4. Testing and replacing the temperature control.

Unplug the unit and remove the temperature control knob. Remove the screws securing the

fan shroud to the evaporator coil assembly, next remove the screws securing the

temperature control to the fan shroud. Taking care not to bend the capillary line, pull

off the wire connectors. Now you are ready to test for continuity.

Set your multimeter at RX1, Touch a probe to each

terminal. With the control at its the tester should

indicate a closed circuit. Turn off the control

then retest; the tester should indicate an open

circuit. To install a new temperature control, pull

the capillary line of the old control out of its

opening. Set the new control to its coldest setting

and carefully thread the capillary line into the

opening without kinking it. Attach the wires to the

terminals, screw the control in place and reattach

the dial.

5. Checking and testing the evaporator motor.

Remove the screws attaching the side to the

evaporator coil housing. Remove the bolts holding

the fan bracket to the coil assembly and Lift the

fan motor a few inches to remove the push on

connectors. Check blade for damage, replace if

necessary. Pull the blade off the motor shaft and

slide on a new blade, taking care not to reverse

the blade. Hold the blade horizontally and spin the

blade to check for binding in the motor. If the

blade does not spin freely, replace the motor. To

test the motor set a multimeter at RX1 and touch a

probe to each motor terminal. The meter should show

resistance. If not, install a new motor, and

reinstall the fan.
