1. Turn the nut (1) countercloc-
kwise and remove the tip
enclosure (2), and the tip (3).
2.
Turn the nipple(4)counterc-
lockwise and remove it
from the iron.
3. Pull both the heating element
(10)
and the
cord
assembly(11)
out of the handle(7).
(Toward the tip of the iron).
4.Do not use metal tools such
as pliers to remove tip or tip
enclosure from-the handle.
Measure when the heating ele-
ment is at room temperature.
1. Resistance value of heating
element(White) under 1Ω.
2. Resistance value of sensor
(Red and Green) under 10Ω.
If the resistance value is not
normal, replace the heating el-
ement (Refer to the instructions
included with the replacement part.)
After replacing the heating
element.
1. Measure the resistance value
between 1) pins 4 & 1 or 2.
2) pins 5 & 1 or 2. 3) pins 6 &
1 or 2. 4) pins 6 & 4 or 5.
If it is not ∞, the heating
element and sensor are
touching. This will damage
the P.W.B.
