With a precise 5 microfarad capacitance and ±5% tolerance, it guarantees efficient motor startup and long-lasting performance. Its robust copper construction and wide operating temperature range (-40℃ to +85℃) ensure reliability in diverse environments. Easy to install with blade connectors and rack mount design, this capacitor meets or exceeds OEM specs, making it the go-to replacement for various HVAC systems. ## Description A capacitor is an electric component that temporarily stores an electrical charge. A "run capacitor" supports electric motors, such as in air conditioner or heat pump units, a fan motor and a compressor motor. The capacitor has two terminals. Capacitors come in a variety of sizes, depending on the capacitance (µF or MFD), such as 40 plus 5 µF, and also the voltage. A 440 volt capacitor can be used in place of a 370 volt, as it is build better, but the 370 can’t be used in place of a 440 volt. It will work for a while and will fail prematurely, as exceeding the capacitor's rated voltage will cause the dielectric to break down and the capacitor to short out. Same as an electric wire- 600V rated wire is better than 300V one .The capacitance(µF or MFD) must be the same or stay within 10%+ or 5%- of its original value . Example: 50 µF cap can be substituted by 47.5 to 55 µF with the same or better voltage ratings capacitor . Round oval-shaped run capacitors are commonly used for air conditioning, to help in the starting of the compressor and the condenser fan motor. Review: Works good so far - Works great. As advertised, direct replacment. Review: Fixed My Furnace! - My gas furnace made a strange sound and wouldn't run. On a lark, I did some Internet searches being careful to describe exactly what was happening. I learned that the sound I described was the blower motor trying to start but was failing because the start capacitor, which provides a short burst of electricity at startup, was burned out. I was nervous but went to the furnace, found the start capacitor and noted its specifications. This part arrived next day via Prime and was easy to install. Wires connect via blade connectors so tools weren't required. My furnace worked! I wouldn't try a repair more difficult than this but am happy to have a $20 furnace repair this time. ## Features - Durable Grade Premium 5 MFD Capacitor for AC Compatible with most Carrier AC Capacitor - Meets or Exceeds OEM Specifications Quality.

And I removed one wire at a time matching each move **Q: My furnace makes a big hum when starting the blower motor. Could the problem be a weak capacitor?** A: Only if it has a weak one. These are normally found at A/C compressors. **Q: Product description says 45+5 mfd, picture shows 50+5 mfd. which is it?** A: 45 **Q: Can i replace my old capacitor wilspec ca370-05v with this. it's 5micron f +-5% ?** A: Yes should work fine ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works good so far *by C***N on August 28, 2026* Works great.
