Why is my Vornado MVH heater making a loud noise?

If your Vornado MVH heater is making a loud noise, it could be due to several issues, such as loose components or a buildup of dust. Heating elements can produce noise as they expand and contract, but if you hear a consistent rattling or buzzing, it might indicate a loose part. Ensure that the heater is placed on a flat surface; if it's on an uneven ground, that could exacerbate noise issues. For example, if the heater is positioned on a carpet, vibrations may amplify. Pro Tip: Periodically check screws and connections to ensure everything is tightened. If the noise persists, consider contacting Vornado customer support for further assistance.
