Possible Causes

Actual over-temperature condition on glass top, Defective surface temperature sensor reading too high, Poor airflow around range causing heat buildup, Failed main PCB interpreting sensor data incorrectly

How to Fix / Troubleshooting

Safety first: Turn OFF all burners and the oven. Unplug the range or switch OFF the breaker if any burning smell or smoke is present.

Cooling and reset:

  • Remove all cookware from the cooktop.
  • Allow the cooktop to cool for at least 45–60 minutes.
  • Restore power and test one burner at a low setting to see if the error reappears.

Usage checks:

  • Avoid using oversized pans that cover multiple burners.
  • Ensure the oven vent is not blocked by foil, pans, or covers.
  • Verify that the range has proper clearance from cabinets as specified in the installation manual.

If error persists:

  • Disconnect power and inspect the surface temperature sensor and wiring for damage or loose connections.
  • If the sensor is deformed, discolored, or tests out of spec with a multimeter, replace it.

Professional service: If the sensor and wiring are good but C-22 continues, the main PCB may be misreading the sensor and should be evaluated by a technician.
