I have very important news regarding electric fans. Dati I noticed that the 1st time new fans stop working, parang hindi naman nag-iinit. Then one day I went to the store and bought a KDK -- one of the most expensive fans since according to the Sales Rep, it had a thermal fuse, among other pluses.
Being the mythbuster that I am. I interviewed several electricians and even opened up some fans that were still working.
The conclusion I got was this: MOST new fans have a thermal fuse designed to break the circuit when overheating. When we bring in the fans for repair/rewind, this thermal fuse is not re-attached (presumably since it's extra cost for the repair guy). Thus, older fans that are very old or newer fans that have already been repaired are VERY prone to overheating.
I've since had fuses on all my fans re-attached by a trusted electrician and true enough, NONE of them had their fuses intact.
You get my drift.
PS -- the darn thing costs less than 30 bucks per (may tubo pa yun).
