One possible cause of a Kenmore 70 series dryer not heating is an obstructed exhaust duct. If the exhaust is clogged or obstructed at any point from inside the dryer to where it exits the building, the dryer may overheat and pop the thermal fuse. It is important to check and clean the dryer vent regularly to prevent fire hazards.

Start by checking the thermal fuse and cleaning the lint filter or screen, which is often the first component to get clogged. A clogged vent not only restricts airflow but can also cause lint buildup, increasing the risk of a fire. Regular dryer vent cleaning helps maintain proper airflow and prevents potential issues with the thermal fuse.

Refer to the image below for a visual representation of a clogged dryer vent:

  1. Inspect the exhaust duct and vent hood outside the building for any obstructions, such as debris, bird nests, or accumulated lint.
  2. Remove any visible blockages carefully, ensuring not to damage the vent or duct.
  3. Use a vacuum cleaner or a flexible brush to clean the inside of the vent duct, removing any built-up lint or debris.
  4. Make sure the vent flaps on the vent hood open and close freely.
  5. Reattach the exhaust duct securely to the dryer and the vent hood outside.
  6. Run the dryer with the vent hose disconnected and check for proper airflow. If the airflow is strong, the vent duct is clear.

Regularly performing these maintenance steps to clear the clogged vent and ensure proper dryer vent cleaning can help prevent issues with the thermal fuse and maintain the efficiency and safety of your Kenmore 70 series dryer.

Faulty Heating Element
