Before you act

Code meanings are not universal.

HVAC & furnaces: These are technician-facing gas-furnace references, not repair guides. Do not open the furnace, test wiring or gas components, adjust combustion settings, or reset safety devices. Use a qualified HVAC professional; if you smell gas, leave the area and contact your gas utility or emergency services from a safe location.

These summaries describe the manufacturer's published explanation. They are not a remote diagnosis and do not establish that a specific component has failed.
