Jenn-Air Oven Not Reaching Temperature — Causes And Solutions
Below, we have listed the possible reasons why your Jenn-Air oven won’t heat up to the set temperature and what to do about them.
If your Jenn-Air gas oven won’t heat up to the set temperature, it is most likely because the igniter has started to fail. The igniter is one of the oven’s main heating components. When the igniter starts to fail, it will light at the beginning of the cooking process but stop later on. To replace the igniter in your Jenn-Air oven, do the following…
Step 1: Unplug the oven’s power cord and shut off the gas supply for safety.
Step 2: Remove the lower cover on the rear of the oven. You will need to take out the screws which secure it using a Philips head screwdriver.
Step 3: Set the cover aside and disconnect the wire plug from the igniter.
Step 4: Open the oven door and take out the racks.
Step 5: Lift out the oven’s bottom panel and set it aside. If there are screws on the bottom panel, take them out first to lift it out.
Step 6: Take out the screws which hold the heat shield in place. Do this using a Philips head screwdriver.
Step 7: Remove the heat shield and take out the screws which hold the igniter to the burner tube. Take out the screws using a 5/16th inch nut driver.
Step 8: Get a new igniter.
Step 9: Position the new igniter on the burner tube and hold it in place with the screws.
Step 10: Pass the igniter’s wire plug through the hole in the oven’s rear.
Step 11: Return the heat shield and hold it in place with the screws.
Step 12: Reposition the bottom panel in the oven.
Step 13: If you took out any screws from the bottom panel, return them.
Step 14: Slide the racks back into the oven.
Step 15: Shut the door and go to the rear.
Step 16: Reconnect the igniter wire plug.
Step 17: Return the cover panel and the screws which secure it.
Step 18: Plug the oven’s power cord back in and turn on the gas supply.
The video below will show you how to replace the igniter in your Jenn-Air oven.
2. Bake Element
If your Jenn-Air electric oven doesn’t heat up to temperature, the bake element has started to fail. The bake element is the main heating component in a Jenn-Air electric oven. If the element starts to fail, it won’t heat up as much as it normally does. Read this article: Jenn-Air Oven Element [Issues & Proven Solutions] to replace the bake element in your Jenn-Air oven.
3. Temperature Sensor
If your igniter or bake element isn’t faulty, the temperature sensor may be. Below, we have listed the steps you need to follow in order to test and replace your Jenn-Air oven temperature sensor…
Step 1: Pull the oven away from the wall and go to the rear.
Step 2: Disconnect the oven’s power cord from the outlet to avoid the risk of electrocution.
Step 3: Get a Philips head screwdriver.
Step 4: Using the screwdriver, take out the screws which hold the oven’s rear access panel in place.
Step 5: Set the access panel aside.
Step 6: Disconnect the wire plug connected to the temperature sensor.
Step 7: Get a multimeter and turn the dial to the lowest ohms setting.
Step 8: Touch the two multimeter probes to the pins in the temperature sensor’s wire connector.
Step 9: Look at the reading on the multimeter’s display. The reading should be around 1080 to 1180 ohms at room temperature. If the reading is far off from this, the temperature sensor is faulty and should be replaced.
Step 10: Open the oven door slightly.
Step 11: Grip the sides of the oven door and lift it off the hinges.
Step 12: Set the door on a cloth lined surface.
Step 13: Slide out the racks in the oven.
Step 14: Take out the two Philips head screws which hold the temperature sensor in place. The sensor is on the oven’s upper back wall.
Step 15: Pull the sensor out of the oven.
Step 16: Get a new Jenn-Air oven temperature sensor.
Step 17: Insert the new temperature sensor into the oven and hold it in place using the two Philips head screws.
Step 18: Slide the racks back into the oven.
Step 19: Lift the oven door.
Step 20: Slide the door back onto the hinges.
Step 21: Open the door fully then shut it.
Step 22: Go to the oven’s rear and connect the wire plug to the new temperature sensor.
Step 23: Reposition the oven’s rear access cover.
Step 24: Hold the cover in place with the Philips head screws.
Step 25: Plug the oven’s power cord back into the outlet.
Step 26: Return the oven to its usual position.

Jenn-Air Oven Won’t Hold Temperature — How To Fix
If your Jenn-Air oven won’t maintain temperature, the bake element or igniter could be faulty. The igniter is the main heating component in a gas oven while the bake element is the main heating component in an electric oven. If they start to fail, the oven won’t maintain temperature. Read the section above to learn how to replace these components.
If the bake element or igniter isn’t faulty but your Jenn-Air oven won’t maintain temperature, you should test an maybe replace the sensor next. Read the section directly above to learn how to test and replace your Jenn-Air oven temperature sensor.
If these components aren’t faulty, the oven may be losing the temperature because the door isn’t properly closed. Check if the door is closed. If the door doesn’t close properly, the door hinges or door seal is faulty. Read this article: Jenn-Air Oven Door [How To, Issues & Proven Solutions] to learn how to replace the door hinges and door seal in your Jenn-Air oven.
How To Calibrate Jenn-Air Oven Temperature
Below, we have listed the steps you need to follow in order to calibrate your Jenn-Air oven temperature…
Step 1: To determine how much your oven needs to be calibrated by, first open the door and place a thermometer on the center rack.
Step 2: Shut the door and set the oven to bake at 350 degrees F.
Step 3: After about 20 minutes, take out the thermometer and look at the reading. If the reading is off by up to 10 degrees, it should be adjusted accordingly.
Step 4: Cancel the bake function.
Step 5: Press and hold down the “Temp/Time” down arrow for about 5 seconds. You should see something like “0F cal” or “00” when you do this. If that doesn’t work, hold down the “Bake” button for about 5 seconds.
Step 6: Using the arrows, enter how much you want to calibrate the oven’s temperature by.
Step 7: Press the “Start” button to save the changes.
If the method above for calibration doesn’t work on your Jenn-Air oven model, do the following…
Step 1: Tap the “settings” button.
Step 2: Scroll through the available functions and select “Temperature calibration” or “Oven Calibration.
Step 3: Select how much you want to add or deduct from the oven’s current temperature.
Step 4: To save your selection, press the “Start” button. To exit calibration mode without changes, simply press the “Cancel” button.
