required leak, ignition and combustion checks before returning equipment to service.

This is preparation guidance, not a complete model-specific repair procedure.
