Miele Refrigerator Error Code F144

F144 indicates that the freezer door was detected as open or not fully closed for a continuous period of 15 minutes. The code is logged internally by the appliance and is not necessarily shown as a visible alert on the display. It is a protective monitoring function designed to flag situations where the freezer compartment may have been exposed to warm air for an extended time.

Yes, a freezer door left open for 15 or more minutes allows warm air to enter the compartment, which can raise internal temperatures and compromise frozen food safety. Once the door is properly closed, the freezer will work to recover its set temperature. If the door was open for an extended period, check that food remains solidly frozen before assuming it is still safe to consume.

If the cause is simply a door left open or an obstruction, there is no repair cost involved. A replacement door gasket typically ranges from $30 to $80 depending on the specific Miele model. If the door switch requires replacement, parts and labor combined can range from $80 to $200. Diagnosis by a qualified technician is recommended if closing the door and checking for obstructions does not resolve the repeated logging of this code.

Start by firmly closing the freezer door and confirming there are no obstructions such as food packages or improperly seated drawers blocking it. Check the door gasket for damage or deformation that could prevent a proper seal. If frost has built up around the door frame, allow it to defrost or carefully remove the ice. If the door closes properly but the code keeps appearing, the door switch may need to be tested and potentially replaced.

Since F144 is an internal log entry rather than a displayed fault, simply closing the door and allowing the appliance to return to normal operating temperature is typically the appropriate resolution. A power reset may clear any associated alert state, but the underlying cause must be addressed first. If the door switch is faulty, the code will continue to be logged regardless of resets.
