Last updated: 4 September 2026
Quick Answer
Check the heating element, the thermostat, and the thermal fuse.
Overview
A tumble dryer that does not heat will not dry clothes effectively. This guide covers diagnosing and fixing the issue.
Step-by-Step Fix
Safety & Preparation
Before beginning any repair, ensure you have isolated power or water supplies. Clear your workspace, gather standard hand tools, and wear appropriate personal protective equipment (PPE).
- Before attempting any repairs, always switch off the tumble dryer at the mains electricity supply and then unplug it completely from the wall socket. This crucial safety step prevents electric shock during the repair process.
- Carefully unscrew and remove the back panel of your tumble dryer, typically held by several screws, to gain access to the internal components. Once the panel is off, locate the heating element assembly, which usually looks like a coiled metal tube or a box with wires attached.
- Set your multimeter to the continuity setting (often indicated by a speaker icon or ohms symbol) and touch one probe to each terminal of the heating element. A healthy heating element will show a reading of continuity (a beep or a low ohm reading), indicating the circuit is complete; if there is no reading or an 'OL' (open loop), the element is faulty.
- If your multimeter shows no continuity for the heating element, it is defective and needs replacing. Purchase a new heating element specific to your tumble dryer model and carefully install it, ensuring all wires are connected securely before proceeding.
- Next, locate the thermostat and thermal fuse, which are usually small, disc-shaped components attached to or near the heating element housing. Use your multimeter's continuity setting to test both the thermostat and the thermal fuse individually; if either component shows no continuity, it is faulty and must be replaced.
- Once all checks and replacements are complete, carefully reattach the back panel of the tumble dryer, ensuring all screws are tightened securely. Plug the dryer back into the mains socket and switch on the power, then run a short cycle to confirm it now heats correctly.
