Error Codes (F11): Troubleshooting, Fixes & Prevention Tips explained below.

Explanation of High Temperature Error in Convection Mode❓

The "High Temp in Convection Mode" error indicates that the appliance’s internal temperature has exceeded safe or expected limits while running in convection mode. Convection ovens use a fan and additional heating element to circulate hot air, providing even cooking. If the system senses a temperature higher than the safe threshold, it triggers this error to protect internal components from overheating and to maintain user safety. This issue can cause the oven to shut down mid-cycle, refuse to preheat properly, or lock out further use until it cools down. The error may be caused by a faulty thermostat, a stuck relay, airflow obstruction, or a malfunctioning temperature sensor that misreads conditions inside the cavity.

ovens-microwaves - Likely Causes of Excessive Heat During Convection

  • Faulty or inaccurate oven temperature sensor (thermistor).
  • Stuck relay causing continuous power to the heating element.
  • Defective control board mismanaging heat cycles.
  • Non-functioning or blocked convection fan.
  • Heavy buildup of grease, residue, or foil inside oven cavity.
  • Improper user settings (e.g. high temp + long cycle).

ovens-microwaves - Steps to Resolve Convection Overheating❓

  • Unplug and Let the Oven Cool

    1. Turn off the appliance and disconnect it from the power source.
    2. Wait at least 30–60 minutes to allow all internal parts to cool.

  • Check Oven Fan Operation

    1. Ensure the convection fan runs during cooking—if it fails, heat may concentrate in one area.
    2. Replace the fan motor if it does not operate.

  • Inspect Temperature Sensor

    1. Locate the oven sensor and use a multimeter to test resistance.
    2. If it reads outside the expected range, replace the sensor.

  • Look for Relay Stuck Closed

    1. A stuck heating element relay can cause continued heating even when not needed.
    2. A technician can test and replace the control board or relay if faulty.

  • Clear Obstructions

    1. Ensure vents and fan inlets aren’t blocked by foil, cookware, or food debris.
    2. Obstructed airflow leads to heat buildup.

  • Reset the Oven

    1. After cooling and inspection, plug the oven back in and try using a lower-temperature mode first.
    2. Monitor to see if the error returns.

ovens-microwaves - Preventive Tips for Avoiding Convection Overheating

  • Always allow airflow—don’t cover vents or fans with foil or cookware.
  • Preheat the oven only to the required temperature—avoid running at max heat unnecessarily.
  • Clean the fan and oven cavity regularly to prevent buildup of grease or obstructions.
  • Avoid running convection mode back-to-back without allowing cool-down.
  • If roasting for long periods, check the manual’s recommended temp limits.
  • Inspect your oven annually for sensor and fan performance.

FAQs – High Temperature in Convection Mode❓

Question: Is the high temp error dangerous
Answer: Yes, it is a safety-triggered alert to prevent overheating and protect internal components or nearby surfaces.
Question: Will cooling down fix the issue
Answer: Cooling may reset the error temporarily, but the root cause (sensor, relay, fan) must be fixed to prevent recurrence.
Question: Can poor airflow cause overheating
Answer: Yes. Blocked vents or a broken convection fan can cause heat to build up and trigger the error.
Question: Should I replace the control board
Answer: Only if diagnosed properly. A technician can determine if the relay or control board is responsible.
Question: How often should I inspect the oven sensor
Answer: For heavy usage, a yearly check is recommended to catch faults early before they trigger errors.

When to Contact a Technician

If you experience any of the following issues even after completing the recommended troubleshooting steps, please contact an authorized service technician or our support team for further assistance.
