Fart fan speed


Turned on the fart fan in the downstairs bathroom this morning, and all of the sudden it throttled down in speed about 50%.

The switch is not a dimmer (I don't know if that would work anyway) and it's not making any nasty vibrating noises.

Could it just be on it's last leg or is there something wrong with the wiring?

Oil the motor and clean the fan. It might keep it going for quite a while

Look for other symptoms in the house, it may be a bad neutral.
If the fan current draw has gone up the fan bearings might be bad.

Where does it vent out to?
Just a guess if none of the other suggestions work but, a gust of wind blowing into vent from out side could change the speed on one of those small fans.

Fart fan speed


take the cover off, then with an extension cord, unplug the fan from the housing and plug it into the cord. if still slow, it is the fan, if it goes back to normal speed, you have another problem...

Two options -

1 - check the motor is not gummed up !
Take it apart, clean motor shaft and bearings
and apply some clean fresh oil !

2 - Check the capacitor !
A faulty capacitor can cause fans to run slow .

Fart fan speed


LOL first time I hear someone call that a fart fan. I kinda had an idea what it would be before I clicked the thread. :P

It could also be that the racket you heard was because it was out of balance, and somehow it rebalanced itself. My old fan would do that, it would be very loud because it was off balance and the blades were grinding themselves, but it would somehow fall back into balance and run fine for a bit and then start making racket again. Though it's very well possible there is a bad neutral somewhere if it's part of a MWBC, but that's not really common in bathrooms as far as I can tell, but it's a possibility.

I would start by taking it apart and cleaning it as best as possible.

Ive never seen a fart fan with a cap,theyre usually just small single speed shaded pole motors

Fart fan speed


Depending on what style of fan you have a lot of those motors are universal,sometimes you can find a cheap $10-$15 50cfm fan at menards and just use the motor without having to change the whole housing out

Ours takes the same type of fan that a fridge uses for air circulation. Actually stole it once to keep our fridge going.
