LG Refrigerator: intermittent ice maker operation
What is this symptom?
Experiencing intermittent ice maker operation in your LG refrigerator? This common issue may arise due to a clogged water supply, suboptimal freezer temperature, or a frozen ice maker assembly. Understanding these causes can help you troubleshoot effectively.
Possible Causes
Clogged or restricted water supply (filter/line)
How to Identify: Ice production pauses; weak or intermittent water dispenser flow; water line may be frozen or kinked.
Part: Water filter / water line / water inlet valve
Freezer temperature not optimal
How to Identify: Freezer warmer than optimal can slow/stop ice making; checking with independent thermometer helps.
Part: Freezer thermostat / temperature control
Ice maker assembly frozen or blocked
How to Identify: Visible frost or ice buildup around fill tube or tray; ice maker stops until thawed.
Part: Ice maker fill tube / ice mold
Faulty ice maker switch or control arm
How to Identify: Switch accidentally off or control arm/sensor stuck leading to intermittent operation; iFixit notes this.
Part: Ice maker power switch / control arm/sensor
