Oven overheats significantly beyond the set temperature; food burns quickly.

Safety first: Turn off power and gas immediately if the oven overheats uncontrollably. Allow to cool fully before inspection.

• Check control setting: Confirm the oven is not accidentally set to broil or a high temperature.
• Test sensor: On electronic models, test the oven temperature sensor resistance at room temperature. Replace if out of specification.
• Inspect thermostat (mechanical): On non‑electronic BlueStar ranges with mechanical thermostats, a stuck thermostat can cause overheating. If the oven continues heating after the knob is turned off, the thermostat must be replaced.
• Control board: If the sensor is good, the EOC relay may be stuck closed, continuously powering the burner or element. Replace the EOC.
• Verify wiring: If the issue began after a repair, double‑check all wiring against the schematic to ensure bake and broil circuits are correctly connected.
