IMPORTANT:
Always
refer to the wiring dia-
grams that came with
your Thermolator to locate
specific electrical compo-
nents. Illustrations in the

Open the electrical enclosure door.
Turn the screw
on the front panel counterclockwise to open.
Mark or label each wire
connected to the mother-

wires to ensure they are con-
nected to the correct terminals
on the new motherboard.
Disconnect the wires
from the motherboard by
pulling the terminal
blocks up.
Loosen the screws hold-
ing the orange shield.
Remove the mother-
board and shield

electrical enclosure as a unit.
Remove the mother-
board from the shield
and replace with the new
motherboard.
Reattach the shield and
new motherboard
in the
electrical enclosure. Tighten
the screws.
Reconnect the terminal
blocks and wires to the
new board.
Make sure you align the terminal blocks with the correct
pins on the board. Push the terminal blocks onto the pins,
taking care not to bend any pins.
