Precautionary measures
• Verify the refrigerator is plugged securely into a grounded 115V outlet (standard USA electrical outlet)
• Check that both the refrigerator and freezer doors are closing completely and sealing properly
• Ensure the refrigerator is level by checking with a bubble level tool - adjust the front feet if needed
• Confirm temperature settings are correct (typically 35-38°F for fresh food, 0°F for freezer)
• Clear any blocked air vents inside the refrigerator or freezer compartments
• Allow the refrigerator to stabilize for 30 minutes after any recent power interruption
• Perform a hard reset by unplugging the unit from the wall outlet for 60 seconds, then plugging it back in
• Alternatively, turn off the home circuit breaker supplying power to the refrigerator for 60 seconds, then restore power
• Wait 5-10 minutes after reset to allow the control system to reinitialize
• If the error code 28 persists after these checks, contact a professional appliance repair technician for diagnostic testing and component replacement
