If your Whirlpool dryer has stopped heating up, don’t panic! This common issue can often be resolved with some basic troubleshooting and repair techniques. In this comprehensive guide, we will explore the potential causes behind a non-heating Whirlpool dryer and provide step-by-step instructions on how to fix it.
Potential Causes and Troubleshooting
1. Power Supply:
- Check if the dryer is properly plugged into a working outlet.
- Reset the circuit breaker or fuse associated with the dryer.
2. Thermal Fuse:
- A blown thermal fuse can prevent the dryer from heating up.
- Locate the thermal fuse (usually near the heating element) and replace it if necessary.
3. Heating Element:
- A faulty heating element is another common cause of a non-heating dryer.
- Test the heating element with a multimeter; a reading of infinity indicates a broken element.
- Replace the heating element if it’s malfunctioning.
4. Thermostat:
- The thermostat regulates the temperature of the dryer.
- Use a multimeter to check for continuity; a lack of continuity indicates a faulty thermostat.
