GE Oven Overheating? Here’s Why (+ How to Fix)

A GE oven is already hot during normal cooking cycles. As such, problems that increase oven temperatures beyond normal levels can cause malfunctions or even accidents. Therefore, it’s important to prevent issues that cause your GE oven to overheat.

These 3 issues are the most common causes of GE oven overheating: 

  • A faulty oven temperature sensor.
  • A defective temperature thermostat.
  • A blocked oven vent.

This article breaks down the problems that cause your GE oven to overheat. It also provides simple guidelines on how to resolve the issues. Keep reading! 

A Faulty Oven Temperature Sensor

A GE oven temperature sensor communicates with the oven control board to regulate the amount of heat in the oven. When the temperature in the oven rises, the sensor increases its resistance and causes the oven to cycle to maintain the required temperatures. 

When the temperature in the oven drops, the sensor decreases its resistance so the oven can start heating. 

If the temperature sensor is faulty, it won’t detect rising oven temperature and won’t increase resistance to make the oven cycle. This means the heating elements may stay on all the time, causing the oven to overheat.

How To Fix a Faulty GE Oven Temperature Sensor

First, isolate and test the temperature sensor for continuity before replacing it (if that’s necessary). Then, follow these steps:

  1. Cut the power supply to the oven.
  2. Remove the oven’s rear panel and disconnect the sensor wire.
  3. Remove oven racks to clear your way to the sensor. You may also want to remove the oven door by lifting it. Removing the door will make it easier to access the sensor.
  4. Locate the sensor screws at the rear of the oven and unscrew them to release the sensor. The sensor looks like a metal rod.
  5. Pull out the sensor through the hole in the oven wall.
  6. Test the sensor for resistance using a multimeter. The sensor should record a value of around 1100 ohms if it’s working normally. A value that deviates too far from this indicates a faulty temperature sensor that needs to be replaced.
  7. To replace the sensor, pass it through the hole in the oven wall and screw it in place. Reconnect the wires at the oven’s rear and replace the oven rear panel. Fix the oven door back if you removed it.

A Defective Temperature Thermostat

The temperature thermostat controls heat in the oven by regulating the oven’s heat cycles. If the thermostat is defective, the temperature will keep going up when the oven should cycle off, leading to overheating. 

How To Fix a Defective GE Oven Thermostat

You’ll need to replace a defective GE oven thermostat. Here’s how to do that:

  1. Disconnect the oven from the power supply.
  2. Pull out the thermostat knob from the oven. If it feels hard to pull out, use a string to help get it out. 
  3. Remove the rear panel of the range by taking away the screws.
  4. Disconnect the thermostat wires.
  5. Take out the screws holding the thermostat assembly. These screws are next to where you removed the thermostat knob. 
  6. Remove the old thermostat. 
  7. Place the new thermostat in the place of the old one and screw it onto the panel.
  8. Reattach the connection wires.
  9. Remove the sensing bulb route from the old thermostat and connect it to the new one.
  10. Screw back the panel and fit back the thermostat knob.

A Blocked Oven Vent

GE ovens have a vent that dispels steam and hot air when the oven is running. This vent has a duct under the rear surface of the right side of the range. The vent and duct can get blocked due to grease buildup or if objects are placed on top of the vent trim. If this happens, hot air is not vented, causing the oven to overheat.

How To Fix a Blocked GE Oven Vent

The GE oven manufacturer recommends that you regularly clean your oven vent area to prevent blockage. To clean your GE oven vent: 

  1. Ensure the oven is not running and not hot from a just-completed cooking cycle.
  2. Use water and soap and a non-abrasive pad to remove dirt and grease on the vent trim. You can also use a stainless-steel degreaser. A highly effective product in grease removal and one that leaves the oven with a luminous finish like the Weiman Cooktop/Stove Top Cleaner (available on Amazon.com) is recommended. It’s safe and easy to use and works for a wide range of delicate surfaces.
  3. Use a soft cloth to dry the vent trim.

Other less common causes of GE oven overheating include:

  • A shorted-out heating element (broil or bake).
  • A defective fan motor.
  • A malfunctioning oven control board.
  • A loose control knob that doesn’t show the exact temperature.

Remember to always contact a professional GE oven technician for issues you’re not sure you can fix safely and successfully.
