My Buying Guides on Lennox Furnace Control Board

When I decided to replace the control board on my Lennox furnace, I quickly realized how important it is to choose the right one. The control board is essentially the brain of your furnace, managing everything from ignition to safety features. Here’s what I learned during my buying journey that might help you too.

Understanding the Role of the Control Board

Before diving into purchases, I made sure I understood what the control board does. It controls the furnace’s operations, including ignition sequences, blower motor speeds, and safety shutoffs. A malfunctioning board can cause your furnace to stop working or behave erratically, so getting a reliable replacement is crucial.

Identify the Exact Model Number

Lennox furnaces have different control boards depending on the model and year. I found my furnace’s model number on the inside panel or the data plate. Using this, I searched specifically for a control board compatible with my model. Buying a generic or wrong model board can lead to installation issues or improper functioning.

OEM vs. Aftermarket Control Boards

I had to choose between Original Equipment Manufacturer (OEM) parts or aftermarket alternatives. I opted for an OEM Lennox control board because it guaranteed compatibility and warranty support. While aftermarket boards can be cheaper, they may not offer the same reliability or support.

Check for Updated Versions

Sometimes, manufacturers release updated control boards that improve performance or fix previous issues. I checked Lennox’s official website and contacted customer support to see if there was a newer version of my board. Using an updated model can enhance furnace efficiency and longevity.

Consider Your Technical Skill Level

Replacing a control board involves working with electrical components and sometimes soldering. Since I’m moderately handy, I felt comfortable doing the replacement myself with proper safety precautions. If you’re not experienced, I recommend hiring a professional to avoid damage or injury.

Review Warranty and Return Policies

I made sure to buy from a seller who offered a warranty and a reasonable return policy. This gave me peace of mind in case the board was defective or incompatible. Always check these policies before making a purchase.

Price and Availability

Price is important, but I learned not to compromise quality for a lower cost. I compared prices from several authorized dealers and online retailers to find the best deal on an OEM Lennox control board. Availability was also key since I needed my furnace back up quickly.

Read Customer Reviews and Forums

Before finalizing my purchase, I read customer reviews and visited HVAC forums. This helped me learn about common issues, installation tips, and trusted sellers. Hearing from others who had the same furnace model was invaluable.

Summary of My Tips

  • Always verify your furnace model number.
  • Choose OEM Lennox control boards for reliability.
  • Look out for updated versions from Lennox.
  • Assess your skill level before attempting DIY installation.
  • Check warranty and return policies carefully.
  • Compare prices but prioritize quality.
