2. Broken Soldering Iron Cord
There are two methods of
testing the soldering iron cord.
3. Replacing the Fuse
1. Turn the unit ON and set the temperature control knob
to 899°F.
Then wiggle and kink the iron cord at various locations
along its length, including in the strain relief area. If the
LED heater lamp flickers, then the cord needs to be
replaced.
CAUTION! The LED heater lamp will flicker even
with a normal Iron cord if the temperature reaches
899°F.
2. Check the resistance between the pin of the plug and
the wire on the terminal.
Pin1: Black Pin2: Yellow Pin3: Green
Pin4: White Pin5: Red pin the value should be 0Ω. If it is
greater than 0Ω or is ∞, the cord should be replaced.
Refer to the drawing on the parts list. Desolder the Blown
fuse and remove it. Solder the new one.
