DA31-00342A — Samsung Refrigerator Part: What It Does, Symptoms & Replacement

Understanding the Problem

Brief explanation: DA31-00342A is an OEM Samsung part number that appears on refrigerator water/dispenser assemblies and related water-path housings on a number of Samsung fridge models. Because Samsung uses similar part numbers across a few related components, you should always verify the part against your refrigerator’s model diagram before buying. Typical problems this part is used to fix include no water from the dispenser, leaking at the dispenser/filter area, water that tastes or smells bad, or dispenser housing damage. Step-by-step diagnostic and replacement instructions: 1) Verify the part: locate your refrigerator’s model number (usually on a sticker in the fresh-food compartment or on the cabinet side). Cross-check the model number with the Samsung parts diagram online or with an authorized parts dealer to confirm DA31-00342A is the correct part for your model. If possible, remove and read the part number printed on the installed component to confirm it matches DA31-00342A. 2) Symptoms check: note exactly what is wrong — no water flow, slow flow, leaks near the dispenser/filter head, visible crack or broken plastic around the dispenser/filter area, or bad-tasting water. 3) Shut off utilities: unplug the refrigerator or switch off its breaker. Turn off the water supply to the fridge at the shutoff valve (under sink or at the wall). Drain any pressure by dispensing water briefly after the valve is closed. 4) Access the part: open the refrigerator/freezer and remove interior shelves or panels needed to reach the dispenser/filter housing or the area where the DA31-00342A is located. On many models this is inside the fresh-food door or behind a lower kickplate. 5) Inspect and isolate: visually inspect the housing for cracks, broken retention tabs, or mineral buildup. If flow is restricted, detach the water line and check for blockage. If leaking, identify whether the leak is at a fitting, O-ring, or from a cracked plastic housing. 6) Remove the old part: disconnect electrical connectors (press tabs to release) and carefully pull off any tubing (have a towel ready). Remove screws or clips holding the housing in place and free the part. Keep track of screws and orientation. 7) Prepare new part: compare the replacement DA31-00342A to the old part to ensure identical fittings, ports, and electrical connectors. Replace any O-rings or gaskets as recommended (lubricate O-rings lightly with food‑grade silicone lubricant if provided). 8) Install replacement: position the new part, secure screws/clips, reconnect tubing and electrical plugs, ensuring push-fit tubing seats fully and electrical connectors click in. Reinstall any interior panels or shelves you removed. 9) Restore water and power: turn the water supply back on, check for leaks at all connections. Plug the refrigerator back in or restore power. 10) Test thoroughly: dispense several cups of water to purge air and any debris. Check for leaks while dispensing and after a 10–15 minute soak period. Confirm dispenser operation and that ice maker (if water line shared) is functioning normally. 11) Final checks: if you installed a component related to the filter housing, replace the water filter if it was removed or is older than recommended. Monitor for 24–48 hours for any slow leaks or performance issues. Safety note: Always shut off power and water before working on the water system. If you are not comfortable working with plumbing or electrical connections, hire a qualified appliance technician. If you cannot positively confirm the part by model diagram or the label on your existing part, do not proceed—ordering the wrong part can damage fittings or cause leaks.

Common Symptoms

No water from dispenser, slow or intermittent flow, visible leak around dispenser/filter area, cracked plastic housing near dispenser, bad tasting or odorous water, or dispenser switch/electrical connector failure.

Common Causes

• Cracked or damaged dispenser/filter housing (physical breakage or stress)
• Worn or damaged O‑rings or push‑fit tubing fittings causing leaks or poor seal
• Mineral/clog buildup inside water paths or internal valve/fittings restricting flow
