CONTACTORS

Contactors are simply an electromagnetic switch that let
the main power in to the air conditioning unit. They are
controlled by an electromagnetic coil that engages the
contacts.

When replacing a contactor you should look for the
following things:

Determine how many spring-loaded contacts it has (most
units have 1 or 2).

Find the coil voltage. (Most AC contactors run on a 24 volt
coil, but there are some that run on 120 or 240 volts.)

Find the Full Load Amps (FLA). This is the amperage rating
that the contactor can handle. This is usually located in a
chart on the contactor itself.

Below are some contactors we carry in our
online store.
