Air Cleaner Temperature Sensor

  1. Temperature sensor should allow vacuum to close duct door at ambient temperatures below 75°F (24°C). Sensor should bleed off vacuum at certain temperature. This allows duct door to open to fresh air at specific temperature.
  2. Color code determines the temperature at which the vacuum bleeds off. Replace sensor if operating temperature is not within specification. See TEMPERATURE SENSOR SPECIFICATIONS.
