45/5 uf MFD 440

Great product and easy to install. Just ALWAYS ALWAYS ALWAYS pull the breaker on your power supply to your air conditioning unit VERY VERY IMPORTANT, BE SAFE and make SURE breaker is off... then simply take a photo of how the wires are connected to the old capacitor, then replace with this new one, snap the wires in place EXACTLY as hour photo shows, then you’re finished. Easy. This $16 part saved me the $800 service call that I’ve had to spend before. And this capacitor works great!

It was physically smaller than the cap it replaced, but same electrical specs. Works great, and saved a lot of money doing it myself.

This is the 2nd time I have purchased this part. First time was the summer of 2016. Turned the central a/c on and the fan was not spinning. Did some research that said it could be the capacitor so for $18 I figured it couldn’t hurt to order this and hope that was the fix. Sure enough it was! No fast fwd to now summer 2023. Turned on the center a/c for the 1st time of the season. While everything was running including the fan, it just wasn’t dropping the temperature. I figured I’d give this part a try again and just like before, problem solved!! So for $18 bucks and literally less then a minute to install I’d say this is worth having to buy every few years. Last capacitor lasted 7 summers!

Nothing like your air conditioner going out in the middle of the night or on a weekend, and having to pay $200+ for a repairman to come out. These capacitors are usually the culprit when the outdoor unit's compressor or fan won't come on. There are numerous YouTube videos on how to replace these. I keep an extra one in the garage just in case - and had to use it one time at 10:30 at night when I was to leave on a week-long business trip the next morning.Transfer the wires from the bad to the good one at a time -"C" to "C", "HERM" to "HERM", "FAN" to "FAN". Take your time.The new capacitor may not have the same form factor as the old one, but as long as the 45/5 or 45+5 values match, you're good. And it's OK if the rated voltage on the new one is higher than the old one (440VAC vs. 370VAC).A failed capacitor doesn't always show physical signs of failure. Sometimes the top of it (where the terminals are) will look puffed up, and sometimes it will look fine. When the unit stops cooling suddenly, I try replacing the capacitor first thing. For less than $20, it's worth a shot!Just be careful if you decide to replace this part yourself - shut off all power to the A/C unit before opening the cover! That includes turning off your thermostat.The 45uF side of this capacitor supports compressor operation (the HERM terminal); and the 5uF side supports the fan (the FAN terminal). The "C" is the common terminal for both.

Ok, so it gets 4 stars because it came fast (2 days and I ordered it Friday before Memorial Day weekend and it delivered on SUNDAY), it works, and it saved me the ~$350-$400 AC repairman ~this is a nice neighborhood~ rape job pricing. It got minus one for being a very different size than the 45/5 cap in my unit. I made an improvisation in the mount that I'm not 100% happy with, but hopefully will hold up. Knowing it is much smaller than most 10 yr old caps, would it kill them to throw a piece of that cheap pre-punched hole metal strap in there, and a 3/4-1" screw (to provide for some slop in distance between punched holes) that people can use to remount it? Charge an extra $3 for the trouble.

Clearly my A/C's start-run capacitor had expired.So why didn't I have my local HVAC repair man fix my issues? Well I did initially but they want $69.00 to show up, then they want another $300 to remove and replace the part. Are they out of their minds?I maybe old but I'm not stupid ! There is a reason they WILL NOT give you a reasonable quote over the phone.So I ordered 2 replacement capacitors (one as a duplicate), both arrived On Time, matched the OEM Spec replacement, 10 Mins later we have coolness. Yes it only took 10 mins start to finish.So where is the value to have someone do this for me?? This is a major rip-off.I would recommend this part.

Fit perfectly, heat pump fired up normally.

Most likely you are on the right path to save you hundreds dollars if you are looking at the capacitor. Yes, it saved me in the over 110 degree summer day. Just simply swapped this capacitor and my AC back working again.Although too early to tell its longevity, I believe it should last like 5 years. Highly recommended if its spec matches the old one you are replacing.Just a safety tip that always disconnect the power and discharge the old capacitor before touching it!!!
