Refrigerator problems and solutions FAQs: Diagnostic and Troubleshooting Guide Q&A

If the display won’t light up, this could be caused by several issues, including the refrigerator not being switched on, an unplugged power cord, a wall outlet without power, or melted internal safety fuses. Here are the steps to solve the problem:

  • Switch on the refrigerator.
  • Do not use an extension block! Plug the power cord directly into a wall outlet.
  • Check and activate the main power fuse.
  • Unplug the refrigerator. Use another working appliance to check the wall outlet, or plug the refrigerator into another working outlet.
  • Measure for 110/220 VAC at the wall outlet. Check the power assembly and the internal safety fuse.
  • Check the display PCB buttons.
  • Check the harness on the main PCB.

If you’re observing water inside or around the refrigerator, this could be caused by several issues, including melted water due to an unwanted defrost, a clogged drain pipe, an overflowing drip tray, a bad connection at the bottom of the door(s), a bad connection at the water tap, a bad connection to the external filter, a bad connection at the water inlet valve, a not completely closed ice dispenser valve, too high external water pressure, or abnormal water supply to the ice maker. Here are the steps to solve the problem:

  • Check if the refrigerator is turned on, the compressor is running, and the cooling and freezing temperatures are normal. If this is not the case, the cooling process is disturbed.
  • Check inside the refrigerator to see if the drain is clogged (water at the bottom).
  • Check at the dispenser if the water is dripping just after dispensing or continuously. After dispensing is normal, continuous dripping could increase the pressure on the water line and reduce the water supply, if necessary, by turning the water tap. Power off the refrigerator and check the water inlet valve to see if water is still supplied.
  • Check the water hoses at the doors for proper connection. Warning: Pulling the hoses without removing the retainer will damage the hose.
  • Check the water hose connecting the tap, the external filter, and the water inlet valve at the back. Check the water level of the drip tray. Note: This tray collects the water from the defrost cycle that normally evaporates due to the heat of the condenser.
  • Check the ice dispenser valve.
  • Check the filling of the ice-maker tray.
  • Check the refrigerant level. A heavy repair could be necessary.
