The line fi lter helps to smooth out any fl uctuations in
voltage, protecting the control board and providing
more reliable operation. The line fi lter is installed
inside the cabinet and is attached to the right side
cabinet brace.
To check the line fi lter, look for the outer surface
to be burnt by heat or a power surge. The fi lter
resistance should be approximately 0
Ω
between
the black wire terminals and 0
Ω
between the white
wire terminals.
