Answer to continue safely
Is it safe to keep using?
No. F7 is a gas safety fault. Do not use the range until a qualified gas appliance technician has confirmed that the gas valve is seating properly and the E.R.C. relay is not stuck. This fault presents a risk of uncontrolled gas release and potential fire.
Can I reset the code?
No. Do not attempt to reset F7 if gas odour is present. Even without odour, a power-cycle only clears the displayed code — the gas valve or relay fault will cause F7 to return or, worse, will allow gas to continue flowing without displaying a fault. Professional inspection is required.
When to stop immediately?
Stop if you notice: Any gas odour present — close manual gas shutoff immediately, Oven cavity temperature continues to rise after shutoff.
Symptoms You May Notice
F7 displayed after oven is commanded off
The E.R.C. detects that the oven burner is still alight (via the flame sensor or RTD temperature rise) after the gas valve was commanded to close.
Gas odour after range is switched off
Raw gas smell persisting after the oven is turned off suggests the gas valve is not fully seating.
Oven cavity continues to heat after shutoff
Oven temperature continues to rise after a bake cycle is ended, indicating ongoing gas combustion.
Possible Causes
Gas safety valve stuck open or not seating
Debris or thermal deformation has prevented the gas valve solenoid from fully closing, allowing gas to continue flowing to the oven burner.
Requires ProfessionalE.R.C. gas valve relay stuck closed
The relay on the control board that powers the gas valve solenoid has welded shut, permanently supplying power to the valve and keeping it open.
Requires ProfessionalFalse positive from flame sensor or RTD
A failed flame sensor or drifted RTD may report ongoing combustion when the burner has actually extinguished, causing a false F7 fault.
DIY PossibleSafe Checks You Can Do
-
1
Shut off gas supply to the range immediately
If F7 appears and you detect any gas odour, close the manual gas shutoff valve behind the range immediately. If the odour is strong, evacuate and call the gas utility from outside.
The manual shutoff valve handle is perpendicular to the pipe in the closed position and parallel in the open position.

2
Do not reset or power-cycle with gas odour present
If gas odour is present, do not attempt to reset the range or operate any electrical switches — creating a spark near accumulated gas can be dangerous. Ventilate first.
Wait at least 15 minutes after ventilating and confirm no gas odour before attempting any further troubleshooting.
-
3
Check for a false positive (no gas odour present)
If F7 appears but no gas odour is detectable and the oven cavity is not heating after shutoff, power-cycle the range and monitor for recurrence. Test the RTD sensor resistance to rule out a drifted sensor causing a false flame-present reading.
A false F7 caused by a drifted RTD is rare but possible — confirm by verifying the oven actually cools normally after shutdown.
Tools required
When to Call a Professional
Contact a qualified technician if:
- Gas valve replacement requires certified gas appliance technician and gas line disconnection
- E.R.C. relay replacement requires board work with high-voltage components
- Any confirmed gas leak — gas utility involvement required before repair
