Outdoor unit
(1) Capacitor charge fault (Fault with outdoor unit) (AP1 below refers to the outdoor control panel)
Main Check Points:
Use AC voltmeter to check if the voltage between terminal L and N on the wiring board is within 210VAC~240VAC.
If the reactor (L) is correctly connected? If the connection is loose or fallen? If the reactor (L) is damaged?
Fault diagnosis process:
Turn on the unit
and wait 1 minute
Use DC voltmeter
to measure the
voltage on the two
ends of electrolytic
capacitor
Voltage higher than 200V?
Measure the AC voltage between
terminal L and N on wiring board
XT(power supply)
Voltage within
210VAC~250VAC?
Shut down the power and wait 20 minutes;or
use DC voltmeter to measure the voltage
on the two ends of capacitor , until
the voltage is lower than 20V
