The tumble dryer is a complementary household appliance to the washing machine, which works on an internal heating system. The air is sucked in from the outside by a turbine, it is then heated by the resistors of the dryer. The moist air turns into water which is finally stored in a collection tank. Like any other device, it is therefore necessary to ensure regular maintenance for the most fragile parts.

One of the parts that plays an important role in the efficiency and operation of the dryer is the door gasket. Indeed, it mainly seals the dryer and prevents hot air from leaking out of the appliance.

Through use, the door of your dryer may encounter problems, especially at the level of the seal. You may notice that:

  • your dryer is no longer airtight at the door,
  • the door no longer closes properly, in particular because of the deformation of the seal,
  • the porthole seal is totally damaged, there is either a hole or a crack,
  • the dryer does not heat up,
  • no program starts
  • the dryer does not spin.

As soon as you notice these signs, it must therefore be replaced. Since the operation is simple, you can do it by yourself.

The door seal of a clothes dryer is located at the entrance of the appliance, on which the door folds down when it is closed.

The door seal, also known as the door gasket, plays a crucial role in keeping the hot air inside the dryer during a drying cycle. Over time, the door seal may become worn, damaged, or lose its effectiveness, leading to leaks of hot air and reduced drying efficiency. If you notice any visible signs of wear or feel hot air escaping from the dryer door, it’s time to replace the door seal. In this step-by-step guide, we will walk you through the process of changing the door seal of a dryer.

How to Change the Door Seal of a Dryer: A Step-by-Step Guide

Step 1: Safety First

Before you start any repair work, ensure your dryer is disconnected from the power supply. Unplug the dryer from the electrical outlet or switch off the circuit breaker dedicated to the dryer.

Step 2: Access the Old Door Seal

To access the old door seal, you will need to open the dryer door fully. The door seal is secured around the dryer door’s inner perimeter. Carefully peel back the old door seal from the door, and you may need a flat-head screwdriver to gently pry it off if it’s stuck.

Step 3: Clean the Door Surface

With the old door seal removed, take the opportunity to clean the surface of the dryer door where the new door seal will be attached. Use a mild detergent and water or a suitable cleaning agent to remove any dirt, debris, or adhesive residue.

Step 4: Install the New Door Seal

Now it’s time to install the new door seal. Start by identifying the correct orientation of the seal; most door seals have a lip or channel that should face inward towards the dryer drum. Carefully press the door seal into place around the inner perimeter of the dryer door. Make sure the seal fits snugly and securely.

Step 5: Test the Seal

Once the new door seal is installed, close the dryer door and press along the seal to ensure it is properly seated and making full contact with the dryer door. This step is crucial to prevent any air leaks during the drying cycle.

Step 6: Reconnect Power and Test the Dryer

Before moving the dryer back into position, plug it back into the electrical outlet or switch on the circuit breaker. Perform a test run to check if the new door seal is functioning correctly. Turn on the dryer and run a short cycle to ensure there are no air leaks or issues with the new door seal.

Step 7: Final Adjustments

If you notice any air leaks or issues with the door seal during the test run, double-check the installation to ensure it is properly aligned and seated. Make any necessary adjustments to ensure a tight seal.
