Monitor Compressor Run Duration, Displays If Service is Needed
The microprocessor observes the changing state of the compressor relays on the control board to determine the
length of compressor run time (See Figure 3-50). Other than during initial pull down, if a compressor runs 100%
(Freezer = 6 hours / Refrigerator = 4 hours), five consecutive times, a fault code is logged, defrost is initiated, and
the service icon will flash. If approximately twenty-four (24) hours worth of 100% run periods occur, and the com-
partment temperature does not fall to at least the average of the set point and low off-set temperature (and the door
is not opened during the last run period), then the service icon will flash and the alarm will chime (See Figure 3-51).
NOTES:
• If the unit is ever switched OFF then back ON, compressors will not energize for at least three (3) minutes. This
minimum OFF time is used to protect the compressor and its electricals.
• To clear error indicators and Fault Codes the problem must be corrected, then press the ALARM key for fifteen
(15) seconds. Failure to clear Fault Codes will result in the highest priority error indicator reappearing in the LCD
when the unit is
switched back ON.
