Pedestal fan

I am trying to repair a 11 month old fan. Have tested the motor, ok, so fault is with the PCB.
Q1 Input voltage is 230vac and after the fuse their is a resistor 330k, will it be ac or DC after the resistor?
Q2 the ic is unmarked, how do I find out what it is?

Take a picture, well focused, both sides of board.

A resistor drops voltage, but does not "convert" it. A rectifier converts
AC to DC, also solid state switches like MOSFETs can convert AC to DC,
and vice versa. You can have AC on one side of a R, DC on the other, or
AC on both sides or DC on both sides, depends on the circuit and its design.


Regards, Dana.
