JennAir Oven: overheating
What is this symptom?
Experiencing overheating in your Jennair oven? This common issue can lead to food burning or cooking too quickly. If your oven runs significantly hotter than the set temperature, it may be caused by a faulty temperature sensor or other malfunctions. Understanding the causes and solutions can help restore your oven's performance.
Important Tips for JennAir Models
- Jennair ovens provide a temperature calibration feature to adjust internal temperature offset when running hotter than expected; specific calibration methods depend on model.
Possible Causes
Faulty or misaligned temperature sensor
How to Identify: Food burns at lower settings, external thermometer shows actual temp higher than set, sensor may appear bent or touching wall
Part: Oven temperature sensor
Stuck heating element or control board malfunction
How to Identify: Element remains glowing, oven continues to produce heat past set point, possible unusual display behavior/error codes
Part: Heating element / control board
DIY Solutions
Check and Replace Oven Temperature Sensor
- Disconnect power to oven.
- Locate the temperature sensor inside the oven cavity (usually a metal probe on rear wall).
- Visually inspect sensor for damage or contact with oven wall; reposition if touching.
- Test sensor resistance with a multimeter (refer to service manual specs).
- If faulty, replace with correct sensor for your model and secure wiring.
- Restore power and test oven temperature consistency.
Calibrate Oven Temperature Setting
- Refer to Jennair control calibration method (e.g., holding Temp/Time down arrow to access calibration).
- Adjust temperature offset downwards in small increments to match actual oven temp.
- Run test bake cycle to confirm temperature aligns with set value.
- Repeat adjustments if necessary within allowed range.
Improve Airflow and Remove Blockages
- Remove any foil or oversized liners blocking vents or interior space.
- Ensure racks are positioned to allow adequate air circulation around food.
- Clean visible vents of debris or food particles to improve airflow.
- Test oven performance after adjustments.

User Suggested Solutions
-
Check and replace the thermostat. First, unplug the oven. Remove the back panel to access the thermostat. Use a multimeter to test for continuity. If faulty, replace it with a new one.
-
Ensure proper ventilation. Confirm there is at least an inch of space between the speed oven and the lower oven. Adjust installation if necessary.
-
Inspect and replace the oven control board. Unplug the oven, remove the control panel, and check for burnt components. If damaged, replace the control board with a compatible part.
