Likely Causes
  1. Oven temperature sensor has an internal short, reading near zero resistance
  2. Sensor wiring insulation has melted and the wires are touching each other
  3. Moisture has entered the sensor connector causing a low-resistance path
  4. Incorrect sensor with wrong resistance characteristics was installed
How to Fix It
1
Disconnect power and measure the sensor resistance (should be approximately 1080 ohms at room temp; a reading near 0 confirms a short)
2
Inspect the sensor wiring for melted insulation or bare wires touching
3
Check the connector for moisture or debris that could cause a false short
4
Replace the temperature sensor if the resistance is near zero ohms
Pro Tip
This is a common issue that most users can resolve without specialized tools. Try the first step before moving on to more complex solutions.
