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.
