Jenn-Air Range Error Code F3E0

F3E0 on a Jenn-Air range means the oven temperature sensor circuit has been detected as open or shorted. The oven sensor is an RTD probe that monitors cavity temperature by varying its electrical resistance. When the control board cannot read a valid signal from this sensor, it triggers F3E0 and disables oven operation. The issue can originate at the sensor probe, the wiring harness, or the connectors between the sensor and the control board.

No, it is not safe to use the oven while F3E0 is active. Without a working temperature sensor, the control board cannot regulate oven heat accurately, which creates a risk of overheating. The surface burners on a gas or electric range may still function, but the oven should not be used until the fault is resolved.

Repair costs depend on which component has failed. A replacement oven temperature sensor probe typically costs between $20 and $75 for the part alone, making it the most affordable fix. If the wiring harness needs replacement, parts and labor could range from $100 to $250. A faulty control board is the most expensive scenario, with total repair costs potentially ranging from $200 to $500 or more depending on the model and labor rates in your area.

A knowledgeable DIYer can diagnose this code using the built-in Diagnostic Mode by navigating to STATUS SCREEN > OVEN SENSORS to check for a live temperature reading. If the sensor is faulty, replacing the oven temperature sensor probe is a relatively straightforward repair on most Jenn-Air ranges. However, if the wiring harness is burned or the control board is suspect, professional repair is recommended to avoid further damage.

Resetting the range by cutting power at the breaker for a few minutes may temporarily clear the F3E0 code, but the error will return if the underlying sensor or wiring fault still exists. A reset is useful for confirming whether the fault is intermittent or persistent, but it does not fix the root cause. A proper diagnosis using Diagnostic Mode is needed to determine if a component replacement is required.
