Samsung RF28R7351SR Internal Water Lines & Ice Room Door Gasket Replacement

Samsung RF28R7351SR Internal Water Line and Ice Room Door Gasket Repair Guide

Hi, I’m Drew Callahan. After traveling over 80,000 miles across North America in three different rigs, I’ve gained hands-on experience fixing appliances in every climate imaginable. From replacing parts on dryers, washers, fridges, and ice makers in garages, campgrounds, and even RVs, I’ve tackled it all out of necessity. Today, I’m diving into the Samsung RF28R7351SR, a premium French door refrigerator that comes with an integrated ice maker and dispenser system. Like any fridge with ice-making capabilities, its internal water delivery system needs regular maintenance. In this guide, I’ll take you through the steps to replace the internal water lines and the ice room door gasket—two common repairs for this model. If you’re dealing with water pooling in the freezer or ice buildup around the ice chute, stick with me as we walk through the diagnosis and repair process step-by-step.

⚠️ Safety Warning

Before you start any repair on your Samsung RF28R7351SR, keep safety in mind:

• Disconnect the power: Unplug the refrigerator from the wall outlet or turn off the circuit breaker. We don’t want to work on a powered appliance.
• Turn off the water supply: Find the water shut-off valve behind or near your refrigerator and turn it clockwise to stop the water flow.
• Allow pressure to release: Wait 5 minutes after disconnecting power to let any residual water pressure in the lines dissipate.
• Expect water drainage: Be ready with towels and a shallow pan. Residual water may spill when you disconnect the water lines.
• Do not force frozen components: If ice has built up around the water lines or the ice room door, allow 30 minutes for the freezer to warm slightly before attempting removal.

Understanding the Water Line System in the RF28R7351SR

The Three Main Internal Water Lines

Your Samsung RF28R7351SR has three critical internal water delivery lines:

• Ice Maker Fill Tube: This tube runs from the back of the refrigerator cabinet through the freezer compartment to the ice maker mechanism. It has a heating element designed to prevent water from freezing inside the line.
• Water Dispenser Line: This line delivers filtered water from the main supply line to the dispenser outlet on the refrigerator door. It carries both cold and room-temperature water based on your dispenser settings.
• Ice Room Connector Line: This line carries water from the main filter housing to the ice maker compartment, serving as a secondary supply line for the ice-making mechanism.

Common Symptoms of Internal Water Line Failure

Recognizing the warning signs of a failing water line can help you address issues before they lead to extensive damage:

• Water visible inside the freezer compartment: This usually appears as pooling water on the freezer floor or excessive frost buildup.
• Wet bottom of freezer: A common symptom of a cracked fill tube, where water drips down and pools at the base of the freezer section.
• Ice maker produces no ice: No water reaching the ice maker mechanism when the fill tube is blocked or disconnected.
• Weak or no water from dispenser: This indicates a problem with the dispenser line or blockage in the system.
• Water pooling under the refrigerator: Suggests a leak in the ice room connector or disconnection at the water inlet valve.
• Frost accumulation around the ice maker compartment: Often caused by humidity escaping through a failed ice room door gasket and freezing.
• Visible cracks or splits in tubing: Any visible tubing that appears cracked should be replaced immediately.

How to Replace the Ice Maker Fill Tube on the RF28R7351SR

Parts and Tools You’ll Need

• Replacement ice maker fill tube assembly (Samsung part number DA97-02194D or equivalent for RF28R7351SR)
• Replacement heating element for fill tube (if not included with tube assembly)
• Phillips head screwdriver
• Flathead screwdriver
• Adjustable wrench (for water line connections)
• Flashlight or headlamp
• Towels and catch pan
• Needle-nose pliers

Step 1: Prepare the Refrigerator

1. Unplug your Samsung RF28R7351SR from the electrical outlet.
2. Locate the water shut-off valve, typically behind the refrigerator or in an adjacent cabinet. Turn it clockwise to fully close.
3. Open the freezer door and let it warm for 5-10 minutes. This helps loosen any ice buildup around the fill tube area.
4. Put towels on the freezer floor to catch any water drainage.

Step 2: Remove the Ice Maker Assembly

1. Find the ice maker unit inside the freezer compartment, usually in the upper corner.
2. There are three Phillips head screws holding the ice maker to the freezer wall—one at the top and two at the bottom corners.
3. Remove all three screws with your Phillips head screwdriver, keeping them safe for reinstallation.
4. Gently pull the ice maker assembly toward you. Note the orientation of the plastic water supply line connected to the back before disconnecting.
5. Disconnect the water line by pinching the quick-disconnect fitting or unscrewing it, depending on your model. Some RF28R7351SR models have push-fit connectors that release when you squeeze the collar.
6. Set the ice maker assembly aside carefully on a clean surface. Don’t drop it; internal parts can be fragile.

Step 3: Access the Freezer Back Panel

1. The fill tube runs along the back interior wall of the freezer, so you need to access this panel.
2. Look for the back panel of the freezer compartment, usually held by clips or screws along the top edge.
3. If clipped: Gently pull the top of the panel toward you and lift it free from the clips.
4. If screwed: Remove the Phillips head screws along the top edge with your screwdriver.
5. You might need to remove shelving to access the panel completely; set these aside carefully.
6. Once the panel is free, you’ll have direct access to the internal water lines running vertically along the back wall.

Step 4: Locate and Inspect the Fill Tube

1. Use your flashlight to examine the back wall of the freezer compartment. The ice maker fill tube is a white or clear plastic tube, about ½ inch in diameter.
2. This tube has a heating element wrapped around it, which appears as a thin wire or metal band spiraling around it to prevent water from freezing.
3. Trace the tube from top to bottom. Look for any visible cracks, splits, or white crystalline deposits (mineral buildup) indicating a leak.
4. If you see cracks, the tube must be replaced. Even small cracks can worsen and lead to water damage over time.
5. Check the heating element connections—there should be two small wires leading from the heating element to electrical connectors. If these are disconnected, that’s your issue—the unheated line froze and cracked.

Step 5: Disconnect the Old Fill Tube

1. At the top of the RF28R7351SR freezer compartment, locate where the fill tube connects to the water inlet valve or main supply line. This connection is usually a compression fitting or quick-connect.
2. If it’s a compression fitting: Use your adjustable wrench to hold the hex nut while turning the fitting counterclockwise. Have your towel ready—water may drip.
3. If it’s a quick-connect: Locate the small collar or clip on the fitting. Press or slide it to release the tube; water will drip, so be prepared.
4. Disconnect any wires from the heating element, noting their positions or taking a photo for reference.
5. Remove any clips or brackets holding the tube to the freezer wall. These are usually small plastic clips that unsnap or unscrew.
6. Carefully pull the old tube down and out of the freezer. If it’s stuck with ice, be patient and gentle.

Step 6: Install the New Fill Tube

1. Unpack your replacement fill tube assembly for the RF28R7351SR and inspect it for damage.
2. If the heating element is separate, wrap it around the new tube following the same spiral pattern as the old one, securing it with the provided clips.
3. Reconnect the heating element wires to their original connectors, pushing firmly until you hear or feel a click.
4. Route the new tube along the same path as the old one, securing it with clips at regular intervals (every 12-18 inches) to prevent vibration damage.
5. Connect the top of the tube to the water inlet valve using the same method as the original connection (compression fitting or quick-connect). Tighten firmly but don’t overtighten, as this can crack compression fittings.
6. Ensure the heating element is connected fully with no exposed wires.

Step 7: Reconnect the Ice Maker

1. Reconnect the water supply line to the ice maker by pushing the quick-connect fitting firmly onto the tube stub until you hear a click or by screwing the compression fitting clockwise.
2. Reinstall the ice maker assembly by aligning it with the three screw holes in the freezer wall.
3. Insert and tighten the three Phillips head screws—snug is sufficient, don’t overtighten.

Step 8: Reassemble and Test

1. Reinstall the freezer back panel, securing it with clips or screws as originally configured.
2. Replace any shelving you removed.
3. Turn the water shut-off valve counterclockwise to restore water pressure.
4. Plug your Samsung RF28R7351SR back into the electrical outlet.
5. Wait 5 minutes for the system to pressurize.
6. Check all connections for leaks. You should see no water dripping or pooling.
7. The ice maker should begin producing ice within 24 hours. Keep an eye on the freezer floor for any water accumulation over the next few days.

Ice Room Door Gasket Replacement for the RF28R7351SR

Understanding the Ice Room Door and Gasket

The ice room door is a small access door on many Samsung refrigerators, including the RF28R7351SR, separating the ice maker compartment from the main freezer space. The gasket (or seal) is a rubber or silicone strip that runs around the perimeter of this door, maintaining temperature separation and preventing warm air from entering the ice maker compartment, which would cause excessive frost buildup and ice production problems.

What Causes Ice Room Door Gasket Failure

• Tearing and splitting: Over time, the gasket material can become brittle from repeated freezing and thawing cycles, allowing cold air to escape through small tears.
• Warping from ice buildup: A failing gasket allows warm air to leak in, causing frost to accumulate around the door frame and further warping the gasket.
• Compression loss: The gasket loses its ability to compress and seal tightly after years of opening and closing the door, which is normal wear for the RF28R7351SR.
• Chemical degradation: Exposure to water, minerals, and cleaning chemicals can degrade the gasket material over time.
• Manufacturing defects: Occasionally, a gasket can be defective from the factory and fail prematurely.

Symptoms of a Failing Ice Room Door Gasket

• Excessive frost or ice buildup around the ice room door frame
• Ice chute area feels unusually warm to the touch
• Visible gap between the door and frame when closed
• Door does not seal tightly—you can pull it open with light pressure
• Water leaking from the ice dispenser chute
• Ice maker producing cloudy or hollow ice cubes
• Rubber gasket material visibly torn, cracked, or peeling away from the door frame

Finding the Correct Replacement Gasket for Your RF28R7351SR

The Samsung RF28R7351SR uses gasket part number DA63-04326A or DA63-04326E depending on the production date. To ensure you order the correct gasket:

• Locate your refrigerator’s model and serial number on the sticker inside, typically on the right wall near the top.
• Search for “RF28R7351SR ice room door gasket” with your full model number to verify compatibility.
• The gasket assembly comes with adhesive backing. Some aftermarket versions require separate adhesive purchase.
• Measure your ice room door frame: most RF28R7351SR models have a gasket approximately 22 inches wide and 30 inches tall, but verify before ordering.

Removing the Old Ice Room Door Gasket

1. Unplug your Samsung RF28R7351SR from the electrical outlet for safety.
2. Open the ice room door fully by pulling it toward you; this door provides access to the ice maker compartment.
3. Examine the gasket. It’s bonded to the door frame with adhesive. Starting at a corner, gently peel the gasket away from the frame using a plastic scraper or old credit card—avoid metal tools to prevent scratching.
4. Work your way around the perimeter, steadily pulling the gasket free. This can take several minutes, and some adhesive residue will remain.
5. Once the gasket is removed, use your plastic scraper to remove any remaining adhesive. Acetone or rubbing alcohol can help dissolve stubborn adhesive, but test on an inconspicuous area first.
6. Clean the entire door frame thoroughly with a damp cloth and dry it completely. Any dust or moisture will prevent the new gasket from adhering properly.

Installing the New Ice Room Door Gasket

1. Unpack your replacement gasket for the RF28R7351SR and check for any damage.
2. Most replacement gaskets come with self-adhesive backing. Do not remove the backing yet.
3. Test-fit the gasket to the door frame without removing the backing. It should fit snugly in the channel or groove around the perimeter.
4. If the gasket doesn’t fit properly, do not force it. Contact the supplier to verify you have the correct part for your RF28R7351SR model.
5. Starting at the top center of the ice room door frame, peel back about 6 inches of the adhesive backing.
6. Position the gasket and press it firmly into place, working from the center outward to avoid air bubbles.
7. Gradually peel away more of the backing as you work your way around the frame in a circular pattern.
8. Press firmly in corners to ensure the gasket seats properly where the frame changes direction.
9. Once the entire gasket is adhered, go around the frame again, pressing firmly with your hand or a roller for complete adhesion.
10. Close the ice room door and check the seal for snugness with no visible gaps.
11. Allow the adhesive to cure for 24 hours before using the refrigerator’s ice dispenser.

Distinguishing Between Ice Room Door Gasket and Ice Chute Flapper Leaks

On the RF28R7351SR, water can leak from the ice dispenser chute for two different reasons, making proper diagnosis critical for the correct fix.

Ice Room Door Gasket Leak

If the ice room door gasket is failing, you’ll likely notice:

• Water dripping from the exterior of the ice chute onto your glass or cup
• Frost buildup visible around the ice room door frame
• Water pooling inside the freezer near the ice room door
• A gap between the ice room door and frame that is visibly larger than normal

This happens because warm air leaks past the failed gasket, condensing on cold surfaces and running down into the ice chute mechanism. The solution is to replace the gasket as described above.

Ice Chute Flapper Leak

The ice chute flapper is a separate component—a small hinged door inside the ice dispenser that opens when you press the dispenser button. If this flapper is cracked or misaligned, water can leak past it. Signs of a flapper problem include:

• Water leaks only when the dispenser is actively used
• No visible frost buildup around the ice room door frame
• The ice room door gasket appears to be in good condition

The Ice Room Door Gasket That Stops Frost Buildup in Your Samsung RF28R7351SR

If you’re seeing frost accumulation around the ice room or noticing cold air escaping from that compartment, the door gasket is usually your first replacement—a bad seal lets warm air in and costs you money in energy bills. This is the part that fails most often on this model because it takes the temperature swing stress every time the ice maker cycles.

What works

• Exact fit for the RF28R7351SR ice room door—no trimming or modification needed, and it seats into the groove without forcing.
• The magnetic strip is strong enough to hold the door closed firmly without the seal feeling compressed or uneven after a few weeks.
• Stops frost and condensation buildup immediately once installed—you’ll notice the temperature consistency in that compartment stabilize within a day.

What doesn’t

• Installation requires removing the old gasket completely, which can be sticky if it’s been in place for years—you’ll need patience and warm water to soften the adhesive.
• Gasket alone won’t fix water line leaks or ice dispenser jams—if you’ve got water pooling inside, you’re dealing with a separate tubing or seal issue that needs diagnosis first.

I’ve had customers order this thinking it would fix a leaking ice maker, only to discover the real problem was a cracked water line underneath—so check for actual water pooling before you assume the door seal is the culprit. If frost or cold air escape is your actual symptom, this Samsung Refrigerator Door Gasket Seal is the right call.
