FUNCTION

SPECIFICATIONS.
SYMPTOM
Opening the HPCO will cause the control board to
initiate a 10 minute delay. The display counts down
from 10 minutes to 0 minutes, at which point the ice
machine attempts a restart. If the HPCO is closed the
ice machine will continue to run. If the HPCO remains
open after the 10 minute delay or reopens when the
compressor starts, the ice machine will start another
10 minute delay period. The ice machine will lockout
after 10 failed attempts.
