Miele Refrigerator Error Code F145

F145 indicates that the freezer door was detected as open for a continuous period of 30 minutes. This is an internal diagnostic code that may not be prominently displayed to the user but is logged by the control board. It serves as a flag for technicians to investigate door seal integrity, door switch function, or actual user habits. The first step is to confirm the freezer door is fully closed.

A reset may clear the stored code temporarily, but if the underlying cause, such as a faulty door switch or a damaged gasket, has not been addressed, the condition will likely recur and the code will be logged again. It is best to diagnose and resolve the root cause before relying on a reset to clear the fault.

If the fix is simply closing the door or removing an obstruction, there is no parts cost involved. Replacing a door gasket typically ranges from $50 to $150 in parts depending on the model, plus labor if a technician is needed. A faulty door switch or sensor repair can range from $75 to $200 or more depending on parts availability and labor rates in your area.

Begin by closing the freezer door completely and checking that no food items or frost buildup are blocking it from seating properly. Inspect the door gasket for damage and verify the door is properly aligned on its hinges. If the error persists despite the door being closed, the door switch or magnetic sensor may need to be tested and potentially replaced by a qualified technician.

A freezer door open for 30 minutes or more allows warm air to enter, which can raise internal temperatures and put frozen food at risk if the condition is prolonged or recurring. Address the cause promptly to prevent food spoilage and to avoid putting unnecessary strain on the compressor and cooling system over time.
