Thank you very much. I knew this was possible but wasn't sure about the connections and polarity on the single split capacitor. I later realized polarity doesn't matter on these single ones so hooked it up and it works. Thanks again
Thanks, man! This happened to my 2000 ac unit. The compressor works but the fan wont start on it's own, without a push. At some time in the past, someone added a small 5 run capacitor to the origination duel 35/5...but they didn't use jumpers. It' wired weird with brown fan wires going over thee top on the unit to the fan. The original dual cap has TWO yellow, wires on one terminal and TWO hots to one terminal. I'm just going to leave all that as is, and replace the little 5 capacitor.
I wish my A/C unit had the wiring diagram on the access panel. My A/C unit is 22 years old & I've had to replace the capacitor twice. I now keep an extra on hand. Last week I replaced the capacitor on my sister's dinosaur A/C system. I think that unit was older than me. FYI, a good HVAC channel that has a lot of great info is "Word of Advice TV".
If you get the Make/Model off of it and call the manufacturer they will send you a diagram. They have to make them available by law. I ordered a 2 pack of dual caps myself. That way I will have one on hand as well. Home Depot used to stock them, but they are special order now.
Hi, that's a dual run capacitor. But, how does the compressor and condenser fan motor work without a START CAPACITOR? I've always thought that a start capacitor was needed to start the compressor and condenser fan motor. And then the run capacitor takes over. Thanks
The capacitor for the fan motor is to adjust the phase of the motor slightly so I will start and run in the right direction. The compressor is a start capacitor.
I’m not a tech but why change a single dual capacitor into two capacitors when the manufacturer put in a dual capacitor? Saying this because that’s what a tech did to my AC unit. Then I got billed for replacing two capacitors.
@@frugalprepper but the fan when in the beginning works perfectly. But after a minutes turn of. I understand that the capacitor it is to turn on the fan. But which capacitor or part keep the fan on?
Well you have a 2 pole cap that runs on the Compressor and a 2 pole cap for the fan. The Dual cap has one terminal in common and the other are compressor and fan. There are also tough starting caps and relays on some units.
Is there any reason you couldn't permanently leave it like this? I have a Carrier RV a/c that works fine, except they don't make parts for it anymore. It originally had a 45/12UF but nobody makes that anymore. A friend told me to just use a 45/10, but after doing that, the fan sometimes doesn't fully kick on. Then another friend who is an A/c guy told me it has to be in specs. So the only solution is to wire up a 12 by itself and do what you did here. Just wasn't sure if it would hurt anything to leave it long-term like this.
I have a question. My unit has 5 wires, 3 for C, 1 for H and 1 for F. So, i bought 2 capacitors of 25f and 6f for the unit. Should i connect the herm wire to the bigger capacitor or the smaller one?
The compressor (H) will be the larger capacitor. The fan (F) will be the smaller capacitor. The commons (C) will go to the other sides of those capacitors bridged together.
You should do research on how capacitors work, what “common” is, and read the wiring diagrams, getting an all round understanding of the electric is the only foolproof way to know what your doing is correct for your unit
Common will always connect the two capacitors together, or you can run common from them both directly to the contactor, there’s different ways of doing things so the best way is to have an all round understanding of how they work and why
If your fan has two brown wires (solid brown and brown/white) do you just attach both browns to the 5 MFD Run Capacitor? I'm in a similar situation but my universal fan replacement motor has 4 wires total (2 being browns)
If you are just putting in a extra cap like a 145 to 175, you can just put it in bewee the hot and the herm connection. If you are putting one in with relay, you would have to follow the directions that come with the kit.
Thank you very much. I knew this was possible but wasn't sure about the connections and polarity on the single split capacitor. I later realized polarity doesn't matter on these single ones so hooked it up and it works. Thanks again
Glad it helped
Great job explaining where the wires go and why!
107F out 88F in house now. I did get the compressor fan working again. Sadly the compressor side was bad as well. Now I cook waiting for part.
Thank you for your video. It got my a/c up and running in a heat wave. Thanks again!
Fantastic! Glad it Helped!
I just had to do this. Definitely works in a pinch. Good video.
Glad it helped

Good video! Very clear and precise. You are a natural teacher.
Wow, thank you!
Dude thank you just fixed a trance because of you
Thank you for refreshing my memory 👍🏼👍🏼
Any time!
👍 almost set up like a soft start for an RV. Thanks for the video Tom.
This vid saved me I work on pool heat pums so I had fan caps.... fix moms ac on a hot Florida night
Thanks, I am in Ohio, but Heading down to Florida day after Christmas to enjoy some nice weather and ride coasters at Bush Gardens!
great video
Mine has 2 prongs new one gas 3 but both say the same can I still use it?

Super Frugal to the rescue

Great video. My problem is that the fan turn on but after a few minutes 10-15 minutes the fan turn off and compresor keep on. Any idea?
Probably a bad fan motor. But I would try the cap first to be sure.
@@frugalprepper but the fan when in the beginning works perfectly. But after a minutes turn of. I understand that the capacitor it is to turn on the fan. But which capacitor or part keep the fan on?
@@byshotmediait’s your Fan Motor for sure. I had the same exact problem.
Can’t you just leave it like that? Why do have to replace it back to one capacitor?
Sure you can leave it like this.
G'day,
Cool !
Or, at least, a lot cooler than when it was running Backwards...!
;-p
Thanks bud
Any time!
what 2 pole run capacitor AC unit mean ?
Well you have a 2 pole cap that runs on the Compressor and a 2 pole cap for the fan. The Dual cap has one terminal in common and the other are compressor and fan. There are also tough starting caps and relays on some units.

Yes you can do this permanently. I didn't replace this one for like 3 years until the other side of it died.
Planned obsolescence, what a wonderful thing these manufacturers are doing nowadays. So considerate of these corporations, huh?
I have a question. My unit has 5 wires, 3 for C, 1 for H and 1 for F. So, i bought 2 capacitors of 25f and 6f for the unit. Should i connect the herm wire to the bigger capacitor or the smaller one?
The compressor (H) will be the larger capacitor. The fan (F) will be the smaller capacitor. The commons (C) will go to the other sides of those capacitors bridged together.
@@frugalprepper so 2 commons to the large one and one common to the smaller one right? and the capacitor should be Bridged together
You should do research on how capacitors work, what “common” is, and read the wiring diagrams, getting an all round understanding of the electric is the only foolproof way to know what your doing is correct for your unit
Common will always connect the two capacitors together, or you can run common from them both directly to the contactor, there’s different ways of doing things so the best way is to have an all round understanding of how they work and why
Most residential AC compressors use ATLEAST a 30-45mfd capacitor to kick the compressor on, and the fan side will usually be 5mfd
If your fan has two brown wires (solid brown and brown/white) do you just attach both browns to the 5 MFD Run Capacitor?
I'm in a similar situation but my universal fan replacement motor has 4 wires total (2 being browns)
Yes just one brown to one side and the other brown to the other
Good, I wasn't sure.
how would to wire a 2 wire hard start kit to that ?
If you are just putting in a extra cap like a 145 to 175, you can just put it in bewee the hot and the herm connection. If you are putting one in with relay, you would have to follow the directions that come with the kit.
@@frugalprepper ok.. what if there's no space on common van I use piggyback terminal?
How about a universal fan?
You will have to see the capacitor rating for the replacement fan.
Can you please explain why the other purple wire is connected to the hot?
Im trying to do the opposite. Thanks.
