Understanding The Moisture Sensor On Dryer
Importance Of The Moisture Sensor In Dryer Performance
The moisture sensor is a crucial component of your dryer that detects the moisture levels in your clothes during the drying cycle. It plays a vital role in ensuring efficient and effective drying. Understanding how the moisture sensor functions and how to test it can help you troubleshoot any issues and ensure that your dryer operates optimally.
How Does The Moisture Sensor Work?
Before we delve into testing the moisture sensor on your dryer, let’s explore how it operates. The moisture sensor uses electrical conductivity to measure the moisture content in your clothes. It contains two metal strips or rods that are in contact with the clothes as they tumble.
When your clothes are wet, they conduct electricity better, resulting in a stronger electrical signal. As the clothes start to dry, the electrical signal diminishes. The moisture sensor detects this decrease in electrical conductivity and signals the dryer to continue drying if the clothes are still damp or to stop the drying process if they are sufficiently dry. This feature prevents over-drying and saves energy.
Testing The Moisture Sensor Using A Multimeter
If you suspect that the moisture sensor on your dryer is not functioning properly, you can verify its performance using a multimeter. Here’s a step-by-step guide to help you through the process:
- Gather the necessary tools: You will need a multimeter, a small screwdriver, and the user manual for your dryer.
- Safety first: Before starting any electrical testing, ensure that the dryer is unplugged or turned off from the power source to avoid electric shock.
- Locate the moisture sensor: Refer to your dryer’s user manual to identify the location of the moisture sensor. It is typically found near the lint filter or on the front bulkhead.
- Access the moisture sensor: Use the small screwdriver to remove any screws or fasteners that secure the sensor in place. Carefully detach the sensor from its housing to gain access to the wiring.
- Set up the multimeter: Turn on the multimeter and select the “ohms” function, which measures electrical resistance.
- Test the moisture sensor: Place the multimeter probes on the metal contacts of the sensor. If the sensor is functioning correctly, the multimeter should display a resistance reading within the specified range mentioned in your dryer’s user manual. Any significant deviation from the expected range indicates a faulty moisture sensor that needs to be replaced.
- Replace or reassemble the sensor: If the moisture sensor fails the resistance test, you may need to replace it. Refer to your dryer’s user manual for specific instructions on replacing the sensor. If the sensor passes the test, carefully reassemble it and secure it back in place.
Testing the moisture sensor on your dryer with a multimeter is a straightforward process that allows you to diagnose any potential issues accurately. By understanding the importance of the moisture sensor and implementing regular testing, you can maintain the optimal performance of your dryer and ensure clothes are dried efficiently every time.

Steps To Test The Moisture Sensor On Dryer Using A Multimeter
Testing the moisture sensor on your dryer is an important step in troubleshooting any issues related to drying performance. Using a multimeter, you can easily check the functionality of the moisture sensor and ensure that it is accurately detecting the moisture levels in your laundry. Follow these steps to test the moisture sensor on your dryer using a multimeter:
Step 1: Disconnect The Dryer From The Power Source
Before you start testing the moisture sensor, it is crucial to disconnect the dryer from the power source. This will ensure your safety during the testing process and avoid any potential electrical hazards. Unplug the dryer from the electrical outlet or turn off the circuit breaker that supplies power to the dryer.
Step 2: Locate The Moisture Sensor In The Dryer
The next step is to locate the moisture sensor in your dryer. Different dryers may have the moisture sensor located in different positions, but typically it is located near the lint filter or inside the drum. Consult your dryer’s user manual to find the exact location of the moisture sensor if you are unsure.
Step 3: Access The Moisture Sensor Wiring Harness
Once you have located the moisture sensor, you need to access the wiring harness connected to it. The wiring harness may be secured with clips or screws, so use the appropriate tools to remove any obstacles that are blocking your access to the wiring harness.
Step 4: Prepare The Multimeter For Testing
Before proceeding with the testing, you need to prepare your multimeter. Set the multimeter to the continuity test mode or the resistance mode, depending on the specifications of your multimeter. Refer to the multimeter’s user manual for instructions on selecting the desired mode.
Step 5: Test For Continuity In The Moisture Sensor
The next step is to test for continuity in the moisture sensor. Using the multimeter probes, touch the two terminals of the moisture sensor. If the multimeter shows a reading of zero or very low resistance, it means that there is continuity and the moisture sensor is functioning correctly. If the multimeter shows no continuity or very high resistance, it indicates a faulty moisture sensor that needs to be replaced.
Step 6: Test For Proper Resistance Values With The Multimeter
In addition to testing for continuity, you should also test the moisture sensor for proper resistance values. Consult your dryer’s user manual to find the specifications and resistance values for the moisture sensor. Touch the multimeter probes to the corresponding terminals of the moisture sensor and compare the readings with the specified values. If the readings deviate significantly from the specified values, it may indicate a faulty sensor that needs to be replaced.
Step 7: Interpret The Test Results And Troubleshoot Any Issues
After completing the tests, interpret the results based on the readings you obtained. If the moisture sensor passes both the continuity and resistance tests, it means that the sensor is functioning correctly. However, if the sensor fails either of the tests, it indicates a problem with the sensor that requires further investigation. Refer to your dryer’s user manual for troubleshooting steps, or consult a professional technician to resolve the issue.
Troubleshooting Common Problems With The Moisture Sensor
