although there's no rational reason why you would. the only fans that I can find a rational reason to run on high reverse. are my 52" bright brass charleston and my home-made blender-fan which is in my parents house. in both cases there are vents above the fans. which allows me to blow heat from my pellet stove and my parents to blow heat from their wood stove from our basements to the first floors of our houses.

In both of the cases you picture, it still looks like it would make more sense to run them in downdraft. Of course you are able to try all different settings and would know which are best.

i sometimes run my casablanca on high reverse, and when i turn the fan on by the wall switch, the entire motor moves a quarter of a turn the same way that the blades turn and it stops after that , other then that, i ususally run it on low or med

I usually reverse my fans in the winter, but this year I didn't bother - I just left them on downdraft.

Well for you Richard with that sub tropical climate you have in New Orleans its understandable you don't really see the need to reverse it.
Here in Montréal with a full 4 season climate where each seasons is very distinctive and we are always between two seasons the reverse feature gets use a lot. I just cannot pretend that I'm OK with fans downdraft at this time of the year. If I don't reverse them I'm freezing...even with a fan spinning at 40-55RPM.

Sorry for the bump, but what about also checking to make sure if something that supports the fan can tolerate fan on high on reverse? Hampton Bay Gazebo at Dave & Buster's (seen at m.youtube.com/watch?v=H2qP9buQJnk ) is installed on a long downrod. It hadn't been on high for about 7 years, then it ran on high since last fall. When I saw it around last Christmas, I noticed that the chain, screws on canopy, and sticker on upper downrod weren't in same place as it was when I went there around last Thanksgiving. For a proof: And it had been in the same place since then. I never saw it on reverse, but if it had ran on high on reverse for long time, do you think it would fall down, or there could be something that keeps it from falling? And since that video also has Hunter Infinitis, I might be getting an identical one from a house awaiting to be demolished (for those who don't know).

If the fan was ball/socket, had one metal bar running through the ball, and had another running through both the downrod and the fan motor (as most current cheap fans do) then my guess is you'd be relatively safe. Then again, I'm not sure these cheap fans would be capable of creating enough torque to actually spin themselves loose lol.
If the fan can change its position while running on high forward, it certainly can while on high reverse. Even if it's locked in a position where it can't twist itself loose from the ceiling, there can be a problem with the mounting system (such as the "tooth" of the bracket not being aligned with the slot in the ball, or even worse the "tooth" being missing altogether) which could cause the fan motor to rotate until eventually the wires get twisted up inside the downrod to a point where they fatigue and short out in one of many different ways, creating a fire hazard.
EDIT: Oops, I totally missed what you were asking. I guess theoretically something could be wrong with the actual support that holds the fan, and you'd definitely want to have that checked out regardless of what direction that fan is running. If it can't hold the fan still PERIOD, it needs to either be reinforced or changed out. Like I said, even if it can't twist itself free, it can twist the wires inside of it.

I thought about speaking to the manager about it, but one thing that keeps me from doing it is that there is a Lutron Skylark dimmer or solid state speed control on the ceiling which was close to minimum setting for about 6 years and it went back to full setting around the time it was remodeled which was October 2012, and I'm worried if someone checks the mounting, he would also put the switch away from full setting. And I don't want it to burn out the motor considering it's a 16 pole motor (which can't be on solid state speed control) and Gazebo IIs aren't as good.

Leave it alone. It's been fine for years.

Leave it alone. It's been fine for years. Yeah, it had been on forward for years. It is installed around 1994 when this D&B was put in. If I ever see it on reverse, I'll try to reverse it to forward to make sure it doesn't twist off.

And what if the capacitor or something goes bad which causes the fan to reverse itself, and nobody notices it until it falls down?

I have a Casablanca Panama XTR in my dining room that is always on high reverse, simply because I want to feel the air pushed into the living room, and it is WAY too powerful to blow down, I would never use it while I was eating and it would essentially cool an area I only occupy a few minutes a day. My other fans always run forward. However, I do check the set screw from time to time, and so far it is very much locked in as the day I installed it. And it better stay that way...lol. Is that a fan I should really be concerned about spinning off it's pipe? It does have a ton of torque and 20 degree pitch... I'm pretty sure a new Casablanca would have the bar going across through the motor and downrod, and another in the canopy ball, to keep the fan from falling. I can't think of any currently made fans, except maybe some Hunters, that don't have this feature nowadays. Yeah, Hunter seems to have a downrod that screws in without a bar. They seem to have a red loctite, and a set screw. Apparently, a set screw alone is enough to prevent the motor from unscrewing from downrod, but I'm guessing Hunter put a red loctite in case someone doesn't tighten the set screw enough. I did remove the loctite from a 2' downrod of my Hunter Infiniti, by flipping it over (downrod is double threaded, but ball doesn't screw in, just uses a pin.) I just need to work on the loctite in the motor, when I get around to it. And downrod for my Infiniti has holes on threads, and if you screw a set screw through a hole, it would make it absolutely impossible for it to fall while running on reverse.

About the fans reversing itself, this has happened to Tais's TMT, and Adam's Evergo which was caused by a capacitor. And Cole's Moss Caribbean Breeze reversed itself, and it wasn't a capacitor. So even if the fan is non-reversible, and if you need to leave it on high all the time for some reason, it will still be more safe to make sure it doesn't twist itself off easily when the fan reverses itself.
