What Er31 Means
Er31 means the control board has no valid configuration data on hand — it's missing the setup information it needs to know which model it's running and how its zones are supposed to behave.
Common Causes of Er31
- A control board or induction module replaced without matching its configuration to this model
- A firmware or memory fault caused by a power interruption
- Boards or modules that were swapped between different cooktop or range models
🔧 One Safe Check You Can Try
Not a homeowner fix — loading the right configuration data requires a technician working through the proper service procedure for this exact model.
⚠ Why You Shouldn't Go Further Than That
- F&P's service documentation specifically warns technicians away from moving control boards or induction modules between different units, precisely because that's what generates this and related configuration errors.
- If the configuration data gets loaded wrong, a zone can end up operating on the wrong power profile entirely — a bigger problem than the fault it was meant to fix.
- On most models, getting to the boards means opening up the electronics bay under the glass surface, a step that frequently costs owners the rest of their warranty.
