nents, refer to the appropriate section for your specific model. Only
those functions within the scope of normal maintenance are listed. This
manual cannot list all malfunctions that may occur, or corrective
actions. If a malfunction is not listed or is not corrected by listed correc-
tive actions, notify a qualified service center.
Cleaning
Cleaning Outside Surfaces
The most important cleaning task is to remove accumulations of dust, lint,
and grime that could interfere with proper air circulation and therefore effi-
cient heat transfer. The load surfaces, particularly on the inside, should be
checked periodically for possible collection of dust and lint.
