AC fan not working - how to repair broken HVAC Run Start Capacitor - air condition

[rbu2m]

In Florida it’s getting harder to buy them from the HVAC distributing company since they told me that they will longer sell them to home owners. They only sell them to Licensed Contractors

[iesuck]

@rbu2m interesting.... but its only a capacitor... i wonder why they enforce such policies...

[hvacdexter]

Should check the amps on that unit. Those caps tend to blow because of high amps or low voltage. I come across a lot of burned caps simple because the condensor coil is extremely dirty causing the compressor to draw too many amps. Then POP goes the cap.

[iesuck]

@hvacdexter thats interesting to know. my condenser coil was dirty, but it was was a record hottest temperature too. I am sure both combination didnt help.

[TheTreetop1988]

As a tech my self make sure you use a resistor or a insulated scewdriver to discharge terminals. More than a few times ive got a nasty shock.

@Ajax2341 Hahahaha

[Ajax2341]

Thank's that makes more sense.

[Ajax2341]

Could I find that part at Walmart ?

[iesuck]

@Ajax2341 no, you can't. Look for a HVAC hardware store. In the mid south we have a store called lock supply. you can also buy it online at Amazon, digikey, mouser, etc...

[ThePariss333]

@iesuck I have a question,I dont know if you can help me,but maybe you can: exactly that place ( A/C fan) its close to a room, from that room,i hear a bad noise,when the A/C star, I mean, start right,but,then, I heard a weird noise like craking,knoking,I dont know how to explane.it cool inside the house,perfect,but from the room,principally at night, I can hear that noise. an A/C guy,told me it was working on pressure,maybe luck of gas or some thing. can I cover that part on winter too or not?

[iesuck]

@ThePariss333 I think you are asking me 2 questions.

Question 1: Whats that noise? My guess it sounds like a loose bearing. Search youtube for HVAC fan bearing being loose.

Question 2: Can you cover it during winter? Yes, you can when its turned off. Its called "Air Conditioner Covers"

[01Commenter10]

Do you know where the capacitor is for the inside air handler..?? The inside air handler blower motor does not spin...

[uncreativeranter]

silly Q but if u had a bad neighbor & they water hosed your outdoor fan is it possible that it would damage or is the outdoor unit designed to withstand water? Its an Akai reverse cycle spilt air conditioner. When I turn to heat the outdoor fan works but theirs no air coming from indoor unit and when i switch to cool air then the outdoor fan stops working but the indoor fan works. I hear a click like your thermostat click maybe also the electricity hum turns on & off compressor? or capacitor?

[Defcon458]

I love opening a unit and seeing a swollen run cap. And don't tell folks to put their disconnect back in while working on the unit...bout time they accidentally restore power and jolt themselves.

[a92123]

Dam i dont even have to put my meter on that... replace the capacitor things about to explode

[DFWNubianKing]

THANK GOD FOR THIS VIDEO!!!! I have a Carrier HVAC unit and my unit went out just like you described in this video. After taking off my panel I discovered I had a dual run capacitor 40/5 370VAC. So, I go to the grainger.com website to locate the part and to find a local store I could visit. I spent $17.62 for a new one. Installed it, reconnected the wiring correctly and the unit is back to normal!!!! I refused to call a repairmen for this fix. I'm glad I did my own homework on this one.

[headscratcher99]

You mention that by pulling the breaker, it removes the power from the AC. This is true for the high voltage, but there still may be 24 VAC coming into the outside unit from the inside thermostat control.

[iesuck]

@headscratcher99 That is true. I did turn off the AC at the thermostat too. Always be careful when you mess with electricity.

[skyym3]

you just fixed your a/c unit for about $15.00 to $20.00 for the cost of the dual run cap. An a/c company would of charged you from $200.00 to $500.00 for that exact same fix. I know because I own an a/c company and have been working in the HVAC industry for over 26 years now. 6 of those years were in Dallas, Tx. and the 19 years were in Phx., Arizona.

[Defcon458]

@skyym3 Who in the hell is going to charge $200 for a run capacitor?! $500 ought to be considered THEFT. WTF kind of business are you running?!?!

[skyym3]

@Defcon458 You are not very wise with the ways of the HVAC industry, are you? I don't know what kind of "knowledge" you have, but I sure can imagine. Just watching you work on this video shows me you don't know much. funny thing when you own a business, is you have to pay the Gov. for thiese things called a license. Oh ya lets not forget the business insurance, advertising, gas, vehicles, your workers and there health ins. workers comp. shit loads of overhead, and I warranty my work.

[Defcon458]

@skyym3 Watching ME work? WTF you talking about, bud? Had one too many cold ones? I know exactly what you are...you're just another piece of shit ass AC CROOK like the rest of them. Wanna know how I know? Because I AM THE ONLY AC TECH IN THE WORLD WHO IS HONEST. Maybe if you were sleeping instead of drinking and talking shit on youtube at 4AM you'd accomplish something. I'd love to chat but I gotta go drop some other scumbag AC guys like you in the dust. I spend every day busting you pricks.

[skyym3]

@Defcon458 I also did not say that I charge these prices, if you could read and comprehend properly, I said companies charge these amounts. I actually charge about $85 for the dual cap and $68 for the service call. I also do a hell of allot more than what u did. You change a part, that is it. You should not even have access to that part actually, unless you’re licensed. You get hurt or your little finger burned and I promise you, you will sue whomever u can for your stupidity. don't reply

[Defcon458]

@skyym3 AND LMFAO @ "Dont Reply." Just so you know, I will NEVER obey some prick like you...the fact you told me not to reply is t he only reason I replied. Suck it! You ain't got shit!

[MARICELA1001]

I was watching this video and look so simple to change, and I want to do that, but I found 2 capacitador when I did open, one a normal side and other small, I was looking for the model is a Bryant 593CJ048-B on internet and in the generic they ask for voltage, what is 208-230 my question is, how I can find the rigth capacitador ?? if I take with me to the store supply, how I will know to put back whit the rigth cable. please Help me.. Maricela Im woman lol

[iesuck]

@MARICELA1001 You could use a DMM and check to see if both capacitors are good or not. If either one is out of its limit, then you should replace the bad one. e.g. (youtube.com/watch?v=_vhiCfIwF­Kk&feature)

There might be a model number on the capacitor. If not, then there are 3 important specs to follow. First is the capacitance (e.g. uF, typical rating for residential is 35uF), second is voltage (typical rating is 250-300V or higher), last is temperature but most rating should work.

[MARICELA1001]

@iesuck thanks so much, I did check and both are good, so probably is the fan motor, I did disconect all cable, and I don't kknow how put together. is any video about that/??/

[mikie2501]

It's always a beautiful soud when it starts up! Always check the voltage with a meter to ake sure i ed[s GL :) Michael

[ameichholz]

Just had this replaced 20 minutes ago, of course I wouldn't have felt comfortable doing it myself, but I'm glad I found your video, I have a Goodman as well, I've been overall happy with it. It's about 8 years old.

[HCVguy93]

Good job replacing that, but typical in those type units. Those are Goodman, the worst POS units you can buy. Those units are probably nothing BUT trouble.

But still good video.

[Loydm30]

Thanks a lot for posting this D.I.Y. video, i just bought a house with old A/C system and after 2 weeks i found out that compressor / fan outside stopped working. i hear that theres a capacitor you could change to solve the problem, so i did some research on Youtube BAMMM !! i saw your video, save my money, man you are awsome :)

[aznpink7]

Hey thank you so much for posting this video, it was very detailed and helpful. We tried it and it worked perfectly. Thanks a ton!!

[iamafractal]

the capacitor is capable of holding a dangerous charge, so it's very important to drain it before you touch anything. a relatively safe way is to take a light bulb connected to a socket and two wires, and just touch the wires to the different leads on the capacitor.

[iesuck]

@iamafractal thx for the warning. I placed a short note on it to warn people about that. Thanks!!

[lmgtech]

@iesuck

My 25 year old Amana window AC's compressor is not starting (it try to start and can feel vibration and sound ) and fan motor has delayed starting also running at slow speed.Is it a capacitor failure.

[iesuck]

@lmgtech you need to measure the capacitance of the capacitor with a DMM.

[WiseInfant]

@iamafractal The easiest way to discharge a capacitor is simply toutching a screwdriver across the terminals. Make sure you are holding the screwdriver by its insolated handle.

[stevebardocz]

The most tested fine so I was pretty sure it was the cap. Grainger confirmed a bad cap. I replaced and put it all back together. Fired it up and it started up just like yours! I was glad to hear that noise! Thanks for the posting!

[stevebardocz]

Thanks - this was my exact problem and it helped to watch someone run through what I needed to do. I suspected the capacitor or the fan motor and was rooting for the capacitor since it was $18 compared to $152. I went to grainger and they were able to test the cap for me (my multimeter did not have a uF test setting) and had mine in stock. I tested the motor for ohms (a failed motor will appear with super low impedence because usually the windings are shorted together).

[Jpink239]

having the same problem

[TSXKid]

Thanks for this post.. Helped solve my problem (wiring related)!!
