Troubleshooting (Continued)
Problem
Possible Cause
Water is leaking from condensate line at
indoor unit.
Check condensate line outside to make sure it is
not obstructed.
Check condensate line to make sure it has not
been disconnected from indoor unit.
Water is leaking from the outdoor unit.
During operation in high−humidity areas, conden-
sate will form on cold outdoor refrigerant pipes.
When heat pump is operating in defrost mode, ice
will thaw from around outdoor coil and water will
flow from the unit.
Clicking noise heard inside.
Sometimes, the sound of the outdoor unit fan or
compressor relay can be transmitted in a way that
makes it seem to be coming from the indoor unit.
Indoor fan is not working.
Heat pump units −− In HEAT mode, a timed delay
keeps indoor fan off for two minutes to prevent
unheated air from being circulated by the indoor
fan.
Heat pump units −− In HEAT mode, cold outdoor
temperatures and high humidity cause frost to ac-
cumulate on the outdoor unit. When this happens,
the unit will enter a defrost cycle. The indoor fan is
off during the 3 − 12 minute cycle.
In DEHUMIDIFICATION mode, indoor fan opera-
tion may be stopped to avoid delivery of moist air
to the room. Do not adjust temperature setting.
Error Codes
If a problem occurs with the system, an error code will replace the temperature setting displayed on
the front cover of the indoor unit. If more than one error has occurred, the codes will alternate so
that all codes are shown. Make note of the code (E4, F6, H4, etc.), then reset the display by pressing
the ON/OFF button on the wireless remote. Press the ON/OFF button a second time to reapply pow-
er to system. If code is still displayed, disconnect and restore power at the unit disconnect switch
or circuit breaker. If the problem was temporary, the code will not reappear. If the error code re−ap-
pears after power has been broken and restored at the disconnect switch or circuit breaker, call a
licensed professional service technician.
