LG LFXS26973S Refrigerator Problems & Error Codes — Overview
The LG LFXS26973S is a French-door refrigerator with bottom freezer and in-door ice maker. The most common service calls involve ice maker fan faults (IF or F1 error codes) caused by frost accumulation in the ice room, followed by sensor and wiring issues. The ice maker fan circulates air in the ice compartment, and when ice or frost blocks the fan blade or the fan motor fails, the control throws a fault code and ice production stops.
Other frequent problems include the IS or 15 code (ice maker fan motor or sensor disconnection), recurring frost buildup from poor door seal, and temperature control complaints tied to airflow blockage. Most IF and F1 faults clear after manually defrosting the ice room and checking the fan motor and harness connections. If the code returns after defrost and reset, the fan motor or sensor usually needs replacement.
Most Common Problems on This Model
- IF or F1 error code and no ice production Ice or frost buildup physically blocks the ice maker fan blade, or the fan motor has failed and needs replacement after defrosting the ice room.
- IS or 15 error code The ice maker fan motor is not running or the icemaker sensor connector is loose, damaged, or disconnected from the harness.
- Recurring frost or ice in the ice maker compartment Worn or damaged door gasket allows warm air into the ice room, causing repeated frost accumulation and triggering fan fault codes.
- Ice maker fan runs but code does not clear Faulty ice-room sensor sends incorrect readings to the control board even when the fan operates normally, requiring sensor replacement.
- Code returns immediately after reset Broken or corroded wiring to the ice maker fan motor or sensor prevents the control from seeing proper fan operation.
- Ice maker stops working with no error code displayed Ice maker fan motor has failed silently or obstruction in the ice room airflow path stops air circulation without triggering a stored fault.
- Intermittent IF code after door is opened Loose wiring connector vibrates when the door closes and breaks the fan or sensor circuit, then reconnects when the door is moved again.
- Freezer or refrigerator temperatures fluctuate with ice maker fault Blocked airflow in the ice compartment or failed fan reduces overall air circulation and impacts temperature stability in adjacent zones.
Parts That Commonly Fail
| Part | Notes |
|---|---|
| Ice maker fan motor | Amazon | Fails from frost damage or bearing wear, stops blade rotation and triggers IF or F1 code. |
| Ice maker sensor (ice-room sensor) | Amazon | Reads temperature or fan status; when open, shorted, or disconnected it causes IS or 15 code. |
| Ice maker fan wiring harness and connectors | Amazon | Corrodes or loosens in the moist ice room environment, breaking the fan or sensor circuit. |
| Door gasket (refrigerator door) | Amazon | When torn or loose, allows humid air into the ice compartment and causes recurring frost buildup. |

When to Call a Pro
Call a technician if the IF, F1, IS, or 15 code returns after you have unplugged the unit for two minutes, manually defrosted the ice room, and confirmed the fan area is clear of ice and obstructions. Replacing the ice maker fan motor or sensor requires disassembly of the ice compartment, disconnecting the door wiring harness, and testing circuits with a multimeter. If you are not comfortable working with live 120V connections or removing interior panels, a qualified appliance tech can diagnose the fan motor, sensor, and wiring in one visit and install the correct replacement part. Recurring frost issues that involve door alignment or gasket replacement also benefit from professional adjustment to prevent future fan faults.
