What Flt0A Means
Flt0A on the RNTT365GB clock display means all burners are locked. Every burner has hit its ignition lockout.
Common Causes of Flt0A
- Gas supply off or interrupted
- Igniters wet after cleaning
- Control or valve problem
🔧 One Safe Check You Can Try
Try to reset the burners as the manual explains. If the panel will not reset, unplug the cooktop for 10 seconds and reconnect. If the code clears, check the no-flame items before cooking again; if it continues, unplug and call for service.
⚠ Why You Shouldn't Go Further Than That
- When every burner locks, a supply or control problem is likely, and that needs gas-qualified diagnosis.
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.
