10-2. Checking Continuity of Fuse on PCB Ass'y
Remove the PCB Ass'y from the electrical component box. Then pull out the fuse from the PCB Ass'y. (Fig. 5)
Check for continuity using a multimeter as shown in Fig. 6.

10-3. Checking Motor Capacitor
Remove the lead wires from the capacitor terminals, and then place a probe on the capacitor terminals as shown in Fig. 7. Observe the deflection of the pointer, setting the resistance measuring range of the multimeter to the maximum value.
The capacitor is “good” if the pointer bounces to a great extent and then gradually returns to its original position.
The range of deflection and deflection time differ according to the capacity of the capacitor.
