WOMEN...YOU CAN DO THIS! My A/C went out and my husband is in the hospital so I had to fix this or at least diagnose what the problem was so I don't get ripped off. So the first thing (and easiest) I checked was the thermostat...worked fine. Next, was the Circuit Board in the Heating System...there were no obvious 'burn-outs' or problems. The 3rd, was the CAPACITATOR. I have a Goodman, as you do, so the Capacitor is in the wiring compartment of the actual Air Conditioner, just as the video shows. From another video, I learned that the Capacitator is the #1 culprit (21% of Service calls) of a non-working A/C unit. The actual fan on the A/C worked fine and I noted many A/C's just hum giving you the tell-tale sign it's the Capacitor. But because the A/C was installed in 2004, (15 years ago),and the Capacitor had never been changed out, I figured I'd spend $26 for 2 on Amazon (with 1 as a back-up). The actual fix was less than $14 and 30 minutes of my time. I want to mention how IMPORTANT it is to shut down ALL POWER going into this A/C and discharging (shorting out) the capacitator. The BRIGHT RED WIRE is the culprit. As I was just moving the wires aside, I accidentally touched that red wire and received an immediate and scary shock that I will never forget. SHUT OFF YOUR POWER before you even open the panel and discharge that capacitator...it's real! Anyway, got it done and saved about $400 for a service call, their time and the excess they would charge for a Capacitator. THANK YOU for your video :-)
Thanks for the video. I’m an electrician and just had to replace mine. I also work in the HVAC industry. Everything looks good. Only one suggestion. I’m not sure that the voltage rating is for the minimum voltage as you state. Realize that you are showing a residential condenser and typical utility voltage at most residence in the US is 240 VAC. In this case it would be the max voltage. You are correct to replace at the rated voltage. In commercial applications the voltage can be 208, 240, 277, or 480 Volts. So that 440 may be the rated voltage by which the capacitor works not to exceed.
Thanks for the video. Very well done. All the best to you.
My goodness sir you could be one heck of a proffessor, clearly explained, just what I needed.
Fan didn't want to run, and house was getting hot. I changed out my A/C capacitor a couple of weeks ago. Got it for $22 at the local hardware store (big box hardware stores didn't carry them). Worked like a charm. Thanks for the helpful vid!
Adam is very thorough in his video and truly highlights all the dangers you should first be safe with as well as the details you need to know about testing and replacing a capacitor if it is determined to be bad. By the way, I do electrical work; do listen to Adam about the dangers and turn off the breaker at the main load center panel as well as the disconnect fuses removal after you shut the power to the disconnect. Thank you
While shorting the terminals is always a good idea when handling any capacitor, it should be remembered that capacitors store a charge only when charged with direct current (DC) . Capacitors used in alternating current (AC) circuits do not retain a charge due to the constantly changing polarity of AC. You are not likely to be shocked by the run capacitor from an AC motor. But your advice is sound; better to err on the side of safety. Good video.
Thank you for your stressing safety. So many people breeze through that topic, or casually mention it.I'm going to repeat a story I posted on another site.
I took my grandson to a trade school open house, and as we walked out of an electrician display of graduates, there was a separate display of one particular individual. I asked what was the reason for his distinction. We were told that on the second week of his first job he had electrocuted himself by not following one of the basic rules that were taught at the school. 23 years old.
You never know who might be reached by your emphasis on safety. What is routine mundane practice for you, could reach the right ears and save a life just by emphasizing that important area of professionalism.
Thanks for the video! Was very useful in seeing exactly how to replace my A/C Capacitor. Big time life saver!
very helpful for the one that 's not electrician on DIY hobby,thank you very much.
Best video for DYS I have yet seen .
Thank you !
This is the best video I have seen so far on information.
Thank you so much Adam. I would give you an Oscar bro for that excellent explanation. Great video
Best instructions I've seen to date .. thank you for making this video 👍
Something also to keep in mind here is that capacitors are as dangerous as the 240 VAC coming into the unit. Do not touch the terminals unless you know the capacitor has been discharged completely. It may be defective or degraded but it may still have a high voltage charge on it that will make a bad day for some. These capacitors are high voltage batteries essentially.. I had not watched till the end where you show the discharge... This should be up front with the warning on 240V... Good video...
you are so right. Thanks for the comment!
Yes, I got shocked by one before and it was not pleasant. Safety first.
I didn't listen and have one on hand, mine failed the first run of the season today, ordered two on Amazon just in case. Didn't feel like running outside to get the spec off the cap at night, they don't make it real easy to look it up online either. Even the Lennox PDF on my model only says C12. Repairclinic had it listed as a 35+5 440. My model is the Lennox 10ACC-030-230-03 in case anyone runs into the same issue.

Just to add my "you-can't-be-too-careful" suggestion.... I always discharge when taking a new one out the box. Someone could have returned it, and it COULD (although highly unlikely) have a charge.
Mine went out but no visual signs. The fan wasnt working so I just replaced it now it works. I checked it and the fan side is bad. Thanks for the video!
Nice video I needed a refresher course I don't normally work on AC units but mines down so I needed your help , Thanks !
Perfect video
Thank you very much sir
From Sudan
Thanks Adam! I watched a few videos and this one helped me to get back to where I needed to be in A/C repair. The average cost in the usa is about 175 to 250 for an A/C call where it results in capacitor replacement. One of the things that set this video apart was that there is a 2nd way and actual capacitor testing meter to test the capacitor with which NONE of the other videos I saw said anything about at all???? One of the things I did in error was I checked the capacitor with the fuse pulled (as it should be) however with the wires still connected. With the wires still connected even though I diffused the capacitor it showed a surge on the ohm meter. So I falsely thought it was okay because I could not visually detect any real serious bubleage (is that a word?) on the ends. Okay so because of your video that said even if you do not need another capacitor GET A SPARE! Thats what I did... Okay so I went to Am..zon and got new ordered and decided that I was still going to replace the capacitor BECAUSE OF WHAT YOU SAID... test with both meters. Because I did not have the 2nd meter I decided upon this replacement just in case. Upon removing the capacitor I decided that I would retest again. Low and behold my ohm meter showed one side okay and the other side No surge spike. Somehow by not having the wiring removed it falsed on me earlier. Then because of what we learned I set the cap down on the table and it wobbled lightly like a weeble... So, new cap ordered as you recommended and I feel like a million bucks with as much as $250 saved on an HVAC call. Thanks a billion for your very thorough video. It is what is good about TH-cam and the internet. Hope that helps someone else in my review of your review. Peace.
Thank you, sir. You are great, clear, and professional
Very impressive... Your explanation of every detail is super good! Thanks!
Great video, appreciate your knowledge. I replace my condenser fan, capacitor, and control switch on my Goodman. Turning on unit the inside blower fan started to make noise like it was either loose or motor was going out. Did not find it loose. So ordered a new blower motor. Installed it. Not an ac tech I turned of the disconnect on the box outside. After turning it on and starting the AC. The new motor sounds like the old motor. Turned off disconnect and power to furnace. Tightened down motor frames etc (sounded loose old and new motors). Turned on 220 panel inside forgot about the disconnect outside. But turning on the motor from thermostat. The blower motor came on and had no sound like it should. No cool air out vent. I remembered the disconnect panel outside. Once it was on the new blower motor went back to being noisy. What do you think would make the old and new motors to be making the same noise?
Most complete explaination I have found and understand thank you
Great clear instruction on how to read the capacitor thanks man!
Hey that is the best video on youtube explaining capacitors! Well done!
Can you make one more video in details for contactors, how they work, how to wire them ant etc.
Thanks one more time
Yes that would be very helpful !
There are (3) terminals on a capacitor. The old capacitor will likely be too rusted over to see which is labled which, but take a picture before you remove anything so you can see where the wires go, taking note where the label is may help too. One of the terminals has 4 prongs sticking up, one has 3 prongs, and one has a single prong. Pay close attention to where each wire is as you remove it, and as you remove one wire, put it on the new capacitor, and keep doing this one by one and you shouldn't make any mistakes.
A capacitor is basically a battery that can be charged and discharged literally in the blink of an eye if that is how the circuit is configured. The circuit in the AC unit discharges a capacitor over a second or so (guessing on the time) and gives the fan and compressor that extra 'boost' of power required to get them working, which is why if the capactitor fails the compressor and/or fan will no longer start when power is applied. Unlike a battery though, a capacitor can hold a charge for years, so don't assume a capacitor is discharged just because it isn't plugged in or has been sitting for a while.
One dead giveaway that a capacitor is bad or going bad is the ends will start to expand out as if they are under pressure. Some may start to leak out the dielectric material that is between the two plates that hold the charge. Luckily these capacitors are very quick and easy to swap out.
Not a really technical explaination, but I hope it helped some.
Duct AC main connector sit Nhi hota Kia problem ho skti hy.
I wish I would've watched your video before I called the HVAC guy a few weeks ago. My compressor fan was spinning backwards slowly. Turned out it was the capacitor. The repair guy changed the capacitor and charged the system. Cost me about $340. I believe he charged me about $50 in parts just for the cap. Next time I will do it myself.
Bummer! If your freon was low due to a leak, be sure to find the crack and have the leak repaired or you will have to charge it again in a year or two. That is what one of my neighbors is now dealing with.
I would have charged you 150 -250 for the capacitor. so you actually got a deal.
I replaced my sons AC capacitor last weekend. I also had him clean out the compressor coil which was plugged.
Great video! You refreshed my memory! Thank you!
You do not short across terminals of a capacitors with a screwdriver some capacitors are fused inside and that will make the capacitor unusable. So you need to use your meter to do this set in volts place your leads across the terminals and watch the voltage bleed down to 0 when it is at zero it is safe to handle.
I suppose those small capacitors found in ceiling fans, fridges ect are not fused but those larger ones are. Am I right?
Sorry, this is so late. 370VAC or 440VAC DOES NOT mean that the capacitor will RUN ON 370VAC or 440VAC, but that it is RATED to withstand voltages at those levels. So, what you said about not using a 370VAC-rated capacitor into a compressor that calls for a 440VAC-rated capacitor is true, but the reverse is not.
Thanks Steven!
Thank you very much for the video. Keep teaching.
so glad you made this video. Going to get so much more business from people attaching the wires wrong, or getting the wrong capacitors and damaging the components on the system. not to mention that almost every 440/370 new capacitor is a different size and shape than the OEM one and they will have to make a new mounting bracket for the capacitor. and then theres always the classic touching the low voltage wire on the contactor and destroying fuses and popping breakers and circuit boards. oh what fun it is to go on calls where the homeowner tried to save a buck by learning a skill trade that the people working in that trade have to stay up to date on yearly because of all the changes. I will say this I use youtube as a tool to learn how to do lots of things myself instead of spending more money to make someone else do it. but keep this in mind, your homes HVAC system is the single most expensive piece of equipment in your home. Do you really want to try and save a hundred bucks by risking a potentially very costly piece of equipment? it's up to you. I just hope you watch more youtube videos than this one because this video covered none of the hard parts about changing a capacitor.
could you make a video as to how this capacitor is helping in the running of the AC compressor unit? just came across your channel. awesome ...wish I had found it before
Thank you for great explanation
Great video
I wish you would have shown the bottom of the multimeter. I know the black wire goes in the one marked com. But there are two choices for where to put the red wire.
How come you did not discharge it before you the capacitance test?
Really nice explanation 🙏
The indicated voltage is related to the isolation capacity within the capacitor. 370 Volts means it will withstand 370 V without problems.
Thx- nice, clear and easy to understand!
Great video a lot of information I'm a technician that's been in the field 15 years I've done everything from installing furnaces the diagnosing low pressure chillers and everything in between I was trying to do some research about this Titan pro capacitor my new supplier is using and stumble across your video great work keep it up I'm very happy when I see one of my customers save a few dollars but at the same time there's also certain trade secrets/skills that should always be left to the professionals
I wouldn't be so worried about the voltage as I would the amperage mate!
Wrong.
AWESOME video with some great explanations. I would have preferred the discharge portion be at the beginning, but no big issue.
One question. The replacement capacitor you showed was a 440/370 VAC. You mentioned I t can replace another 370VAC. Am I correct in understanding it can also replace the 440VAC with no problems? The fact that it CAN operate at 370VAC does NOT stop it from working in a 440VAC?
Sorry if that seems a bit redundant, but caps scare the crap out of me...
yes
I am convinced that all these AC guys set out to buy multimeters that look like no other multimeter in existence. How do these devices look nothing like what I see in Home Depot or Harbor Freight???
You’re awesome, soon as I was wondering something you addressed it as if you heard me. You’re also very very well explained. Thanks
Interesting video mate, thanks for sharing
Excellent ...thank you thank you you just saved us $5000
I like the insistence
Yes, 240 power supply is dangerous but not because of the 240 volts. It's the amperage, or current that'll get you. A static spark is thousands of volts and most people can't feel a static spark under a couple thousand volts.
Hello, thank you for your video. if my capacitor is 40/5mf 440V AC., may I use 370/440V AC?
Very good video
Awesome video.Thanks!
at 7:11 Just trying this out: Plus or minus 5% of 60 uF is 3. So, for this capacitor the OK range is 57 uF - 63 uF.
Rocket Rider Correct
Thank you for that sharing sir.
HERM supposedly meant HERMitically Sealed Compressor. I read that somewhere.
I replaced my capacitor and the wires exactly where they were before. The fan is spinning the wrong way. Do I just need to switch the common and the fan wires.
Should a bad capacitor be recycled or thrown in the trash?
I would not recycle. Someone at the recycling facility might get zapped if it's not completely discharged.
Both original and replacement run capacitor are same 12.5 MFD 440/370 VAC but new replaced blower motor has 7.5 MFD listed . Still good ?
Don't you use ohms to test them and if it reads a number then drops to 0 its good?
Great video. Very helpful. Subbed!
Great video
Very helpful . Thanks
Like it
What should be the Minimum distance of Condenser and breaker behind.?????
Nice video. What’s an affordable AC capacitor multimeter you are recommend sir
My capacitor is 50Uf 370U I don't have +x.xx but yet still there is wire going from the capacitor to the fan .
good video, thanks.
Nice video very detailed. Thanks sir
Thank you much. I only have a tester with an ohm 2000 and 200 but do you have to remove all the wires to test?. I tested with wires on and it said 3 for herm and 90 for fan. Does not sound right.
You really should have stated that both the old and the new capacitors HAVE to be discharged before they are handled in the way you are doing in your video.
Show how to discharge
I had one on hand and had to change out to the one but it went out to 6 days later ☹️
Great instruction!
Cheers you just saved me at least $200

video explaining relay circuits?
Could you please tell me what if this capacitor will work for a armstrong concept 1000 model numberscu10g36a-1 serial number1605g06309?"
The capacitor is rusted I can't read the details.
you're awesome man thanks for sharing.
Tanks so much for the video
Thanks. Really Appreciated
Hiya! I just would like to give a huge thumbs up for the great video information you might have right here on this post. I might be coming back to your vid for more soon.
NICE VIDEO, IM GOING TO GET ME 2 CAPS ON HAND,, THANKS
Good work
Do you discharge it while it’s still connected ?
yes
Good my friend thank
Thank you sir 👍🏾🔥🔥🔥
Glad to help! Actually, today was the day my capacitor went out and I used that spare one I keep on hand. My (pregnant) wife is sure happy this 100º day!
@@AdamDIY hahaha lol in Florida today, it was 98° and the capacitor went out, but your video saved me some big bucks in terms of calling a service man to come check it out...
Why is there a shiny spot on the top of the bad capacitor? What does it mean? I have a green dot on mine?!
just had the ac guy replace the capacitor in my ac unit .. he took out a bad 60uf/5uf and replaced with a 80uf/7.5uf ..all is working well.. is it okay to use the higher uf values ??? I am going to order a spare .. which set of numbers should I use ????
glenn bryson thats good to know because ive just purchaced a 5/50uf to replace a 4/50uf hopefully it works
Higher rate capacitors can hold a higher farad but only if they are being fed more power from the source. Should not be a problem but I prefer to replace with equal units unless it's a known issue and replacing with higher uF resolves a known issue
Does your multimeter is has error
great video thank you
Nice sir! I’m changing mines tomorrow. So would it be ok if I just turn off the ac breaker or I have to turn off the breaker by the ac too? Please let me know.
pull the plug either way
mclc432 thank you sir!
Love the video keep it up
Good work✌👍
Very helpful. Thanks!
where do you buy capacitors for motors fans etc?
yes. best video..
If there’s nothing wrong with your A/C can a technician know that it is at 35% if he doesn’t open the air conditioner to look at it?
So I watched this and your old video. My AC is making that buzzing sound. The fan will turn on at random after the AC being off for a few hours but it'll only stay on for an hour.
Took out the capacitor to get a new one and the guy at the store tested the current and said it was okay. So I cleaned my AC unit and put it back in. Had the AC for two hours before the buzzing started again. No clue what to do since the repair guy I called said it was going to be $400 just for him to examine it.
Ugh.
What if not domed but rusted?
thanks that was helpful ;)
Great video. My question is, when so corroded, how do you know which is common or Herm?
helo my dear friend you check multimeter to connect through prope on any two terminal which one difer two terminals high is this compressor .which one is very low this one fan .look like compressor test crs..
Thank fo you infor
How to test a resistor
Adam, was wondering on a dehumidifier if it trips a breaker right after you hit the start button could a bad capacitor cause this. Thanks in advance
Awesome
