The best way to discharge a capacitor is to set your multimeter to Volts. Go across each terminal and read your meter and you will see it go to 0 Volts. I was taught this way, safest and professional way. Good vid!

I did research and found the likely culprit was the capacitor, but I felt a little uneasy messing with it. After watching your video my confidence was boosted. I ordered a replacement capacitor, followed your steps, and I am very happy to say I have A/C again!

I love the “How do I know this? Because I tried it” bits 😂 Thanks for adding some comedy to this very helpful instruction video. &Thank you for making this video in the first place! My grandma’s A/C went out (mid summer in the valley - worst timing EVER) and the repairman quoted nearly $500 for the repair. He said the capacitor needed to be replaced(2nd time for this system) & told my grandma it was possible to replace it without hiring a professional. I’ve worked on cars in the past and am pretty good with repairs, so I’m going to save her about $400 by doing the job myself. The only bit I was worried about was discharging the capacitor, which led me to this suuuper helpful video! :) My grandma and I both really appreciate it!

One of the first things I was taught in HVACr school is that "there is always more than one name for something and there is often more than one way of doing something, just get used to it." So I embrace the idea of different techs doing it differently, that makes it more interesting! But your way really is the more technically correct way 😇

I can't thank you enough for posting these vids. My old capacitor was a 70+10 +/-6%. The new one I installed (thanks to you) is a 70+10 +/-5%. Does this 1% difference matter? Again, TY for being so thorough and speaking for the true beginner, and never assuming that we "must already know" certain details that others leave out, that could kill us if we don't.
@IanCazabat

Nope, the +/- is the tolerance of the measurement. So, 70+10 +/-5% = means the herm should be between 66.5-73.5 (which is +/- 3.5 or 5% of 70), and the fan should be between 9.5-10.5 (which is +/- .5 or 5% of 10).

Hey Jeremy! What TK said might just be what it is. (thanks TKGotWings_!) Another thing you can look for is an air cycler control (I don't remember the specific name for it), typically located somewhere on the side of a duct, by the furnace/air handler. Some houses will have that thing installed and it basically does the same thing as that circulate option on the thermostat.

True, the method you use is the fastest way to discharge a capacitor, but can also damage the capacitor. Using a resistor for discharging may take a couple minutes longer, but is less likely to do any damage and is a little safer, because in discharges gradually instead of a sudden jolt.

Maybe if the capacitor is dead there wouldn’t be a spark (even slight). I just swapped out a cap here at home (first time doing it…pretty easy for sure). I shifted the wires from the old to new leaving the old still mounted in the cabinet. Then removed the metal strap from the old and finally affixed the new. The new one has a smaller diameter so fortunately, the metal strap has several holes. Lastly, I discharged the old cap. No fireworks 😢 Kick on the A/C and back in business. Just for reference, the original cap was in operation for six years. Location is Indianapolis so the A/C gets used a bit throughout the summer. Lastly, suggest to buy American made caps from AmRad.

Glad you liked the story! Yes, any regular screw driver or even a pair of pliers is all that is needed to discharge it. Sorry to hear about the AC problems, I've lived in toasty environments like that before so I know what it's like. Likely this has nothing to with spraying the unit down, from what you described it does sound like a bad capacitor. If you want to clean the outside coil, you could try brushing it and vacuuming it. It's not going to do as good of a job but if there is a bunch of stuff on that coil, you will still lessen the air restriction.

Follow this method, you'll be buying your customers a brand new capacitor. Using a screwdriver across the terminals can cause interruptions in the cap. Even if it is not seen immediately, it will over time become unable to maintain a charge. That will lead to failed motor starts, or drag on the motor which will cause damage to the motor.

You can shorten the lifetime of electrolytic capacitors by shorting them. Internal hot-spots may develop and cause some of the electrolyte to vaporize, and potentially damage the thin aluminum-oxide dielectric, leading to increased leakage currents and more internal heat generation (and shorter life). Just because a component didn't immediately die, doesn't mean you didn't damage it.

Exactly "Darren Holdstock Joined Feb 10, 2009 262 Jan 13, 2010 #4 Yes, discharge with a resistor or the cap may be damaged by the current surge (some types of cap are more easily damaged than others). If you dead-short it then almost all the energy stored in the cap will be suddenly dumped in the equivalent series resistance (ESR), which can cause localised burnouts and fractures. That energy, in joules, is (CV^2)/2." That said, the amount of charge in most capacitors is miniscule, about like touching a doorknob after walking across a carpet. When I was in Marine Corps Avionics, a favorite prank would be to charge a cap to 450 VDC and toss it to an unsuspecting friend (A 45 mF cap at 450V holds 4.556 Joules. A cardiac defibrillator discharges 200-400 Joules which it stores in capacitors). Unpleasant? Yes. Injurious? No. But how many HVAC caps have failed prematurely due to having their terminals shorted without a resistor to control the current. And unless the motor windings are open or the thermal cutoff has tripped and not reset yet, there is unlikely to be any charge present as it will discharge through the motors windings which are fairly low ohms. But you can easily use a voltmeter to check to see if it's charged. Just use a resistor if you discharge it.

What HVAC manufacture would you recommend? I currently have an American Standard. It’s 27yrs old and been a great system. Wondering if American Standard/Trane is still the system to beat. Carrier? Bosch? Thanks for any advice.

Could you make a video on unhooking a 250v ceiling fan capacitor and discharging it?

Great video, your videos are so informative and easy to understand 🙌🏻👍🏻 Do you need to discharge the capacitor before disconnecting it from the unit to replace with a new one ? Thank you 🙏

Thank you, I'm glad to hear that the video are easy to understand. Preferably yes, discharge the capacitor every time before disconnecting any wires (power is off of course)

Hello we have a gsx14 and it will trip the breaker after running for a good while. I've watched all your hvac videos and thanks so much for all the info you share with us. I've check all the components no shorts capacitor is within range and the inrush amps are good. Any suggestions would be greatly appreciated. Thanks again for sharing your knowledge with us.

I'm amused by the discharging guys, any run cap is connected both ends to the motor and self discharges. A start cap usually has bleed resistor. Beyond that used me volt tester to bleed off. The only caps worth worrying about the DC electrolyic found on inverter boards that really pack a punch and don't short them!

Lol thanks for clarifying Nathan! In most cases that is true but there are many different units out there and some of them actually do bite. 😄 My idea is to be on the safe side and take the few extra seconds to discharge it. Thank you for the heads up about the inverter boards too!

Ty for making the video. If you knew why a capacitor would not work the same in a DC circuit you would not have this many misunderstandings about a standard capacitor. If what you're saying is true, how could anyone work on a mini split with super caps? 100% though for safety I run my strippers over any cap I'm about to service.

How long to capacitors hold a charge? Minutes, hours, days? Can you leave something off/unpowered for some period of time and they’ll discharge?

I bought an insulated screwdriver with orange insulation to the bit to complete this but now I’m worried that in needs to be direct metal? So just a regular screwdriver with a insulated handle?

Question, if just changing the fan blade, maybe it's bent or cracked etc...motor is fine...after pulling out the fuse on the outside wall, do you have to shortout the capacitor, does that capacitor have enough juice in it to make that fan blade spin while taking it off the motor....

If your screwdriver accidentally touches the body of capacitor will it ruin the capacitor or make it weak ?

When shouldn't one use the screwdriver method? Are there capacitors powerful enough for this not to be safe?
@k9cj5

Thank you for this. I was wondering, can you discharge the capacitor by unplugging the HVAC unit, hooking the motor directly to the kill switch and pressing the kill switch to complete the circuit? (similar to testing the motor without the power being plugged in?) I do this all the time with electronics before I open them up and mess with them. Curious if this method would work with AC power as it does with DC. Thank you for your time
