  • Faulty Water Inlet Valve: A malfunctioning valve restricts water supply.
  • Water Filter Issues: A clogged filter reduces water pressure.

Other Potential Problems

  • Error Codes: LG fridges often display error codes. Consult your user manual or LG’s website for code meanings.
  • Unusual Noises: Grinding or clicking sounds may indicate a problem with a fan motor or compressor.
  • Water Leaks: Leaks can come from a blocked defrost drain or damaged water lines.

Troubleshooting and Repair Tips

Before calling a technician, try these simple fixes:

  • Clean Condenser Coils: Unplug the fridge and use a vacuum cleaner or brush to remove dust.
  • Check Vents: Make sure air vents inside the fridge aren’t blocked by food items.
  • Reset the Fridge: Unplug it for a few minutes and then plug it back in.
  • Replace the Water Filter: This is a routine maintenance task that improves water flow and quality.

If these steps don’t resolve the issue, it’s best to contact a qualified appliance repair technician or LG customer service.
