Why does my fan stop after a while and then start again?

If your fan cuts out during use, the most likely cause is a built-in safety protection or an unstable power supply. The Tristar fan heater and fans in this range include overheat protection, so a temporary stop can mean the appliance needs to cool down or has been placed where airflow is restricted. Unplug it before checking anything.

Check for a temporary safety shutdown

1. Switch the fan off and unplug it.
2. Let it cool completely if it feels hot or has been running for a long time.
3. Check that the air inlet, outlet and surrounding area are clear.
4. Confirm the socket is working properly and the plug is secure.

Check the environment

1. Move the appliance away from curtains, walls, bedding and other items that may block airflow.
2. Use the fan on a hard, flat and stable surface.
3. For the fan heater, avoid using it in a very cold or very hot room if the appliance no longer restarts as expected.

Read the result

• If the fan starts again after cooling, the protection system was likely triggered.
• If it keeps stopping, or you notice heat damage, unusual smells or repeated tripping, stop using it.

If the problem continues or safe use is uncertain, stop using the product and contact the retailer or store where it was purchased.
