5Motor capacitor ............ Both in indoor and outdoor unit

•Remove the lead wires from the capacitor terminals, and then place a probe on the capacitor terminals as shown in Fig. 26. Observe the deflection of the pointer, setting the resistanc 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.

NOTE

The range of deflection and the deflection time differ according to the capacity of the capacitor.

6Continuity of fuse on P.C.B. Ass’y

•Check for continuity using a multimeter as shown in Fig. 27.

NOTE

Method Used to Replace Fuse on PCB Ass’y

1.Remove the PCB Ass’y from the electrical compo- nent box.

2.Remove the fuse from PCB Ass’y using pliers while heating the soldered leads on the back side of the PCB Ass’y with a soldering iron (30W or 60W). (Fig. 28)

3.For replacement, insert a fuse of the same rating to the intended position and solder it.

(Allow time to radiate heat during soldering so that the fuse does not melt.)

When replacing the fuse, be

CAUTION sure not to break down the varistor.
