sheet metal screws that hold the top cover
to the control box. Remove the top cover.
3. With the 5/16” nut driver and 5/16” wrench,
remove the 6 screws that hold the control

as the leads will allow.
4. Discharge the field capacitor by connecting
the jumper wire clips on the black and the

to their respective terminals [202 and 202B
Red to positive (+); 201C, 201B and 201A

screws securely. Snap the capacitor back
into the molded plastic holder and slide the
holder back into position in the panel.
Replace the tie wrap.
