Seeing a ‘CO’ error code on your Whirlpool refrigerator’s display can be a real head-scratcher, but don’t fret! This code primarily signals a communication breakdown between your appliance’s main control board and its display control. Essentially, they’re having trouble talking to each other, which can prevent your fridge from operating correctly. Good news is, many common causes are manageable and you might be able to resolve this issue yourself.
What Triggers a Whirlpool CO Error?
Understanding the root causes of a ‘CO’ error is the first step toward a successful fix. This particular error often points to issues similar to those indicated by E6/F6 codes, all centering around inter-board communication. Here are the typical reasons your Whirlpool refrigerator might display a ‘CO’ code:
- Loose, corroded, or damaged wire harness connections between the main control board and the display control board.
- A faulty display control board that is unable to send or receive signals correctly.
- A malfunctioning main control board, which is the brain of your refrigerator, failing to communicate with the display.
- Rarely, a power surge or unstable power supply can temporarily disrupt communication, leading to the error.

Diagnosing and Fixing the CO Communication Error
Addressing the ‘CO’ error on your Whirlpool refrigerator involves a systematic approach, primarily focusing on the wiring and the control boards themselves. Follow these steps to diagnose and potentially resolve the issue:
- Safety First: Unplug the Appliance
Always begin by unplugging your Whirlpool refrigerator from the electrical outlet. This is a crucial safety step to prevent electrical shock and damage to components. - Locate Control Boards
Identify the main control board (typically found at the back of the refrigerator, behind an access panel) and the display control board (usually integrated into the dispenser panel on the door or inside the fresh food compartment). - Inspect Wire Harness Connections
Carefully disconnect and then firmly reconnect all wire harness connections linking the main control board to the display control. Look closely for any signs of damage, fraying, cuts, or corrosion on the wires and their connectors. Repair or replace any damaged harnesses if observed. - Test for Resolution
After ensuring all connections are secure, plug the refrigerator back into the wall outlet. Observe if the ‘CO’ error code has cleared from the display. If it has, a loose connection was likely the problem. - Isolate the Faulty Board (If Error Persists)
If the error returns, one of the control boards is likely at fault. Since both boards are involved in the communication, it can be challenging to pinpoint the exact faulty component without specialized diagnostic tools. Often, a process of elimination is employed. - Consider Replacing the Display Control Board
Many technicians start by replacing the display control board, as it can be a common point of failure for display-related communication errors and is sometimes more accessible to replace than the main board. - Replace the Main Control Board
If replacing the display board does not resolve the ‘CO’ error, the main control board is the next logical component to replace. This board oversees all major refrigerator functions and its failure can certainly disrupt communication with the display.
