What the Error Code Means
Error code CO generally means the refrigerator detected a communication condition and paused to report it.
It points to a communication status rather than a confirmed single failure.
Common Symptoms You May Notice
- The display shows CO and the unit may beep.
- Cooling may continue but the alert remains on the display.
- Some controls may feel unresponsive until the alert clears.
Most Common Causes (From Least to Most Serious)
- Temporary control panel glitch: A brief interruption can cause a communication alert even when cooling is normal.
- Power interruption or reset: A short power interruption can trigger a status message on the display.
- Communication status is outside the expected range: In some cases the refrigerator reports a communication condition to protect normal operation.
Safe Things You Can Check Yourself
- Press any key or reset the alert to clear the display.
- Confirm the power cord is fully seated in the outlet.
- Power cycle the refrigerator: unplug it for one minute, then plug it back in.
If at any point this feels unsafe or unclear, stop and contact a professional.
When to Stop and Call for Service
- The CO code returns repeatedly without a known interruption.
- Controls remain unresponsive or cooling does not return to normal.
- You notice burning smells, sparking, or repeated shutdowns.
Typical Repair Cost Range
$0-$200 is typical for diagnosis if communication-related alerts persist, depending on the cause and parts involved.
Costs vary by region, model, and provider. Request an estimate before approving any repair.
