What is the upper hinge cam riser?

The upper hinge cam riser is a small plastic part located at the bottom of the freezer door, right above the door hinge. Its job is to control the opening and closing motion of the freezer door so it can close tightly and provide a good seal.

Over time, the upper hinge cam riser can wear out or break. If the cam riser is damaged, the freezer door will fail to seal completely when closed, and cold air can escape from the freezer. Warm air can also seep in, which could cause ice to build up and food to spoil.

Keep safety first

Anytime you repair an appliance, safety should always come first. Follow these precautions when working on your Samsung refrigerator:

• Always power off and unplug your appliance or switch off the circuit breaker before attempting any maintenance or replacement work. This keeps you safe by preventing any risk of electric shock.
• Turn off the water supply to prevent leaks and water damage.
• Be careful when handling the fridge doors. The doors are heavy and awkward to maneuver, so grab a sturdy stool, ladder or extra person to help if needed.
• If the appliance has recently been used, give it plenty of time to cool down before working on it.
• Take your time and don’t rush while working to prevent accidents and personal injuries.
• Work in a well-lit area so you can clearly see and access appliance parts.
• Keep your workspace free of clutter and other obstacles. Keep children and pets away from the work area.
• Never work on internal parts with wet hands. Make sure the work area is completely dry.
• Check the user manual to see if there are specific installation or safety instructions related to your appliance or replacement part.
• Be gentle when handling or removing parts. Excessive force might damage the appliance or cause personal injury.
• Wear insulated work gloves to protect your hands from sharp metal parts and debris.
• When working with wires, avoid touching any exposed wires or terminals. If you need to touch a wire, use a non-conductive tool or wear insulating gloves to prevent electrical shock.
• Don’t test live voltage with a multimeter if you’re unfamiliar with how to prevent short-circuiting.
• Consider wearing safety glasses and/or a dust mask when working with chemicals, dust or a large amount of debris to prevent irritation or injury.

Replacement instructions

Step 1: Remove the toe grill

The toe grill is the ventilated cover at the bottom front of the refrigerator. Removing this provides access to the water lines and lower hinge.

1. Turn off the fridge and disconnect it from the power source.
2. Make sure the fridge water supply is disconnected. Find the shut-off valve for the fridge’s water line so you can turn off the water.
3. Use a Phillips screwdriver to remove the three screws securing the toe grill.
4. Set the toe grill aside.

Step 2: Disconnect the water lines

1. Find the two water lines running from the bottom hinge into the refrigerator cabinet. You’ll need to disconnect them to detach the freezer door.
2. Use a 3/8″ open-ended wrench to loosen the compression fittings on both water lines. This will release the lines from the connector stems.
3. Have a towel ready to catch any water remaining in the lines.
4. Detach both water lines from the connector stems.

Step 3: Remove the top hinge cover

With the doors closed, move to the top of the refrigerator.

Step 4: Disconnect the wiring harness

The wiring harness has two plugs that connect to the electronics in the hinge cover.

1. Press the release tabs on both plugs to disconnect them.
2. Remove the single Phillips screw that’s holding the green ground wire to the hinge.

Step 5: Detach the top hinge

1. Use a 10mm socket wrench to remove the three 10mm bolts securing the top hinge.
2. Support the freezer door as you remove the last bolt.
3. Lift the top hinge straight up to detach it from the cabinet.
4. Rest the freezer door on top of the fresh food door.

Step 6: Remove the freezer door

1. Support the weight of the door as you lift it up off the bottom hinge pin.
2. Tilt the door slightly outward to make room for the water lines.
3. Gently pull the water lines out from the bottom hinge as you remove the door.
4. Gently set the door down on its side.

Step 9: Replace the top hinge

1. Hold the top hinge in place over the aligned screw holes.
2. Insert the two outer 10mm bolts and tighten them.
3. Align the door and insert the center bolt before tightening all three bolts securely with the socket wrench.

Step 10: Reconnect the wires and cover

1. Reattach the two wiring harness plugs to the connectors in the hinge cover.
2. Replace the ground screw.

4. Insert and tighten the two Phillips screws.
