The control assembly is the lower section of the furnace.
It houses all the P.C. boards, relays, the balance, and
wire assemblies. When the front control panel (keypad)
is lowered, you can look into the electronic control hous-
ing. The control assembly, if properly disconnected, can
be slid out of the back of the unit.

the back. They are located from the lower left-
hand corner, across the top of the control sec-
tion, and the lower right-hand corner of the unit.
