Genuine OEM Trane SFCAP075440 single run capacitor, rated 7.5 MFD at 440V. This capacitor provides the steady phase shift that keeps a fan or blower motor spinning efficiently — a failed capacitor causes a motor that hums but won't start, overheats, or stops entirely. This factory-matched replacement restores proper torque and reliable motor operation in your Trane unit.

Frequently Asked Questions

Does this Capacitor fit my Trane OEM Trane 7.5 MFD 440V Single Run Capacitor — SFCAP075440?
Yes. This is the factory-specified OEM capacitor for the Trane OEM Trane 7.5 MFD 440V Single Run Capacitor — SFCAP075440. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the capacitor on my Trane OEM Trane 7.5 MFD 440V Single Run Capacitor — SFCAP075440?
Difficulty: Easy (20–30 min)
Step 1: Turn off power at breaker. Step 2: Open condensing unit panel. Step 3: Photograph the old capacitor wiring (Common/Herm/Fan). Step 4: Discharge old capacitor with insulated screwdriver. Step 5: Disconnect and remove old capacitor. Step 6: Mount new capacitor, reconnect wires to matching terminals. Step 7: Close panel, restore power, test. Tools: screwdriver, needle-nose pliers.
My AC hums but won’t start. What part do I need?
An AC that hums but won’t start is the classic symptom of a failed capacitor. The capacitor provides the electrical boost to start the compressor. When it fails, you hear humming but the motor can’t overcome inertia. Other symptoms: fan spinning slowly, AC cycling on/off rapidly, or a visibly swollen capacitor. Fix: replace capacitor ($15–$80 DIY, 30 min).
Is this capacitor compatible with Bryant or Payne too?
Many Trane parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Trane capacitor?
OEM strongly recommended. OEM capacitors have ±6% MFD tolerance vs aftermarket ±10%. The looser tolerance causes motor winding stress, higher temps, and shorter compressor life. Price difference is only $10–$20 — OEM is the clear value choice.
