7) Freeze Cycle "GM" and "COMP" LED are on: The 5-min. ice purge timer terminates or
the ice purge cycle bypass button ("SERVICE") is pressed, "COMP" LED turns on.
To bypass the 5-min. Ice Purge Cycle, press the "SERVICE" button on CB after the "GM"
LED turns on. WARNING! Risk of electric shock. Care should be taken not to touch
live terminals. 115VAC is present between CB X1 relay power supply brown (BR) and
neutral (W) at all times. If not, check 115VAC power supply wire connections from power
switch. If "COMP" LED is not on after 5-min. ice purge timer terminates, replace CB.
When "COMP" LED turns on, PDS energizes. If "COMP" LED is on and PDS does not
energize, check for 115VAC between CB X1 relay dark blue (DBU) wire and a neutral
(W). If 115VAC is not present, confirm X1 relay brown (BR) to a neutral (W). If 115VAC is
present on X1 relay brown (BR) and not on X1 relay dark blue (DBU), replace CB.
