I purchased my Vornado VH202 heater October 2020 and at first, it worked great but then one day I tried to turn it on but nothing happened.  I waited a few hours and tried again and then it turned on without any problems.  Fast forward to now.  It was working fine until January 17, 2021 when I turned it on and it made an odd ticking-like noise.  I used it that day and have been using it ever since but each time I turn it on, it lets out the same ticking sound.  The ticking sound is not permanently ongoing while it is on but it is rather annoying each time I turn it on.
