Ceiling fan runs backwards

[Glemon]

I have a pair of matched ceiling fans, they have one remote to control both, dimmable lights, reversible fans.

One day I came home and one was pushing down and one was pushing up. Thought they got out of sink, but no South fan will not reverse and only blows upwards.

Since the remote reverses the other fan assume it is not the remote.

I checked the wiring, looked fine, changed the code on the two remotes, South fan will still not reverse when being controlled by its now unique remote.

Looked at the receiver/controller in the housing above the fan. Wiring looked fine, circuit board looked fine.


Had the brilliant idea of reversing wires out of the remote to the fan, thinking I might be able to get it to run in the right direction, no luck.

I see you can get more or less universal remote and receiver sets. Is that worth a shot, or could it be in the fan motor?

My level of electronics understanding as at the 12 Volt DC 1950s car level understanding. Positive negative completed circuit.

Would it be such a thing as pulling the breaker for a half an hour or so and doing a reboot? Are there on board batteries for backup that may need to be replaced or pulled to do a reboot?

 

[Glemon]

It has a manual light switch that has cut the power many times. No on board batteries other than the hand held remote.

Does the fan have a forward / reverse switch on the housing? Check to confirm both are set the same if it has them.

I'd check this too. Most fans I've ever seen has a switch on it somewhere to control its movement forward or backwards

I third this.

switch should be on the housing just above the lights

 

[Glemon]

No manual switches on the fan, all remote. I will triple check when I get home, I installed them pretty sure everything runs from the remotes (and a wall switch which is simple on/off for power).

Can't help, but just so you know you're not alone in fan weirdness. One of our fans with a remote controlled DC motor will sometimes for no known reason turn off for a few seconds and then back on again. Sometimes when you turn it on it will start in the wrong direction for a small fraction of a rotation and then reverse and go in the correct direction.

triple check for sure
the reversing switch is pretty standard for climate changes

I have two DC motor remote only fans, and they both do a partial rotation, stop, then start rotating in the correct direction.
I think it's some sort of internal check.

On the motor housing itself look on the top where it is not visible. If there is a reverse switch, that's where it should be.

Maybe try and pair the remote to the fans
This of course if it's a DC fan and and has remote only reverse
other wise I would think it's a control module

 

[Glemon]

So the fans are reversible via the remote, I would think even in the unlikely event that the switch I wasn't aware of was reversed, the remote would still change the direction of the fan, but it would be out of synch with the other. Nevertheless, can't hurt to check, might help.

 

[Glemon]

Found no switch, thanks for the suggestions.

Lets see a pic or at least a Model Number

 

[Glemon]

I ordered a new receiver remote kit on Amazon, if it doesn't work will return it and get a new pair of fans. The receiver does not have reversing function, so if it the problem is in the motor and not the receiver I am still stuck.

 

[Gunfixr]

The two DC remote fans I have do not have any switches of any kind on the housing.
All control is by the remote, which includes switching directions.
I installed them myself, so I have seen them from all angles.

Hopefully, the controller will solve your issue.

 

[chipdog4]

I have an Emerson fan in my bedroom that changes direction in May or June and then back again in October or November. There is no reversing switch on the fan and no receiver for a remote.
Stupid "smart" technology.
I'm swapping it out within the month.

 

[samss]

Disconnect power to fan 1. Power up and reverse fan 2. Reconnect fan 1.
Fingers crossed.

I’d take the over engineered garbage down and chuck them in the trash and go get some decent fans that are manually controlled.

 

[b-boy]

I have 2 fans with no reversing switch, so they do exist.

You warned not to build dead center of the equator and now you’re complaining?

 

[Glemon]

So I got the remote kit, still runs backwards. I am not ready to give up, further reading suggests it may be the capacitor. Located same, Menards has the exact same capacitor for $5. Going to buy one and try it.

P.S. I think I may know what happened to the fan. I put some LED light strips on a dimmer switch in the living room. Same circuit as the fan. When I have the living room LEDs on and the fan lights, the fan lights would flicker. Something about having two LED dimmers on the same circuit they don't always play well together.

 

[kevomac]

I struggled with this situation for months. If your remote has a fan speed button, try holding it down for about half a second. Any longer it won't work. It also seems to help if the blades aren't turning or are barely turning. It worked for me. Repeatedly, as I have a habit of holding the button too long.

God I miss the 90s. All this modern Chinese **** is garbage, but people just eat it up. especially IOT smart ****.

If my LED garage lights are on there is a good chance the garage door remote in the mirror of my Tacoma will not work. I need to find better lights.

I wish we could have a period of time, say 5 years, we (society) could stop with new useless **** and just make the existing **** work better! Fix software and figure out the problems with the **** we have now so new **** is better. But 5 years is billions (possibly trillions) of dollars of profit that forces me to buy iPhone Y when iPhone T worked fine until planned obsolence.

I'm sorry, I'm kinda bitter about this stuff. Maybe buy AC fans and flip the switch a couple times a year.


(disclaimer). I work in cyber security and i'm tired of upgrades that give more unwanted features and vulnerabilities but don't fix what is currently wrong!

We used to do this in the shop with dc motors to mess with newbs. You spin the motor backwards then turn it on and it will stay running in reverse.

OP needs to spin the fan forward then turn it on and it should stay running in the proper direction.

I'm guessing he had it resolved by 2022...

Maybe, maybe not. Or maybe someone else has a similar problem, which is obviously why a thread a few dozen months old got brought up.

The new spambots are AI driven. They scrape the existing data in the feed and spit out realistically sounding advice using AI google-type searches from the internet. The bot will post 3 or 4 'helpful' posts to look real, and then a few days later will spam the forum. Some are sneaky and will make their spam look like real responses usually with a "here's more details" link to a virus infected web url.

OP had his fans back in the sink. Not sure if kitchen sink or laundry room sink.

 

[WagonHo!]

There was a song in Color Purple the one where Shug sang a remonstrative plea and led the hooch shack imbibers to her Papa’s Chutch. It was called “God is trying to tell you something”.
Or one of the brushes on the fan motor is worn down Enough so it runs backwards.

If you are using the fans to disturb the air and keep the air from forming layers, reverse will not change anything. Have you tried returning the fan?

He's probably outside the return window...

 

[Glemon]

I ended up buying the same model fan (didn't think it was available) in 2022, but thanks for caring guys...
