Smile ELBA tower fan keeps blowing resistor

Hi all,
Got this ELBA tower fan model ETWF-B3740RC from my sister saying her technician could not repair it.
Upon opening the plastic case, I found one resistor(brown,black,black,gold)at R1 slightly charred. On the pcb, R1 has 10R 1W silk printed. I tested the original resistor using a digital multimeter and it showed nothing and conclude it must be faulty. So, I replaced with a 10ohm metal film resistor of a bigger size. Upon power on, I heard a spark and the new replaced resistor is blown.

The 2A glass fuse still has continuity and I do not see any other burned component beside the 10 ohm resistor.
Can someone experience to assist and guide me where else to check for any short or fault causing the resistor to blow. Appreciate your help and patience to reduce electrical aplliance being thrown to dumpster.
