Solution
Check for 12VDC; display is blank
when 12V is not present.
Verify that the 12VDC is present;
the unit will not operate when the
voltage is below 10.5V.
Verify that 115VAC is present.
WITH POWER REMOVED, verify
that nothing is obstructing the fan
blade, that it spins freely.
Check the 5 amp Fuse on the board
Check Fan Mode. If set to FAN ON,
the fan will run continuously.
Verify proper installation per
installation instructions (pg. 5 ...
not on exterior wall or in direct
a vent or duct...)
This is normal, there is a 3
minute OFF timer preventing the
compressor from being turned OFF
and right back ON.
In Heat-Pump mode, if Auto Fan is
selected, the fan will not turn ON
until the compressor turns ON after
the 3 minute OFF timer.
With a Cool Only model, check that
DIP Switch #1 on the back side of
the wall thermostat is turned OFF.
(see Wiring Diagram)
With a Heat-Pump model, check
to see if the outdoor temperature
sensor is unplugged or damaged.
