JVC KW-V820BT Cooling Fan Removal and Replacement

Введение

The cooling fan helps to cool the circuitry inside of the audio device. The cooling fan is controlled by the circuitry in the audio device. The fan may cycle on or off, depending on the temperature of the device. A failing cooling fan may present unusually loud noises when running, or it may not run at all. Once the fan is removed, it is possible to bench test the fan using an appropriate power supply and replace the fan with a compatible unit. Model number and power requirements are detailed on the fan itself. Our fan draws 50 mA at 12V DC.
