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 problem 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 problem it was meant to fix.
- On most models the boards sit under the glass on harnesses cut short, so lifting the top further than those leads allow pulls connectors straight off the boards.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
