JVC HX-GD7 component system problem...?

Good day!!! the problem occurs when i noticed that the exhaust fan (16 amps with 3 wires: red, black and yellow) of my component heres the image (http://uk.shopping.com/xPF-JVC-HXGD7) is already dead but the system still working and when i play audio cd or cd containing mp3 or even cette tape the system plays normal but in a few minutes it stops and go back to standby. Is the exhaust fan really the culprit??? it's the first time my component behaves this way. Should I replace the fan? What should i do? i'm gladly appreciate all who help
