2. Touch and hold the ON/OFF button ( ) for one (1) second to
turn the refrigerator off.
3. Open the lower intake vent.
4. Disconnect the two (2) white wires from the gas train assembly

To avoid possible propane gas leaks,
always use two (2) wrenches to loosen
and tighten the gas supply line at the gas
train assembly.

6. Remove the two (2) screws (Fig. 11, B) that attach the gas
train support bracket/door assembly (Fig. 11, C) to the cooling
unit.
Never attempt to operate the gas train
when it is NOT installed in the cooling unit
because of the risk of electrical shock.
7. Remove the gas train assembly from the cooling unit.
When cleaning, do not try to remove
the burner. Removal may can cause a
propane gas leak. Leaking propane gas
can ignite or explode and result in danger-
ous personal injury or death. Do not try to
clean the burner with anything other than
compressed air.
