Capacitor Voltage Check

Warning: Check the main circuit for short circuit before proceeding

Main circuit checked for short circuit?

Warning: Be careful never to touch any live parts.

Voltage reading of the capacitor

Sign off on the voltage check

Run this procedure

Electronic Expansion Valve Check

Warning: This check requires trained personnel with PPE!

EV connector correctly connected to the PCB

Did the EV generate latching sound after power cycle?

Continuity confirmed when connector disconnected and tested with a tester

Check the continuity between the pins

EV coil faulty if no continuity between the pins

Outdoor unit PCB faulty if continuity confirmed

Note: The latching sound varies depending on the valve type.

Run this procedure

Fan Motor Connector Output Check

Check the connection of connector

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

Check the motor control voltage (pins 4 - 3)

Check the rotation command voltage (pins 4 - 2)

Check the rotation pulse (pins 4 - 1)

Sign off on the fan motor connector output check

Run this procedure

Inverter Checker Check

Warning: This procedure involves high voltage. Only trained personnel should perform it.

Power turned off

Install the inverter checker instead of a compressor

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 checker

Warning: Do not touch the terminals (U,V,W) each other. High voltage is applied.

Power transistor test operation activated from the outdoor unit

Diagnose according to 6 LEDs lighting status

Run this procedure

Power Module Check

Check No.22

Note: Check to make sure that the voltage between (+) and (–) of the diode bridge (DB1) is approx. 0 V before checking.

Voltage between (+) and (–) of the diode bridge (DB1) is approx. 0 V

Disconnect the compressor harness connector from the outdoor unit PCB. To disengage the connector, press the protrusion on the connector.

Compressor harness connector disconnected from the outdoor unit PCB

Follow the procedure below to measure resistance between the terminals of the DB1 and the terminals of the compressor with a multi-tester. Evaluate the measurement results for a judgment.

Enter the resistance between the terminals of the DB1 and the terminals of the compressor

Resistance measurement within acceptable range

Sign off on the power module check

Run this procedure
