My transformer not working ? how to replace the fuse.

Fuses often blow when you are drawing more current then what the transformer can provide. They are part of the inbuilt safety protection of our transformers.

If you keep blowing a fuse repeatedly  then something is wrong - you have likely purchased the wrong transformer.

All our new stepdown transformers come with a red LED switch, if the Light on the LED does not come on when transformer is turned on its an indication the fuse has blown

HOW TO REPLACE THE FUSE:

1) Turn off the power at the 240v power point

2) Unsrew the fuse Holder

3) Turn it anti-clockwise until the fuse "pops out"

4) Remove the fuse holder plus the fuse

5) Check the fuse if it is open current

Look at it in the light and if the inside filament is broken or the glass is browned out then the fuse is blown. Note: if you fuse is ceramic (covered in white paper) there will be no way of checking this unfortunately. .

6) Put a new fuse in the holder

7) Peace back into the fuse main body

8) Turn the fuse holder clockwise until its locked in

9) Turn the power on at the 240v outlet
