Capacitor Charging Malfunction - Toyotomi GAN-A135GVR-T3 Service Manual

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 20n muties; 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
panel AP1
End
Fault with the voltage
testing circuit on
Y
control panel AP1
Shut down the power
and repair the power
supply to restore the
N
range
210VAC~250VAC
Connect the reactor
Laccording to
N
Electrical Wiring
Diagram correctly
Replace the control
panel AP1
power on and
If the fault is
restart the unit
eliminated?
