Why is my Vornado heater making noise?

A Vornado heater may make noise due to its fan operating, which is normal as it circulates warm air throughout the room. However, if you notice unusual sounds like rattling or grinding, this may indicate an issue. Ensure that the heater is set up on a stable surface and is free from debris. If the noise persists, it may require servicing. For example, if you've moved the heater recently and it’s now making rattling sounds, check for any loose parts. Pro Tip: Regularly inspect and clean the heater to prevent dust buildup that can lead to operational noise. Consideration: If the noise becomes disruptive or alarming, discontinue use and consult the user manual or a technician.
