Wolf Legacy Induction Range Code 31: Invalid configuration

What 31 means

On pre-2018 Wolf induction ranges such as the IR304TE/S/TH and IR365PE/S/PH, code 31 means the control found an invalid configuration. The saved setup that tells it which model and options it is running does not match what it expects. The display shows 31 and the range may refuse to heat. This often follows a control replacement or a memory problem.

Common causes of 31

Control board configured for the wrong model or option set
Configuration data lost or corrupted in the control
A recently replaced control that was not set up for this range

✓ One safe check you can try

1. Turn all elements off and clear the glass. 2. Flip the range breaker off, wait one minute, then flip it on. 3. Check whether 31 clears on restart. 4. If it stays, stop using the range and call us. Do not open the range or remove the control.

! Why to stop there

Configuration is set with technician tools, so there is no owner setting that fixes it.
Guessing at a part could install a control that is still wrong for the model.
We confirm the exact price in writing first and warranty the work for 30 days.

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.

3131 questions

What is an invalid configuration?

Code 31 says the control's saved model setup is not valid. The range does not know which options it should run. That is a control-level issue, not a problem with your pans or the glass.

Why did 31 show up after a repair?

A replacement control has to be set up for your exact model. If that step is missing or wrong, the range can show 31. A technician with the right tools can correct it.

Can I clear 31 myself?

A breaker reset is safe to try, but it rarely changes a stored configuration. If 31 returns, call us and we will quote the repair before any work starts.
