Main Circuit Short Check

Warning: Ensure the voltage between (+) and (–) of the diode bridge (DB1) is approximately 0 V before checking.

Enter the voltage between (+) and (–) of the diode bridge (DB1)

Measure the resistance between the pins of the DB1.

Enter the resistance between the pins of the DB1

Is the resistance ∞ or less than 1 kΩ?

If the resistance is ∞ or less than 1 kΩ, short circuit occurs on the main circuit.

Sign off on the main circuit short check

Run this procedure

Power Module Check

Warning: Ensure the voltage between (+) and (-) of the power module is approximately 0 V before proceeding.

Voltage between (+) and (-) of the power module is approximately 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 successfully disconnected?

Measure resistance between the (+) or (-) terminal of the power module and the U, V, or W terminal of the compressor with a multimeter.

Enter the resistance measurement

Evaluate the measurement results

Inverter Analyzer Check

Characteristics: Inverter analyzer: RSUK0917C

Warning: Be sure to turn the power off before starting the procedure.

Power turned off?

Install an inverter analyzer instead of a compressor.

Inverter analyzer installed?

Note: Make sure the charged voltage of the built-in smoothing electrolytic capacitor drops to 10 VDC or below before carrying out the service work.

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

Remove the terminals from the compressor.

Terminals removed from the compressor?

Rotation Pulse Check

Check No.16:

20/25/35 class

1. Check that the control voltage between the pins 10 - 11 is 15 VDC.

2. Check if the Hall IC generates the rotation pulse (0 ~ 15 VDC) 4 times between the pins 10 - 12, 10 - 13, when the fan motor i/s manually rotated once.

50 class

Make sure that the voltage of 320 ± 30 V is applied.

1. Set operation off and power off. Disconnect the connector S70.

2. Check that the voltage between the pins 4 - 7 is 320 VDC.

3. Check that the control voltage between the pins 3 - 4 is 15 VDC.

Run this procedure

Power Supply Waveforms Check

Check No.11

Measure the power supply waveform between No. 1 and No. 2 on the terminal board

Check if the power supply waveform is a sine wave (Fig.1)

Check if there is waveform disturbance near the zero-cross (sections circled in Fig.2)

Upload a photo of the waveform
