What F3E0 Means
F3E0 means the oven's temperature sensor (RTD probe) is reading as open - the control isn't getting a valid signal from the sensor it depends on to manage bake and broil temperature, distinct from the shorted-sensor reading of F3E2.
Common Causes of F3E0
- A failed oven temperature sensor (RTD probe)
- A damaged or disconnected sensor wiring harness
- A connector at the sensor or control board that has corroded or worked loose
🔧 One Safe Check You Can Try
Power the oven down at the breaker for a minute and restore power to see if the code clears - if F3E0 returns immediately once a cycle starts, that points to a genuine sensor or wiring fault.
⚠ Why You Shouldn't Go Further Than That
- Telling a genuinely failed sensor apart from a loose connector requires continuity testing on a de-energized oven, not a visual inspection.
- The sensor sits inside the cavity, and disconnecting it without knowing the correct routing can damage the wiring harness further.
- Reaching the sensor wiring typically means removing a rear panel, which can put remaining warranty coverage at risk if it isn't done by an authorized technician.
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.
