TROUBLESHOOTING

Replace the cables.

Remove the cables from the main PCB

and check PIN No.1-3 of CN43 for

DC 12V.

Is DC 12V generated?

Connect the cables and check

PIN No.1-3 of CON1 on the CO2 Sensor

Connector for DC 12V.

Replace the CO2 Sensor

Is DC 12V generated?

Replace the MAIN PCB.

Yes

CO2 level is not displayed on the MAIN PCB

O “0” is displayed on the MAIN PCB.

W TROUBLESHOOTING (Continued)

The error in the CO2 Sensor is only detected after 2 minutes when powered on.

The operation test needs to last longer than 2 minutes to be valid.

Caution

Replace the MAIN PCB.
