my heater tips over really easy, the feet don't seem stable on my carpet. anyway to make it less wobbly?
The MVH has a relatively high center of gravity and small, hard plastic feet. On thick carpet, these feet can sink in or tilt, making the unit unstab…
-
the fan speed on low doesn't seem any different than high, it's always blowing really hard.
The MVH is designed as a whole-room circulator first, so even its "low" fan speed is relatively powerful to move air. However, if there's truly no au…
-
is it normal for the plastic casing on my vornado to smell really hot, like a burning plastic smell? it's new.
Yes, this is common for the first few uses of a new MVH (or one that hasn't been used in a long time). It's dust or manufacturing residues on the hea…
