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?
N
Measure the AC voltage between
terminal L and N on wiring board
XT(power supply)
Voltage within
210VAC~250VAC?
Y
Shut down the power and wait 20 mi nutes; or
use DC voltmeter to measure the voltage
on the two ends of capacitor (test3), until
the voltage is lower than 20V
Check the
connection of reactor
(L in the Electrical
Wiring Diagram)
If the wiring of
reactor L is normal?
Y
Replace the control
