How to check thermistor on dryer. A thermistor is a component in a dryer that helps to regulate the temperature inside the appliance.
If the thermistor is not functioning properly, it can lead to issues with your dryer’s performance and potentially even damage to the appliance.
In this article, we’ll explore the steps involved in checking a thermistor on a dryer.
How to check thermistor on dryer
Here is step by step guide to check thermistor on dryer:
Step 1: Gather your tools and materials
Before you begin, you’ll need to gather the following tools and materials:
- Screwdriver
- Multimeter
Step 2: Disconnect the power to the dryer
To ensure your safety, it’s important to disconnect the power to the dryer before you begin any repairs. Unplug the dryer or flip the circuit breaker that controls the outlet.
Step 3: Locate the thermistor
The thermistor is typically located inside the dryer drum or near the heating element. Refer to your dryer’s user manual or consult a professional if you’re having trouble finding it.
Step 4: Test the thermistor with a multimeter
Use a multimeter to test the thermistor to determine if it’s functioning properly. Set the multimeter to the resistance setting and touch the probes to the thermistor’s terminals.
The multimeter should read a resistance value if the thermistor is functioning correctly. If the reading is infinite or very low, it could be a sign that the thermistor is not functioning correctly.
Step 5: Check the continuity of the thermistor
Set the multimeter to the continuity setting and touch the probes to the thermistor’s terminals. The multimeter should beep if the thermistor is functioning correctly. If the multimeter does not beep, it could be a sign that the thermistor is not functioning correctly.
Step 6: Check the resistance of the thermistor at different temperatures
To ensure that the thermistor is functioning properly over a range of temperatures, it’s a good idea to check the resistance of the thermistor at different temperatures.
To do this, you’ll need to heat up the thermistor with a heat gun or by placing it in a pot of boiling water. Take readings of the resistance at different temperatures and compare them to the manufacturer’s specifications to ensure that the thermistor is functioning within the expected range.
Why do I need to check my dryer’s thermistor?
There are several reasons why you might need to check your dryer’s thermistor. The most common reason is if the thermistor is not functioning properly, which can lead to issues with your dryer’s performance and potentially even damage to the appliance.
