Replacing a Lennox AC Circuit Board: A Step-by-Step Guide
Replacing a Lennox AC circuit board can be a daunting and potentially dangerous task that is best left to a qualified and certified HVAC professional. That said, some homeowners may choose to replace the circuit board on their own if they are comfortable and confident in their ability to access and handle electric components. If you’re a do-it-yourself type, then you’ll need to know how to properly and safely replace the circuit board in a Lennox air conditioner. This article outlines the essential steps to take when replacing a Lennox AC circuit board.
Step 1: Diagnose the Problem
Before replacing a circuit board, it is important to conduct a thorough process of diagnosis to determine whether or not the circuit board is, in fact, the source of the problem. If there are any other underlying issues with the AC unit, then diagnosing those issues must take precedence over circuit board replacement.
Part of the diagnostic process involves testing the components of the air conditioning system. This can be done by testing the pressure of the refrigerant, measuring the air flow from the system, and checking the voltage and amperage of the unit.
In some cases, a homeowner may be able to diagnose the problem, but should know that this is not an area to skimp on when it comes to hiring a professional for help. Many AC companies will be able to diagnose the problem quickly and accurately, and help you decide whether or not a circuit board replacement is the best solution.
Step 2: Choose an Appropriate Replacement Circuit Board
Once it is determined that the circuit board is the main culprit of the problem, the next step is to select the right replacement circuit board for your particular system. This will require some research, as different models and types of air conditioners require different boards.
The most important thing to remember is to choose a circuit board that is compatible with the Lennox AC unit. This means that the new board must have the same wiring and connectors as the current board. It is also important to make sure that the new board is rated for the amperage and voltage your AC unit uses.
Step 3: Disconnect the Old Board
once an appropriate circuit board is selected and purchased, the next step is to remove the old circuit board from the unit. First, you’ll need to be sure to turn off any power to the unit, including both the AC unit and the circuit breaker.
Then, you’ll need to locate the circuit board, which is typically located near the indoor blower section of the air conditioner. Once found, the old board should be unscrewed from its mount.
Finally, you’ll need to disconnect the wiring from the board and make sure all of the connections are marked to ensure the new board is wired correctly.
Step 4: Install the New Board
Now it’s time to install the new board. Start by following the instructions provided with the product to ensure its proper installation. Be sure to mark and wire each connection according to the instructions.
Once all the connections are made and aligned, you can secure the board to the air conditioner with screws. You’ll then need to turn the power back on to the unit.
Finalizing the Installation
The last part of the circuit board replacement process will involve testing the new board to ensure it is working correctly. Start by setting the thermostat on the highest setting and restarting the AC unit. Keep an eye on it for about an hour to make sure it is cooling properly.
If the AC is running smoothly and efficiently, then congratulations! Your circuit board replacement was a success. However, if the unit is not cooling properly, then you may have to check the connections or rewire the circuit board.
No matter what, it’s better to call a qualified and certified HVAC professional if you experience any problems during or after the installation process of the new circuit board. It helps to make sure that your AC unit is in top condition for the hottest days of summer.
Replacing a circuit board in a Lennox AC unit is a complex process that should only be handled by a trained and certified HVAC professional. If you choose to attempt the replacement yourself, be sure to take the proper safety precautions and make sure the new board is compatible with the unit. While it may be possible to make the repairs yourself, it’s best to save the hassle and leave it to the professionals.

Tips to Avoid Issues with Lennox AC Circuit Board Replacement
Replacing an air conditioning unit’s circuit board can be an expensive, time-consuming process. To help avoid issues, Lennox, a trusted HVAC manufacturer, provides a few preventive action recommendations. By following these guidelines, the likelihood of experiencing costly, frustrating issues can be dramatically reduced.
Manufacturer Recommendations
Lennox urges those performing the service to read all instructions completely to understand the process and to practice caution when working with electrical wiring.

Additionally, the technicians handling the installation should always double-check their connection, ensuring that all components on the installation side are in working order before connecting the line-voltage side.
Local Appliance Company Recommendations
When searching for an appliance company to do the installation, it is important to choose a reliable, certified local contractor. Not only do they typically follow the local state requirements, they also come with experience and are knowledgeable about the current, correct installation procedures and protocols. A qualified technician will be better able to predict, diagnose, and prevent potential issues.
HVAC Technician Recommendations
For more experienced HVAC professionals, they should always use the appropriate tools and materials when handling the job. This means paying close attention to tools and following manufacturer specifications. The technicians should also be sure to wear the necessary protective equipment and proper eyewear.
Lennox AC circuit board installation should also not be attempted without first having the needed safety equipment, such as GFCI outlets, PPE, and circuit breakers. Taking the time to properly inspect the wiring before installation will also help prevent potential issues. Lastly, should the need arise, a technician should always call for additional help to ensure proper ventilation and for additional safety reasons.
Conclusion
Replacing an air conditioning unit’s circuit board can be a complicated process, so following Lennox’s preventive actions can be beneficial in avoiding costly, frustrating issues. Utilizing a reliable, certified local appliance company and qualified technicians can further reduce the likelihood of problems. Additionally, the technicians should always use the appropriate tools and materials with the proper safety equipment and inspection of the wiring before beginning the job. Taking the necessary steps to prepare for and prevent potential issues can save time and money in the long run.
