Samsung Dryer Thermistor Test and Troubleshooting Tips

A faulty Samsung dryer thermistor can cause a range of issues, from inconsistent drying times to complete shutdowns.

The thermistor is a critical component that monitors the dryer's temperature, and a malfunctioning one can lead to reduced appliance performance.

One common symptom of a faulty thermistor is an error code, such as "NF" or "NE", which indicates a problem with the dryer's temperature sensing system.

To troubleshoot the issue, you'll need to locate the thermistor, which is usually situated near the dryer's heating element.

Testing the Dryer Temperature Sensor is a relatively straightforward process that can be done with a multimeter. You'll need to unplug the dryer from the power outlet first.

To access the temperature sensor, you'll need to remove the blower housing, which will give you access to the sensor itself. Be gentle when removing the wires connected to the old temperature sensor.

Set your multimeter to resistance mode and place the probes on the terminals of the temperature sensor. If the multimeter displays a reading within the manufacturer's specifications, then the temperature sensor is functioning correctly.

If the reading is outside the specifications, then it needs to be replaced. It's also worth noting that thermistors, which are often used in dryers, don't have continuity, so you'll need a multimeter that measures ohms to test them.

Here are the general steps to test a thermistor:

In general, a cool dryer at room temperature should measure 50,000 ohms. If the reading is lower than this level or no reading was detected at all, the thermistor is probably defective and should be replaced.

Testing a Samsung dryer thermistor can be a bit tricky, but with the right tools and knowledge, you can do it like a pro. The first step is to ensure you have a multimeter that measures ohms, since thermistors don't have continuity.

To test the thermistor, connect your multimeter to it with the power disconnected from the dryer. Then, use a hair dryer to blow hot air over the thermistor. As the thermistor becomes hotter, its resistance should decrease.

You can also use the ohm multimeter to take an initial reading of the thermistor's resistance. According to Manage My Life, a cool dryer (at room temperature) should measure around 50,000 ohms. If the reading is lower than this or no reading is detected, the thermistor might be defective.

To verify the accuracy of the thermistor, blow hot air over it with a hair dryer while the multimeter is still connected. The resistance should decrease as the thermistor becomes hotter. If you don't see a change in resistance, it's likely the thermistor needs to be replaced.

Here's a quick reference chart to help you understand the expected resistance values for your Samsung dryer thermistor:

Keep in mind that the specific resistance values for your dryer model can be found in the wiring diagram or technical guide.
