Figure 2: Checking switching components
1.
Resistance value between two legs should be around 9 kΩ-10kΩ.(See Figure 3).
Otherwise the switching element has been short circuited and main board must be changed
with new one according to the instructions.
Figure 3 Resistance value
2.
Any main board failure may cause malfunction at the fuse through filter board. Short
circuit control is done by using multimeter.(see Figure5). If there is an open circuit between
two points, the filter board must be replaced with new one.
