10.4 Fan motor circuit of the freezing chamber
12 V voltage is reduced to 7~12V through the control chip BD9227F ,output it to F-FAN pin and
connect it to positive pole of fan, to control the operating of fan in different revolution. Check the
voltage between F-FAN pin and GDN pin, to estimate the fan trouble.
10.5 Refrigerator fan motor circuit (None)
