Re: hawaiian breeze fan

Maybe too late to help this case, but I recently fixed a similar problem on a Honeywell HFY-045-THA Tower fan. The 5v rail is derived the same way through a 1.0μF X2 uTx brand direct from the hot lead through a dropper to a 5.1v zener. Selecting 'ON' would briefly blip the fan, then nothing.
Turned out the derived supply was not "stiff" - the load of driving a couple of triacs and led indicator collapsed the supply and caused the MPU to reset. This happened fast enough, the LCD display remained blank.
The culprit was the X2 cap...
