Mini Split Air Conditioners: Need help identifying a RUUD condenser dual-run capacitor

Thu, 21 Dec 2023 16:28:29 -0700

I need to replace a 31 year old condenser dual-run capacitor in a RUUD air conditioner (model UALA-036JAS). Unfortunately the existing capacitor has absolutely no markings on it. When checked with a Supco capacitor tester it reads "open" on all connections. I called RUUD/Rheem and they specified a 40/5 uF replacement. I contacted Bristol who makes the compressor (but has been bought and moved to Thailand) and they spec'd a 35/5 uF.

Obviously I don’t want to install the wrong one, so any help or thoughts on this would be greatly appreciated! -Steve

LSA5AU5A: LG Air Conditioning showing Lo in display

Thu, 21 Dec 2023 16:28:06 -0700

My LG split (non-inverter) AC is frequently switching ON and OFF and sometimes changing the cooling modes on its own. Also it showed "Lo" on the display of the indoor unit! What does this mean and what should I do to correct it?

LSA5AU5A.ANLG (II) 2015 model

I usually set it at 22°C. And its summer now so room was definitely hot!

Cannot regulate the heat

Whirlpool Model ACE244XSO The heat will vary 10+ degrees------ up and down without moving the thermostat setting. Probably the thermostat but I haven't found one for it.

Central Air Conditioners: Changing Refrigerant in Central Air from r22 to M099

Thu, 21 Dec 2023 16:40:45 -0700

My plumber has been trying to sell me a whole new HVACstating that r22 has become to expensive and hard to get. But after a little research I found a supposed replacement refrigerant

DuPont

Isceon MO99

Looks like 25 lbs will run about $220.00 + $39.00 shipping on Amazon.

Then all you do is recover the r22 from the current system, check the seals and replace the gas. The law says this must be done by a licensed professional and that is fine. He then has a lot of r22 he can sell to someone else.

I also know that if I know what the problem is and the solution, I protect myself from service professionals that may want to sell you something you don’t really need.

My immediate question is how do I find out or calculate just how much gas my system needs?

@ladytech @oldturkey03 do you know anything about this. It could be a very important answer for lots of homes and a whole lot of $?

Central Air Conditioners: Where is the 2nd capacitor in my AC unit?

Thu, 21 Dec 2023 16:40:20 -0700

I bought a spare motor run capacitor for my ac unit - it is found inside the service panel. It’s an American Standard, model 4TTX6060E1000AA. From the wiring diagram I found on line, I know there is a second capacitor. It will presumably be for the fan? Can anyone tell me where I can find it? Is it internal to the fan?

Would these work and which might be best please?

Air Conditioning: Is it legal to add R22 to my own system?

Sat, 20 Jun 2020 03:59:48 -0700

So I noticed that you can purchase R-22 refrigerant from eBay which I assume is the recycled stuff. If I'm understanding correctly you do not need a license to buy the recycled R-22. Is that correct?

If it is legal to buy without a license from eBay then my next question is can I add it to my own system without any EPA license?

I'm in Missouri, not sure if there are restrictions from different states or not.

Thanks!

So my Tempstar AC is going to be 19 years old this year. It kind of struggles to cool the house, but it gets the job done. Should I look for a whole new hvac unit (including heat/AC)? Or wait till this one dies on me? My house is 3200 sq ft.

Air Conditioning: Carrier Outdoor Condenser Fan Problems -- Spins, but no Cold Air

Mon, 23 Jul 2018 20:34:09 -0700

About 1 month ago my Carrier outdoor condenser fan froze in the middle of the night, the Texas heat, lack of lube, and 24/7 operation killed it. I went out, powered down, took it apart, broke the shaft loose and lubed it, until I could turn easily with fingers, and powered it back up, started right up, been working and blowing cold air ever since.

Today, in Austin, it hit 112F+ at my house a few hours ago, the motor just shut down. I went out there, and manually gave it a little spin, spun back up, and is spinning well.

I suspect the run cap has had it too, so that AND the motor need to be replaced. But, its 10pm, nothing is open, house is 90F inside, and the AC is NOT working?

Something happened? But what? The system was cooling very well, it was 74F in here, 112F outside, then the motor stopped (as it does periodically when it gets the temp ahead of the setting), and then it couldn't start back up. But, how do I go from cooling fine, to NOT cooling fine from one minute to the next?

The motor is spinning, I tried turning power off, resetting, checked the controller in attic, LED is running good, no error codes.

So, I am at a loss -- the motor needs replacement, and the run cap, but, it running right now, and the system should be cooling, but its not. What else could have changed in a matter of mins?

I could understand if over 2-3 weeks it got warmer and warmer, need coolant, but it was freezing air, now it warm.

I am an EE, not an AC guy by any stretch, but I assume maybe a cut off, safety of some sort was tripped, but a power cycle, and that should do it right? And this carrier doesn't seem to have a RESET on the condenser, but even if it did the motor wouldn't spin as it is right now --

Please help -- I am dying here, and have a ton of computer work, PCs are over heating as I write this...

Thanks --

Air Conditioning: Stripped screws to A/C breaker

Fri, 24 Mar 2017 13:39:17 -0700

I am trying to replace a breaker for my A/C and I can't get the screws that hold the wires in the old breaker. I think both of them are stripped. I bought a cordless drill this morning on the way to work and it is charging now but if it doesn't work to remove the screws I am wondering if I actually have to have these screws out to get the breaker out. It seems like the screws are holding the breaker in as well as holding the wires in the breaker. I am asking because if they are not holding the breaker in the panel then would it be possible to take the breaker out and cut the wires off close to the breaker and peel down the insulation and put them in the new breaker? This is Houston, mid-March, it's getting hot! HELP!
