Manual Extract: Sun load sensor

Solar radiation sensor
This is the air conditioner solar radiation correct sensor. It detects the strength of sunlight with a photodiode, converts it into milli-amp and sends that to the controller.

Solar radiation sensor inspection method
• Disconnect the solar radiation sensor connector from the harness and measure the voltage between the sensor side connector terminals using the tester’s voltage measurement mode. The voltage must be different when light is striking the photoreceiver section and when it is not. (The voltage is about 0 V when absolutely no light is striking the photoreceiver.)

NOTICE: Always measure with the tester in voltage measurement mode (V mode). Measuring in resistance mode (Ω mode) would destroy the sensor
