Fault codes for refrigerators

The decoding of the values ​​on the display can be found in the operating instructions. First of all, we'll tell you what to do when the code appeared for the first time:

  • Disconnect the refrigerator from the mains.
  • Wait for 10-15 minutes.
  • Try restarting.

If the characters have not disappeared from the screen, you need to deal with decoding and eliminating the breakdown. Consider the value of errors for each brand.
