Jenn-Air JGS1450FS Gas Range 30 in 5.0 cu ft 18,000 BTU Gas Range with Even-Heat True Convection F3E3 Error Fix: Oven Sensor Reading Unrealistically High

Error code F3E3 on the Jenn-Air JGS1450FS Gas Range 30 in 5.0 cu ft 18,000 BTU Gas Range with Even-Heat True Convection means: Oven Sensor Reading Unrealistically High. The temperature sensor is reading an unrealistically high temperature while the oven should be cool — the sensor may be failing, the wiring may have a partial break (intermittent low resistance), or the connector may be corroded from moisture; measure sensor resistance at room temperature — should be approximately 1,080 ohms; values significantly lower indicate a failing sensor or partially shorted wiring; clean connector contacts and replace sensor if resistance is out of range
