DIY: How to Replace a Whirlpool WP3400918 Retainer

Step 1: Gather the necessary materials. You will need a Phillips head screwdriver, a small flathead screwdriver, and the new WP3400918 retainer.

Step 2: Unplug the appliance. Before you begin your repair, always unplug the appliance from the wall socket to prevent any electrical shock or damage.

Step 3: Remove the mounting screws. There may be 4-5 screws located on the bottom of the appliance that hold the retainer in place. Use your Phillips head screwdriver to remove them.

Step 4: Carefully pull the retainer out from beneath the appliance. If it’s stuck, use a small flathead screwdriver to gently pry it loose.

Step 5: Insert the new retainer. Make sure the four sides are aligned properly, then press it into place at the four corners.

Step 6: Replace the mounting screws. Secure the retainer with the screws you removed in Step 3.

Step 7: Plug the appliance back in. Once you’ve replaced the retainer, turn the power back on to make sure everything is functioning properly.

You’ve successfully replaced the Whirlpool WP3400918 retainer!
