Hi fellow EEVblog friends,
I have a ceiling fan with remote controlled speed controller. This speed controller is attached to the ceiling fan. It can be controlled via handy-remote control unit.
The problem is, it stop spinning last month. The speed controller is receiving input from the remote controller because it still producing sound through its buzzer. I have read several post from several forums and guide to repair ceiling fan that wont spin and decided to replace the capacitor for a try.
After replacing the start-capacitor (i believed through my readings that this type of capacitor does not have polarity), and switch it on, the fan still wont spin but after around one minut it spin for a momment. I get this twice.. but after that I heard a pop n some sort of fire/spark come out of the speed controller.
Analysing the board, I got TWO component burnt. That TWO component is:
1 - Fusible resistor (0.5 Ohm 5% 1W)
2 - Diode (1N4007)
I can easily replace the diode. But for the fusible resistor.. Its hard to search and find the same component because that fusible resistor is cement/some type of flameproof material coated. The one that I need look like a standard resistor (FKN in the attached image). Can I use the white cement resistor (FSQ) to replace it?
