-6- Inverter

Replace only the compressor if only the compressor is found to be defective.

Replace only the fan motor if only the fan motor is found to be defective.

Replace the defective components if the inverter is found to be defective.

If both the compressor and the inverter are found to be defective, replace the defective component(s) of both devices.

(1) Inverter-related problems: Troubleshooting and remedies

1) The INV board has a large-capacity electrolytic capacitor, in which residual voltage remains even after the main power is

turned off, posing a risk of electric shock. Before inspecting the inside of the control box, turn off the power, keep the unit off
for at least 10 minutes, and confirm that the voltage between FT-P and FT-N on INV Board has dropped to DC20V or less.
(It takes about 10 minutes to discharge electricity after the power supply is turn off.)

2) The IPM on the inverter becomes damaged if there are loose screws are connectors. If a problem occurs after replacing some

of the parts, mixed up wiring is often the cause of the problem. Check for proper connection of the wiring, screws, connectors,
and Faston terminals.

3) To avoid damage to the circuit board, do not connect or disconnect the inverter-related connectors with the main power turned

on.

4) Faston terminals have a locking function. Make sure the terminals are securely locked in place after insertion.

5) When the IPM or IGBT is replaced, apply a thin layer of heat radiation grease that is supplied evenly to these parts. Wipe off

any grease that may get on the wiring terminal to avoid terminal contact failure.

6) Faulty wiring to the compressor damages the compressor. Connect the wiring in the correct phase sequence.

Press the tab on the terminals to remove them.
