LG LRTLS2403S: Evaporator Fan Motor Failure in Memorial, TX
📞 Call (346) 512-3688🔧 Performed by Serhii T.
The Problem
- •Fresh food section holding 50-56°F instead of the target 37°F
- •Freezer compartment reading approximately 30°F, far above safe freezing temperature
- •No airflow detectable from evaporator fan vents inside the refrigerator
- •Food in the fresh food section beginning to spoil despite the compressor running
🔍 Diagnosis
When I arrived at the home in the 77077 zip code, the customer told me the fresh food section of his LG LRTLS2403S was not getting cold. I pulled out my thermometer and confirmed the fresh food section was sitting between 50 and 56°F. I then checked the freezer and found it at around 30°F. Neither compartment was at a safe operating temperature. The compressor was running, which told me the sealed system using R-600a refrigerant was likely intact. My first suspicion went straight to the evaporator fan motor. This is a well-documented failure pattern on LG French door and multi-door units. I removed the rear interior panel in the freezer section to access the evaporator area. The fan blade was not spinning at all. I disconnected the fan motor connector and tested voltage at the harness: 12V DC was present, confirming the control board was sending a signal. Then I tested the motor windings directly with a multimeter and got an open circuit reading, indicating a burned-out motor coil. The motor itself had failed internally. Without the evaporator fan pushing air across the evaporator coils and circulating it through both compartments, neither the freezer nor the fresh food section could maintain temperature, even though the evaporator coils were cold and the compressor was running normally.
🔧 The Repair
- ✓Step 1: Confirmed temperatures with a calibrated digital thermometer: fresh food section at 54°F, freezer at 31°F. Compressor was running and condenser was warm to the touch, ruling out a sealed system fault.
- ✓Step 2: Removed all food and shelving from the freezer compartment to access the rear evaporator panel.
- ✓Step 3: Peeled back the protective foam insulation layer covering the evaporator fan assembly mounted on the large plastic evaporator cover panel, known on this model as the evaporator grille.
- ✓Step 4: Removed the four screws securing the large black fan motor bracket to the evaporator grille panel.
- ✓Step 5: Removed the two screws holding the fan motor cover in place and separated the cover to expose the evaporator fan motor.
- ✓Step 6: Disconnected the fan motor wiring harness, confirmed 12V DC was present at the connector with a multimeter, then tested motor windings and found an open circuit confirming internal motor failure.
- ✓Step 7: Installed the new evaporator fan motor, secured the fan motor cover with two screws, reinstalled the black motor bracket with four screws, replaced the foam insulation layer, and reassembled the evaporator grille panel.
- ✓Step 8: Powered the unit on and confirmed the new fan motor started immediately. After a 2-hour runtime, fresh food section measured 38°F and freezer measured 4°F, both within normal operating range.
✓ Result
After two hours of runtime with the new evaporator fan motor installed, the freezer settled at 4°F and the fresh food section reached 38°F. Both compartments were back to normal operating temperatures. The customer in Memorial was relieved because he had a full load of groceries that were borderline on safety. He confirmed the food in the fresh food section was still salvageable. I gave a 90-day labor warranty on the repair. Based on this motor type and the quality of the replacement part, he should get three to four years of reliable service before any fan-related issue would be expected again.
💡 Technician Notes
LG multi-door refrigerators, including the LRTLS2403S, have a known tendency for evaporator fan motor failures. The motors in these units run in cold, humid conditions and the coil windings degrade over time. One early warning sign specific to this failure: you will notice the freezer temperature slowly drifting up over several days before the fresh food section becomes noticeably warm. Many owners assume it is a door seal problem at first. It is not. If both compartments are warming at the same time and the compressor is running, the evaporator fan is the first thing to check on an LG. To extend fan motor life, keep the freezer drawer seals clean so excess moisture does not accumulate around the fan assembly. If you hear the compressor running but feel no airflow from the vents inside the fresh food section, do not wait more than 24 hours to call. Food safety becomes a real concern quickly when the fresh food section climbs above 45°F.
Frequently Asked Questions
Why is my LG refrigerator not cooling in the fresh food section but the compressor is still running?
On LG French door and multi-door models like the LRTLS2403S, this usually points to a failed evaporator fan motor. The compressor keeps running because the sealed system is fine, but without the fan circulating cold air, neither compartment cools properly. A technician can confirm this within minutes by checking fan voltage and motor winding resistance.
How much does it cost to replace an evaporator fan motor on an LG refrigerator in Houston?
For an LG multi-door model in the Houston area, evaporator fan motor replacement typically runs between $180 and $320 total, including parts and labor. The repair itself takes one to two hours on models like the LRTLS2403S. Same-day service is usually available since the part is commonly stocked by local LG repair specialists.
What happens if I ignore a failing evaporator fan motor in my LG refrigerator?
If you leave the evaporator fan failed, your LG will continue to run the compressor without circulating cold air. Temperatures in the fresh food section will climb to 50°F or above within 24 to 48 hours. Dairy, meat, and leftovers become unsafe quickly at those temperatures. The longer you wait, the higher your food loss cost compared to the repair cost.
Is it worth repairing an LG LRTLS2403S evaporator fan motor or should I replace the refrigerator?
An evaporator fan motor failure is one of the most cost-effective repairs on an LG. The sealed system and compressor are unaffected, meaning the most expensive components are intact. Unless your unit is over 12 years old or has a history of sealed system repairs, replacing the fan motor makes clear financial sense and extends the appliance life by several years.
Why does the evaporator fan motor on LG refrigerators fail so often compared to other brands?
LG evaporator fan motors run continuously in cold, high-humidity environments inside the freezer section. Over time, the motor windings absorb moisture and corrode internally, leading to an open circuit and complete motor failure. LG units are not unique in this regard, but their specific motor design and placement make them somewhat more prone to this failure pattern than some competing brands.
