3. Method 1: Using The Continuity Setting On A Multimeter
One of the most common and accurate methods to test a dryer heating element is by using a multimeter. A multimeter is a handy device that measures electrical characteristics such as voltage, current, and resistance. To test the heating element using the continuity setting on a multimeter, follow these steps:
-
Set the multimeter to the continuity or “diode” setting. This setting allows the multimeter to send a small electrical current through the heating element and measure if there is a complete circuit or continuity.
-
Disconnect the heating element from the dryer, carefully removing any wire connections or fasteners that hold it in place.
-
Place one of the multimeter probes on one end of the heating element’s terminal and the other probe on the opposite end. The multimeter should emit a beeping sound or display very low resistance if the heating element is functioning properly.
-
Repeat this process for each terminal of the heating element to ensure all the coils are intact. If there is no continuity or beeping sound when testing any of the terminals, it indicates a faulty heating element that needs to be replaced.

- Place one probe on each end of the heating element’s terminal
- Check for a beeping sound or low resistance
- Repeat for each terminal
“If there is no continuity or beeping sound when testing any of the terminals, it indicates a faulty heating element that needs to be replaced.”
4. Method 2: Using The Lowest Ohm Setting On A Multimeter
Another method to test a dryer heating element is by using the lowest ohm setting on a multimeter. Ohms measure the resistance of electrical components. To use this method, follow these steps:
- Disconnect the heating element from the dryer, as mentioned earlier in step 2 of the previous section.
- Set the multimeter to the lowest ohm setting available.
- Connect one probe of the multimeter to one of the heating element’s terminals.
- Touch the other probe to the second terminal. The multimeter should display a specific resistance value, typically within a certain range specific to your dryer model.
- Repeat this process for each terminal, and compare the resistance values obtained to the specifications provided by the manufacturer. If the resistance values significantly deviate from the manufacturer’s specifications, it indicates a faulty heating element that needs to be replaced.
Please note that specific instructions for this method may vary depending on the brand and model of your multimeter. It is important to consult the user manual or online resources specific to your multimeter for accurate usage instructions.
