  • Blocked oven vents preventing proper airflow and cooling.
• Troubleshooting Steps:
  1. Allow the Oven to Cool: Turn off the oven and let it cool down completely for a few hours.
  2. Check for Blocked Vents: Ensure the oven vents (usually located at the back of the cooktop) are not blocked by cookware or debris.
  3. Power Cycle: Disconnect power to the range for at least 30 seconds and then reconnect.
  4. Professional Service: If the error persists after cooling and checking vents, the issue could be a faulty oven sensor, a stuck heating element relay on the main PCB, or a defective main PCB. These require diagnosis and repair by a qualified technician. Measuring heater element resistance (e.g., Bake heater 22−25Ω, Broil heater 15−17Ω) and voltage supply should only be performed by a professional.

C-23: Meat Probe Shorted Error

This code indicates a problem with the meat probe or its circuit.

• Possible Causes:
  • A shorted meat probe.
  • A damaged wiring harness for the meat probe.
  • A defective main PCB.
