how to wire honeywell 2 pole contactor sears ac



When it comes to wiring a Honeywell 2 pole contactor for your Sears AC unit, it's essential to ensure that the job is done correctly to maintain the performance and safety of your air conditioning system. The contactor plays a vital role in controlling the flow of electricity to the compressor and other components, allowing your AC unit to function efficiently.

In this comprehensive guide, we will walk you through the step-by-step process of wiring a Honeywell 2 pole contactor for your Sears AC. Whether you are a DIY enthusiast or a professional, this article aims to provide you with valuable insights and instructions to successfully complete the wiring process.

Understanding the Honeywell 2 Pole Contactor

Before diving into the wiring process, it's crucial to understand the basic components and functionality of a Honeywell 2 pole contactor. A contactor is an electrical switch that controls the flow of current in a circuit, and the Honeywell 2 pole contactor is specifically designed for use in air conditioning systems.

The contactor consists of three main parts: a coil, contacts, and a mechanical mechanism. The coil is energized when the thermostat signals the need for cooling. When the coil is energized, it creates a magnetic field that pulls the contacts together, allowing electricity to flow through them. This, in turn, activates the compressor and other components of the AC unit.

Benefits of Wiring a Honeywell 2 Pole Contactor

Wiring a Honeywell 2 pole contactor offers several benefits, including improved energy efficiency, enhanced functionality, and increased reliability of your Sears AC unit. Here are some of the key advantages:

1. Energy Efficiency: The contactor ensures that the compressor and other components only receive power when needed, reducing unnecessary energy consumption. This translates into lower electricity bills and a reduced environmental impact.

2. Enhanced Functionality: By controlling the flow of electricity, the contactor allows for precise and accurate operation of the AC unit, ensuring optimal cooling performance and comfort.

3. Increased Reliability: A properly wired contactor helps prevent electrical issues such as short circuits or voltage fluctuations, protecting your AC unit from potential damage and extending its lifespan.

Now that we have discussed the basics and benefits of a Honeywell 2 pole contactor, let's move on to the step-by-step wiring process.

Identifying the Components

Before starting the wiring process, it's essential to identify the key components involved. Here's a list of the components you will need:

1. Honeywell 2 Pole Contactor: Ensure that you have the correct model and specifications suitable for your Sears AC unit.

2. Screwdriver: A flathead or Phillips screwdriver, depending on the type of screws used to secure the contactor and wires.

3. Wire Strippers: Used to remove the insulation from the wires, creating a clean connection.

4. Electrical Tape: Helps insulate the wire connections and secure them in place.

Now that you have the necessary components, we can begin the wiring process. Follow these steps carefully to ensure a successful installation:

Step 1: Turn off the Power

Before working on any electrical components, it's crucial to ensure your safety by turning off the power supply to the AC unit. Locate the circuit breaker panel and switch off the circuit that supplies power to the AC unit.

Step 2: Remove the Access Panel

Using a screwdriver, remove the access panel to gain access to the existing contactor and wires. Keep the screws in a safe place as you will need them for reassembly.

Step 3: Disconnect the Wires from Existing Contactor

Carefully take note of the existing wiring connections on the contactor. Start by disconnecting the wires from the existing contactor one by one. Take extra caution and label each wire to ensure the correct reconnection later.

Step 4: Remove the Existing Contactor

Once all the wires are disconnected, remove the existing contactor by unscrewing the mounting screws. Set aside the old contactor as it will no longer be used.

Step 5: Install the Honeywell 2 Pole Contactor

Using the mounting screws, secure the new Honeywell 2 pole contactor in place. Ensure it is positioned correctly, aligning it with the existing holes for proper installation.

Step 6: Connect the Wires to the New Contactor

Now, it's time to connect the wires to the new Honeywell 2 pole contactor. Refer to the labels you made earlier for the correct reconnection.

Step 7: Secure the Wire Connections

After connecting all the wires, it's important to secure the wire connections properly. Use wire nuts or electrical tape to insulate the connections and prevent any loose or exposed wires.

Step 8: Replace the Access Panel

Once all the wires are securely connected, reattach the access panel using the screws you saved from earlier. Ensure that the panel is correctly aligned and tightened.

Step 9: Restore Power Supply

Finally, go back to the circuit breaker panel and switch on the circuit that supplies power to the AC unit. This will restore power to the Honeywell 2 pole contactor, allowing it to function effectively.


Wiring a Honeywell 2 pole contactor for your Sears AC unit is an essential task that requires precision and attention to detail. By following the step-by-step instructions outlined in this guide, you can ensure a successful installation and enjoy the benefits of improved energy efficiency, enhanced functionality, and increased reliability.

Remember to always prioritize safety when working with electrical components. If you feel unsure or uncomfortable with any part of the wiring process, it's best to seek professional assistance.

By taking the time to wire your Honeywell 2 pole contactor correctly, you can optimize the performance of your Sears AC unit, keeping your home cool and comfortable during hot summer days.
