7.5 Inspection of Capacitor (For Fan Motor and Compressor)
(1) Ohm-meter method
• Set the ohm-meter to the 10M range. Place the
two probes against the two terminals of the
capacitor. At first, the ohm-meter should
indicate small value, then the reading should
gradually increase towards infinity. This
indicates that the capacitor is charging. If the
reading indicates infinity right away (open) or
the ohm-meter fails to move from 0. (shorted),
replace the capacitor.
(2) Capacitance tester method
• Using a capacitance tester and the chart on page 29, test the capacitor for the value indicated.
If the value tested is not within 10 % of indicated capacitance, replace the capacitor.
WARNING
• Properly discharge the capacitor(s) before testing and after testing has been completed.
• Failure to do so could cause damage to test equipment or the unit and/or result in
personal injury (electrical shock) or death.
