CAPACITOR - TEST
1. Remove capacitor from unit.
2. Check for visual damage such as bulges, cracks, or leaks.
3. For dual rated, apply an ohmmeter lead to common (C) terminal and the other probe to the compressor
(HERM) terminal. A satisfactory capacitor will cause a deflection on the pointer, then gradually move back to
infinity.
4. Reverse the leads of the probe and momentarily touch the capacitor terminals. The deflection of the pointer
should be two times that of the first check if the capacitor is good.
5. Repeat steps 3 and 4 to check fan motor capacitor.
NOTE: A shorted capacitor will indicate a low resistance and the pointer will move to the "0" end of the scale and
remain there as long as the probes are connected.
An open capacitor will show no movement of the pointer when placed across the terminals of the capacitor.
