1. Indoor or Outdoor DC Fan Motor (control chip is in fan motor)
Power on and when the unit is in standby, measure the voltage of pin1-pin3, pin4-pin3 in the fan motor connector. If the voltage value is
not in the range shown in Table 17 and 18, the PCB is faulty and needs to be replaced.
• DC motor voltage input and output (voltage: 220-240V~):
Table 17 — Voltage
•DC motor voltage input and output (voltage: 115V~):
