Wolf Legacy E Series Code Error 01 x 0: Temperature sensor circuit open

What Error 01 x 0 means

Older Wolf E Series wall ovens in the SO30TE/S/TH and DO30TE/S/TH generation display Error 01 x 0 when the oven temperature sensor (RTD) reads open, as if its circuit were broken. The control cannot read the cavity temperature, so heating usually stops and the code stays on the display. The x in the code stands for the cavity digit, so check which oven it names.

Common causes of Error 01 x 0

Oven temperature sensor (RTD) open or disconnected
Sensor wiring or connector not making contact
Control not reading the sensor circuit

✓ One safe check you can try

1. Shut the oven off and give it time to cool down completely. 2. Make sure nothing is stuck in the door or against the back wall of the cavity. 3. Turn the breaker to off for sixty seconds and then to on. 4. Start a short bake. If Error 01 x 0 returns, stop using the oven and call us.

! Why to stop there

The sensor and its wiring are inside the oven cavity wall and behind panels, where owners should not reach.
An open reading can come from the sensor, a connector, or the control, and only a meter test tells them apart.
We test first and quote in writing before any part is ordered.
If our work does not hold within 30 days, we come back.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

Error 01 x 0Error 01 x 0 questions

What is an RTD?

It is the resistance temperature detector, the sensor the control uses to know how hot the oven is. Open means the control sees a broken circuit instead of a normal reading.

Will the oven still bake?

Normally not. Without a temperature reading the control cannot hold a setpoint safely, so it stops heating and leaves the code showing until a technician checks the circuit.

Is the x a typo?

No. The x is the cavity digit, so a double oven shows which cavity has the open sensor, and we use it to start at the right place.
