Key Takeaways
- Heat pump compressor failure on a 10+ year dryer almost never justifies repair
- A vented dryer with a major problem should be replaced with a heat pump model for energy savings
- Drum damage (cracked lifters, worn bearings + belt together) signals end-of-life
- Control boards on discontinued models with no available replacement = replace the machine
The Bottom Line
Miele dryers are robust machines, but the heat pump compressor is a single-point-of-failure component that costs as much to repair as a mid-range new dryer. When the compressor goes on a machine over 10 years old, it's time to upgrade.
The Compressor Question
The heat pump compressor is the most expensive component in a Miele T1 dryer, costing From $500 to replace including labour. On a machine under 7–8 years old, this is worthwhile — the rest of the machine is in good shape and has many years of service left. On a machine over 10 years old, you are paying From $500 for a repair on a machine where other components (bearings, seals, electronics) are also approaching end-of-life. The economics do not work.
Repairs That Signal End-of-Life
Multiple Simultaneous Failures
If your technician identifies two or more major issues in a single visit (e.g., worn bearings plus a failing motor, or a compressor problem plus a leaking condenser), the machine is in systemic decline. Fixing one issue will not prevent the next from appearing within months.
Drum Damage
Cracked or broken drum lifters (the paddle-shaped baffles inside the drum) cannot be individually replaced on most models — the entire drum assembly must be swapped. Combined with bearings and seal, this repair approaches From $500. On a machine over 10 years old, this is replacement territory.
Repeated Thermal Cutout Trips
If the thermal cutout keeps tripping despite clean airflow paths and a functioning thermostat, there may be a deeper issue — a partially blocked heat exchanger that cannot be cleaned, degraded insulation, or an intermittent control problem. Diagnosing and fixing these cascading issues often costs more than the repair of any single component.
The Energy Upgrade Factor
If your dryer is a vented or condenser model (not heat pump), any major repair should be weighed against the From $80 annual energy savings of a modern heat pump dryer. A vented model from 2012 consuming $180/year in electricity versus a new heat pump model at $60/year means $120/year savings — $1,800 over 15 years. This often makes replacement the better long-term financial decision even when the repair itself seems affordable.
Still Worth Repairing
For context, these repairs are almost always worth doing regardless of machine age:
- Drive belt: From $100
- Door catch/hinge: From $80
- Thermostat/thermal fuse: From $100
- NTC sensor: From $100
- Lint filter motor: From $120
