MOTOR BOARD REPLACEMENT
When replacing or testing electronic components, be sure to wear a static strap
that is connected to a chassis ground. This protects the electronic components
from any static charge while working on the unit.
The motor board is located in the E-Box, to the right of the control board. It is
mounted to the panel on three (3) plastic mounting studs and a threaded stand-
off, shown in Figure 55.
