Gasket Maintenance

Before you jump straight into replacing the gasket, it’s important to do the following to maintain it so it lasts longer. 

  • Step 1. Inspect the gasket - Check the gasket for any tears or damages. If the gasket just appears dirty, then it needs to be cleaned. If it’s damaged, you need to replace it. 
  • Step 2. Clean the gasket - Wipe down the gasket with a cloth that is dampened with hot water and dish soap.
  • Step 3. Rinse and dry the gasket - Use separate, clean cloths to rinse the dry off the gasket. 

Gasket Replacement

  • Step 1. Remove the old gasket - Pull the dart of the old gasket out of the retainer slot and gently peel off the entire gasket. 
  • Step 2. Check the retainer - Inspect the retainer slot to ensure none of the old gasket or debris is present. Clean anything out of the slot as needed.
  • Step 3. Install new gasket at the first corner - Insert the dart into the retainer slot of one of the corners and attach 2 inches of the gasket in each direction of the corner.
    • Note: A mallet with masking tape on it can be used as needed to help secure the gasket. 
  • Step 4. Install at the remaining corners - Repeat step 3 on the remaining corners of the door.
  • Step 5. Finish installing the gasket - Continue to insert the dart into the retainer slot and work from the center of each side and move outwards toward the corners.
  • Step 6. Inspect the gasket - Check that the dart is secure by lifting the gasket base on the outer edge.
