What Type of Contactor is Needed for York AC Model H1RA036S06A


When it comes to ensuring the smooth functioning of your York AC system, choosing the right contactor is crucial. The contactor is an essential component that controls the electrical current flow to the compressor and condenser fan motor. If your York AC model H1RA036S06A requires a new contactor, it is important to understand the specific type of contactor needed to maintain optimal performance. In this article, we will explore the different factors to consider and provide guidance on selecting the appropriate contactor for your York AC model H1RA036S06A.

Understanding Contactors:

Contactors are electromechanical devices responsible for switching heavy electrical loads on and off. They control the power supply to motors, compressors, and other high-current electrical components within an AC system. In the case of York AC model H1RA036S06A, the contactor acts as a bridge between the thermostat and the compressor/condenser fan motor.

Types of Contactors:

There are several types of contactors available in the market, each designed for specific applications. When selecting a contactor for your York AC model H1RA036S06A, it is crucial to consider the following factors:

1. Rating and Compatibility: Contactors come with different voltage and current ratings. To ensure compatibility, it is necessary to choose a contactor with ratings that match the specifications of your York AC model H1RA036S06A. This information can be found in the user manual or by consulting a professional HVAC technician.

2. Single Pole vs. Double Pole: Contactors can be single pole or double pole. A single-pole contactor controls only a single electrical phase, while a double-pole contactor handles two electrical phases. For most AC systems, a double-pole contactor is preferred as it offers increased safety and reliability.

3. Coil Voltage: The coil voltage of the contactor determines its compatibility with the control circuit. It is crucial to ensure that the coil voltage matches the voltage supplied by the thermostat in your York AC model H1RA036S06A.

4. Enclosure Type: Contactors are available in different enclosure types, including open frame, dustproof, and watertight. The type of enclosure required depends on the installation environment of your AC system. If your York AC model H1RA036S06A is installed in an area prone to dust or moisture, it is recommended to opt for a contactor with appropriate enclosure protection.

5. Brand and Quality: Choosing a reputable brand and high-quality contactor ensures durability and long-term performance. Preferably, select a contactor from the same manufacturer as your York AC model H1RA036S06A to ensure compatibility and reliable operation.

Replacing the Contactor:

Now that we have a better understanding of the factors to consider when choosing a contactor for your York AC model H1RA036S06A, let's discuss the steps involved in replacing the contactor:

1. Turn Off Power: Before performing any maintenance or repair work, ensure the power supply to your AC system is turned off. This can be done by switching off the circuit breaker dedicated to your AC unit.

2. Locate the Contactor: The contactor is usually located in the outdoor unit of your AC system, near the compressor and condenser fan motor. It is a square-shaped device with several electrical connectors.

3. Identify the Wiring: Take note of the wiring connections before removing the old contactor. You may want to take pictures or label the wires to ensure proper reconnection later.

4. Remove the Old Contactor: Carefully disconnect the electrical wires from the contactor. Depending on the model, it might have screws, bolts, or push-in connectors. Be mindful of the orientation of the contactor to install the new one correctly.

5. Install the New Contactor: Place the new contactor in the same position as the old one, aligning it properly with the electrical connectors and mounting holes. Ensure the electrical connections are secure and tight.

6. Reconnect Wiring: Refer to the labels or pictures taken earlier and reconnect the electrical wires to the corresponding terminals on the new contactor. Double-check the connections to avoid any loose wiring.

7. Turn On Power: Once the new contactor is securely installed and the wiring connections are made, you can turn the power back on by switching on the circuit breaker. Verify that the contactor engages when the thermostat calls for cooling.

Maintaining Your York AC System:

To keep your York AC model H1RA036S06A in optimal condition, regular maintenance is necessary. Here are some tips to help maintain your AC system:

1. Clean the Outdoor Unit: Regularly remove any debris, leaves, or dirt that may accumulate around the outdoor unit. This ensures proper airflow and prevents the contactor and other components from getting clogged.

2. Replace Air Filters: Clean or replace the air filters as recommended by the manufacturer. Clogged filters can restrict airflow, reduce efficiency, and strain the contactor.

3. Schedule Professional Maintenance: It is advisable to have a professional HVAC technician inspect and service your AC system annually. They can identify and address any potential issues, including contactor wear or damage.

4. Monitor Performance: Keep an eye on the performance of your AC system. Unusual sounds, irregular cooling, or increased energy consumption could indicate a faulty contactor. If you notice any issues, contact a professional technician for assistance.


Choosing the right contactor for your York AC model H1RA036S06A is essential for proper functioning and optimal performance. Factors such as rating and compatibility, pole configuration, coil voltage, enclosure type, and brand quality should be considered when selecting a contactor. Replacing the contactor requires proper precautionary measures, including turning off the power, identifying wiring connections, removing the old contactor, installing the new one, and reconnecting the wiring. Regular maintenance and professional inspection help to keep your AC system in peak condition. By following these guidelines, you can ensure the longevity and efficiency of your York AC model H1RA036S06A.
