it should be a simple slide switch on the side of the housing that moves up and down to change the direction of rotation of the fan motor and blades. look at the manual that came with the fan to make sure it has this feature but i personally have never seen a fan without one.
The motor may just need a good blowing out. If you can remove the fans motor and use compressed ait it can be cleaned thoroughly. First tun the motor by hand to see if it spins freely. It may have a dried up bearing locking up the fans shaft to the motor causing it to have stop. YThe bearings have a flat colored seal which can be popped off to relube then snap the seal back in
I had a hampton bay fan that absolutely did not have a revers switch on the fan anywhere! MOST fans bought today will reverse. I was not about to give up. I scoured the net for an answer and could not find anything to help. I did however find a comment somewhere that said it could be done internally. After about six months I decided to search again (now). Nothing... so I started playing with the remote and the wall switch and Shazaam! I figured it out on my hampton bay fan. Turn the fan on high... Turn the wall switch off.... wait until the fan is pretty slow in rotation... hold the HI button on the remote.... Turn the switch back on. IT Worked for me! Hope this helps someone. SparqMark
you have 3 control wires (the 3 speeds) and a common wire. the common wire will go directly from the fan motor to the power source/cord and the other 3 leads will run through the switch. you could even use a standard dimmer-style lighting rheostat and connect it to the common and "high" fan speed wire and have infinitely variable fan speeds. hope that helps.
I need to verify you have adaquate air flow, to cool the motor. If you have a window open, and the crawl hole open is there enough air flow into the the attic? It there is enough air flow and it still stops after about an hour, does this unit have a humidistate and a temperature switch on the housing or extension. If all the switches are working correctly then I could be the motor overloading/heating shutting down and then reseting. InMrFixIt
It sounds like the electronic controls have put the fan into "breeze mode". The fan turns slowly then is supposed to surge back to high. Some people love this feature for some reason... Disable breeze mode via your remote (its the button with the stacked ~'s).
A bad motor wouldn't rotate at all. The only other problem might be the motor's running capacitor. If you can start the fan in either direction (give it a hand spin in the opposite direction of rotation) you have a bad capacitor...and you can find a replacement anywhere (Radio Shack).
Read this on another thread - apparently the solution came from HB's tech support.
Turn the fan speed to HI and then select Reverse. You should hear a "click" and see the fan reverse direction. It seems that the reversing relay only works when the fan speed is set to HI.

I recently replaced my hampton bay fan for the same reason (slow at all speeds) and discovered scorched and melted capacitors and wiring inside the fan. My suggestion is to stop using fan and replace immediately.
