Re: hawaiian breeze fan
If it's anything like this electronic air cleaner I fixed-
Five leads from the motor, one for each speed plus common to neutral.
Those are triacs on that board, one for each speed.
This appears to be doing the same as that EAC, right down to the confused micro.
In my case, the resonator checked out, the caps in the 'power supply' were replaced, even another 5V supply was substituted. Never got anything other than a fan twitch. The lights would pulse brightly during the twitch, then stay dim for 20 seconds. There was an LCD that never displayed anything. It had its own chip and got data from the micro.
I ripped all that junk out and put in a rotary switch for the fan, and two toggle switches- one for main power and the other for the ionizer. I think someone 'charged up' after removing/replacing the collection cell and 'discharged' into the circuit board when using the control panel.
Ah, yes. One of those cheap capacitive voltage divider supplies. See my diagram.
