Open Circuit

Compressor has
an open circuit
due to power dis-
connection, fuse
is open or other
similar conditions.

Outdoor unit power disconnect is open.

Unit circuit breaker or fuse(s) is open.

Unit contactor has failed to close.

Check compressor contactor wiring and con-

nectors

Check for compressor contactor failure (burned,

pitted or open)

Check wiring and connectors between supply and

compressor

Check for low pilot voltage at compressor con-

tactor coil

High pressure switch is open and requires manual
reset.

Open circuit in compressor supply wiring or con-
nections.

Unusually long compressor protector reset time due
to extreme ambient temperature.

Compressor windings are damaged.

Check compressor motor winding resistance

Clears after one normal
compressor run cycle or
power reset.

6 Flashes
then
Pause

OFF

Open Start

Circuit

Current not
sensed by Start
transformer.

Run capacitor has failed.

Open circuit in compressor start wiring or connec-
tions.

Check wiring and connectors between supply and

the compressor

terminal

Compressor start winding is damaged.

Check compressor motor winding resistance

Clears when amperage is
detected in RUN and
START sensors, or after
power reset.

7 Flashes
then
Pause

OFF

Open Run

Circuit

Current not
sensed by run
transformer.

Open circuit in compressor start wiring or connections.

Check wiring and connectors between supply and

the compressor

terminal

Check compressor motor winding resistance

Clears when amperage is
detected in RUN and
START sensors, or after
power reset.

8 Flashes
then

Secondary

Low Voltage

24VAC is below
18VAC.

Control circuit transformer is overloaded

Low line voltage (contact utility if voltage at disconnect
is low).

Check wiring connections

Clears after voltage is higher
than 20VAC for two
seconds, or after power
reset.
