Section 2 - LP Gas Ignition Failure - Initial Refrigerator Start-Up & LP Gas Re-Ignition
Corrective Action
1. Has LP gas tank been filled recently? Purge gas line to refrigerator.
2. Is LP gas tank valve on? Turn valve on.
3. Is refrigerator's manual shut-off valve on? Turn manual valve on.
4. Is LP Gas supply pressure to the refrigerator at 11" water column?
5. Check input DC supply voltage to refrigerator's power board. Correct if DC voltage below 10.5 VDC or above 15.4 VDC
6. Secure ignition wire connection at power board if necessary.
7. Secure wire connections from power board to gas valve if necessary.
8. If ignition wire is damaged, replace ignition/sense electrode assembly
9. Does the sense/electrode wire have continuity? Replace if no continuity found.
10. Check the sense/ignition wire for short to ground. Any reading, replace sense/ignition wire.
11. Measure DC voltage across the terminals of the gas valve during the trial for ignition. If the voltage is between
10.5 to 15.4 VDC and an audible click is not heard from the valve during trial for ignition, replace the gas valve.
If the DC voltage is not being supplied to the gas valve, replace the power board.
12. Inspect the burner flame to verify that it has a sharp blue and stable appearance. If there is a constant yellow component
observed or if the flame appears erratic or unstable (roaring), the burner, orifice, and the cooling unit's flue must be
cleaned.
13. Check the alignment of the electrode for the correct spark gap. The electrode tip is to be positioned between 1/8" - 3/16"
from the top of the burner.
Section 3 - Fresh Food Compartment Door Ajar
Corrective Action
1. Close the door to turn off the alarm, flashing backlight and bell, and to remove code.
2. If the light is on with door closed, use a magnetic screwdriver and move it diagonally across the
bottom of the Control Box Assembly.
3. If the code disappears, alarm ceases, and the flashing backlight and bell ceases, the magnet in the
door is defective. Replace lower door.
4. If the code remains, the alarm sounds and the flashing backlight and bell remain active, replace
the Control Box Assembly.
Section 4 - AC Mode Selected, AC Power Not Available
Corrective Actions
1. Check vehicle AC fuse or circuit breaker. Replace fuse if blown or reset circuit breaker if tripped.
2. Check input AC supply voltage to receptacle into which refrigerator is plugged. Correct power source to
receptacle. AC voltage must be between 108 VAC min.-132 VAC max.
3. Check input AC supply voltage to refrigerator's power board. Disconnect AC power cord from power board.
Measure AC voltage at the terminal end of the AC power cord. If AC voltage not available, replace
power cord
4. Insure AC fuse holder compresses fuse. Tighten fuse holder clips if necessary.
5. Check refrigerator's AC fuse (5 Amp). Replace if blown.
