Jenn-Air JGS1450DS Slide-In Gas Range F4 Error Fix: Oven Temperature Sensor Open Circuit

Error code F4 on the Jenn-Air JGS1450DS Slide-In Gas Range means: Oven Temperature Sensor Open Circuit. The RTD sensor circuit is reading open (infinite resistance) — this is often a broken wire in the sensor harness or a disconnected plug rather than a sensor element failure; check all connections between the sensor and the ERC board; check for wire damage where the harness passes through the oven insulation; on some Jenn-Air models F3 and F4 are combined into a single code; if wiring is intact and connections are secure, replace the temperature sensor
