Important Tips for Miele Models

Miele official troubleshooting lists reduced cooling as a specific issue and suggests ensuring proper ventilation openings and space per installation guidelines.

Possible Causes

Blocked airflow or obstructed vents inside fridge

How to Identify: Warm spots in fridge, freezer cold but fridge warm, vents blocked by food or frost buildup.

Part: Internal air vents/air channels

Dirty condenser coils reducing heat dissipation

How to Identify: Back or bottom of unit feels excessive heat, fridge runs constantly without reaching set temp.

Part: Condenser coils

Evaporator fan motor failure

How to Identify: No cold air movement, fridge warm though compressor runs, unusual fan noise.

Part: Evaporator fan motor

Door gasket seal failure allowing warm air entry

How to Identify: Cold air leaks when door closed, dollarâ€‘bill test slides out easily, visible seal damage.

Part: Door gasket/seal

Defrost system failure causing frost block on evaporator coils

How to Identify: Frost/ice buildup on coils or rear panels preventing airflow, water inside after defrost cycle.

Part: Defrost heater/thermostat system

Air damper or blocked air channel between freezer and fridge

How to Identify: Freezer stays cold while fresh food compartment warms, air damper does not open/move.

Part: Air damper assembly/air channel

Compressor or start relay/capacitor problems

How to Identify: Compressor silent or runs briefly, fridge fails to cool at all, rattling start relay.

Part: Compressor/start relay/start capacitor

DIY Solutions

Clean condenser coils

Moderate 30â€“60 minutes

Tools Needed: vacuum with brush attachment, coil cleaning brush

Unplug the fridge.
Access and locate condenser coils (back or bottom).
Use vacuum brush to clean debris and dust off coils.
Reconnect power and monitor cooling performance.

⚠️ Safety First: Unplug before working near electrical components.

Clear and ensure internal airflow

Easy 10â€“15 minutes

Tools Needed: none

Remove or rearrange food blocking internal vents.
Ensure at least 1â€“2 inches of clearance around items for airflow.
Check frost formation around vents and manually defrost if present.

Clean or replace door gasket

Easy 15â€“30 minutes

Tools Needed: warm soapy water, soft cloth

Inspect gasket for damage.
Clean gasket with warm soapy water to remove dirt.
Perform dollar bill seal test at multiple points.
Replace gasket if no tight seal.

Manual defrost to remove frost block

Moderate 3â€“4 hours

Tools Needed: towels, container for water

Unplug fridge and empty contents.
Leave door open to allow frost to melt.
Collect water and dry interior afterwards.
Plug back in and test cooling.

⚠️ Safety First: Do not use hair dryer heat directly on plastic surfaces.

User Suggested Solutions

Check and replace the thermostat if faulty. Ensure the temperature setting is correct. To do this, unplug the refrigerator, locate the thermostat, and use a multimeter to test for continuity. If there's no continuity, replace the thermostat.
Inspect the compressor for signs of failure. If the compressor is not running, check the start relay and overload protector. If these components are functional, the compressor may need to be replaced.
Clean the condenser coils using a vacuum or brush to remove dust and debris. Ensure the refrigerator is unplugged before cleaning. This can significantly improve cooling efficiency.
