What F3 Means
F3 is a shorted oven sensor on the classic ERC. Dacor notes the check happens only while a cooking operation is being attempted and needs 16 short readings in a row, so the code shows when you start the oven, not while the range sits idle.
Common Causes of F3
- Sensor shorted
- Sensor wiring damaged at the back of the oven
🔧 One Safe Check You Can Try
Cancel, let the oven cool, and look at the sensor inside the cavity. Beyond that, service is needed.
⚠ Why You Shouldn't Go Further Than That
- The sensor connection is behind the range, which has to be pulled out.
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.
