Capacitor Voltage Check

Warning: This procedure requires trained personnel with PPE!

Main circuit checked for short circuit?

Warning: Never touch any live parts during the procedure.

Voltage between FU2 and DC–

Is the voltage 50 V or less?

Ensure firm contact between the multimeter probes and the test points.

Sign off on the capacitor voltage check

Run this procedure

Electronic Expansion Valve Check

EV connector correctly inserted in the PCB

All EVs generate a latching sound after power cycle

Continuity check for EVs not generating a latching sound

Outdoor unit PCB check if no EV generates a latching sound

EV unit check after mounting a good coil

Warning: Operating with a defective electronic expansion valve may cause problems

Run this procedure

Hall IC Check

CDXS, FDXS Series

1. Check the connector connection.

2. With the power on, operation off, and the connector connected, check the following.

(1) Output voltage of about 5 V between pins 1 and 3.

(2) Generation of 3 pulses between pins 2 and 3 when the indoor fan motor is operating.

If NG in step (1) -> Defective PCB -> Replace the PCB (control PCB).

If NG in step (2) -> Defective Hall IC -> Replace the indoor fan motor.

If OK in both steps (1) and (2) -> Replace the PCB (control PCB).;

Run this procedure

Indoor Fan Motor Connector Check

CTXG, FTXR, CTXS, FTXS, FVXS Series

1. Check the connection of connector.

2. Check motor power supply voltage output (pins 4 - 7).

3. Check motor control voltage (pins 4 - 3).

4. Check rotation command voltage output (pins 4 - 2).

5. Check rotation pulse input (pins 4 - 1).

FDMQ Series

1. Turn the power supply OFF.

2. With the fan motor connector disconnected, measure the resistance between each pin, then make sure that the resistance is more than the value mentioned in the following table.

Run this procedure

Inverter Analyzer Check

Warning: This procedure requires trained personnel with PPE!

Power turned off?

Install an inverter analyzer instead of a compressor.

Charged voltage of the built-in smoothing electrolytic capacitor dropped to 10 VDC or below?

Terminals removed from the compressor?

Terminals connected to the terminals of the inverter analyzer without touching each other?

Activate the power transistor test operation from the outdoor unit.

Forced cooling operation ON/OFF switch pressed for 5 seconds?

Diagnose according to 6 LEDs lighting status.

Run this procedure
