Self-closing refrigerator doors are often listed as a feature on many refrigerator product sales sheets. Both refrigerator and freezer doors have hard nylon cams installed around the bottom hinge pin and in the bottom of the door. The design of the cam uses the weight of the door to ensure it shuts on its own when gently pushed. Over time, the cams can wear and begin making a clunking or popping noise as the door opens or closes. Replacing the cam takes care of the noise and ensures your doors continue to close by themselves.
Reach behind your refrigerator to pull the power cord from the wall outlet. You do not have to worry about turning off the water supply to the icemaker, as without power the water does not run through the refrigerator.
Open up your freezer door and empty the contents of the door into an ice chest. The repair should not take over 30 minutes, so it may not be necessary to place the remainder of the freezer contents in the ice chest. You replace the freezer and refrigerator door cams in the same manner, but there are two or three extra steps when replacing the freezer door cam that can be omitted when replacing the refrigerator door cam.
Open the bottom door -- if it is not the freezer -- to access the toe kick grill along the bottom of the refrigerator. The grill uses tension clips to hold it to the bottom of the refrigerator, so it only requires grabbing the grill with your hands and gently pulling it from the refrigerator. Removing the grill exposes the water line connections beneath the freezer side of the refrigerator. Place the grill aside and shut the door, again, if it is not the freezer.
Place a small towel underneath the water line connections. Locate the connector holding the water line from the freezer door to the water line coming from beneath the refrigerator. Press down on the red disk at the top of the connector while pulling the line attached to the freezer door out of the connector. Shut the freezer door.
Remove the screws from the cover on top of the freezer door that hides the hinge. Lift the cover and expose the electrical connections to the freezer door. Grab the two sides of the wire harness holding the wires together and pull it apart. Your freezer door may not have this wire harness.
Unscrew the hex-head screws holding the freezer door hinge to the body of the refrigerator with a nut driver. Open the freezer door slightly and lift it from the bottom hinge pin. The freezer door could be heavy, so ask an assistant to help move the freezer door to a stable work surface.
Look on the bottom of the freezer door for the door cam. It will be either black or white nylon and appear to have a jagged edge. Some cams slip into the hole in the bottom of the door while others are held in the bottom of the door with a screw. Remove the screw from the freezer door cam, if applicable.
Slide a flat-blade screwdriver between the cam and the bottom of the freezer door. Pry the cam from the door. Insert the new cam in its place, gently tapping it with the head of your screwdriver and replace the screw if necessary.
Remove the screw holding the cam around the bottom door hinge on the freezer. Slide the cam off the hinge. Slide a new cam on the hinge and replace the screw. Coat the hinge cam with silicone based grease.
Lift the freezer door back onto the bottom hinge. Ensure the water line attached to the freezer door slides through the retainer on the bottom of the refrigerator. Carefully set the door in place.
Attach the freezer door hinge to the top of the refrigerator using the screws you previously removed. Do not tighten the screws. Place a level on top of the freezer door. Make sure the door is level before tightening the hinge screws.
Reconnect the wire harness. Replace the hinge cover and secure it with the screws you previously removed. Reconnect the water line at the bottom of the refrigerator.
Open both the refrigerator and freezer doors. Snap the toe kick grill onto the bottom of the refrigerator. Place the food from the ice chest back into the freezer door. Shut the doors and plug the refrigerator into the wall.
