Measure the resistance of the outdoor discharge pipe
temperature sensor
For safety reason and to prevent
component breakdown, always switch
off the power before remove and
connect the component.
Is the measured resistance of the outdoor gas pipe
temperature sensor matches the value specified in its
characteristic chart?
