Review: Accurate fit and reliable performance for an older Carrier furnace - This capacitor matched the specifications exactly and worked perfectly as a replacement for our 33-year-old Carrier furnace. Installation was straightforward — the terminals fit tightly, and the size matched the original component, so it mounted easily without modification. The build quality feels solid, with a sturdy aluminum casing and clean, well-fitted connectors. After installation, the furnace fan started running smoothly again, and the capacitor tested precisely on spec with a multimeter. It runs cool and stable even during extended operation. For older HVAC systems, this is an excellent replacement part — dependable, accurate, and well made. It restored full functionality immediately at a very reasonable price.
Review: Pretty good. - Works good and lasts. My AC fan went out and this was the problem. Got me through the summer, time will tell how long it lasts. Overall, not a bad choice for the price.

## Questions & Answers

**Q: What size SSP hard start kit?**
A: Only use a hard start kit if it's old and staring. They come in a range of sizes.

**Q: will this work for replacing 97F9899 Genteq Capacitor?**
A: The capacitor is a 45/5.  The 45 for the hermetic and 5 for the fan.  The voltage should be in range.  The number should be on your old capacitor.  The data I have states that it will work.

**Q: My old capacitor has a 5% tolerance rating. Can I replace it with this one which is rated at 6%?**
A: The tolerance rating is not as important as the voltage rating. Your 220VAC system can be as high as 230VAC. The tolerance is referring to the amount of farads, which will make your motor run faster or slower.

**Q: USA made**
A: No

Works good and lasts. My AC fan went out and this was the problem. Got me through the summer, time will tell how long it lasts. Overall, not a bad choice for the price.

### ⭐⭐⭐⭐⭐ Easy fix that most home owners could do
*by E***E on June 27, 2025*

Watched a YouTube video of the most common Central Air not working fixes. I went out and checked mine as it has not worked a couple of years. Sure enough, the main fan was working, but touching the compressor tube, you could feel it pulling every second or so, but not starting. Removing the old part and measuring it, the fan side was good and the compressor side was bad. Watch some YouTube videos if you dont know how to do that. It's not difficult. Anyways, after kicking myself in the butt for 5 minutes straight, I ordered a replacement here on Amazon. Product arrived fine and appears to be a well built part. Steps to replace it: 1)To start, most units have an outdoor circuit breaker you can pull to de-energize the unit. Pull that and/or flip the switch for the CA unit in your main fuse box. Next, remove the side access port on the outside unit, usually just two screws to get access to where the starter cap and relays are. 2)Checked the old cap to make sure it was de-energized (Very important step!!!). Do not touch those wires if it's still energized! If the unit is truely powered down and you still measure voltage on the old cap, you may need to discharge the old cap. Remember though, there are TWO caps in one and you need to discharge BOTH. If either still has a charge, they could give you a serious bite. Not to scare you away from doing it, you just have to be safe. 3)Marked the color of the wires and where they plugged into on the old cap. Note:Take a couple of pictures of the old cap and what wire goes where on it. This can be good to reference later! 4)Unplugged all the wires from the old cap and loosened the strap holding it in, and removed it. 5)Fit the new cap in under the strap, tighten it down but not so tight that it could dent the new cap, and plugged the wires into the new cap in the same positions as the old cap. Note: In most cases, the compressor will plug into the terminal stamped HERM. The fan goes to Fan if stamped. There are often two wires that were on the same terminal on the old cap, and that is the common. Plug all the wires in and DOUBLE CHECK you did it right. Take a picture of the old one at the start if you're not sure. 6)Put the side access cover back on the unit. 7)Reinstall the circuit breaker. Set the thermostat to turn it on and hopefully you have nice cool air blowing in a few minutes! 8)Especially if this fixes it, a very important step is to order a second cap!!! Then you dont have to wait long if it goes out. These get stressed every time the fan or compressor turns on. They do go bad eventually, so just have a backup ready. You will hopefully get a good 3-5 years out of the cap. In the attached picture, the temp was 78, now 71. Spouse and kids are happy. Therefore. I am happy.
