Why my Inficon Security Sensors unit turns on, but does not detect refrigerant?
- J
  James BensonAug 18, 2025
  There are several reasons why your Inficon Security Sensors unit might not be detecting refrigerant: * The unit may not have completed warm-up. Allow 45 to 90 seconds for warm-up to complete. * The filter could be clogged. Replace the filter cartridge. * The pump may have failed. Listen for the pump sound; if there's no sound and the battery is charged, contact INFICON. * The sensitivity might be set too low (Pinpoint mode only). Verify the sensitivity level, using High or Super for small leaks. * The incorrect sensor might be installed. Ensure the correct sensor (refrigerant or CO sensor) is being used.

  There could be several reasons why your Inficon Security Sensors unit isn't detecting refrigerant: 1. The unit may not have completed its warm-up cycle, which takes 45 to 90 seconds. Wait for the warm-up to complete. 2. The filter might be clogged, restricting airflow. Replace the filter cartridge. 3. The pump may have failed. Listen for the pump sound; if there's no sound and the battery is charged, contact INFICON. 4. The sensitivity might be set too low in Pinpoint mode. Verify the sensitivity level, and use High or Super for very small leaks. 5. The incorrect sensor might be installed. Ensure that the correct sensor (refrigerant sensor or CO sensor) is being used.

  If the power indicator on your Inficon Security Sensors unit is quickly flashing red, it indicates a battery error. This can occur due to a failed battery, improper battery installation, or a poor connection. Try removing and reinstalling the battery. If the problem persists, replace the battery. Another cause might be that the battery is outside the ideal temperature range. Allow the battery to return to normal temperature.
