What to do if my Vornado MVH heater smells bad?

If your Vornado MVH heater emits a bad smell, it’s important to address it immediately to ensure safe operation. Often, a burning smell is due to dust accumulation on the heating elements, especially if the heater has just been turned on after a long time. Over time, dust can settle and burn off, creating an unpleasant odor. It’s recommended to turn off the heater, unplug it, and clean the exterior and accessible parts using a soft cloth. For instance, if you notice a strong burning plastic smell, it could be a sign that the unit is overheating or has a damaged component. Pro Tip: Regularly clean your heater to prevent dust buildup for optimal performance. However, if the smell persists after cleaning, it may indicate a more serious issue that requires contacting customer support or a professional.
