When a tumble dryer runs but produces no heat, it can be confusing. The drum spins, the timer moves, and everything appears normal, yet your clothes come out cold and damp. This fault is one of the most common dryer problems in the UK and the repair cost can vary widely depending on what has failed.

Some heating issues are minor and inexpensive. Others involve major electrical components. Knowing the difference can help you avoid overpaying or replacing a dryer that still has years of life left.

How heating systems work in tumble dryers

Most tumble dryers generate heat using a heating element controlled by thermostats and sensors. Air is pulled across the element by a fan, circulated through the drum, then expelled or condensed depending on the dryer type.

If any part of this system fails, heat production stops or becomes inconsistent.

Common reasons a dryer stops heating

  • Burnt out heating element
  • Blown thermal fuse
  • Faulty thermostat
  • Blocked airflow
  • Broken control board
  • Defective moisture sensor

Typical UK repair costs

Prices vary by brand, location, and dryer type, but most UK homeowners see the following ranges.

  • Heating element replacement: £110 to £190
  • Thermal fuse replacement: £50 to £90
  • Thermostat replacement: £60 to £120
  • Moisture sensor replacement: £70 to £130
  • Control board replacement: £160 to £320
  • Call-out fee: £40 to £70

A full repair normally lands between £120 and £240 for most heating faults.

What makes heating repairs expensive

Heating systems involve high temperatures and electrical safety controls. Engineers must test multiple components to find the true fault. In many cases, more than one part has failed.

For example, a blocked vent can cause overheating, which then blows the thermal fuse. If only the fuse is replaced, the dryer may fail again.

Is it safe to keep using a dryer with no heat

Running a dryer that does not heat can strain the motor and fan system. Cycles take longer, which increases wear on moving parts. In some cases, overheating can still occur due to airflow problems.

If your dryer is not heating, it should be checked.

Repair or replace decision

If your dryer is under 6 years old, heating repairs usually make sense. If it is over 10 years old and needs a control board or multiple parts, replacement may be cheaper long term.

Final thoughts

Heating faults are common and usually fixable. Most repairs fall into a sensible price range if the dryer is not too old. The key is proper diagnosis. Replacing the wrong part wastes money.
