Miele Freezer Error Code F145

F145 indicates that the freezer door was detected as open or not fully closed for a continuous period of 30 minutes. This code is recorded internally by the appliance's control system and is not shown on the user display. It surfaces during a service-level diagnostic scan. The first step is to ensure the door is fully closed and the gasket is sealing properly.

It depends on how long the door was open and the ambient temperature at the time. A 30-minute open-door event will cause the internal temperature to rise, but if the freezer was well-stocked and the door was closed promptly after the alert was discovered, most frozen items are likely still safe. Check that items remain solidly frozen throughout and discard anything that shows signs of thawing or ice crystal loss.

Cost depends on the root cause. If the fix is a door gasket replacement, parts and labor typically range from around $100 to $250 depending on the model and your location. A faulty door switch is generally less expensive in parts but still requires a service call, putting total costs in a similar range. Hinge adjustment or leveling is usually a minor labor charge. A service diagnostic visit alone can run $75 to $150 before any parts are involved.

Start by confirming the door closes completely and latches without resistance. Inspect the door gasket around its entire perimeter for any damage, flattening, or gaps. Remove any items inside the freezer that may be obstructing full door closure. If the door and gasket check out, have a technician test the door switch, as a faulty sensor can generate this code even when the door is physically shut.

Since F145 is an internal diagnostic code not displayed to the user, a simple power reset may clear the logged entry, but it will not address the underlying cause. If the door switch, gasket, or alignment issue is not corrected, the condition will recur and the code will be logged again during the next 30-minute open-door event. Resolving the root cause is the correct approach before clearing any stored fault codes.
