Trane CNT9648 Integrated Control Board – Genuine OEM Replacement (Replaces CNT07940)

The Trane CNT09648 is an original equipment manufacturer (OEM) integrated furnace control board designed for various Trane and American Standard furnace models, including the A801X and S8B1 series. This board is the "brain" of your heating system; it manages and controls all operations to ensure it runs efficiently and reliably, from ignition to the blower motor.

Replacing a faulty control board with the CNT9648 (a direct replacement for the discontinued CNT07940) resolves common issues with the furnace’s blower not running, ignition failures, or inconsistent heating operation. It also features built-in diagnostics with an error code display to simplify future troubleshooting.

Key Features & Benefits

Genuine OEM Part: Ensures exact electrical and mechanical specifications, maintaining your furnace’s safety and efficiency ratings.
Integrated Control: Manages all functions: gas valve operation, ignitor control, blower speeds, and safety limit monitoring.
Built-in Diagnostics: Features an error code display via LED light to simplify troubleshooting and quickly identify system faults.
Direct Replacement: A seamless upgrade for the older, discontinued CNT07940 control board.

🛠️ HVAC Depot’s Pro Tip: Take a Picture First!

Control boards are highly sensitive and often misdiagnosed. The most important tip for installation is: Take a clear photo of your old board's wiring before you unplug anything!

This board has many connectors, and one wire in the wrong spot can instantly fry your new component. Always verify power is off, and ensure simpler, cheaper components (like flame sensors or ignitors) are tested first.

Happy Shouts From Our Thrilled Customers

William Bartlett

Cecil really saved me with troubleshooting tips over the phone. Thought I was going to have to replace the blower motor and ended up only needing a motor run capcitor. Thank you and God bless!

Verified Buyer

Riley Connolly

Cecil and Fidel were absolutely amazing and so helpful. We were happy they were open on Sunday, but was impressed with their knowledge and willingness to make sure we had everything we needed. If you need parts or service or install, I would recommend.

Verified Buyer

Cole Meger

Our AC went out during the hottest stretch of summer, and with a one-year-old at home, we were desperate for a quick fix. These guys came through big time — not only did they source the part faster than anyone else in the area, they also walked me through DIY troubleshooting while I waited. Trustworthy, knowledgeable, and run by a solid local family. As someone who owns rental properties nearby, I’ll be sourcing all my HVAC parts from them moving forward. Highly recommend!

Verified Buyer

Carl T. Droste

Had a power outage last night and during the 100 degree heat today noticed that the AC was not blowing any cold air. Pulled the capacitors to have them checked and also took video of the relay making noise even with the breaker was off. The proprietor and her staff were very friendly and helpful. She had the video analyzed and confirmed something was wrong. She checked one of the capacitors was a little low. Capacitor replacement is the biggest ticket item for HVAC repair. It is hundreds of dollars with the a capacitor only about $20.

Verified Buyer

Fuzzy Wuzzy

Cecil and his family have been a life saver. I walked in with very little knowledge on parts let alone how to repair my unit. All I had was my brother in FL who knows more than I do and Cecil at HVAC Depot. With 2 young kids at home I couldn't afford to wait for a HVAC tech. Cecil walked me through what I needed to know, even after hours when the shop closed. I successfully repaired the fan motor and replaced the capacitor. Thank you HVAC team for being totally awesome. Prices were amazing and I'm forever going to support this small family business. You and your family are what Texas is all about!!!

Verified Buyer

Linda Robinson

I called HVAC Depot and was absolutely blown away by the fast, courteous and exceptional service. They were very knowledgeable about explaining what they were doing and what had happened to the ac system. If you ever need a HVAC team they are best and they won’t hesitate by coming out and they won’t leave until you are happy with the service. Thank you so much for your excellent service. Kudos to you Michelle for your amazing customer service.

Paul Hamer

My AC went out in our home on Friday night. I went out and got the capacitor details and took them here first thing Saturday morning. Lady at the counter was friendly and had the capacitor I needed! When I got home, I installed the capacitor and AC is all good!!
