3) Checking the Electrical Parts

Power transformer ...........................Indoor unit *Measure the coil resistance.

• Primary 230-208 V ; Measure the resistance between two WHT lead wire terminals

of socket connected to power transformer.

• Secondary 19 V ; Measure the resistance between two BRN lead wires.

Power transformer (TR) ................. Outdoor unit *Measure the coil resistance.

• Primary 230-208 V ; Measure the resistance between two WHT lead wire terminals

of socket jointed to power transformer.

• Secondary 19 V ; Measure the resistance between two BRN lead wires.

Indoor fan motor (FMI) ............... Indoor unit *Measure the coil resistance.

• Measure the resistance between each terminal of the socket connected to the

indoor fan motor.

Outdoor fan motor (FMO) ........... Outdoor unit *Measure the coil resistance.

• Measure the resistance in the same manner as explained above 2 .

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. 21. Observe the deflec-

tion of the pointer, setting the resis-

tance measuring range of the multim-

eter to the maximum value.

• The capacitor is “good” if the pointer

bounces to a great extent and then

gradually returns to its original posi-

tion.

The range of deflection and the deflection

time differ according to the capacity of the

capacitor.
