Function check
Check that the drum is empty and the loading door is closed.
Checking the micro switches
Start the dryer.
Check if the micro switches are working properly:
• The dryer must stop if the loading door is opened.
If the dryer operates with the loading door open, go to section 29.
• The dryer must stop when the lint drawer is opened.
If the dryer operates with the lint drawer open, go to section 29.
Correct direction of rotation
For dryers with a 3-phased motor the direction of rotation must be checked.
Check the direction of rotation of the blower motor:
1. Fig. 1 Correct direction of rotation must be clockwise when viewed through the
ventillation holes on the motor cover on the rear of the dryer.
If the direction of rotation is not correct, swap two phases on the power input
connection terminal block.
Final test
1. Start the dryer and allow it to operate for 5 minutes on a program that requires
heat.
2. Check whether the heating is working by opening the loading door and feeling
the heat.
If the above test-points are in order, the dryer is ready for use.
