Thetford 6100 Series - Manual (Page 15)

Operating the refrigerator on the DC mode will override all other operating Modes
The DC mode design is to maintain an established temperature for short (4 to 6 hours) durations when gas or
AC is not available. The DC mode cannot be used for initial cooling. Only use while in transit.
(3-Way Models)
Start Up Instructions - Auto Mode
1. Move thermostat to COLDEST position. Set
AUTO-GAS switch to AUTO. Set DC OFF/DC
ON to DC OFF.
2. If 120 volts is available, Mode Control panel
will display AC, indicating refrigerator is operat-
ing in 120 volt AC mode.
3. If 120 volts AC is not available (power failure,
disconnected, etc.), Mode Control panel will
display LP, indicating refrigerator has automat-
ically switched to LP gas mode.
4. If Mode Control panel displays LP and a red X
continuously, the refrigerator has failed to ignite
burner on gas mode. Restart gas operation by
moving AUTO-GAS switch to the center posi-
tion and back to AUTO (See steps 3, 4, and 5
under Gas Mode.). Note: Unit operation will
automatically return to AC when 120 volts AC is
restored, even if the unit is locked out on gas
operation.
5. Move thermostat to desired setting, usually a
mid setting.
Start Up Instructions - Gas Mode
1. Move thermostat to COLDEST. Set AUTO-GAS
switch to GAS. Set DC OFF/DC ON to DC

2. Mode Control panel will display LP, indicating
LP gas mode (If LP is not displayed, check for
loss of DC supply voltage.). Initially, the red X
will be displayed for about 2 seconds; after
which, sparking will start at the burner and the
red X goes off.
3. After 10 seconds, the burner should be ignited
and operating normally.
4. On the initial refrigerator start-up, it may take
longer than 10 seconds to allow air to be purged
from the gas line. If gas does not ignite within 20
seconds, valve will automatically shut off and the
red X will be displayed at the CHECK position.
5. To restart when the X is displayed, move
AUTO-GAS switch to the center position then
return switch to the GAS position.
Note: If the gas does not ignite after
several attempts, contact your dealer or a
Norcold authorized service center,
