E17 on display, refrigerator temperature may be too low (overcooling) or food freezing in fresh food section

Safety first: Unplug the refrigerator before accessing sensors or dampers.

Steps:

• Verify settings: Ensure the temperature setpoints are not set too low. Adjust to manufacturer-recommended levels and wait 24 hours.
• Check damper operation: Locate the air damper between freezer and fridge (often behind a cover in the fridge back wall). Listen for it opening/closing when temperature changes. If stuck open, cold air will flood the fridge.
• Inspect damper for ice: Remove the cover and check for ice blocking the damper. Defrost gently if needed.
• Sensor check: Test the refrigerator thermistor for proper resistance at known temperatures. Replace if readings are out of range.
• Control board: If sensor and damper are good but E17 persists, the control board may be misregulating cooling and require replacement.

Tip: Avoid placing highly perishable items directly in front of cold air vents.
