Possible Causes

Open oven temperature sensor, Broken sensor wiring, Loose connector at EOC

Safety first: Disconnect power at the breaker before testing.

Test sensor: Access and disconnect the oven temperature sensor. Measure resistance at room temperature; if open (OL) or far from 1050–1100 Ω, replace the oven temperature sensor.
Check harness: Inspect wiring from sensor to EOC for breaks or burnt spots. Repair or replace as needed.
Control board: If sensor and wiring are good, the EOC sensor circuit may be faulty; replace the electronic oven control.
