How to Change the Temperature Sensor of a Dryer

The tumble dryer is a complementary household appliance to the washing machine, which works on an internal heating system. The air is sucked in from the outside by a turbine, it is then heated by the resistors of the dryer. The moist air turns into water which is finally stored in a collection tank. Like any other device, it is important to ensure that all its parts are always in good condition.

The temperature sensor is an essential part for the proper functioning of your dryer since it regulates the temperature of the dryer. This probe is linked to the drying module: it informs it of the temperature which is detected then transmits the information to the thermostat via the electronic card. It is thanks to the probe that the thermostat will have the information that the right temperature has been reached and that it must stop heating the appliance.

With time and use, the probe may no longer perform its function correctly. Here are the signs that prove that the probe is no longer working:

  • the dryer does not heat up,
  • the resistors do not work,
  • no drying program starts,
  • the dryer is heating too much or not enough.

If the problem is at this level, it must be replaced. It is a simple operation that you can do by yourself.

A clothes dryer’s probe is located inside under the drum. To access it, you must remove the rear panel and then the drum.

The temperature sensor in a dryer, also known as the thermistor, is a crucial component responsible for monitoring the temperature inside the drum. It provides valuable feedback to the dryer’s control board, allowing it to regulate the heating element and ensure optimal drying performance. If you notice issues with your dryer not heating correctly or displaying error codes related to temperature, the temperature sensor may be faulty and require replacement. Changing the temperature sensor may seem challenging, but with the right tools and guidance, you can successfully replace it. In this step-by-step guide, we will walk you through the process of changing the temperature sensor of a dryer.

How to Change the Temperature Sensor of a Dryer

Step 1: Safety Precautions

Before starting any repair work on your dryer, prioritize safety. Ensure the dryer is disconnected from the power supply by unplugging it from the electrical outlet or switching off the circuit breaker dedicated to the dryer.

Step 2: Access the Temperature Sensor

To access the temperature sensor, you will need to open the dryer’s cabinet. The specific steps to access the sensor may vary depending on your dryer model. Generally, you will need to:

  1. Remove any screws or clips securing the dryer’s top panel to the cabinet. Slide a putty knife or a similar tool between the top and front panels to release any hidden clips.
  2. Lift the top panel and prop it up securely.
  3. Locate and remove the screws or clips securing the front panel to the sides of the cabinet.
  4. Carefully tilt the front panel forward and disconnect any wires or cables attached to the door switch.
  5. Set the front panel aside.

Step 3: Locate the Temperature Sensor

With the front panel removed, locate the temperature sensor. It is usually a small cylindrical component attached to the dryer’s blower housing or near the heating element assembly.

Step 4: Disconnect Wiring

Before removing the temperature sensor, carefully disconnect the wiring harness connected to it. Take note of the location and arrangement of the wires to ensure you can reconnect them correctly later.

Step 5: Remove the Old Temperature Sensor

Gently remove the old temperature sensor from its position. It may be secured with screws or clips. Unscrew or unclip the sensor to release it from the dryer.

Step 6: Install the New Temperature Sensor

Position the new temperature sensor in place, aligning it with the corresponding holes or slots. Secure it in place using the appropriate screws or clips.

Step 7: Reconnect Wiring

Carefully reconnect the wiring harness to the new temperature sensor. Make sure each wire is attached to the correct terminal based on the notes you took during disconnection.

Step 8: Reassemble the Dryer

With the new temperature sensor installed and the wiring reconnected, it’s time to reassemble the dryer. Reverse the steps you followed to access the sensor and secure the front panel back onto the dryer’s cabinet.

Step 9: Test the Dryer

Before pushing the dryer back into its designated spot, perform a test run to check if the new temperature sensor is functioning correctly. Turn on the dryer and run a drying cycle to ensure proper temperature regulation.

Step 10: Final Adjustments

If you encounter any issues with the new temperature sensor during the test run, double-check the installation and wiring connections. Make any necessary adjustments to ensure accurate temperature monitoring and control.


Changing the temperature sensor of a dryer is a manageable task with the right guidance. By following this step-by-step guide, you can successfully replace this critical component and restore optimal heating and drying performance to your dryer. Properly functioning temperature sensor ensures that the dryer operates at the correct temperature, providing efficient and effective drying results. However, if you encounter any difficulties during the process or have concerns about handling the repair, it’s always best to seek assistance from a professional dryer technician. With the new temperature sensor in place, you can enjoy reliable drying performance and the peace of mind that your dryer is operating at its best.
