Error codes help pinpoint the system that’s failing. We interpret the code, verify it on-site, then quote the repair.
Miele: Not Cooling
When a refrigerator stops cooling, the cause is usually airflow, compressor start components, or a sealed system issue.
- Check evaporator fan motor operation
- Inspect condenser coils and condenser fan
- Test compressor start relay and overload
Quick tip: Clean the condenser coils and make sure food items are not blocking air vents inside the fridge.
Learn more →Miele: Running Too Warm
If temperatures are higher than normal but the unit still runs, the issue is often restricted airflow, dirty condenser coils, or weak cooling performance.
- Verify actual temps vs setpoint (fresh food + freezer)
- Check evaporator fan airflow and damper operation
- Inspect condenser coil cleanliness and condenser fan
Quick tip: Set the fridge to the recommended temperature and wait 12–24 hours. If temps don’t stabilize, book a diagnostic.
Learn more →Miele: Freezer Section Not Cooling
When the freezer section warms up, it’s often a defrost issue, fan failure, or airflow blockage from frost buildup.
- Inspect evaporator coil for frost/ice blockage
- Test evaporator fan motor operation
- Check defrost heater and defrost thermostat
Quick tip: If there’s heavy frost on the back wall, limit door openings and book service—airflow is likely blocked.
Learn more →Miele: Ice / Frost Buildup
Excess frost usually points to a defrost system failure, door seal leak, or airflow/damper problems.
- Inspect door gaskets and sealing surfaces
- Check defrost heater continuity and defrost thermostat
- Verify defrost cycle operation (board/timer)
Quick tip: Check the door gasket for gaps and make sure nothing prevents the door from closing fully.
Learn more →Miele: Not Defrosting
If the evaporator ices over, cold air can’t circulate. This is usually a defrost heater/thermostat/control issue.
- Test defrost heater for continuity
- Test defrost thermostat/bi-metal (temperature dependent)
- Verify defrost control board outputs
Quick tip: If airflow is weak and frost is heavy, don’t keep running it for days — it can stress the compressor.
Learn more →Miele: Leaking Water
Most refrigerator leaks are caused by a clogged defrost drain, drain line issues, or a faulty water inlet system.
- Inspect and clear defrost drain and drain trough
- Check drain line routing for kinks/backflow
- Inspect water inlet valve and supply line connections
Quick tip: Look for ice buildup near the drain area and clear visible debris. If leaking is active, shut off the water supply.
Learn more →Miele: Making Loud Noise
Unusual refrigerator noises usually come from fan motors, ice/frost contacting a fan blade, or compressor vibration.
- Inspect evaporator fan motor and shroud
- Check condenser fan blade and motor
- Verify compressor mounting and vibration points
Quick tip: Make sure the refrigerator is level and not touching cabinets or walls—vibration can amplify noise.
Learn more →Miele: Door Not Sealing
A poor door seal causes temperature swings, frost buildup, and longer compressor run times.
- Inspect gasket condition and magnet seal
- Check door alignment and hinge wear
- Inspect sealing surface for warping/debris
Quick tip: Try the paper test: close the door on a sheet of paper. If it slides out easily, the seal may be weak.
Learn more →Miele: Compressor Running Constantly
Constant running typically means the unit can’t reach set temperature due to airflow blockage, dirty condenser, weak compressor, or sensor issues.
- Inspect condenser coil and airflow around unit
- Check door seals and air leaks
- Verify thermistor/sensor readings vs actual temps
Quick tip: Vacuum the condenser area and ensure ventilation clearance. If temps don’t improve, book a diagnostic.
