The heater and temperature sensor assemblies are
clipped into the fan assembly. In case the
temperature sensor or the heater assembly fails,
they can be unclipped separately from the fan
assembly.
If the fan is defective, unclip both, the temperature
sensor assembly and the heater assembly from the
fan as described in the next steps.
3 If required, remove the sensor out of its holder.
