TEST PROCEDURE/ACTION
Check to make sure that it is not on the 7
minute delay. Ohm the compressor. The
compressor should be 6 to 7 Ω. If no resis-
tance is present, replace compressor.
See "Inverter" section to check the inverter.
If a mechanical clanking noise is evident,
replace the compressor. If the consumer is
complaining about varying sound level, ex-
plain the variable speed operation of the
compressor to them.
Run control diagnostics to check condenser
fan operation in step 4. The condenser fan
runs independently of the compressor but is
a constant speed DC motor. Voltage is sup-
plied to the condenser fan by a relay on
main control board. Voltage should be
present at pin 1 of connector 6 of the main
control board during operation (see the dia-
gram on page 7-2).
Check for blade hits. Check the mounting
system.
Change to a colder temperature setting. A
mid point setting will deliver approximately
37°F in the RC, and 0°F in the FC in most
usage and ambient conditions.
Change to a warmer temperature setting. A
mid point setting will deliver approximately
37°F in the RC and 0°F in the FC in most
usage and ambient conditions.
If either door is open for more than ten min-
utes, the control will turn off the light circuit.
This includes the control user interface in
the RC. The user interface is powered down
when the RC door is closed and is inactive.
The Door Open indicator light will flash and
an audio alarm will sound. The probable
cause is a failure of the light switch actuator
to cause the switch to change position.
The actuating mechanism of the light switch
is attached directly to the top door hinge pin.
If the door is set low the actuator blade my
not contact the rocker style light switch. The
quickest repair is to raise the affected door
until the mechanism operates properly. Align
the second door to match the first. Make
sure the metal is clean.
