Source1 dt-4jr7540u Dual Run Capacitor 40/7.5 Mfd 370/440V Round

Product Description

The Source1 dt-4jr7540u is a dual run capacitor designed for use in residential and commercial HVAC systems. It carries a capacitance rating of 40 plus 7.5 microfarads and supports both 370 and 440 volts AC, making it compatible with a wide range of equipment. HVAC technicians use dual run capacitors to keep both the compressor and the condenser fan motor running smoothly after startup. A single dual capacitor replaces two separate capacitors, which simplifies the repair and reduces the number of parts needed on a service call. The Source1 dt-4jr7540u features a round form factor, which fits standard capacitor mounting brackets found in most split-system air conditioners and heat pumps. The temperature rating spans from -40 to 70 degrees Celsius, so it holds up in hot attics, rooftop units, and outdoor condensing units exposed to extreme heat cycles. Run capacitors like this one maintain a consistent phase shift in the motor windings. This improves motor efficiency, reduces current draw, and extends the life of the compressor and fan motor. A failed or weak run capacitor is one of the most common causes of an air conditioner that will not start, runs hot, or trips the breaker. Replacing a faulty capacitor with a properly rated unit like the dt-4jr7540u restores normal operation quickly. Source1 parts are manufactured to meet OEM performance standards, making this capacitor a reliable choice for warranty-sensitive repairs and routine maintenance alike. This part is a direct fit for many York, Coleman, and Luxaire systems that specify a 40/7.5 MFD dual run capacitor at 370 or 440 volts.

• Dual run capacitor supports both the compressor and the condenser fan motor in a single unit
• Rated 40 plus 7.5 microfarads at 370/440 volts AC for broad system compatibility
• Round shape fits standard HVAC capacitor mounting brackets and replacement slots

Product Highlights

The Source1 dt-4jr7540u dual run capacitor delivers reliable motor support across a wide voltage range and temperature span, making it a practical replacement choice for HVAC service technicians working on residential and light commercial equipment.
