• Screwdriver – A Philips head screwdriver to remove any screws.
• Putty Knife – To pry off the old seal from the adhesive.
• Scissors – To cut the gasket to size if required.
• Hair Dryer – To warm and soften the new gasket for fitting.
• Towels – To dry the gasket and clean up any spills.
• Gloves – Protect your hands from adhesive residue.
• Masking Tape – To hold the gasket in place temporarily.
• Sealing Putty – To seal any gaps between the gasket and refrigerator body.

Step-by-Step Guide

Follow these steps carefully when replacing your faulty refrigerator door seal:

Step 1: Confirm the Seal is Faulty

Before ordering a replacement gasket and attempting to install it, confirm first that your current seal is actually worn out and allowing cold air to leak.

You can do this through the simple paper test:

1. Cut out strips of paper, about 3 inches wide.
2. Close the refrigerator doors tightly.
3. Working your way around the door seals, try to slide the paper strips in at various points between the door gaskets and the refrigerator cabinet.
4. Check if you feel significant resistance or not.

If the paper slips in and out very easily at any point, then cold air is likely leaking from a faulty gasket seal. If however, you feel noticeable drag and friction, then your current seal may still be functional.

Perform this test all the way around each refrigerator door gasket to identify any weak spots. This will confirm whether you need a new seal before purchasing one.

Step 2: Order the Right Replacement Gasket

Once you have confirmed seal failure through testing, next you need to purchase the correct replacement gasket for your specific refrigerator make and model.

To find the right gasket:

• Check the owner’s manual or service manual for the replacement part number.
• Search on the manufacturer’s official website using your refrigerator model number.
• Take the old gasket to the hardware store for comparison.
• Measure the length and thickness of old gasket and order closest match online.

Order the new seal well in advance so you have it ready before removing the old unit.

Step 3: Prepare and Fit the New Gasket

To make installing it easier, you need to prepare the new replacement gasket first:

1. Check dimensions – Verify the new gasket is the right length to fit your refrigerator door perimeter.
2. Test flexibility – The rubber seal should be flexible enough to bend around corners easily.
3. Soak in warm water – Place the gasket in a tray of warm water for 3-5 minutes. This makes the rubber more pliable for fitting onto the door.
4. Dry thoroughly – Wipe away all water so the self-adhesive back can stick properly later.

With the warm water treatment, you can now fit the gasket onto the door temporarily to ensure proper shape and length.

Use short strips of masking tape to lightly hold it in place. Remove again once you are satisfied with the test fit.

Step 4: Remove the Faulty Door Gasket

After test fitting the new gasket, next you need to remove the current worn-out door seal. Follow these steps to remove properly:

1. Start unfastening – Using a flat screwdriver, begin undoing any visible screws or fasteners around the perimeter.
2. Locate adhesive strip – Run your fingers underneath the gasket to find where it is stuck to the door frame using adhesive.
3. Apply heat – Use a hairdryer to warm the adhesive for 1-2 minutes. This softens it for easier removal.
4. Slowly peel away – With the putty knife, gently insert under the gasket lip and carefully peel back the seal working your way around.

Precautions when removing:

• Take care not to rip the old gasket during removal.
• Watch for and remove any stubborn screws first.
• Protect the door surface from scratches using tape.
• Work slowly to minimize adhesive residue left behind.

Completely remove the old door seal and scrape away any leftover adhesive foam on the door frame in preparation for fitting the new gasket.

Step 5: Install the Replacement Gasket

With the door frame prep complete, next you need to install the replacement refrigerator door seal properly:

1. Apply adhesive – Run an adhesive foam tape all the way around the back of the gasket and remove the protective film.
2. Position one end – Line up one end of the gasket at the start point ensuring no gaps.
3. Press to adhere – Apply even pressure as you affix the adhesive gasket to the door surface working your way around.
4. Seal corners – Pre-bend the gasket at the corners for smooth bends before adhering that section.
5. Check for gaps – Examine the door perimeter for any spots with poor adhesive contact or visible gaps.
6. Seal gaps – Use silicone sealant on minor gaps between gasket and door to prevent air leaks.

Take care not to press too firmly or stretch the gasket unevenly during installation. Finally, screw on any necessary trim fasteners to hold the new seal securely in place.

Step 6: Test the New Gasket for Air Leaks

With the replacement seal fully installed, the final step is to test for leaks around the new gasket perimeter.

Repeat the paper test once more after installation:

1. Tightly close the refrigerator doors.
2. Working your way around the door seals, try to slide paper strips in at various points between the door gaskets and the refrigerator cabinet.
3. Check if paper slips in easily indicating air leak problems.

There should now be significant friction against the paper around the entire new seal. If air gaps still persist, you may need to refit that seal section or use more sealing putty to fill gaps.

Tips and Precautions

Follow these useful tips and exercise safety precautions when replacing refrigerator door seals yourself:

• Check door alignment before installing new gasket. Misaligned doors exert uneven force on gaskets resulting in premature seal failure.
• Use mild detergent and water to thoroughly clean door frame channels before fitting new seal. Ensure surface is grease-free for best gasket adhesive contact.
• When prying off old seal, always protect door surface from putty knife scratches using painters tape shields.
• Dry fitted gasket thoroughly after soaking and test correct shape using masking tape before final installation with adhesive.
• Ensure even compression pressure when affixing new seal onto door. Uneven pressure can result in gaps between gasket and frame.
• Affix higher compression loads at door corners for tighter bends without kinks.
• After installation, allow 12-24 hours for adhesive to fully cure before testing seal.
• Avoid over-stretching seals during replacement. This leads to tears and damage to the new gasket.
