TESTING

1. Tag and disconnect all wire leads.

2. Use a multimeter set to read HIGH RESISTENCE and place meter leads on terminals of the capacitor.

3. If the capacitor is good, the multimeter needle should move rapidly toward the low-end of the scale, then slowly

return to infinity. If the needle moves to zero and holds steady, the capacitor is internally short circuited. If the

needle does not move, the capacitor has an open circuit. Replace if t he capacitor indicates a short circuit, an open

circuit, or has other damage.

4. See WP 0028 00, Wiring Diagram. Connect all the wire leads and remove tags.

REPLACEMENT

1. Using a screwdriver with an insulated handle, discharge the capacitor.

2. Loosen four screws (1), securing strap (2), holding evaporator run and condenser-run capacitors (C2 and C3) to the

Top Rear Panel. Do not remove the strap.

3. Remove the capacitors by sliding out from under the strap. Retain the insulator pad (4) from between the capacitors.

4. Tag and disconnect all wire leads.

5. Place the capacitors (3) and insulation pad (4) into the strap (2).

6. See WP 0028 00, Wiring Diagram. Connect all wire leads and remove tags.

7. Tighten four screws (1), scouring strap (2), and holding capacitors (3).
