Manual Mode

Press and hold MODE until the AUTO LED goes out and the desired operating mode lights. Unlike AUTO mode,

the operating mode LED stays lit until an alternate mode is selected. If the energy source is interrupted in MANUAL
mode, the corresponding LED flashes, and the refrigerator stops operating until an alternate energy source is
selected or the problem is corrected. See Diagnostics for corrective actions.

AUTO and MANUAL Modes - Gas Operation Only

If gas does not ignite within 30 seconds, the refrigerator’s gas valve automatically closes and the operating

controls select an alternate energy source (AUTO Mode) or revert to a stand-by mode where the LP GAS LED
flashes. The LED flashes until the refrigerator is turned OFF and then ON. If gas does not ignite after several
attempts, check input gas supply, or consult your dealer or a Norcold authorized service center. Select a different
operating mode by pressing and holding MODE. The refrigerator does not switch to the new operating mode until
you release MODE.

Backup Operating System (BOS)

This refrigerator has a Back-Up Operating System to allow the refrigerator to cool in case of a failure within the

temperature sensing circuit. If this happens, the TEMP SET LED flashes and refrigerator switches to BOS mode.
This mode provides cooling until the refrigerator is serviced. Check refrigerator temperatures when operating in
this mode. If the temperature is too cold, adjust the thermostat to the left in single LED steps. If the temperature
is too warm, adjust the thermostat to the right in single LED steps. Allow the refrigerator to operate at the new
setting for one hour before rechecking the temperatures (frequent door opening prevents the temperatures from
stabilizing). While the refrigerator can operate in this mode, Norcold recommends that you seek service as soon
as practical to restore normal operation.
