6.2 Replacing the Temperature Probe or High Limit Thermostat
A. Disconnect the unit from the electrical power source.
B. Turn the unit on its side. Remove the five screws from the chassis bottom.
C. Set the unit down on its base.
D. Carefully lift the cowl assembly upward until it is clear of the blower assembly, then
lay it on the table behind unit.
E. The air tower has two sections – a removable front section and the fixed rear section.
The front section must be removed to access the temperature probe and high limit
thermostat. A pair of slotted brackets, one at each end, holds the front section in place.
Insert a
5 ⁄
16
-inch nut driver through the air outlet opening and turn the nuts on the
outside studs counterclockwise to loosen them. Do not remove the nuts.
F. Grasp the bottom flange of the tower and push upward while rotating the bottom
outward to disengage the two slotted brackets on the front section from the studs on the
rear section.
G. Cut the leads of the failed component near the component.
H. If replacing the temperature probe, unplug the probe connector from the controller
board., but leave the leads in place for now.
I. Remove the failed component from its mounting and install the replacement component
in its place.
J. Securely connect the leads from the new component to the old leads cut in Step G on
the air tower side of the unit. Grasp the old leads at the opposite end and gently pull
them through the unit. NOTE: It is easier to pull one lead through at a time.
If the leads become disconnected while pulling them through, it will be necessary to
remove the plate. Refer to Steps G through J in procedure 6.3 below.
K. Once the new wires have been pulled through, replace the terminals cut off in Step J.
L.
If replacing the temperature probe, use a pin pusher to disconnect the old leads from the
plug and connect the new wires. Reconnect the plug to the controller board.
M. If replacing the high limit, connect the leads as shown in the wiring diagram (polarity
does not matter).
N. Reassemble the unit by reversing Steps A through F.
