NOTE: It is not necessary to remove the top cover to gain
access. Removing the top cover may cause grill panels,
corner posts or coils to be damaged. It is recommended to
protect the top cover from damage of tools, belt buckles,
etc. while servicing from the top.
1. Should the unit height allow components to be
accessed from the top of the unit, follow procedures
for removing fan motor assembly. Access
components through the top cap.
2. Large components may not be removed easily
without having access from the top and side. Side
access may allow procedures such as brazing,
cutting, and removal easier. Follow procedures below:
a. Follow procedures to remove the fan motor assembly.
b. Air conditioning units only, remove the screws from the
top of the electrical control panel. (Heat pumps will not
have screws holding the electrical control panel in
place at the top once the control box cover has been
removed.)
c. Remove the base pan screws holding the control panel
and lift off the unit.
Certain maintenance routines and repairs require removal of
cabinet panels.
