LG LHFS28XBS Service Manual PDF Key Features and Content
Strategic Troubleshooting Guide
| If you are experiencing… | Go to Section… | What to do |
| No Ice / Slow Ice | 91–97 (pg 91) | Check the operation of both the in-door and freezer ice makers. |
| “Er IF” or “Er FF” Codes | 25–68 (pg 25) | These are fan-related codes; use the PCB Picture (pg 23) to find the test points. |
| Loud Grinding/Chirping | 11 (pg 11) | Focus on the evaporator fan motor. These often ice over if the defrost fails. |
| Water under drawers | 18 (pg 18) | Remove the vegetable drawer to check for a clogged defrost drain. |
| Compressor hums/clicks | 80 (pg 80) | Follow the flowcharts for inverter/linear compressor diagnosis. |
Key Technical Highlights
- Dual Ice Systems (Sections 91–97): Since this model has two ice makers, pay close attention to which one is failing. Page 91 handles the dispenser/in-door logic, while Page 95 focuses on the tray-style maker in the bottom freezer.
- The “Cap Duct Motor” (Section 13): This is a common point of failure for ice dispensers. If the small door that lets ice out doesn’t open or close properly, moisture gets into the ice compartment and freezes everything into a solid block.
-
Component Testing (Section 73–79): Before replacing an expensive board, check the resistance values of the sensors and heaters here. A faulty defrost heater can often mimic a broken compressor.
PCB & Circuitry (Sections 20–24)
If the refrigerator is completely “dead” or the display is acting up:
- Check the Main PWB (Page 13) for a blown fuse.
-
Use the PCB Picture (Page 23) to locate the Test Button. Pressing this button once or twice can force the fridge into a “Service Mode” to test the compressor and fans immediately.
Pro-Tip: Door Alignment (Section 11)
If you notice frost building up or the fridge is running constantly, check Page 11. French door models are very sensitive to being level. If the doors are even slightly misaligned, the center gasket (mullion) won’t seal, letting warm air in.
