Dryer not heating? don’t panic! here’s why and how to fix it
What To Know
- If the control board malfunctions, it may not send the correct signals to the heating element, resulting in a lack of heat.
- If the moisture sensor malfunctions, it may not detect the moisture correctly, leading to insufficient drying and a lack of heat.
- Whether you need to replace a faulty heating element or clean a clogged exhaust vent, understanding the underlying causes will empower you to restore heat to your dryer and keep your clothes dry and warm.
If your Whirlpool dryer has suddenly stopped heating up, leaving your clothes damp and cold, it can be a frustrating experience. Understanding the reasons behind this issue can help you troubleshoot the problem effectively. Here are the most common causes of a Whirlpool dryer not getting hot:
1. Faulty Heating Element
The heating element is the central component responsible for generating heat in the dryer. Over time, it can wear out or develop a fault, leading to a lack of heat. To check if the heating element is faulty, use a multimeter to test its continuity. If it reads infinite resistance, it needs to be replaced.
2. Thermal Fuse Blown
The thermal fuse is a safety device that protects the dryer from overheating. If the dryer temperature rises above a safe level, the fuse will blow, cutting off power to the heating element. To check the thermal fuse, look for a small, cylindrical component near the heating element. If it is blown, it will need to be replaced.
3. Faulty Thermostat
The thermostat regulates the temperature inside the dryer. If it malfunctions, it may not send the correct signal to the heating element, resulting in insufficient heat. To test the thermostat, use a multimeter to check its resistance. If it is not within the specified range, it needs to be replaced.
4. Clogged Exhaust Vent
A clogged exhaust vent can restrict airflow and prevent the dryer from heating up properly. Lint and debris can accumulate over time, blocking the vent. To clean the exhaust vent, disconnect the dryer and remove any visible lint. You can also use a vacuum cleaner or a vent cleaning brush to thoroughly unclog the vent.
5. Faulty Control Board
The control board is the brain of the dryer, controlling various functions, including the heating element. If the control board malfunctions, it may not send the correct signals to the heating element, resulting in a lack of heat. To test the control board, you will need to use a multimeter to check its voltage and continuity.
6. Broken Drive Belt
The drive belt connects the motor to the dryer drum. If the belt breaks or becomes loose, it can prevent the drum from rotating properly, which in turn affects the heating process. To check the drive belt, open the dryer door and inspect the belt for any signs of damage or wear. If it is broken or loose, it will need to be replaced.
7. Moisture Sensor Malfunction
Some Whirlpool dryers have a moisture sensor that detects the moisture level of the clothes and adjusts the drying cycle accordingly. If the moisture sensor malfunctions, it may not detect the moisture correctly, leading to insufficient drying and a lack of heat. To test the moisture sensor, use a multimeter to check its resistance.
Resolving the Issue
Once you have identified the cause of the problem, you can proceed with the necessary repairs or replacements. If you are not comfortable working on electrical appliances, it is recommended to contact a qualified appliance repair technician.
Troubleshooting Tips
- Before troubleshooting, ensure that the dryer is properly plugged into a working outlet.
- Check if the dryer is set to the correct drying cycle. Some cycles may not use heat.
- Clean the lint filter regularly to prevent lint buildup from clogging the exhaust vent.
- Inspect the dryer drum for any tears or holes that may allow heat to escape.
Final Note: Restoring Heat to Your Whirlpool Dryer
By following these troubleshooting steps, you can diagnose and resolve the issue of your Whirlpool dryer not getting hot. Whether you need to replace a faulty heating element or clean a clogged exhaust vent, understanding the underlying causes will empower you to restore heat to your dryer and keep your clothes dry and warm.
