Wolf Legacy E Series Code Error 07 0 35: Relay module ambient thermistor open

What Error 07 0 35 means

Error 07 0 35 appears on Wolf Legacy E Series wall ovens such as the SO30TE/S/TH as RM Ambient Thermistor Open. The thermistor that reads temperature near the relay module looks like a broken circuit to the control. The oven may stop or limit use, and the code stays on the display. A literal 0 sits in the middle, so the message concerns the control as a whole.

Common causes of Error 07 0 35

Ambient thermistor on the relay module open
Thermistor wire or connector not making contact
Relay module failing

✓ One safe check you can try

1. Shut the oven off and give it time to cool down completely. 2. Make sure the vents around the oven are clear and the kitchen is not extremely hot. 3. Turn the breaker to off for sixty seconds and then to on. 4. If the display shows Error 07 0 35 once more, stop and call us.

! Why to stop there

The thermistor sits on the relay module inside the control area, not within owner reach.
Open can mean the sensor, its wire, or the board, and a meter is needed to tell.
We quote in writing before any part is ordered.
A 30-day warranty on workmanship comes with the repair.

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 07 0 35Error 07 0 35 questions

What does the ambient thermistor measure?

It measures the temperature around the relay module, so the control knows how hot its own electronics are. Open means that reading is missing. Most owners are surprised how fast this goes once we know the cause.

Is it related to Error 07 0 36?

Yes. Error 07 0 35 says the same thermistor reads open, and Error 07 0 36 says it reads shorted, so both point to the same part and its circuit.

Can a hot kitchen cause it?

Heat alone should not make a sensor read open. Still, clear vents help the electronics, and if the code returns after a reset we test the thermistor circuit.
