If an electric dryer stops producing heat but continues to tumble and make noise, it could be due to one of the following reasons:
Heating element failure: Electric dryers utilize a heating element to generate heat. Over time, the heating element may wear out or become damaged, resulting in a lack of heat production. If the heating element is faulty, the dryer will continue to run but won't provide the necessary heat to dry the clothes.
Thermal fuse tripped: Dryers have a thermal fuse as a safety feature to prevent overheating. If the temperature inside the dryer reaches an unsafe level, the thermal fuse will trip and interrupt the heating circuit. In this case, the dryer will still run, but the heating element won't receive power. A tripped thermal fuse often indicates an underlying issue, such as blocked vents or a malfunctioning thermostat, that caused the temperature to rise.
Faulty thermostat: Dryers have multiple thermostats that monitor and regulate the temperature. If a thermostat malfunctions, it can prevent the heating element from receiving power, resulting in no heat production. A faulty thermostat may require replacement to restore proper heating functionality.
Electrical issue: There may be an electrical problem within the dryer's electrical system, such as a faulty wiring connection or a defective control board. These issues can disrupt the flow of power to the heating element, causing it to stop producing heat while the motor continues to run.
To address the issue, you can take the following steps:
Check the lint filter and vents: Ensure that the lint filter is clean and the dryer vents are clear of lint or debris. Clogged vents can restrict airflow, leading to overheating and tripping of safety features like thermal fuses.
Reset the thermal fuse: If you suspect the thermal fuse has tripped, locate and reset it according to your dryer's user manual. However, it's important to note that a tripped thermal fuse may be an indication of an underlying issue, so further investigation is recommended.
Test the heating element and thermostats: Using a multimeter, you can test the continuity of the heating element and thermostats to determine if they are functioning properly. If any of these components show no continuity, they may need to be replaced.
Seek professional assistance: If you are unsure or uncomfortable with diagnosing or repairing electrical components, it is advisable to contact a qualified appliance repair technician. They have the expertise to safely diagnose and fix issues with electric dryers.
Remember, when dealing with electrical appliances, it's crucial to prioritize safety. Always disconnect the dryer from the power source before conducting any inspections or repairs and consult the manufacturer's guidelines or seek professional help if needed.
