Oven cycles on and off very frequently, causing noticeable temperature swings.

Safety first: Turn off power before accessing the sensor or control.

Steps:

• Verify with thermometer: Use an oven thermometer to confirm that average temperature is close to the setpoint despite cycling.
• Sensor check: Inspect the sensor mounting to ensure it is secure and not touching the oven wall directly. Replace the sensor if readings are erratic.
• Load considerations: Avoid opening the door frequently, which can exaggerate perceived cycling.
