Key Takeaways
- Miele dryers under 8 years old are almost always worth repairing
- Belt and sensor repairs pay for themselves many times over
- Heat pump compressor is the make-or-break component — expensive but long-lasting
- A 10-year-old vented dryer with a major problem may be worth replacing for energy savings alone
The Bottom Line
For machines under 10 years old, repair. For machines 10–15 years old, repair if the cost is under $400. For machines over 15 years old, only repair cheap wear parts — major component failures signal it's time for a new machine.
Miele Dryer Lifespan Context
Miele tumble dryers are tested to 20 years of average household use. That said, heat pump dryers have more complex components than vented models, and their most expensive part — the compressor — typically has a 10–15 year working life. A dryer at the 10-year mark is not old, but it is approaching the window where major component costs need to be weighed against replacement.
Always Worth Repairing
| Repair | Cost | Reasoning |
|---|---|---|
| Drive belt | From $100 | Cheapest and most common fix |
| Thermostat / thermal fuse | From $100 | Safety part, always replace |
| Door catch / latch | From $80 | Simple swap, any age machine |
| NTC sensor | From $100 | Inexpensive, restores temperature control |
| Lint filter motor | From $120 | Functional necessity, affordable |
Depends on Age and History
- Drum bearings (From $250): Worth it if the machine is under 12 years and has no other problems. Not worth it if other components are also showing wear.
- Control board (From $300): Worth it if the board is available and the machine is under 10 years. For older machines, check availability before committing — discontinued boards have long lead times.
- Heat pump compressor (From $500): Only worth repairing if the machine is under 8 years old. After that, the cost approaches replacement territory and you miss out on efficiency improvements in newer models.
The Upgrade Argument
If your current dryer is a vented or condenser model, replacing it with a modern heat pump dryer saves approximately From $80 per year in electricity. Over a 15-year lifespan, that is $1,200–$1,800 in savings. This tips the repair-vs-replace calculation toward replacement for older non-heat-pump machines with major problems.
