    How to fix POWER lamp (green) if it does not come on for Cosmos Gas Detectors?
    • C
      Christy SmithAug 9, 2025
      If the POWER lamp (green) does not come on when you turn on your Cosmos Gas Detectors, there are several potential causes. Ensure that the power switch on both the base unit and the main unit are turned ON. Check the wiring to make sure it is properly connected, and tighten the terminal connections if needed. Also, verify that the connector harness is correctly attached. If none of these steps work, the fuse may have blown, and you should replace it.

    Why is the TROUBLE lamp (yellow) blinking on my Cosmos Gas Detectors?
    • H
      Haley BoothNov 2, 2025
      If the TROUBLE lamp (yellow) is blinking on your Cosmos Gas Detectors, it could be due to several reasons. First, the filter element might be clogged, in which case you should replace it. Alternatively, the pump may be defective, requiring you to replace the pump unit. A blocked gas sampling pipe could also be the cause; remove the blockage to resolve this. Ensure the connector harness is properly connected by checking and reattaching it if necessary. A sensor with incorrect settings may have been inserted; adjust the settings on the main unit or replace the sensor. A defective sensor unit should be replaced. Ensure the sensor unit is correctly installed. Finally, if the flow sensor output was unstable when the power was turned on, leave the power on for about 30 minutes to allow it to sta...
