LG LFX28978ST/04 refrigerator Parts

To turn off the ice maker on your LG LFX28978ST, set the ice maker’s On/Off switch to OFF (O). If you leave it off for more than a few hours, we recommend emptying the ice bin to prevent melting and leaks; see the LFX28978ST owner's manual.

Where the switch is and what “OFF” means

On this LG bottom-mount refrigerator, the ice maker has a physical power switch marked I (On) and O (Off). When the switch is set to OFF (O), ice production stops.

• Open the freezer and access the ice maker area.
• Locate the ice maker switch labeled I / O.
• Move the switch to OFF (O).
• If the ice bin is full, remove and empty it if the ice maker will stay off.
• Keep the ice compartment door closed tightly to avoid temperature issues.

Important tips to avoid leaks or ice issues

If the ice maker is off for an extended period, the ice compartment can warm up toward refrigerator temperature. That can cause stored ice to melt and drip.

• Empty the ice bin if the ice maker will be off more than a few hours.
• Do not store cans or other items in the ice bin; they can damage the ice maker.
• Avoid touching the ice-detecting sensor when removing or reinstalling the bin.
• Use caution around the ice bin blade area; edges can be sharp.

Quick reference table

Task	What to do	Why
Stop making ice	Switch to OFF (O)	Prevents new ice production
Ice maker off for hours	Empty the ice bin	Helps prevent melting and leaks
Low ice production later	Switch back to ON (I) and wait 24 hours	Normal recovery time

Why it matters

Turning the ice maker off the right way prevents water leaks, reduces mess in the freezer, and avoids damage caused by melted ice sitting in the bin.

For the LG LFX28978ST bottom-mount refrigerator, the key dimensions are 35 3/4 in. wide x 35 3/8 in. deep x 69 3/4 in. high, with 47 5/8 in. depth with the door open. For the full spec list and installation clearances, use the LFX28978ST owner's manual.

Key dimensions (from the manual)

Measurement	Dimension
Width	35 3/4 in.
Depth (cabinet)	35 3/8 in.
Height	69 3/4 in.
Depth with door open	47 5/8 in.

Installation clearance and space planning

Even when the cabinet fits, we plan for door swing, airflow, and service access.

• Allow at least 24 in. of open space in front so the doors can open fully.
• Leave room behind the unit for the water line and power cord.
• Make sure the refrigerator sits on a solid, level floor to reduce vibration and noise.
• If doors do not self-close smoothly, adjust the leveling legs so the front is slightly higher.

Why it matters

Correct dimensions and clearances prevent poor cooling performance, higher energy use, and door alignment issues. They also help avoid pinched water lines that can cause dispenser or ice maker problems.
