REPAIR INSTRUCTIONS
Replace the Motor
Temp Sensor
1� Get a replacement sensor and
put the metal piece where it is
in good contact with the motor
coil� Fix it to the coil using heat
proof silicone� The coil shouldn’t
reach temperatures higher than
150 °C (302 F), so that is a good
specification for the silicone.
2� Be sure to secure the white wires
to the coil in a couple of places
along the way to where the cables
exit the motor�
3� Cut and peal the blue and brown
wires as close to the coil as
possible without harming the coil
or the other wires�
Slide on a couple of centimetres
of heat shrink tube on each one
of the wires before soldering them
together�
Solder one white wire to the blue
one and the other white to the
brown, which one doesn’t matter�
Slide the heat shrink over the
solder so it is completely covered
and shrink it using a heat gun�
Some motors have a functional
additional temp sensor� Then jump
to step 3�
