Jenn-Air Oven Error Code F3E9-0

F3E9-0 means the meat probe temperature sensor in the secondary oven cavity has a short circuit condition. The control board has detected an abnormally low resistance in the probe circuit, which indicates a failed probe, damaged wiring, or a faulty receptacle. The oven flags this fault to prevent incorrect cooking based on a bad temperature reading.

If only the secondary cavity is affected and the oven still allows operation in the primary cavity, you can use that function with caution. However, you should not ignore this fault, as a shorted probe circuit can interfere with cooking accuracy. Avoid using the meat probe feature in the secondary cavity until the fault is diagnosed and repaired.

If the meat probe itself is the cause, replacement probes typically cost in the range of $30 to $80 depending on the model. A probe receptacle replacement, including parts and labor, generally runs between $100 and $200. If the main control board needs replacement, costs can range from $200 to $450 or more for parts and professional labor.

Start by entering Diagnostics mode and verifying that the probe reads within the expected range at room temperature (50°F to 90°F). Unplug the meat probe from the secondary cavity and check whether the error clears. If it does, the probe is likely shorted and should be replaced. If the error persists with no probe connected, inspect the receptacle and wiring harness for damage or contamination.

A power reset by turning off the circuit breaker for one to two minutes may temporarily clear the fault, but if the underlying short circuit condition remains in the probe, receptacle, or wiring, the code will return. A reset alone is not a fix and should only be used as part of diagnosing whether the fault is intermittent or persistent.
