An electric dryer can stop heating up after being used for years without any problems due to several possible reasons. Some common causes include:
Heating Element Failure: The heating element is responsible for generating the heat needed to dry the clothes. Over time, the heating element can wear out or develop defects, leading to a loss of heating capacity. If the heating element is faulty, it will need to be replaced.
Thermal Fuse or High-Limit Thermostat Failure: Electric dryers have safety components like thermal fuses and high-limit thermostats to prevent overheating. If the dryer overheats, these components will cut off power to the heating element. If they become defective or blown, the dryer won't produce heat.
Faulty Heating Element Assembly or Igniter: In some dryers, an assembly of components controls the heating element, including the igniter and gas valve coils. If any of these parts malfunction, the dryer won't heat properly.
Issues with the Power Supply: Problems with the electrical power supply to the dryer can lead to heating issues. It could be a tripped circuit breaker, a blown fuse, or improper voltage supply.
Blocked or Restricted Vent: A clogged or restricted dryer vent can cause the hot air to build up inside the dryer, triggering the thermal fuse to shut off the heating element. Regularly cleaning the dryer vent is crucial to maintaining proper airflow.
Control Board or Timer Malfunction: If the control board or timer that manages the dryer's heating cycles becomes faulty, it might prevent the heating element from turning on.
Wear and Tear: After years of use, various components in the dryer can wear down, leading to reduced efficiency or malfunctions.
If your electric dryer has stopped heating up, it's best to have a professional appliance repair technician inspect and diagnose the issue. They will be able to identify the specific problem and carry out the necessary repairs to get your dryer working efficiently again.
