Microprocessor has
detected freezing on the
evaporator coil if the system
has a factory installed freeze
sensor. (Special order)
Check for freezing on the
evaporator coil and turn the
system off to let it thaw out,
call 1-800-KwiKool if your
system is not equipped with
a freeze sensor. Auto resets
upon correction.
System is ON and display is
showing ON but unit is not
supplying conditioned air.
System is in time out (F or
C is flashing), set point is

Fault Possible Cause Possible Solution
System is ON but the
microprocessor board
resets the time delay
(flashing F or C) when the
compressor attempts to
start.
Microprocessor board
detects voltage drop below
operating parameters.
Confirm the integrity of
your source power, check
for proper wire size and
length of power extension
cable. Be sure the circuit is
dedicated to only the
operation of your KwiKool.
Power is supplied but
control is blank
Low voltage circuit is not
engaged
Check source power
breaker and verify incoming
power to connector. Call
