POSSIBLE 700-2 BASE UNIT ERROR INDICATORS
This page contains diagrams illustrating what customers may see on the LCD if a problem/error exists with the unit.
(For Model 700BR-2, see Figures 3-89 through 3-93. For Model 700BF/I-2, see Figures 3-92 through 3-94.)
NOTE: A blinking “SERVICE” annunciator in a base unit indicates thermistor faults only
. Unlike the tall units, the
blinking “SERVICE” annunciator cannot indicate excessive compressor run, because the length of compressor run-
time is not monitored on base units.
NOTE: Unlike the 700-2 tall units, the “SERVICE” and “ICE” annunciators on the LCD of a 700BFI-2 will not blink,
and the ice making system will not be disabled, if the water valve is energized for more than 15 seconds.
NOTE: To clear thermistor error indicators, the problem must be corrected.
