Replacement of the damper motor
The damper motor keeps the damper in the right position according to the signals from the control
board. This is done in order to use the ambient air for cooling.
When to replace
The damper motor only needs to be replaced when it is faulty. The typical faulty would be that the
damper does not move at all.
Before you start
Before you start make sure that you have the following available:
A Torx 20 screwdriver
A 7# spanner
A new damper motor, see “spare parts” for details
Caution
Only trained or certified technicians are allowed to carry out the replacement of parts. Remember that
all power to the unit must be switched off or disconnected before start any service work on the unit.
