1.The photo sensor is located at the center of the defrost nozzles.
2.The photo sensor contains a photovoltaic (sensitive to sunlight) diode. The solar radiation received by its light receiving portion, generates an electromotive force in proportion to the amount of radiation received which is transferred to the automatic temperature control module so that the solar radiation compensation will be performed.
1.Emit intensive light toward the photo sensor using a lamp, and check the output voltage change.
2.The voltage will rise with higher intensive light and reduce with lower intensive light.
