Jenn-Air JGS1450DS Slide-In Gas Range F3 Error Fix: Oven Temperature Sensor Open or Shorted

Error code F3 on the Jenn-Air JGS1450DS Slide-In Gas Range means: Oven Temperature Sensor Open or Shorted. The RTD (Resistance Temperature Detector) oven temperature sensor circuit is reading open or shorted — the sensor should read approximately 1,080 ohms at 72°F (22°C) and increases with temperature; check the sensor wiring harness and connector at the back of the oven for damage, corrosion, or loose connections; the sensor wire runs inside the oven cavity and is subject to extreme heat which can embrittle insulation and cause breaks; measure resistance at the ERC connector with the sensor disconnected; if the reading is open (infinite) or near zero, replace the oven temperature sensor; the sensor is typically a probe inserted through the rear oven wall
