33 - Oxygen Sensor/ Fuel Cell

The oxygen sensor (Figures 23, 26, and 29) is located in the partition wall between the electronics compartment and the filter/ fans compartment. It senses the concentration of oxygen in the filter/fans compartment and sends this information to the oxygen concentration meter for display.

The fuel cell powers the black calibration needle in the oxygen concentration meter. The cell has an average life of about one year, depending on frequency of use. Difficulty in moving the black calibration needle is usually an indication of an exhausted fuel cell. Order replacements from SSCI, Part Number 853396. For information on replacing the fuel cell, refer to Replacing the Fuel Cell on Page 68.

CAUTION: Before handling the fuel cell, please read Fuel Cell Warnings on Page 4.
