LG LMXS28626D/02 refrigerator Parts

Cooling performance problems are the most common issue we see reported on LG refrigerators like model LMXS28626D; symptoms include the refrigerator or freezer running too warm, temperature swings, and poor airflow. Many “cooling problems” are caused by blocked vents, frequent door openings, or a door that is not sealing correctly, as outlined in the LMXS28626D owner's manual.

Most common symptoms customers notice

• Fresh food section feels warm while the freezer seems closer to normal
• Food spoils faster or milk goes bad early
• Ice production slows down or stops
• Frost buildup or restricted airflow in the freezer area
• Longer run times (unit seems to run a lot)

Quick checks that fix many cooling complaints

We recommend these steps first because they match the most common causes in the troubleshooting guidance:

• Give a new installation time; it can take up to 24 hours to reach set temperatures
• Reduce long or frequent door openings (warm, humid air raises temps)
• Make sure packages are not blocking air vents; rearrange items to restore airflow
• Confirm doors close fully and consistently (no “pop open”)
• Avoid loading hot food; let it cool to room temperature first

What to check based on the symptom

Symptom	Most likely cause	What we do next
Both sections too warm	Doors opened often, hot room, hot food load	Improve usage conditions; recheck temps after 24 hours
Fridge warm, freezer colder	Air vents blocked	Clear vents and avoid overpacking
Ice and water issues along with warm temps	Water/ice system affected by temps or airflow	Address cooling first; then check dispenser/ice operation

Parts that are commonly involved when a repair is needed

If the quick checks do not resolve the issue, these model-related parts are often involved in cooling or airflow complaints:

• Refrigerator condenser fan motor EAU63923602 (moves air across the condenser)
• Refrigerator temperature sensor 6500JB2002X (reports temperature to the control)
• Refrigerator defrost heater MEE63545708 (helps prevent frost that can block airflow)

Why it matters

Stable temperatures protect food quality and help the compressor and fans run efficiently. Simple airflow and door-seal issues can mimic major failures, so checking vents and door closing first saves time and prevents unnecessary parts replacement.

On LG model LMXS28626D, ice building up on the freezer floor is most often caused by a clogged or frozen defrost drain, so defrost water cannot flow to the drain pan and instead refreezes at the bottom. Door-opening moisture can add to the problem; use the LMXS28626D owner's manual for model-specific care and operating guidance.

Most common causes

• Defrost drain hole or drain tube is blocked by ice, food debris, or sludge
• Drain tube is partially restricted, so water drains too slowly and refreezes
• Door left open or opened frequently, letting humid air in (creates frost that later melts and refreezes)
• Door not sealing well, increasing moisture and frost buildup
• Freezer overloaded, blocking airflow and promoting uneven frost patterns

What we recommend (safe DIY steps)

1. Manually defrost the freezer: move food to a cooler, unplug the refrigerator, and leave the freezer door open until the ice sheet melts.
2. Clear the drain path: once melted, locate the drain opening and flush it with warm water (a turkey baster works well).
3. Check the door seal: close a dollar bill in the gasket; if it slips out easily, the seal may be leaking.
4. Reduce moisture load: limit long door openings and make sure containers are covered.

Helpful part to consider

If the drain tube is cracked, missing, or won’t clear, replacing the drain component can restore proper drainage. For this model, see the refrigerator drain tube 5251JA3003D.

Quick symptom-to-cause guide

What you see	Most likely cause	What to do first
Thick ice sheet on freezer floor	Frozen/blocked defrost drain	Defrost, then flush drain with warm water
Frost on packages and walls	Door opened often, humid air entering	Reduce door-open time, verify gasket seal
Water/ice returns in a few days	Drain still restricted or refreezing	Re-flush drain; confirm door closes fully

Why it matters

When the defrost drain can’t move water out, meltwater refreezes into a growing ice slab. Over time, this can lead to puddles, poor airflow, temperature swings, and more frequent frost issues.

On the LG LMXS28626D, leaking from the bottom is usually caused by a defrost drain that is clogged or frozen, or by a water supply connection issue (especially if the ice maker or dispenser is used). Clearing the drain path and checking the water line and valve typically stops the leak.

Most common causes (and what to check first)

• Clogged defrost drain: Meltwater cannot flow to the drain pan, so it overflows and runs to the floor.
• Frozen drain tube: Ice blocks the drain and forces water out of the air ducts or down the cabinet.
• Water line connection or pressure issue: The manual calls out water hammer and incorrect conditions as common causes of leakage.
• Leaking inlet valve: A valve that seeps can drip and track down to the bottom.
• Ice maker left ON before water is connected: This can contribute to water-related issues during setup.

Quick troubleshooting steps (safe DIY)

1. Unplug the refrigerator and remove food from the area you are working in.
2. Look for ice or debris at the back bottom inside the fresh food section (typical defrost drain location). Melt any visible ice with warm water.
3. Flush the drain with warm water using a turkey baster or squeeze bottle until it flows freely.
4. Inspect the water supply line behind the unit for kinks, loose fittings, or rubbing.
5. Verify water pressure: LG specifies 20 to 120 psi for models with a water filter; low or unstable pressure (water hammer) can lead to leaks.

Parts that commonly fix bottom leaks on this model

If you confirm the leak is coming from the water system (not the defrost drain), these model-matched parts are common fixes:

Symptom you see	Likely area	Model-matched part to consider
Drips behind fridge, puddle near wall	Water supply/valve	LG refrigerator water inlet valve AJU72992601
Water appears after defrost cycle, then stops	Defrost drain path	Refrigerator drain tube 5251JA3003D

Why it matters

A bottom leak is not just a nuisance; it can damage flooring and can also point to airflow icing problems that reduce cooling performance. Fixing the drain path or water supply leak early helps the LMXS28626D cool consistently and prevents repeat puddles.
