Professional Installation Recommended. Review: Match the serial number first - My air conditioner went out last summer and it was due to the old part going out. It didn't cost a lot of money to order this part, and it was exactly what I needed. It fit and since we have put this part on, the air conditioning has been in working order. We compared the new part to the old part and the numbers matched up. Make sure that you check to see if your old part is compatible with the new part before purchasing. Review: Made Heat Pump Much More Efficient, Replaced Old One - Installed as replacement for capacitor in my 3 ton heat pump. Heat pump was not very efficient putting out heat. It would start and run fine but efficiency was poor and not putting out very hot air. Replaced with this capacitor and output of heat pump was much warmer and works so much better. ## Features - Proven EIA-456 compliant 60,000 hour reliability - UL Approved / ROHS Compliant - Patented Pressure Sensitive Interrupter (PSI) for a safe end of life - 45/5 uF Microfarad Rating - 440 VAC Rating ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00EVTIKLC | | Best Sellers Rank | #15,620 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #107 in Industrial Electrical Capacitors | | Brand | Replacement for Goodman | | Brand Name | Replacement for Goodman | | Capacitance | 45 microfarad | | Customer Reviews | 4.7 out of 5 stars 1,830 Reviews | | Item Dimensions W x H | 3"W x 6"H | | Item Shape | Round | | Manufacturer | ZJSSMART | | Material | Polypropylene | | Material Type | Polypropylene | | Maximum Voltage | 440 volts | | Model | Replaces Goodman # CAP050450440RT | | Mounting Type | Snap-In Mount | | Operating Voltage | 440 volts | | Part Number | Replaces Goodman # CAP050450440RT | | Shape | Round | | Upper Temperature Rating | 105 °C | ## Product Details - **Brand:** Replacement for Goodman - **Capacitance:** 45 Microfarad - **Material:** Polypropylene - **Operating Voltage:** 440 Volts - **Shape:** Round ## Images ![CAP050450440RT - 45 + 5 uf MFD 440 Volt VAC - Round Dual Run Capacitor Upgrade - Image 1](https://m.media-amazon.com/images/I/41Awr+ppzJL.jpg) ## Questions & Answers **Q: Will this work to replace a goodman # cap050450440ct? i'm not sure about the difference between the "ct" and "rt".** A: Those are the same parts. They are both round capacitors rated at 45-5uf 440 Volt. Either part will work. **Q: Does this model cover 370 as well as 440?** A: This is a 440V capacitor. If you currently have a 370V, you can go up to 440V with no issues. However, you can not go from a 440V down to a 370V, it will cause a burnout. **Q: can't make out the label entirely... everything looks like a match except i can't confirm the +- spec. my old one here says +-5% what's this one?** A: +-5% is just a variance in tolerance....should not be an issue from one to the other as long as you are matching uF (microfarads) and the VAC Rating....dimensions can differ **Q: Will this fit a model #gsc130361a? serial #060304832??** A: I believe it will. A lot of Goodman A/C's use it as a replacement. If you Google that model number you will see that capacitor replaces the original one. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Match the serial number first *by A***E on July 13, 2026* My air conditioner went out last summer and it was due to the old part going out.
