Check of power supply
M
Inverter does not work.
Check of rush current limiting circuit
N
Outdoor unit does not operate.
Replace the current limiting resistor (R64).
When the current limiting resistor is open, the rush current limiting relay may not be working properly.
Therefore confirm the limiting resistor works properly after replacing it.
Does current limiting resistor (R64) detect 10

Is there 208-230V AC between
terminal block L1 and L2 on
the outdoor unit?
Turn on power supply.
Check the connecting of main circuit part, and connector.
Is there 290-330V DC to
smoothing capacitor (C61)?
Replace the outdoor electronic
control P.C. board.
Check the power supply cable.
Is there 208-230V AC between
terminal TAB69 and X64 (terminal 4)?
Check the main circuit parts
and replace it.
