OVERLOAD CHECK

COMPRESSOR CHECK

CAPACITOR CHECK

Using a volt–ohmmeter check the continuity

across the overload, contact #1 and #3. If none,

wait for unit to cool down and try again. If still no

continuity, the overload protector is defective

and should be replaced.

FIGURE 18. OVERLOAD CHECK

The resistance readings on the windings will be

between 0.25 to 10.00 ohms, a meter capable of

these low readings must be used.

1. Check between “C” and “R.” Replace the

compressor if there is no continuity as the

run windings are open.

2. Check between “C” and “S.” Replace the

compressor if there is no continuity as the

start windings are open.

FIGURE 19. COMPRESSOR CHECK

3. Check between “C” and “R” or “S” and the shell of the compressor. If there is continuity, replace the

compressor as the motor is grounded.

4. Check between screw terminal on the overload and “C” on the compressor. Check and repair the

lead or connections if there is no continuity.

1. Check or replace start capacitor,

disconnect bleed resistor before checking

for shorted capacitor.

2. Check or replace run capacitor (if

supplied) check for shorted capacitor or

either terminal grounded to case.
