Motor 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.

Continuity 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.)
CAUTION
When replacing the fuse, be
sure not to break down the
varistor.
