Understanding the Problem
When your oven is set to 350 degrees but food consistently comes out undercooked or burnt, the oven is not holding the correct temperature. This is usually caused by a faulty oven temperature sensor (also called an RTD sensor), a malfunctioning thermostat, or a failing control board. The temperature sensor is a thin metal probe inside the oven that reads the temperature and sends the information to the control board. If the sensor gives a wrong reading, the oven will heat to the wrong temperature.
Common Causes
- Faulty oven temperature sensor (RTD sensor)
- Malfunctioning thermostat
- Failing oven control board
- Damaged or loose sensor wiring
- Worn door gasket allowing heat to escape

Helpful Repair Tip
You can test the oven temperature sensor with a multimeter. At room temperature, it should read approximately 1,080 to 1,100 ohms of resistance. If the reading is significantly off, the sensor needs to be replaced. You can also use an oven thermometer placed inside the oven to compare the actual temperature to the set temperature — a difference of more than 25 degrees usually means the sensor or thermostat is faulty. Some ovens also allow you to calibrate the temperature offset in the settings menu.
Brand-Specific Issues
Common problems reported by brand
GE
"GE oven F7 error"The F7 error code on GE ovens indicates a stuck or shorted key on the control panel, but it's most commonly caused by a faulty electronic oven control (EOC) board or a failing temperature sensor (also called an RTD probe). If your GE oven displays F7 or has inaccurate temperature, try replacing the temperature sensor first—it's much cheaper than the control board.
