7 flashes = Gas valve internal fault. The gas control valve has detected an internal failure — typically the solenoid coil, modulation circuit, or one of the integrated sensors. Replacement is dealer-only.
What this means
The gas valve is the integrated component that includes:
- Main gas solenoid (controls flow to the burner)
- Pilot solenoid (controls pilot gas)
- Thermostat (water temperature sensing)
- ECO safety (high-temp cutoff)
- FVIR sensor (flammable vapor detection, if equipped)
- LED indicator (the flash code you\'re reading)
When 7 flashes appears, the gas valve\'s internal self-test has detected a fault in one of these components.
Common scenarios
- Power surge damage: recent storm or breaker issue. Check other electronics
- Water damage: condensation or leak has reached the valve electronics
- Insect damage: ants or wasps in the burner area can damage internal wiring
- End of service life: gas valves typically last 12-15 years; failure is common on older units
Reset attempts
Try Level 1 reset (gas valve cycle). If 7 flashes persists:
- Cycle gas valve through off → pilot → on three times
- If still 7 flashes, the valve is genuinely failed
- Call State support or installer
Replacement cost
- Gas valve assembly: $200-400 OEM, model-dependent
- Labor: $250-500
- Total: $450-900
Inside warranty
Gas valve is covered under the 6-year ProLine / 8-year XE / 10-year Premier Hybrid parts warranty. Inside warranty, State ships the part to a State-authorized installer; you pay labor (after year 1).
Replace valve or replace unit?
If unit is 8+ years old, gas valve replacement at $450-900 approaches 50% of new-unit cost. Most installers recommend new unit at that point. Inside warranty — always replace the valve.
Bottom line
7 flashes = dealer call. Not a DIY repair. For older units (8+ years), consider replacement instead of repair.
