Those aren’t supposed to be round on top.
For an european that sounds unbearable, but i have to translate to celcius
Yep, if your condenser unit outside just won’t turn on it’s always a good idea to check this capacitor. I think it was just last year that I replaced the one in my unit installed in 2015. I went through a few capacitors with the ancient system before that!
This is me, today. House is 88 F. Service won’t arrive until Monday.
Last year mine conked out during a 100+° day. I tried everything! I’m talking cold(ground was still hot so it was actually a cool shower) then frozen water bottles in my pits, crotch, and neck. I ended up going to a cheap motel for the night and discover my door knob was actually hotter inside than out.
Yeah, I identify with this. Outside is cooler than inside. I would do a motel but 3 dogs is a no-go for places near me. They won’t stay outside either, silly things want to be inside with me.
mine went out in July in Phoenix, AZ. The 3rd closest Ace had 1 in stock for my unit.
I’ve seen so many HVAC repair trucks on the roads this week.
As a refrigeration/HVAC guy, the past couple months have been hell. Most of our crew has been working over 60 hours a week for two months straight and we still aren’t even close to keeping up. We’re having to heavily triage calls. Hell, I just finally got dispatched to a prison the other day where aparently a whole cell block had been mostly without AC for an entire week. Normally a call like that would get someone dispatched same day but we just don’t have the people. I work with guys that have been doing this for decades and even they say that the current volume of tickets is unprecedented.
When you go upstairs do you constantly hear “Give Me Just One Night” or something in the background?
I do but unfortunately the announcer just keeps talking right up to the post.
My 20 year old AC breaks once a year, at this point it’s the ship of theseus. One year it’s the capacitor on condensor, then condensor fan motor, then fan motor that circulates air instead, then circuit board that controls all HVAC functions, then capacitor for circulation fan. Every year, when the heat hits strong, something breaks, I have become proficient in diagnosting HVAC system at this point.
If you’re going through multiple condensers a decade you need a new air conditioner. From a different manufacturer operating on a different continent.
A quick tip if you want to minimize the number of repairs. If a motor dies, replace all the start components as well. The old ones might be fully functional and even test good but when the motor quit it likely weakened them. Similarly, if one start component fails then just replace all of them for the same reason. A failing start cap or run cap can really beat up the start relay so even if it works temporarily, it will often fail later. Also if you notice that you keep having to replace start components for a particular motor then that motorcis starting to fail. We see that all the time with compressors in particular. A hard start kit can help in that case but it shouldn’t be considered a fix.
I feel so dumb sitting here thinking you were talking about the connections. Like yeah they’re supposed to be round for ease of insertion. But also could tell something was off cause they usually point in parallel directions. Then I noticed the black dome they are attached to.
Please bring this to a proper site for disposal, that thing is like a flaming poison bomb at this point.
It probably just swelled when it got hot now that it’s cooled down it’s probably in a little bit of a vacuum state.
Hopefully, but is it really worth the risk?
Just a couple grams of DMF in there no big deal it’ll put some hair on your chest
Who needs a liver anyways!
This was me on Sunday… And then also on Monday after relacing the cap and then realizing that the fan motor was janky (which might be what caused the cap to fail)
realizing that the fan motor was janky (which might be what caused the cap to fail)
Yep, that is often the case. I’m a hvac/refrigeration tech and I’d say about 20% of the time I have to replace start components, it’s because the motor in question is starting to fail.
36.5°c for people who use sane units ;)
Thank you! 😃
As much as I like the metric system, temperature in the world is the one place where I prefer Fahrenheit. Having to care about decimal points on a thermostat just seems like trying too hard. “Oh honey, could you turn the thermostat down to 21.1C?”
You know that 100 is hot as balls. You know 0 is cold AF. 0C is 32F. That’s not really that cold, I’m shoveling snow in a t-shirt. 0F is really that cold. It is almost more akin to a percent of comfort scale than a measurement of temperature.
It is an interesting thought experiment though, as anyone using a given measurement scale gets used to it over time. I’ve been doing dual for a while to better intuit fuzzy translations in my head without having to run a formula every time.
Just an opinion of course, and not trying to have some flagrant discussion. I’d gladly switch to Celsius if we ever finally left Freedom Units. Thus far, the only places you see it in the US is in science, medical, and pop companies selling 16.9fl oz (just shy of 500ml) beverages instead of 20, so they can milk their bubble sugar water for all the profits.
No one calls out decimals in Celsius. Unless you are measuring your kids fever. 38.1 vs 38.5 vs 38.9 you know that it’s time to ready the metamizole if it keeps creeping up like that
0°C is the frost point of water. If you know it will dip below that during the night, you can prepare your plants, driveway, kids (I’m sorry my love summer is over), pets, clothes, etc the day prior.
-40° is -40° though, doesn’t matter if it’s F or C. The best part of both scales.
Nah, I agree 100%. Celsius is wonderful for computers and science, but the human-tolerable range is far too small. Fahrenheit is a human-based scale, with 0-100 basically corresponding to a percentage of how much heat a person is able to/forced to hold onto. At 0, you’re not really able to hold onto any heat; you quickly reach hypothermia. At 100, you’re forced to keep nearly all of your heat, and are only able to vent trace amounts; you quickly reach hyperthermia.
It turns out, people function best when they’re keeping 40-70% of their heat (depending on how they’re acclimatized, which is determined by how much brown fat they have), so those are the temperatures that are most comfortable for us.
You do realize the reason fahrenheit is set up that way, is based on the human perception of temperature. 0-100 is the general range or cold to hot. Of course some inhabited areas end up outside that range a bit, because humans are adaptable but generally speaking it allows for far more graduation in every day real world scenarios. Metric is good for science, but not ideal for casual everyday usage of hot and cold.
Your body doesn’t really care what the boiling point or freezing point of water is. But you should and generally do need to preemptively plan for environments outside the fahrenheit scale.
If that was true, then we wouldn’t see people bitching about the cold while I’m out in a t-shirt and jeans in 50°F weather. Seems fucking stupid to base a measurement system on something so subjective.
You do realize the reason fahrenheit is set up that way, is based on the human perception of temperature. 0-100 is the general range or cold to hot.
That is not why fahrenheit works the way it does. This is something Americans have appropriated as a silly and poor excuse for using it. “cold” and “hot” are completely arbitrary and subjective terms, and the 0-100 range is as arbitrary.
Metric is good for science, but not ideal for casual everyday usage of hot and cold.
That will come as a surprise to the billions of people using it every day for exactly that purpose. You are projecting your own ignorance over billions of people, because you yourself have no idea how it works.

You’re entirely right, but it’s fun to trigger people like you with a couple words that ultimately mean nothing.
You are projecting your own ignorance over billions of people, because you yourself have no idea how it works.
You mistake ignorance for simply not giving a fuck. I know what Celsius is, I know how it converts, I just don’t care.
It’s very entertaining to be able to trigger people at will to crawl out of the like bugs and talk shit online, wasting their time on a topic that doesn’t matter in the slightest. It’s usually the Europeans, they seem to have a superiority complex about this specifically for some reason and love typing at length about it. Most other countries outside the EU region don’t bother, probably because it doesn’t matter.
Also, here’s the obligatory reminder to the Europeans that the US began using metric in 1866 and officially switched to the metric system in 1975, it just wasn’t made mandatory to switch, so most didn’t. Because it doesn’t really matter for daily life which system is used.
Ah, well here’s another one of those down votes you were looking for.
Side note, I’m American. After getting a mechanical engineering degree is was clear to me that metric is just better. Maybe it doesn’t matter to you, maybe it doesn’t matter to most people, but if you actually have to spend time thinking about this stuff then it starts to matter.
Epic projection comment. How very much your multi paragraph reply screams “I don’t care”.
You sure write a lot for someone who just doesn’t care
Lots of downtime at work at 3am. Might as well poke the Europeans since they’re awake.
Oh, just can it, American.
Hey. Remember when the beagle spacecraft totally slammed into the Martian countryside because someone used imperial units? 2 year wait for some good times.
slammed into the Martian countryside
At least it avoided the Martian urban areas.
Your body doesn’t really care what the boiling point or freezing point of water is.
Yes it does.
Maybe Fahrenheit is really for tardigrades. Those don’t really care about the freezing temperature of water.
You do realize the reason fahrenheit is set up that way, is based on the human perception of temperature. 0-100 is the general range or cold to hot.
You do realize that Celsius is set up based on known, objective, & measurable data points instead of subjective things like “hot” and “cold”.
No, the human perception of temperature thing is a myth. Originally 0F is the freezing temperature of a brine solution, and 90F was Fahrenheit’s estimation on the average human body temperature, and then the scale was adjusted so that it fit in better with Celsius reference points (freezing/boiling points of water).
Reference: https://en.wikipedia.org/wiki/Fahrenheit
So it’s all a hack.
Like half of the things American.
The 9 and 100 in F is a completely random range, where 0 is a random solution freezing point and 100 was an estimation. Tell me how it’s better than C, tied to water, the main stuff we all need to live in this planet and probably also for aliens in other planets.
I personally would use Kelvin for science, Celsius is much more useful for everyday things like whether it will rain or snow, whether the paths will be icy, how hot it will be according to the weather report and how hot to make stuff when boiling water or cooking. Kelvin is great for not having negative temperatures which don’t make sense.
At last it’s an inexpensive and easy fix. Just buy another capacitor with the same specs and swap them out. Better yet, buy two! Keep one as a backup.
If there are other start components then those should also be swapped. One component failing can weaken the others, especially the start relay.
Don’t buy an electrolytic capacitor as back up and store then over a long time. They will degrade and will be bad when you finally need them.
MKP/MKT capacitors are an exception since they don’t degrade the same.
Eh, they do age but a spare capacitor sitting in a likely climate controlled building and not being used isn’t going to age nearly as quickly as the one in use likely in the outdoors. Will it be as good as a brand new one? No. But it will be damn near as good and it will be on hand when you need it.
At the same time though, if a motor kills start components often enough that you need to keep a spare on hand then there is something wrong with that motor or your power source.
Yeah, I bought one to make sure that was the only problem. It just came back up so, now I’ll pull the furnace apart and find what size it uses for the blower keep them both on hand.
They can blow on their own but chances are you have a junk contactor or a fan that draws too much amperage.
It’s also possible a critter shorted the contacts. Happens all the time in Florida. Usually the fried lizard is still there.
True enough.
3 year old unit :(
Then it certainly shouldn’t have failed yet so either high cycle rate or high draw.
Clean both coils and keep watch on how often it runs and how long it stays running for a couple weeks. Also if you still have a analog bimetallic thermostat those can fail and cause rapid cycling and if the compressor isn’t smart enough to delay they can cycle themselves to death.

It’s on an ecobee which appears to be behaving, pulling data from homeassistant on emporia power, it seems to be pretty chill.
she’s 1.5 ton pulling 1300 watts while running which actually seems low to me.
As much as that sucks, you clearly already know the fix and are working on it. Grats to you for having the skills bro. Please work safe, 2 phase electricity doesn’t play around.
Your upstairs must be literally boiling.
Or damn near freezing
After replacing the capacitor I set the thermostat to zero Kelvin
Only a Sith deals in absolute zeros!
It’s not a fix an HVAC tech would tell you how to do.
Nah, “freedom” units there’s a whole other human’s worth of temperature before it actually boils.
What is that?
It’s a large capacitor. They are used in those big outdoor AC units to kick start the
fancompressor. Being outdoors and subject to large temperature changes and vibrations for years they inevitably fail.https://static.homeguide.com/assets/images/content/homeguide-technician-replacing-ac-capacitor.jpg
They are to help start the compressor, not the fan. Anything with a compressor will have one, like your fridge.
The fan motors will often also have them. It just depends on the size and type of motor. Most big AC motors use them unless you’re dealing with 3 phase power.
They are used for the evap coils fan as well.
Ah, you’re right. Got it mixed up with furnace fans which have smaller caps.
I’m assuming that it’s some sort of component from the air conditioner, but damned if I know what it is. Looks like power plugs on it, and someone else mentioned “caps”, so maybe a capacitor, though I wasn’t aware that there was some kind of plug standard for large removable capacitors.
kagis
Yeah, this capacitor looks similar.
EDIT: Apparently air conditioners can use large capacitors:
https://www.amazon.com/Capacitor-Conditioner-Multi-Purpose-Capacitor-5-Warranty/dp/B092ZQ3Y3N
Capacitor for Air Conditioner 5 uf MFD 370 or 440 Volt VAC, Multi-Purpose Round Capacitor for AC Motor Run or Fan Motor Start or Condenser Straight
EDIT2: Oh, I bet I know what it’s for, given the “Fan Motor Start” and what I assume is a misspelled “Condenser Start” text on the Amazon listing. Some hardware will draw a lot of juice when starting up. Laser printers are prone to this, for example. The references above are to mechanical things, moving components, and maybe one need extra power to overcome static friction, to get the parts in motion initially; once moving, they face (lesser) kinetic friction. One option is to just draw a ton of power from the line, but then that increases the peak power demands of a device. Another option, gentler on whatever circuit or external power source is providing the power, is to charge a capacitor for a bit and that’ll let you create a big surge of available power for a moment without having to have higher peak demands on the external power source. Adds to device cost, but limits its peak draw.
Not quite- these motor capacitors provide a phase shift for a second set of windings. Without it, the motor will just hum and not rotate.
You are describing bulk or filter capacitors that go from supply to common on a DC circuit, parallel to the load. These motor caps are on AC and in series with the load.
Gotcha, thanks!
Until you can fix it, open the windows, curtains and blinds at night and shut them during the day.
