Quick Assessment
Answer to continue safely
Is it safe to keep using?
No. A gas valve control fault is a high-severity safety concern. The rangetop must not be operated until the valve control circuit is diagnosed and repaired by a qualified gas appliance technician.
Can I reset the code?
No. E3 indicates a hardware fault in the gas valve control circuit that a reset will not correct. Professional diagnosis and likely component replacement are required before the rangetop can be safely operated.
When to stop immediately?
Stop if you notice: A burner flame does not extinguish when the knob is turned to off — shut off the gas supply immediately., You smell gas with no burners intentionally on..
Symptoms You May Notice
Burner flame does not extinguish when knob is turned off
Turning a burner knob to the off position fails to extinguish the flame, indicating the electronically controlled gas valve is not closing in response to the control board's command.
E3 code appears on the rangetop control display
The fault code E3 is displayed on the control panel, and in some configurations the affected burner indicator flashes to identify the specific valve circuit involved.
Burner ignites spontaneously without knob input
In rare cases a stuck-open valve fault can allow gas to flow to the burner unprompted, with the igniter potentially lighting it without user action — a serious safety event.
Burning smell or sooting around burner base
Partial valve opening due to a control fault can produce an irregular flame pattern that burns outside the designed combustion zone, leaving soot deposits on the rangetop surface or grate underside.
Possible Causes
Failed gas valve solenoid
The electromagnetic solenoid coil inside the gas valve has failed open or closed, preventing the valve from responding to control board commands. This requires valve replacement by a qualified technician.
Requires ProfessionalControl board valve driver circuit fault
The output driver circuit on the main control board that sends the activation signal to the valve solenoid has failed, meaning the valve itself may be intact but receives no usable command.
Requires ProfessionalWiring harness fault between board and valve
A broken wire or loose connector in the harness running from the control board to the valve solenoid interrupts the control signal, causing the board to detect a non-responsive valve and raise E3.
Requires ProfessionalSafe Checks You Can Do
-
1
Turn off the gas supply immediately
If a burner flame will not extinguish or you suspect a stuck-open valve, immediately turn off the dedicated gas shut-off valve behind or below the rangetop. Do not attempt to reset or troubleshoot the appliance with gas flowing.
Locate and become familiar with the gas shut-off valve location before any fault occurs so you can act quickly in an emergency.
-
2
Ventilate the kitchen
Open windows and the range hood damper to clear any accumulated gas from the kitchen before performing any further steps. Wait at least five minutes after the gas supply is shut off.
Do not operate any electrical switches, including the range hood fan, until you are confident no gas has accumulated — sparks from switch contacts can ignite gas.

3
Perform a control board reset only if safe to do so
Only after confirming no gas is present, perform a 60-second circuit-breaker reset. Do not restore the gas supply until the rangetop is confirmed fault-free or until a technician has inspected the valve circuit.
If E3 returns immediately after reset, leave the gas supply closed and schedule immediate professional service.
When to Call a Professional
Contact a qualified technician if:
- The gas valve solenoid coil measures open circuit or short circuit when tested.
- The control board shows burn marks or heat damage near the valve driver output terminals.
- The wiring harness to the valve shows chafing, heat damage, or broken conductors.
