no AC
Meaning:
The Power Board sensed the refrigerators AC input voltage to be
less than 85 volts. This fault, by itself, can only be displayed while
operating in the Manual AC Mode. This fault can be displayed in
conjunction with other faults while operating in the Auto Mode. For
example; no AC followed by no FL (See AUTO mode discussion for
further explanation).
Verify:
■ The refrigerator is plugged into a known working AC outlet sup-
plying a minimum of 85 VAC.
■ The AC power cord is in good operating condition.
■ The glass 8-amp fuse (F2) on the Power Board is intact.
■ The (F2) fuse holder clips are not loose or broken.
■ If above steps all check good, replace power board.

Fault Codes, cont’d.
no FL
Meaning:
The Power Board was not able to detect a ame present at the
burner. This fault, by itself, can only be displayed while operating in
the Manual Gas Mode. This fault can be displayed in conjunction
with other faults while operating in the Auto Mode. For example; no
AC followed by no FL.
Verify:
■ All propane gas shutoff valves (including manual shutoff on gas
valve itself) are open.
■ Propane Gas pressure at refrigerator is 10.5 in. W.C - 11.5 in.
W.C. (water column).
■ Propane gas supply line is free of air.
■ The burner is clean.
■ The electrode-to-burner air gap is between 1/8” and 3/16”.
■ The spark-sense igniter wire is installed correctly and in good
operating condition.
■ Gas valve solenoid is in good operating condition (Coil resis-
tance ≈ 74 Ohms to 92 Ohms).
■ Wires to the gas valve are connected and in good operating
condition.
■ Power Board supplies 12 VDC to gas valve when required.
■ If the above steps all check good, replace power board.

The gas valve is “mechanically” stuck open and subsequently the
Power Board has sensed a ame present when there should not
be. This fault can be displayed in ANY MODE.
■ Replace the gas valve.
