Triac board that feeds the fan on Williams Whirlwind.

Hoots Roller Bar over on Mill Works Road in Winston-Salem has a nice Whirlwind. Before that, they had a Judge Dredd in the pin spot that I did some work on occasionally. It’s a great bar that brews their own craft beer on site and has a wonderful atmosphere — I highly recommend anyone in the Triad area check it out if they haven’t already!

Their fan on Whirlwind had blown a fuse and wasn’t working. The fan runs off of a combination of connectors from the Sound Overlay/Solenoid Board and the Auxiliary Power Driver board. They run through a small Triac board that is rather inconveniently screwed into the top of the backbox.

Sometimes this little triac board gets cold and cracked solder joints over time that can cause the fuse on the triac board to blow. That ended up being the case with this one; several of the joints including C2 were completely cracked through to where the lead of the component could be seen moving in and out. I re-flowed all the joints on the solder side of the board, put in a new 5 amp slow-blow fuse and it’s working great.
