Diagnose method (Diagnose according to 6 LEDs lighting status.)
(1) When all the LEDs are lit uniformly, the compressor is defective.
→
Replace the compressor.
(2) When the LEDs are not lit uniformly, check the power module.
→
Refer to
Check No.13
.
(3) If NG in
Check No.13
, replace the power module (PCB).
If OK in
Check No.13
, check if there is any solder cracking on the PCB.
(4) If any solder cracking is found, replace the PCB or repair the soldered section.
If there is no solder cracking, replace the PCB.
Caution
(1) When the output frequency is low, the LEDs blink slowly. As the output frequency increases,
the LEDs blink quicker. (The LEDs look like they are lit.)
(2) On completion of diagnose by the inverter checker, be sure to re-crimp the FASTON
terminals. Otherwise, the terminals may be burned due to loosening.
