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.
Tobypass 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) or black (BK) wire 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, CR (if applicable) and compressor energize. If "COMP"
LED is on and compressor relay (CR) (if applicable) and compressor are not, check for
115VAC from CB X1 relay power supply brown (BR) or black (BK) wire to neutral (W).
If 115VAC is present, check X1 relay red (R), violet (V), or brown (BR)(FD-650 only) to
neutral (W). If 115VAC is present on X1 relay brown (BR) or black (BK) and not on X1
relay red (R), violet (V), or brown (BR)(FD-650 only), replace CB.
8) Rell "WTRIN" LED is on: See "5) Fill "WTRIN" LED is on:" above.
