Why does my LG freezer keep icing up at the bottom?
On LG model LMXC23796S, ice collecting on the freezer floor is most often caused by a clogged defrost drain. When the drain can’t carry defrost water to the drain pan, water refreezes at the bottom and builds into a sheet of ice. See the defrost and cleaning guidance in the LMXC23796S owner’s manual.
What to check first (quick, safe steps)
- Unplug the refrigerator before working inside the freezer.
- Remove the freezer drawer/baskets so you can see the freezer floor.
- Look for a solid ice slab at the bottom (classic sign of a drain issue).
- Check for food packages blocking air vents; poor airflow can increase frost.
- Confirm the freezer is closing fully and the gasket is sealing.
Clear the drain and stop the ice from coming back
- Manually defrost the freezer floor area (door open, towels down). Avoid sharp tools that can puncture the liner.
- Once the ice softens, locate the drain opening (typically near the rear floor area) and clear visible debris.
- Flush the drain with warm water (a turkey baster works well) until it flows freely.
- If the drain keeps freezing or backing up, inspect the drain path and related tubing; on this model, the drain routing to the pan is part of the refrigerator drain tube assembly 5251JA3004E.
Common causes and what they look like
| What you see | Most likely cause | What usually fixes it |
|---|---|---|
| Ice sheet only on freezer floor | Defrost drain clogged | Defrost and clear/flush drain |
| Frost on packages and walls too | Door not sealing, frequent openings | Check gasket, reduce door-open time |
| Water then ice after cleaning | Drain tube restricted or icing | Inspect/replace drain tube assembly |
Why it matters
A blocked drain can force water to refreeze repeatedly, reducing freezer space, making drawers hard to open, and increasing run time. Clearing the drain restores normal defrost water flow and helps prevent repeat icing.

What is a bottom mount refrigerator?
A bottom-mount refrigerator puts the freezer section below the fresh-food section, so the items you use most in the refrigerator stay at eye level. On LG model LMXC23796S, the freezer is a pull-out drawer system with multiple storage levels for better organization.
How the LMXC23796S bottom-mount layout is arranged
Based on the model’s design described in the LMXC23796S owner’s manual, you’ll typically have:
- Fresh-food compartment on top (French door refrigerator section)
- Bottom freezer that pulls out like a drawer
- Multiple freezer storage tiers (including pullout drawer storage and a lower bin area)
- Dedicated zones such as crispers and a CustomChill drawer for flexible-temperature storage
Bottom mount vs. top freezer: quick comparison
| Feature | Bottom mount (like LMXC23796S) | Top freezer |
|---|---|---|
| Fresh-food access | Easier (eye level) | More bending for fresh food |
| Freezer access | More bending | Easier (higher) |
| Freezer organization | Often multi-tier pull-out system | Often shelves in a swing door |
| Best for | Fresh-food-first households | Freezer-first households |
Why it matters
Most people open the refrigerator section far more than the freezer. A bottom-mount design reduces bending for everyday items and makes it easier to see what’s in the fresh-food compartment, which can help reduce food waste.
Helpful setup tip
After installation or a move, allow cooling time before loading food. The LMXC23796S owner’s manual notes that it can take 2 to 3 hours before putting food in, and up to 24 hours for compartments to reach target temperatures.

Are LG stainless steel refrigerators magnetic?
LG stainless steel refrigerators can be magnetic or not depending on the specific door material and finish; for LG model LMXC23796S, the owner’s manual does not specify whether the exterior panels are magnet-friendly, so the most accurate way to confirm is a simple magnet test on the doors and freezer drawer using normal household magnets.
What we can confirm for LMXC23796S
The LMXC23796S owner’s manual covers operation, cleaning, and features, but it does not state whether the stainless exterior is magnetic. Because manufacturers may use different stainless alloys or layered door panels within a model family, magnet behavior is best verified on your unit.
Quick magnet test (recommended)
Test a few spots with a typical refrigerator magnet and a stronger souvenir-style magnet:
- Upper left door center
- Upper right door center
- Around the dispenser area (avoid plastic trim)
- Freezer drawer front
- Near door edges (often backed by structure)
If a magnet barely holds or slides, try a stronger magnet or a different location.
What surfaces usually are not magnetic
Even on stainless-look refrigerators, these areas typically will not hold magnets:
- Plastic trim and handle pieces
- Dispenser bezels and control panel overlays
- Decorative stainless-look films over non-steel panels
Why it matters
Knowing whether magnets will stick helps you avoid scratches and frustration. If your LMXC23796S doors are not magnetic, you can use alternatives like removable adhesive hooks (rated for appliances) or place magnets on any painted steel side panel that is accessible.
Typical magnet behavior by material (general guide)
| Exterior surface type | Magnet behavior | Common example |
|---|---|---|
| Painted steel | Strong hold | Side panels on many refrigerators |
| Magnetic stainless/steel-backed panel | Moderate to strong hold | Some door skins |
| Non-magnetic stainless or layered panel | Weak or none | Some premium stainless finishes |
