Quick answer

- Applies to
- LG Refrigerator
- LG refrigerator codes · Refrigerator · 2010s onward
- Type of code
- Fault
- Urgency: Needs attention soon
- First safe check
- Open the ice maker area on a side-by-side or French door model and look for a blade that is stationary or locked in ice.
What IF means on this model
The fan inside the ice maker is not running, and frost or ice around it is the usual cause. The whole ice circuit stops when it does, because the ice maker cannot cool its own area without moving that air.
Symptoms you will notice
- Code appears on a model with an internal ice maker
- Ice maker runs but produces little or nothing
- Frost around the ice maker where there should be none
- Ice clumps together in the bucket
Common causes
The code tells you what the control detected, not which part failed. These are the causes we see most often, roughly in order of likelihood:
- Fan motor failed
- Frost or ice frozen against the fan blade
- A defrost fault leaving ice in the ice maker area
- Connector or harness fault behind the rear cover
- Drain fault letting water refreeze in the ice maker area
What you can safely check
These are homeowner-level checks. None of them need you to open a live electrical compartment or work on gas.
- Open the ice maker area on a side-by-side or French door model and look for a blade that is stationary or locked in ice.
- Check for a defrost or drain code that came before this one, since that is often the real cause.
- Listen for the fan running when the compressor starts.
Do not do these
- ×Do not pour warm water over a frozen ice maker fan, because the melt water refreezes in the same place and makes the jam worse.
When to call a technician
Book a technician, do not keep resetting it
This fault will not clear on its own. Every power cycle gives the control one more failed attempt, and repeated attempts are what turn a cheap part replacement into a seized or contaminated system.
- If the appliance has stopped mid-cycle, is making a noise you have not heard before, or smells burnt, stop reading here and call. Those are symptoms of something the fault code does not describe well enough.
Technician work. Confirm the drain and defrost are healthy first, because that is often the cheaper and more correct repair.
What it costs to fix
Parts
Ice maker fan $40 to $110. Ice maker module $60 to $180. Defrost heater $30 to $90.
Labor
Two to three hours on a model with a rear cover.
DIY or technician
Technician work. Confirm the drain and defrost are healthy first, because that is often the cheaper and more correct repair.
