Kenmore Refrigerator Error Codes

Kenmore Refrigerator Error Code Er CO

The Er CO error code on your Kenmore refrigerator is related to communication problems between two essential components: the main board (control board) and the display board (user interface). This error can disrupt the operation of various functions within your refrigerator.

  1. Loose Wiring Connections: Over time, wiring connections can become loose or disconnected due to vibrations or general wear and tear.
  2. Faulty Control Boards: A malfunctioning main board or display board can lead to communication errors. These components can fail for various reasons, including electrical surges or manufacturing defects.

Before calling a professional technician, there are a few steps you can take to troubleshoot the Er CO error:

  1. Check Wiring Connections: Inspect the wiring connections between the main board and the display board. Make sure they are securely connected. If you find any loose or disconnected wires, reattach them.
  2. Reset the Refrigerator: Sometimes, a simple reset can resolve the communication error. Unplug the refrigerator for a few minutes and then plug it back in. This action can clear minor glitches.

If the Er CO error persists after checking wiring connections and attempting a reset, or if you suspect a faulty control board, it’s best to seek professional assistance. Communication errors between critical components are often best addressed by experienced technicians who can diagnose the specific issue and replace the necessary parts. Trying to replace control boards without the right skills and tools can be complex and may result in further damage.
