Method and system for controlling a compressor

A method for controlling the motor of a compressor with a system, wherein said system performs the method comprising the steps of:

• switching at least one contactor connected to a source of line power to remove the source of line power to a set of relays and to a compressor motor containing a run winding, a start winding, and a common lead;
• controlling the set of relays by switching the set of relays to provide the source of line power to permit switching the source of line power to either the run winding or the start winding, wherein prior to said controlling, the at least one contactor removes the source of line power from the set of relays;
• and
• waiting a predetermined period of time before performing said controlling.

A computer readable medium containing computer software, which, when run on a computer causes the computer to provide apparatus for controlling the motor of a compressor, the apparatus comprising:

• means for switching at least one contactor connected to a source of line power to remove the source of line power to a set of relays and to a compressor motor containing a run winding, a start winding, and a common lead;
• means for controlling the set of relays by switching the set of relays to provide the source of line power to permit switching the source of line power to either the run winding or the start winding, wherein prior to switching by said means for controlling, the at least one contactor removes the source of line power from the set of relays;
• and
• means for waiting a predetermined period of time before the means for controlling switches the set of relays.
