Utilizes ON/OFF of the limit switch when the motor turns.
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).
Some functions can force the swing flap into a fixed position, altough swing mode is selected on the
remote controller. This is not an 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 see "Fan and Flap Operations" on page 2-22 )
