  • If the sensor is dirty, gently clean it with a soft cloth to remove any dust or debris.

6. Test the Sensor

  • If you have a multimeter, test the sensor’s resistance and compare the readings with the specifications provided in the user manual.

7. Reconnect or Replace the Sensor

8. Inspect the Control Board

  • Check the control board for any visible signs of damage, such as burnt components or loose connections. If there are issues, the control board may need to be repaired or replaced.
