OFF Open Circuit
Compressor has
an open circuit
due to power dis-
connection, fuse
is open or other
similar conditions.
1
Outdoor unit power disconnect is open.
2
Unit circuit breaker or fuse(s) is open.
3
Unit contactor has failed to close.
S Check compressor contactor wiring and con-
nectors
S Check for compressor contactor failure (burned,
pitted or open)
S Check wiring and connectors between supply and
compressor
S Check for low pilot voltage at compressor con-
tactor coil
4
High pressure switch is open and requires manual
reset.
5
Open circuit in compressor supply wiring or con-
nections.
6
