TUMBLE DRYER FAULTS

Tumble Dryer Keeps Stopping

A dryer that repeatedly stops may be overheating, losing the door-switch signal, detecting a dry load incorrectly or suffering a motor or control fault.

!

Switch off and unplug before cleaning inside, removing panels or checking moving parts

Tumble dryers combine mains electricity, high heat, lint and rotating components. Stop using the appliance if it overheats, trips the electrics, smells burnt or makes grinding noises.

MOST LIKELY CAUSES

Start with these

Overheating Blocked airflow can trigger thermal protection.
Door switch fault Vibration may interrupt the safety circuit.
Motor thermal cut-out A failing motor may stop as it heats.
Sensor or control fault The dryer may end cycles incorrectly.
◫ Symptom variations Match the exact point in the drying cycle. ⌄
  • Stops after a few minutes
  • Restarts after cooling
  • Display remains on
  • Door light flickers
  • Stops only with heavy loads
✓ Quick checks Simple checks before removing panels. ⌄
  1. Note when the fault appears.
  2. Clean all accessible lint filters.
  3. Check the load size and programme.
  4. Inspect visible vents, condenser parts and the power lead.
  5. Unplug before touching internal parts.
If airflow was the cause: performance should improve immediately.
If electrical or mechanical faults remain: stop and call an appliance engineer.
1 Step 1 — Clean filters and vents Switch off and unplug before opening panels or touching internal parts. ⌄

Process

Remove all accessible lint and confirm airflow.

Success looks like: The dryer completes the cycle.
Escalate when: If it still stops, a component fault is likely.
2 Step 2 — Check the door closes firmly Switch off and unplug before opening panels or touching internal parts. ⌄

Process

Inspect the latch area for lint, damage or looseness.

Success looks like: The safety switch stays engaged.
Escalate when: A loose or intermittent switch needs replacement.
3 Step 3 — Test with a smaller load Switch off and unplug before opening panels or touching internal parts. ⌄

Process

Run a light load on a suitable programme.

Success looks like: The machine runs normally.
Escalate when: Stopping under all loads points to motor or control issues.
⌁ Common causes explained Why tumble dryer faults develop. ⌄

A dryer that repeatedly stops may be overheating, losing the door-switch signal, detecting a dry load incorrectly or suffering a motor or control fault.

Airflow and heat are the biggest clues. Poor airflow causes long drying and overheating, while belt, motor and bearing faults affect drum movement and noise.

⌘ Advanced diagnostics Appliance-engineer checks and repair work. ⌄
  • Test door switch continuity.
  • Check motor thermal protector.
  • Inspect moisture and temperature sensors.
  • Verify fan airflow.
  • Test control-board power and relays.
▣ Parts that may need replacing Common components linked to this fault. ⌄
  • Door switch
  • Motor
  • Thermal protector
  • Moisture sensor
  • Control board
! When to call an appliance engineer Conditions that should end basic troubleshooting. ⌄
  • The dryer trips the electrics.
  • The cabinet overheats or smells burnt.
  • The drum is seized, grinding or not turning.
  • Internal electrical testing is required.
  • The dryer must be dismantled.
  • The same fault returns after basic cleaning.
? Frequently asked questions Common tumble dryer questions. ⌄

Why does the dryer stop and restart after cooling?

Thermal protection may be operating because airflow is restricted or a motor is overheating.

Can lint cause a fire?

Yes. Filters, vents and condenser areas should be kept clean and the appliance should never be used while overheating.

Should I keep resetting the electrics?

No. Unplug the dryer and arrange fault testing.
