  • The use of compressor start devices results from a need to ensure that a compressor usually air conditioning will start under voltage conditions that are less than ideal.
  • Upload your photos or documents here!
  • The wiring for the air conditioner condenser fan motor will likely have the black wire noted in the wiring diagram go directly to the compressor contactor.
  • It is important to make a proper connection from the wire to the connector and a tight connection from the connector to the capacitor.

Voltage sensing technology that monitors for motor start current sensing devices require internal fuse protection. Energy Efficiency for Your Home. Blower fan motors and other fan motors may have what look like extra wires, not all of which may be in use, depending on the fan speeds required. Anything you would like to say about these photos? We cover those factors in the linked to articles.

Start devices exist in many forms for specific applications. Here we will illustrate the proper wiring for a motor to a run capacitor. Author and others have been zapped!

Turn power off and discharge any capacitors before touching anything. Search the InspectApedia website. There are important reasons for this that can affect the comfort produced by the appliance. The air conditioner condenser will usually only run in the summer.

When a heat pump goes into the defrost cycle the condenser fan motor for the heat pump will shut down. It'll otherwise have enough power stored on it to be at least very painful. Get as much information as possible especially if you have never done it before.

Condenser fan motors and Capacitor wiring

  1. The wiring for the heat pump condenser fan motor will be slightly different.
  2. Failure to make a good connection can result in a failed connection and that could cause the motor to burn up.
  3. You should see a wiring diagram glued to the inside of the air handler cabinet or to the inside of the blower compartment door.
  4. Never work on live electrical equipment.
  5. It also controls the condenser fan motor in a heat pump.
Types of Motors

The heat pump condenser fan motor will not. When testing a compressor, one must discharge the capacitor first! This enhances and quickens the defrost cycle. Name Enter your name so we can credit you. Usually connects to C or Common terminal on the Capacitor.

To do this you need the proper tools, wire, and wiring accessories. Usually connects to R or Run terminal on the Capacitor. The black wire noted in the wiring diagram will likely be terminated on a control board. Bracciano, Goodheart-Willcox Co.
