Trane SFCAP30D5440R Dual Run Capacitor 30/5 MFD 440V Round

The SFCAP30D5440R is a precision-engineered Genuine OEM replacement component designed for high-performance Trane and American Standard HVAC systems. Often described as the "heart" of the electrical starting circuit, this dual-run capacitor serves as the critical power reservoir for both the compressor and the condenser fan motor. By providing the necessary phase-shifted electrical current, it ensures that your outdoor unit achieves peak torque during startup and maintains a stable power factor during operation. This specific SFCAP series model is essential for maintaining the efficiency of modern high-efficiency air conditioning and heat pump systems.

Key Features

Genuine OEM Fit: The SFCAP30D5440R is manufactured to original equipment standards, ensuring a perfect physical fit and matched electrical impedance for Trane and American Standard units.
Dual-Function Control: This 30/5 MFD design allows one single component to support both the high-torque requirements of the compressor (30 MFD) and the consistent load of the fan motor (5 MFD).
Noise & Relay Resolution: Engineered to stabilize voltage delivery, this capacitor helps eliminate "humming" noises and prevents premature contact wear on your system's starter relays.
Advanced Safety Monitoring: Features 10,000 AFC (Available Fault Current) protection and is rigorously tested to meet EIA-456 standards for safety and internal pressure relief.
Rugged Construction: Encased in a durable aluminum round-can housing, it is rated for extreme operating temperatures from -40°C to +70°C, resisting vibrations and outdoor environmental stress.

🛠️ HVAC Depot Pro Tip

Take a Picture First: Before disconnecting the old capacitor, take a clear photo of the wiring. Capacitors typically have three terminals labeled "HERM" (Compressor), "FAN" (Fan Motor), and "C" (Common). Using your photo ensures you don't swap these, which could lead to motor failure. Always use a discharge tool or an insulated screwdriver to short the terminals to the casing before handling to avoid electrical shock from stored energy.

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.

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!!
