Samsung RF28F5001SR Ice Maker Leaking Water — Causes & Fix

Samsung RF28F5001SR Ice Maker Leaking Water: Complete Troubleshooting Guide

Hey there, I’m Drew Callahan, and if there’s one thing I’ve learned from my extensive experience fixing appliances—over 80,000 miles across North America in three different rigs—is that a leaking ice maker in your Samsung RF28F5001SR French door refrigerator can be a pesky issue. This situation requires systematic diagnosis before jumping into repairs. Water pooling in or around the ice maker compartment can originate from several sources, each with its own solution. Buckle up, because I’m about to guide you through identifying the exact cause of the leak and provide step-by-step instructions to fix it.

Safety Warning

⚠️ Electrical Safety: Before diving into any work on your RF28F5001SR, make sure to unplug the refrigerator from the electrical outlet. The ice maker assembly has electrical components, including the water inlet valve solenoid and the heating element. Testing these components while the appliance is powered could be hazardous. Give it at least 15 minutes after unplugging for any electrical charge to dissipate before you start handling internal components.

⚠️ Water Damage: If your ice maker is leaking, there’s a chance that water has already damaged nearby components. Be cautious with any standing water and make sure to dry the area thoroughly to avoid electrical hazards.

Step 1: Confirm the Leak Source

Identifying the location and nature of the water leak is crucial as it significantly narrows down the possible causes. Different symptoms can indicate different issues within the RF28F5001SR ice maker assembly.

Water Under the Ice Bin

If you’re finding water pooled beneath the ice bin but the ice itself is dry, the problem usually lies with water being dispensed during the ice maker’s fill cycle but failing to freeze properly, or water leaking from the fill cup. This water can drain down through the opening of the ice bucket. Common culprits include an overfilled ice maker tray due to a faulty water inlet valve or ice blockages in the fill tube that prevent proper water flow.

Wet or Mushy Ice

If the ice cubes in your RF28F5001SR are wet, mushy, or partially melted, that’s a telltale sign that water is present during the freezing cycle. This can happen if the ice maker mold heater activates at the wrong time, condensation from the heating element occurs, or water continues to enter the mold after the fill cycle has ended. The mold heater is designed to create a thin layer of heat to help release the ice cubes, but if it cycles too frequently or for too long, it will melt the ice.

Water on the Freezer Floor

If you notice water pooling at the bottom of the freezer compartment, it could indicate several issues. First, check if the water is localized under the ice maker or if it’s spread across the entire floor. If the latter is true, the defrost drain system might be the issue, not the ice maker. If it’s localized under the ice maker, the water inlet valve or fill tube is likely the culprit. Don’t jump to conclusions that the ice maker is faulty—the defrost drain system is commonly mistaken for an ice maker leak.

Understanding the RF28F5001SR Ice Maker Assembly

The ice maker assembly in the Samsung RF28F5001SR consists of several key components that work together to produce ice:

• Water inlet valve: Controls water flow into the ice maker mold. Part number DA62-00038A for RF28F5001SR models.
• Fill cup and fill tube: Directs water from the inlet valve to the ice maker mold.
• Ice maker mold: Freezes water into individual cubes. Contains an electric heating element for release.
• Ice room door seal: Prevents cold air loss and water escape when dispensing ice.
• Motor and auger: Advances frozen ice cubes to the dispenser.

Diagnosing the Water Inlet Valve

The Most Common Cause: Faulty Water Inlet Valve

When it comes to ice maker leaks, the water inlet valve (part number DA62-00038A on the RF28F5001SR) is often the primary suspect. This solenoid-operated valve opens and closes to control water flow into the ice maker mold. If the valve gets stuck or wears out, it can either fail to close completely—causing a continuous water dribble into the mold—or fail to open properly, leading to incomplete fills that keep repeating.

Testing for a Dripping Valve

To test whether the water inlet valve on your RF28F5001SR is leaking, follow these steps:

1. Unplug the refrigerator and find the water inlet valve at the back of the unit, typically on the lower right side of the freezer compartment.
2. Inspect the valve outlet connection where the water lines attach. Look for active dripping or wet residue.
3. If you see water dripping from the outlet when the unit is unplugged and the solenoid is de-energized, the valve seat is damaged, and the valve needs replacing.
4. If water drips only when the refrigerator is plugged in and the ice maker cycles, the solenoid coil may be stuck open, requiring valve replacement.
5. Use a multimeter set to the 2 kΩ (ohms) scale to test the solenoid coil resistance. Disconnect the wire harness from the valve solenoid and touch the multimeter probes to the solenoid terminals. A reading between 500-1000 ohms indicates a good coil. A reading of 0 ohms or infinity indicates a failed solenoid requiring valve replacement.

Overfilling and the RF28F5001SR Fill Cycle

A malfunctioning water inlet valve (DA62-00038A) will keep the fill cycle running longer than the standard 5-7 seconds, causing the ice maker mold to overfill. Excess water will spill out of the mold into the ice bin area, where it either drains to the bottom or partially refreezes, creating wet or misshapen ice. This is one of the most frequently reported issues with the RF28F5001SR.

Inspecting the Fill Cup and Fill Tube

Ice Blockage in the Fill Tube

The fill tube on your RF28F5001SR delivers water from the inlet valve to the ice maker mold. If this tube freezes due to subfreezing temperatures or if ice cubes jamming the mold back up into the tube, water will be redirected and overflow into the ice bin.

How to Clear Ice Blockages

1. Unplug the RF28F5001SR and remove the ice bucket by lifting it straight out of the freezer.
2. Look up into the ice maker cavity to locate the fill cup—a small plastic cup directly below the fill tube opening.
3. If ice has accumulated in or around the fill cup, use a plastic scraper or old credit card to gently break it apart. Avoid metal tools that could damage the plastic components.
4. Pour warm (not boiling) water down the fill tube opening to melt any ice blockages inside the tube itself. Collect the water with towels or a pan.
5. Inspect the fill cup for cracks. A cracked fill cup will cause water to spray into the ice bin rather than flow into the mold. If cracked, the fill cup assembly must be replaced.
6. Reinsert the ice bucket and allow the RF28F5001SR to complete 2-3 ice making cycles before determining if the issue is resolved.

Ice Room Door Seal Inspection

How the Ice Room Door Seal Works

The ice room (ice compartment) on the RF28F5001SR has a separate door equipped with a rubber gasket seal that closes when you’re not actively dispensing ice. If this seal is torn, compressed, or misaligned, warm air can seep into the cold ice room, causing moisture to condense on the cold ice, which creates water that pools at the bottom. Additionally, if the seal doesn’t close properly, water can leak out the front of the ice door when ice is being dispensed.

Checking the Ice Door Seal

1. Open the ice room door on your RF28F5001SR by pushing on the ice bucket until the door pops open.
2. Inspect the rubber gasket running around the perimeter of the door opening. Look for visible cracks, tears, or areas where the gasket is compressed and lacks springiness.
3. Close the door and ensure the gasket seals completely. If there are visible gaps around the edges, the door is not sealing properly.
4. Check that the ice room door closes smoothly without sticking. If the door binds or closes slowly, the hinge may be bent or the door frame may be damaged.
5. If the gasket is damaged, the ice door seal gasket (part number DA61-00289A) can be replaced. If the door itself is cracked or the frame is bent, the ice room door assembly may need replacement.

Examining the Ice Tray for Cracks

Hairline Cracks in the Ice Maker Mold

The ice maker mold in your RF28F5001SR is made of plastic that can develop hairline cracks over time due to repeated freezing and heating cycles. These cracks allow water to escape during the fill cycle, causing water to pool beneath the ice bin instead of freezing into cubes.

How to Inspect the Mold

1. Unplug the RF28F5001SR and remove the ice bucket.
2. Look directly into the ice maker cavity. The mold is the plastic tray with individual ice cube compartments.
3. Run your finger along the inside surfaces of the mold, feeling for any rough areas or cracks. Pay close attention to the corners and seams where cracks are most likely to develop.
4. Shine a flashlight into the mold to get a better view of potential cracks. Hairline cracks may be hard to see without good lighting.
5. If you discover cracks, the ice maker assembly must be replaced. The mold is not sold separately; part number DA97-01953A is for the complete ice maker assembly for RF28F5001SR models.
6. Note the location of the crack. If water is leaking from a specific point, you can temporarily seal it with clear waterproof silicone caulk as a short-term fix while you order the replacement part.

Understanding the Ice Maker Mold Heater Cycle

How the Heating Element Works

The ice maker mold in the RF28F5001SR includes an electric heating element that briefly warms the bottom of the mold to help release frozen ice cubes. This heating cycle is critical for ice ejection. However, if the heater stays on for too long or cycles too frequently, it will melt the ice, leading to wet, mushy cubes and water accumulation in the bin.

Condensation from the Heater

During the heating cycle, condensation naturally forms on the cold surfaces of the ice maker cavity in your RF28F5001SR. This moisture is normal and should drain away. However, if the defrost drain or ice maker drain is blocked, this condensation will accumulate as liquid water. The mold heater itself doesn’t leak water; rather, it creates conditions for condensation that may not drain properly if the drainage system is compromised.

Testing the Heater Element

1. Unplug the RF28F5001SR and locate the heating element at the bottom of the ice maker mold. It appears as a thin wire or resistive element.
2. Disconnect the wire harness from the heater terminals.
3. Set your multimeter to the 200 Ω (ohms) scale.
4. Touch the multimeter probes to the heater terminals. A reading between 30-100 ohms indicates a functioning heater. A reading of 0 ohms or infinity means the heater has failed and should be replaced as part of the ice maker assembly (part number DA97-01953A for RF28F5001SR).
5. If the heater tests good electrically but the ice is still wet, the issue is likely the control module cycling the heater too frequently. At this point, I suggest contacting Samsung service for diagnostics.

The Defrost Drain System (Not Ice Maker Related)

Why This Is Commonly Mistaken for an Ice Maker Leak

Many homeowners think their RF28F5001SR is leaking from the ice maker when, in fact, the leak is coming from the refrigerator’s defrost system. The defrost drain collects condensation from the evaporator coils and routes it to a drain pan at the bottom of the unit. If this drain becomes blocked by ice or debris, water will pool on the freezer floor, directly beneath the evaporator coils—which just so happens to be near the ice maker area.

How to Identify a Defrost Drain Problem

1. Check if the water is spreading across the entire bottom of the freezer or localized only under the ice maker. Defrost drain leaks typically cause widespread pooling.
2. Unplug the RF28F5001SR and find the defrost drain line at the back wall of the freezer compartment, typically near the bottom. It’s a small plastic tube.
3. Insert a straightened wire or pipe cleaner through the drain opening to clear any blockages.
4. Pour a small amount of warm water down the drain to verify it flows freely. Water should drain without backing up.
5. If water backs up, the drain line may be blocked further downstream. You might need to access the drain line from the back of the refrigerator for complete cleaning.

Step-by-Step Water Inlet Valve Replacement for RF28F5001SR

If you’ve determined that the water inlet valve (part number DA62-00038A) is the source of the leak, follow these detailed steps to replace it.

Tools and Materials You’ll Need

• Replacement water inlet valve (DA62-00038A) for RF28F5001SR
• Adjustable wrench or 7/8″ wrench
• Flathead screwdriver
• Towels and a pan to catch water
• Wire strippers (optional)
• New water supply line (optional, if old line is damaged)

Detailed Replacement Instructions

1. Unplug the refrigerator: Disconnect the RF28F5001SR from the electrical outlet. This step is critical for your safety. Allow 15 minutes for any residual charge to dissipate.
2. Turn off the water supply: Locate the water shut-off valve for your home’s water line to the refrigerator. Turn it clockwise until fully closed. If you can’t find the shut-off valve, contact a plumber before proceeding.
3. Remove the access panel: The water inlet valve is located at the back of the freezer compartment, typically behind a plastic access panel. Open the freezer door and locate this panel on the lower right side. Remove any screws holding it in place using a flathead screwdriver. Gently pull the panel away from the unit.
4. Locate the water inlet valve: The valve is a rectangular component about 3 inches long by 2 inches wide. It has three connection points: an inlet water line, an outlet line (typically running upward to the ice maker), and an electrical harness. The part number DA62-00038A will be printed on the valve body.
5. Disconnect the electrical harness: Carefully pull the wire harness straight out from the solenoid coil. Make sure not to twist or bend the connector, as that could damage the terminals.
6. Disconnect the water supply line: Using an adjustable wrench, grip the large hexagonal nut on the inlet side of the valve. While holding the valve body steady with your other hand, turn the nut counterclockwise to loosen the connection. Once loose enough to turn by hand, carefully unscrew the nut and remove the water line. Expect a small amount of water in the line—keep towels handy.
7. Disconnect the outlet water line: Use the same wrench method to disconnect the outlet line that runs to the ice maker. This connection is usually a compression fitting. Pay attention to the orientation of this fitting for reinstallation.
8. Remove the mounting bracket: The valve is typically held in place by a metal bracket with one or two screws. Remove these screws with your flathead screwdriver and gently slide the old valve out of the bracket.
9. Install the new valve: Remove the new DA62-00038A valve from its packaging. Slide it into the mounting bracket, ensuring it sits flush against the back support. Reinstall the mounting bracket screws.
10. Reconnect the water outlet line: Thread the outlet line connection back onto the new valve’s outlet port. Hand-tighten first, then use the wrench to snug it firmly but not excessively tight. Over-tightening compression fittings can crack the valve body.
11. Reconnect the water inlet line: Reattach the incoming water supply line to the inlet port of the new valve. Hand-tighten, then use the wrench to secure it. Open the water shut-off valve in your home to restore water pressure. Check for any leaks at the connections—if water drips, turn off the water and tighten the fitting another quarter turn.
12. Reconnect the electrical harness: Align the wire harness connector with the solenoid coil terminals on the new valve. Push straight in until you hear or feel a click, indicating a secure connection.
13. Reinstall the access panel: Push the plastic access panel back into place and secure it with the screws you removed earlier.
14. Plug in and test: Plug the RF28F5001SR back into the electrical outlet. Listen for the water inlet valve to cycle—you should hear a brief “click” or buzzing sound followed by water flowing into the ice maker. Allow 2-3 complete ice making cycles (approximately 4-6 hours) before checking for any leaks.

The Water Filter That Often Gets Blamed for Ice Maker Leaks (And Sometimes Actually Is)

Before you start dismantling the ice maker assembly, I recommend swapping out your water filter—a clogged or failing Samsung DA29-00003G is responsible for more ice maker leaks than most people realize. The back-pressure forces water to find alternate routes through the system. In my experience, I’ve diagnosed plenty of “ice maker leak” calls that turned out to be a filter that hadn’t been replaced in two years.

What works

• Direct fit for the RF28F5001SR without adapter nonsense—the cartridge slides in, twists, and locks; no guessing about compatibility.
• Reducing back-pressure in the water line stops ice maker overflow and dripping that appears to come from the unit itself but actually originates upstream in the supply line.
• The replacement process takes 30 seconds and is the first troubleshooting step I recommend before pulling panels—it eliminates an entire class of leak causes immediately.

What doesn’t

• Won’t fix leaks caused by frozen supply lines, cracked water inlet valves, or damaged tubing inside the door—filter replacement is diagnostic, not a universal cure.
• OEM Samsung filters are pricier than third-party options, and you’ll need to replace it every 6 months regardless, so budget accordingly if water quality is an ongoing concern.

I’ve had jobs where I jumped straight to ice maker valve replacement only to discover the real problem was a filter that had calcified shut, forcing water to bypass the system entirely. Always start with the filter swap first—it’s free diagnosis time. Grab a AQUA CREST AQF-FF11B Refrigerator Water Filter and rule out the simplest culprit before you commit to deeper repairs.
