When a tumble dryer refuses to start at all, it feels like the worst possible outcome. No lights, no sound, no movement. Many people assume the machine is dead and start shopping for a replacement. In reality, a non-starting dryer often has a simple fault that can be fixed at a reasonable cost.

The key is understanding what has failed and whether it is a safety feature doing its job.

Why dryers fail to start

Dryers are designed with multiple safety systems. If any of them detect a risk, the machine will not start. This protects you from overheating, electrical faults, and mechanical damage.

  • Faulty door switch
  • Blown thermal fuse
  • Failed start switch
  • Power supply issues
  • Broken control board
  • Worn motor

The door switch is one of the most common causes. If the dryer thinks the door is open, it will not run.

How engineers diagnose a no-start fault

Diagnosis usually begins with power testing. Engineers check whether electricity is reaching the machine and whether it is being distributed correctly.

Next, safety circuits are tested. These include the door switch, thermal fuse, and high-limit thermostat. If any of these are open circuit, the dryer will not start.

Only after these checks do engineers test the motor and control board.

Typical UK repair prices

  • Door switch replacement: £60 to £120
  • Thermal fuse replacement: £50 to £90
  • Start switch replacement: £60 to £110
  • Motor replacement: £160 to £280
  • Control board replacement: £160 to £320
  • Call-out fee: £40 to £70

Most no-start faults are repaired for between £80 and £160.

When this fault becomes expensive

If both the motor and control board have failed, costs can rise quickly. This usually only happens on very old machines or those that have been repeatedly overloaded.

If your dryer is over 10 years old and needs a major electrical part, it may be time to compare with old tumble dryer repair costs.

Should you keep trying to start it

No. Repeated attempts can damage electrical components. If the dryer clicks, buzzes, or trips the electrics, stop using it.

Many people turn a minor safety fault into a major repair by forcing the machine to run.

How this compares to other faults

No-start faults are often cheaper than heating or motor problems. They usually involve switches, fuses, or wiring rather than major components.

Final thoughts

A dryer that will not start looks like a total failure, but it rarely is. Most faults are safety-related and inexpensive to fix. Early diagnosis keeps costs low.
