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.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eDual run capacitor supports both the compressor and the condenser fan motor in a single unit\u003c\/li\u003e\n\u003cli\u003eRated 40 plus 7.5 microfarads at 370\/440 volts AC for broad system compatibility\u003c\/li\u003e\n\u003cli\u003eRound shape fits standard HVAC capacitor mounting brackets and replacement slots\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003ch3\u003eProduct Information\u003c\/h3\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SOURCE1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: dt-4jr7540u\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 370\/440 V AC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapacitance\u003c\/strong\u003e: 40 plus 7.5 uF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRun\/Start\u003c\/strong\u003e: Run\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle\/Dual\u003c\/strong\u003e: Dual\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Rating\u003c\/strong\u003e: -40 to 70 degrees Celsius\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"YORK","offers":[{"title":"Default Title","offer_id":51120797057330,"sku":"DT-4JR7540U","price":39.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/304883358.png?v=1778043225","url":"https:\/\/voomisupply.com\/products\/source1-dt-4jr7540u-dual-run-capacitor-40-7-5-mfd-370-440v-round","provider":"Voomi Supply","version":"1.0","type":"link"}
