E2 on a Thermador Pro range means the gas safety system has shut off the valve, typically after repeated ignition failures or a detected pressure irregularity.
Step 1: Stop Attempting to Light It
Repeated ignition attempts without addressing the cause risk unburned gas accumulating briefly at the burner.
Step 2: Check for a Gas Smell
If you smell gas at any point, stop immediately, don’t attempt to relight, ventilate the area, and shut off the gas supply at the valve.
Step 3: Don’t Attempt Valve Repairs Yourself
Gas valve work involves both electrical and gas-line safety, and in most areas gas line work legally requires a licensed professional.
Step 4: Book a Diagnostic
A technician can confirm whether the issue is the range’s valve and ignition system or a home gas-supply pressure issue. Visit our range repair page.
