Error Decision
Conditions
When ON/OFF of the micro-switch for positioning cannot be reversed even through the swing
flap motor for a specified amount of time (about 30 seconds).
Remark Some functions can force the swing flap into a fixed position, although swing mode is selected
on the remote controller. This is not a unit error, but a control function to prevent draft to the
customer.
Before starting the troubleshooting, make sure the swing flap is not forced into such a fixed
position. (e.g. Hot start, defrost operation, thermostat OFF in heating operation or freeze
prevention in cooling operation. For details refer to "Swing Pattern Selection" on P.33.)
