Haier Portable AC | Buzzing and Not Cooling - FIX

One of the most common problems with a compressor that won't start is a bad run capacitor. In this video I show you how that fixed my son's portable AC problem. Other issues related to an AC compressor that won't run could be refrigerant leaks, burned electrical components, or a failed compressor.
When buying a new capacitor you may not find an identical matching capacitor. It's okay if the replacement capacitor has a higher voltage number. What is more important is to match the capacitance number (uF), the shape of the capacitor (round), and the number of poles at the top (where the connectors go). In my case it was two pole capacitor, which means it had two separate round parts a the top, each with multiple wire connectors.
Take a photo of the way the original capacitor is wired so you can install the new capacitor the same way.
There is no guarantee that changing your capacitor will make your AC cool again. If that does not work, other things you can try include: clean your coils with coil cleaner (see related video link below), check the circuit board for any burned components, check for refrigerant leaks by spraying soap + water on the coils when the AC is on to look for any bubbles indicating refrigerant leaks. If you have your capacitance meter, check the square-rectangular looking capacitor to see if the output is normal or low. When the compressor is running, it warms up, turn on the AC (set it to cool) and touch the compressor with your hand, if it doesn't warm up it's likely dead and needs to be replaced.
Troubleshooting list:
Clean the washable filter.
Clean the coils.
Replace capacitor(s).
Check for leaks with system running using soapy water.
Turn on unit, touch compressor, should be hot if its running.
Turn on unit, listen for fans, should be running.
Turn on unit, touch copper lines, one should be cold (and sweating) the other should be hot if compressor is good.
Visually check motherboard for burned components.
Visually Check wires for any loose connections.
Visually Check connectors for corrosion (rust), clean off any corrosion with wire brush.

[@wilsont1010]

@@ChavezDIY The compressor was working normally giving out good cold air and suddenly it became completely quiet when the air-conditioner was switched on the next time, is this likely due to the capacitor issue? As you have said in the video there will still be starting sound coming from the compressor. But in our case no starting sound can be heard, what are the chances that it is a capacitor issue?

Purchased: August 2022 - still works GREAT! kzbin.infoUgkxxsUnXhGsSJLim_XnMHyQK0u3XVaW-CGn I live in a studio and during the summer it gets scorching hot - really old building with no ac units. I can’t express how EASY it was to install.This unit has been a life savior during the summer and some days during other seasons where it can still be a bit warm at night. In this small place is my friend, a husky, poodle mix and myself. We need AC - lolI don’t use the dehumidifier option - I’m not sure if it will leak in my house, since I did not install the small draining hose that came with it. May look into it late but I don’t worry about much humidity in the apartment.I don’t understand why the negative reviews since all things mentioned, I personally did not find issues with. Definitely worth it!

Hi, I took my PAC apart to clean it up, this was after a major storm and Power Surge in my Unit. Everything is working fine on it except it's not blowing Freezing Cold Air. No Leaks, Compressor Works, but I don't think it's getting all the Power it Needs, so I think it's the Run Capacitor that needs to be changed. Thanks For your Tips and a Great Video, Chavez. I will let you know if this fixes it. Take Care.

[@ChavezDIY]

Good luck! Hopefully replacing the capacitor gets it running.

[@robertapark4392]

I have a question about cleaning the coils, what if I don’t have the fancy spray like you have.. (not able to go out and purchase)

[@ChavezDIY]

Then use any household cleaning spray in a bottle and rinse it off with water after 10-15 using the spray bottle. Water and soap is better than not cleaning your coils at all.

[@sunkistv]

i see that capaciator original says "protected" and the new ones not "protected". is this because there's already trip wire in the cord section? so doesn't need double protection?

[@damian3182]

Greetings, my ac fans go to low speed as the compressor is trying to turn on, I hear some low electrical hum but I can't tell. Everything is clean and I even poured out both trays of water. At this stage I'm going to follow your tutorial here to see if its the capacitor. Is this the symptom your ac was having? Did you hear the fans go to low speed why the compressor was trying to turn on but doesn't?

[@ChavezDIY]

My AC was making a buzzing noise, so yeah there was more noise than just the fan. I don't remember the velocity of the fans at the time the unit wasn't cooling. I believe the sound the unit was making is included in this video, but you have to use headphones and turn up the volume to hear it. So the compressor has a capacitor, the round cylinder one, and the fan also has its own capacitor, its a rectangular cube looking one. Both capacitors have the capacitance range listed on them. The best way to approach this is to get a capacitance meter and check the capacitance of each capacitor. In the video description I have a link to a $20 capacitance meter on Amazon, its the cheapest one I could find and it works well. As long as you have fans and ACs in your life, you will need a capacitance meter to check the capacitors in case they fail.

[@damian3182]

@ChavezHobbies I have a multimeter that has an option "200m", when I have it set to that I get a reading like yours where it starts at 3.1 then drop to the .3 range. Does my multimeter have the ability to get a reading?

[@ChavezDIY]

@@damian3182 Budget multimeters don't have capacitance readings. The symbol for capacitance is uF, on some multimeters its listed as uA. I have two multimeters and neither can detect capacitance, that's why I had to buy that specific multimeter just for capacitance. You can buy a multimeter with capacitance readings but it has to specifically say it. You'll have to read the manual to check the capacitance with the meter.

[@user-je1ch6io2r]

Hi I have changed the capacitor the exact way, cleaned the all the coiles but still not cold air, any suggestions please 🙏 Thank you

[@ChavezDIY]

Does the compressor turn on? Do you hear it running? If the fans are running good, it could be compressor failure or a leak of refrigerant. If you want to check for leaks, with the cover off run the AC and spray soapy water on the copper AC lines that go through the coils.

[@gregsmith3623]

My motor that pushes the heat out of the hose that goes out the window isn't working, would the capacitor cause this? I liked your video and would be grateful for your answer for my problem.

[@ChavezDIY]

Sounds like your fan motor is not working. The capacitor I replaced in this video is for the AC compressor. The fan has its own capacitor, but it looks rectangular, you can actually see it above the cylinder capacitor in this video. Your best approach is to get a capacitance meter and check the capacitance of both the compressor capacitor and the fan capacitor. I have a link to a capacitance meter in the video description, its one of the cheapest ones you can buy and it works well. You're always going to have an AC for the rest of your life, so the capacitance meter pays for itself.

[@gregsmith3623]

@@ChavezDIY thank you I'll check it out.

[@ChavezDIY]

You can see the fan capacitor right above the compressor capacitor at 4:20 in the video.

[@isa5537]

Mine blows semi warm air no buzzing. Do you think its still the capacitor if it doesn't cool?

[@ChavezDIY]

Sounds like its not cooling. It could be the capacitor. Try it out and see if replacing the capacitor helps. Check the video description for more information.

[@nu.perspective]

The compressor does kick in on my portable AC, but no cold air. Could it be refrigerant issue?

[@ChavezDIY]

These portable units don't have a service port to add refrigerant. I would start with cleaning the coils (check the video description for a link on cleaning the unit). If the unit is low on refrigerant that means you have a leak somewhere. With the unit open but still connected, run the AC and spray soap and water on the copper lines to and from the compressor and evaporator to look for any leaks. They will show up as active bubbles if you have a leak. If no leaks and you cleaned everything, I would check the capacitor. You will need a capacitance meter to check the capacitor, a link to the cheapest one I could find is in the video description.

[@kitn.6130]

is it normal to hear the buzzing sound still? i have a toshiba brand new. its cooling fine but it's making buzzing noise

[@ChavezDIY]

It's normal for compressors to make a buzzing noise when they're running You can hear it in my AC after I fixed it. The compressor has rubber feet to try to decrease noise from vibrations but sometimes the vibrations get through and shake the outer case of the AC.

[@kitn.6130]

@@ChavezDIY I research everywhere online and everyone is complaining about the compressor noise. it seems like a normal portable ac compressor sound. Some says it goes away after a few days or weeks of normal use. Although I think the rubber that's supposed to reduce noise is probably loose during transportation. It's sad. It's so loud

[@ChavezDIY]

@@kitn.6130 All compressors make noise, but some are louder than others. With window ACs the compressor is right there in your room, haha, you'll be hearing it. I had a Honeywell 14K BTU portable AC unit that was louder than this Haier 8K BTU unit in this video. I also have a Frigidaire 5k window unit that is kinda quiet compared to my LG 6K BTU window unit.

[@Dcttgo2]

My compressor will kick on, the after a while it will turn off, the air won't be cold for a couple minute, then it will come back on and the unit will shake pretty hard. Could this still be the same thing in the video?

[@ChavezDIY]

When was the last time you cleaned the coils on the unit? If the coils are dirty the unit could shut off due to overheating. Here is a video showing how to clean the coils kzbin.info/www/bejne/op-tfHWfYtV1lZY If the coils are clean, then yeah the next thing I would look into is the capacitors. There is more than one capacitor, there's a square one that shows up inside my unit, that was going to be my next item to check. You'll need the capacitance meter to check your capacitors. $20 for the one I have in the video, link in the description. Its the cheapest one you'll find and you can resell it after.

[@christianfoster8400]

I have a portable unit that the fans won’t come on but the compressor is working. Any idea?

[@ChavezDIY]

There's two capacitors inside the AC. One is the cylinder shaped one that I replaced in this video and the other is rectangular shaped. Check capacitance of both capacitors. You can also check the motherboard to see if there are any burned components.

[@christianfoster8400]

Thanks man! The capacitors test just fine. The fan motor is hard to find and a pain to get off so I’m going to go recycle the thing. I don’t know if it’s a European thing or not.

[@Nitrotix1]

Compressor works on mine, coils and fins are clean, fan speed is strong, but it is still not cooling the air it blows out. Does this mean the freon has leaked? I don't see any leakage.

[@ChavezDIY]

Interesting. Yes, assuming the compressor is working good, all signs point to low refrigerant. Run the unit with the cover off and spray soapy water on all the AC lines and see if you can find the bubbles, which would indicate a leak. You can also buy a refrigerant leak detector on amazon and see if that helps to identify any leaks.

[@Nitrotix1]

That's my next step before I decide to buy a new unit. I have hope that there's still a lot of gunk in the fins that can't simply be sucked or brushed out. This is for a less commonly used room so I can tinker with it, good way to learn how these things work as well.

There should be a capacitor that powers the fan. I would check the capacitance of your two large capacitors, the cylinder one and the rectangular one (located directly above the cylinder one in this video). My guess is that the cylinder one is for the compressor and the rectangular one is for the fan. You will need a capacitance meter to check them. The meter listed in the video description is cheapest one that I have found on amazon.

[@ChavezDIY]

For the 2 inch gap under the door, you can cover it with a door sweep, there are cheap ones at Home Depot. Portable ACs will not be able to cool down a room better than a window AC unit. I recommend portable AC only if you cannot install a window unit. If its blowing cool air, the only thing I can think of is to clean the coils, I have links in the video description to my video on cleaning the coils inside a portable AC. If you clean the inside but its still not cooling good, it just means you need a stronger unit. Something with more BTUs. A 8k BTU window unit will outperform a 8k BTU portable unit. My current window unit (6k BTU) in my office space is undersized so it takes a while to cool and never reaches a nice cool temp on a really hot day. I need to upgrade to a bigger unit with more BTUs.

I don't have any experience with that kind of problem. If you have your AC product manual it sometimes can give you troubleshooting tips. Try to find it online if you don't have it. Sometimes the red light can mean that you need to clean the removable screen filter. If it is not the filter light, maybe it's a power supply issue. Check the video description for a list of troubleshooting tips.

Had a similar issue - i changed the capacitor and the compressor is running but still not cooling. Any ideas?

[@ChavezDIY]

That's interesting, the compressor is actually running? Does the compressor feel warm when running? Start with making sure the coils (evap and condenser) and air filters are clean. Next look for refrigerant leaks, low refrigerant can lead to no cooling. Look at the coils for refrigerant leaks, spray a mix of soap and water on the coils at different locations with the compressor running and look for air bubbles that may indicate a leak.

[@ChavezDIY]

There's a list of things to check in the video description. My compressor was working, but not cooling. My capacitor was operating below efficiency, it wasn't completely dead yet. You need a capacitance meter to check the capacitor. Just because the compressor is making a noise and the capacitor is not swollen, that does not mean the capacitor is good.

[@crackerjackrappr]

What does it mean when the ac shakes violently?

[@ChavezDIY]

Good question. So it is cooling but shaking a lot? I'm not sure, but something to look at is the compressor and the fans. You'll have to open it and run it with the case off so you can see if there is a fan that is off balance or the compressor rubber isolators are gone. The compressor shakes quite a bit and has rubber pads that isolate the vibrations. When those rubber pads go bad from cracking/breaking then the vibrations from the compressor will be transferred to the whole unit.

[@ChavezDIY]

No quick fixes and it requires HVAC tools/skills. I have seen videos where people will cut the copper line and use a brazing method to attach a schrader valve. Then they vacuum the copper lines with a vacuum machine and then add refrigerant (type and amount specified on the AC). Here's a video of someone doing that kzbin.info/www/bejne/lZOvaJuEa7GGarM

[@buhrrito]

I paid $20 for a new capacitor but unfortunately that wasnt my problem.

[@ChavezDIY]

I'm sorry that didn't work for you. You need to use the capacitance meter to measure the capacitor before replacing it. It comes in handy. Capacitor failing is common problem and its likely you'll have air conditioning for the rest of your life so it pays for itself over time.

[@ChavezDIY]

Here is my checklist for troubleshooting AC: Clean the filter Clean the coils Replace capacitors Check for leaks with system running using soapy water Touch compressor, should be hot Listen for fans, should be running Touch copper lines, one should be cold the other hot Check motherboard for burned components Check wires for any loose connections Check connectors for corrosion, clean off any corrosion with wire brush. If none of these items help, its likely the compressor has failed. The compressor is the most expensive part so you might as well look into another unit.

I've had that happen with my car AC. I overcharged it and the compressor would turn on then turn off. It turns off due to overheating. The fix for my car AC was to slowly release some refrigerant until the compressor operated normally (stopped turning off).
