2. Open the valve on the propane tank.
3. Turn the thermostat to its coldest or highest setting.
4. Turn the selector switch on the control panel to the gas position
5. Push and hold the safety valve button in the fully depressed position. (NOTE - This "safety
valve" only allows gas to flow when there is a flame present or when the button is pressed. Any
loss of flame as sensed by the thermocouple closes the safety valve and stops the flow of gas.
The button that you push in and hold from the control panel actually bypasses this safety
function and causes gas to flow as long as you hold in on the button.)
6. In rapid succession, push the igniter button several times for about 5 seconds.
7. While the person on the inside continues to hold in the safety valve button, the second person
who is trying to observe the flame inside the burner box should be able to see a bright blue flame
at the end of the burner orifice tube.

Results of Troubleshooting :

After performing these steps, you may find one of three results.
A. No flame at all. Double check to make sure the valve on the propane tank is open and that the
manual valve on the back of the refrigerator is also open. This manual valve should always
remain in the ON position. If you can smell propane but there still is no flame, then you probably
have a faulty igniter, or the burner orifice can be fully clogged and needs to be cleaned.
B. Flame present but it is yellow instead of blue or flickers erratically. You probably have a
clogged burner orifice tube which needs to be removed and cleaned.
C. Flame is deep blue in color: This indicates that the burner orifice is OK. So far, so good.
Photo #3 shows the deep blue flame touching the tip of the thermocouple and the end of the
igniter is glowing red.
