Refrigerator Capacitors

Those normally used on smaller units are of the electrolytic type. They can be considered as being an electrochemical component employed to improve the phase angle relationship between the motor windings when the motor starts and runs.

They may be installed in a series or parallel with the motor windings. If a specific capacitance is not available as a direct replacement, two or more capacitors may be used. The capacitance is stamped on to the casing of a capacitor, and its value is given in microfarads.

A method of selecting and connecting capacitors for making up specific capacitances is given in Figure 40.
