Possible Cause
External Condensate Tank is
full. Condensate bypass jack
or condensate float switch
jack is not installed or not
positioned correctly. Water
level switch is engaged
Microprocessor board has
detected high water level in
the condensate pump.
Microprocessor board has
detected high pressure. The
High Pressure switch is
tripped.
Possible Solution
Empty External Tank (if
using). Make sure thank is
upright and level. Unplug
bypass plug or tank plug and
reinstall to assure good
connections. System
automatically resets when
fault condition is corrected.
Inspect condensate pump for
over flow and proper
operation, check condensate
line for a clog or crimping.
Resets automatically upon
fault correction, or call
1-800-KwiKool if the problem
persist.
High pressure is normally
caused by reduced
condenser air flow. In Cool
Mode check for restriction in
ducting. Check condenser
motors and/or blowers for
proper operation. In Heat
Mode be sure the service
door is closed, check the air
filter for blockage and be
sure that the return air flow
is unrestricted and the
supply air fan is operating.
High pressure is a manual
reset type. To reset, open
filter door. The button is
located above the filter.
Press button to reset (you
should feel a click).
