How to Control YORK AC Without Remote: A Comprehensive Guide

Controlling a YORK air conditioner without a remote can be a daunting task, but with the right knowledge and tools, it’s a manageable process. This comprehensive guide will walk you through various methods to control your YORK AC unit without the need for a remote, providing you with a detailed, technical, and expert-level understanding of each approach.

Locate the Hidden Switch

Some YORK air conditioners come equipped with a hidden switch that allows you to manually turn the unit on or off. This switch is typically located at the back of the unit, near the bottom. To access it, you may need to remove the cover panel.

Identifying the Hidden Switch Location

The hidden switch is usually located on the backside of the YORK AC unit, close to the bottom. It’s important to note that the exact location may vary depending on the model, so it’s crucial to consult your unit’s user manual or contact the manufacturer for specific details.

Removing the Cover Panel

To access the hidden switch, you’ll need to remove the cover panel. This process can vary depending on the model, but generally, you’ll need to unscrew or pry off the panel. Be cautious during this step, as you don’t want to damage any internal components.

Flipping the Switch

Once you’ve located the hidden switch, you can simply flip it to turn the YORK AC unit on or off. Keep in mind that this method only provides basic on/off functionality and doesn’t allow you to adjust settings or modes.

Use an IR Blaster

If your YORK air conditioner has a remote control, you can utilize an IR (Infrared) blaster to control it without the remote. An IR blaster is a device that can transmit infrared signals, mimicking the remote control’s functionality.

Selecting an IR Blaster

When choosing an IR blaster, it’s essential to ensure compatibility with your YORK AC model. Look for a universal IR blaster that can be programmed to work with your specific unit. Some popular options include the Broadlink RM4 Pro, Logitech Harmony, and various smart home devices with IR blasting capabilities.

Configuring the IR Blaster

The process of configuring the IR blaster will depend on the specific device you choose. Generally, you’ll need to follow the manufacturer’s instructions to pair the blaster with your YORK AC unit and program it to recognize the remote control’s commands.

Controlling the YORK AC with the IR Blaster

Once the IR blaster is set up, you can use it to control your YORK AC unit’s functions, such as turning it on/off, adjusting the temperature, and changing modes. The level of control will depend on the capabilities of the IR blaster and the features supported by your YORK AC model.

Use a Wi-Fi Module

Some YORK air conditioners are designed with Wi-Fi connectivity, allowing you to control the unit remotely using a smartphone app or a compatible smart home device.

Checking for Wi-Fi Compatibility

Before proceeding, you’ll need to determine if your YORK AC model supports a Wi-Fi module. Consult the user manual or contact the manufacturer to confirm if this feature is available for your specific unit.

Acquiring and Installing the Wi-Fi Module

If your YORK AC is Wi-Fi-enabled, you’ll need to purchase the compatible Wi-Fi module from the manufacturer or an authorized retailer. Follow the installation instructions provided with the module to properly integrate it with your YORK AC unit.

Connecting the Wi-Fi Module to Your Network

Once the Wi-Fi module is installed, you’ll need to connect it to your home Wi-Fi network. This process may involve downloading a dedicated app, entering network credentials, and pairing the module with your YORK AC unit.

Controlling the YORK AC via Smartphone or Smart Home Device

After the Wi-Fi module is set up, you can use a smartphone app or a compatible smart home device (e.g., Amazon Alexa, Google Home) to control your YORK AC unit remotely. This allows you to adjust settings, change modes, and monitor the unit’s performance from anywhere with an internet connection.

Use a Serial Interface

If your YORK air conditioner has a serial interface, you can utilize a microcontroller like ESPHome to integrate it with your smart home system and gain advanced control over the unit.

Identifying the Serial Interface

Locate the serial interface on your YORK AC unit, which is typically a set of pins or a connector. Consult the user manual or contact the manufacturer to confirm the presence and specifications of the serial interface.

Selecting a Microcontroller

For this method, you’ll need a microcontroller that supports serial communication, such as an ESP8266 or ESP32 board. These boards can be programmed using ESPHome, a popular open-source platform for creating custom firmware.

Connecting the Microcontroller to the Serial Interface

Carefully connect the microcontroller to the serial interface on your YORK AC unit, following the manufacturer’s guidelines and wiring diagrams. This may involve soldering or using specialized connectors.

Configuring ESPHome

Use the ESPHome platform to create a custom firmware that can communicate with your YORK AC unit through the serial interface. This process involves writing configuration files, defining the air conditioner’s capabilities, and integrating the firmware with your smart home system.

Integrating with Smart Home Platforms

Once the ESPHome firmware is set up, you can integrate it with various smart home platforms, such as Home Assistant, allowing you to control your YORK AC unit through voice commands, automation, and advanced scheduling.

Use a Power Monitor Plug

If you want to monitor the power consumption of your YORK air conditioner, you can use a power monitor plug. This device can measure the current and voltage of the AC unit and provide data to your smart home system.

Selecting a Power Monitor Plug

Look for a power monitor plug that is compatible with your YORK AC unit’s power requirements and can integrate with your smart home platform of choice. Popular options include the Sense Home Energy Monitor, Emporia Vue, and various smart plugs with power monitoring capabilities.

Connecting the Power Monitor Plug

Plug the power monitor plug into the wall outlet, and then plug your YORK AC unit into the power monitor plug. Ensure that the plug is properly rated for the power draw of your air conditioner.

Integrating with Smart Home Platforms

Configure the power monitor plug to connect with your smart home platform, such as Home Assistant or Amazon Alexa. This will allow you to monitor the YORK AC unit’s power consumption, determine if it’s on or off, and potentially integrate the data into your home automation routines.


Controlling a YORK air conditioner without a remote can be achieved through various methods, each with its own set of technical requirements and capabilities. By understanding the hidden switch, IR blasters, Wi-Fi modules, serial interfaces, and power monitor plugs, you can take control of your YORK AC unit and integrate it seamlessly into your smart home ecosystem.

Remember to always consult your YORK AC unit’s user manual, manufacturer’s guidelines, and safety precautions when attempting any of these methods. Additionally, some techniques may require a certain level of technical expertise, so be prepared to invest time and effort into the setup process.

With this comprehensive guide, you now have the knowledge and tools to take charge of your YORK air conditioner and enjoy the benefits of enhanced control and monitoring, even without the original remote.
