Curses it’s also the blower motor for me. But at least I know what the problem is now! And thanks for the link! It’s the same model for me.

Just bought one of these a few months ago. It's good to see know that it's easy to source a replacement blower fan.

That bottom left tab makes it impossible to close. I am gonna have to break mine too

Ahhhh man, THANK YOU. Whirring noise is finally gone. I really appreciate the time you took to make the video and the tons of research that you have saved everyone that watched this video. You should leave a link to your venmo or something for those like me who would like to buy you a coffee or beer for the effort and knowledge share.

seeing lots of people complain about these things after only a few years... and those plastic clips man.. those wont last 4 servicings before they are all busted up and the things rattling.... great build quality

6:06 i know DIY repair voids warranty. Does just opening that void warranty?

0:45 Thanks for the warn, i will not drill. instead i'll make sure it dips more to the outside.

Thanks for the video. I broke my blower fan by putting a thermometer to far into the opening. I was able to buy a new one for 19.99 and with this video had it up and running within an hour. One tip I have is that I did not have to remove the entire plastic housing around the fan blade. I took all the screws out and was able to open in enough from the top to remove old fan and install replacement. This saved a lot of trouble of having to get the bottom of the housing lined up and probably knocked 15 minutes off the job.

Great DIY video, with 19k views it seems you helped a lot of people with what is most likely a common failure on those units. Congrats! A tip I would like to share with everyone regarding the lubrication of parts encased in plastic - Only use pure silicone grease when lubricating plastic parts, or plastic parts with metal shafts. Pure silicone grease is completely inert to the majority of plastics and rubber, that is it will not erode or harden them. Petroleum based grease will cause damage to plastic over time, and the damage will be irreparable. Lithium and white lithium grease is petroleum based as well. You can find pure silicone grease in many places. The plumbing aisle of any hardware store will have food grade silicone grease for faucet O-ring grease. A 1/2 ounce tube will cost maybe 5 dollars and last a long time for homeowner use. Use it grease plastic gears, that shaft of the fan where it enters the plastic bushing, and you can even put a small amount on every electrical connector in that AC unit to make sure water dirt and moisture will never contaminate those connections, making them easier to remove in the future. You can use food grade silicone grease on hose connections for garden hoses, washers and what not ensuring they will come apart easily years from now. Also, while you have everything open, a good quality can of coil cleaner can be bought for less than 10 dollars. While working on an AC unit take the time to hit the inside and outside coils with coil cleaner and a light rinse, the coil cleaner will remove fine dirt that starts to reduce the unit efficiency, and has corrosion inhibitors that will prevent/treat all the different metals and solder of a coil assembly against oxidation.

Funny, Amazon has subscription option on this motor. Recommended every month.

For tight spaces, they make screwdrivers that are under 3 inches long at any hardware store. Phillips head/driver tips come in at least three weird hole sizes. For those tight spaces, if you use a magnetic driver, and the screw is aluminum or plastic, take a tiny piece of tape, wrap it around the screw and the driver, so it holds the driver tighter than the screw. When you screw it in, the tape will stick to the driver. I discovered that idea while working in tight, deep computer spaces. That damn noise! It sounds like Cicadas! ~~ THANK YOU!! ❤

Thank you so much for your video! After much research I bought one of these used, and after hearing the noise when turned on I know why they sold it(supposedly moving to central air apt). Your video was fantastic, and such a huge help while I replaced the motor yesterday. You saved me a lot of worry and money as I am a do it myself person. Also a thumbs up for videoing this at the same time as the repair. Very talented. 😊

yo man @nickrobinsonisthedev thanks for this video so much im about to tear mine down. luckily i have no motor issues. not so lucky i didnt tip the unit back far enough now the blue blower is BLACK with mold... couldnt figure out how to get inside to the blower fan. at 34:50 i saw what seemed like a few mold spots left that although are now probably dead from the cleaners, will give some meat for new gross stuff to cling to. im going to try and avoid the electronics whilst submerging my fan blades in a bucket with a bleach solution and go the nuclear option on those little suckers. ill let you know if it goes catastrophically wrong :) p.s. you know of any SAFE... emphasis on SAFEEEEEE mold inhibitors to treat these surfaces with? thats gonna be my next rabbit hole to dive down before i inevitably have to clean it again next year. <3 u buddy be well.

Thank you so much! Just finished the motor replacement and I'm so relieved to have my quiet a/c back!

does this ac pull outside air inside? or does it recirculate inside air?

I just did a cleanup with the Midea Duo portable AC (I haven't done it yet on my U shape yet... but will soon). It's more involving on that unit compared to the u-shape model when i look at the vids online. It took about 5 hours I'd say, maybe longer. Just my opinion for anyone reading this but if you're going to go through all the hassle of tearing this down I think you really should go blade by blade on the squirrel cage cleanup. I ran mine for just 2 summers and it was really gross. There's no way, NO WAY, that simple water with no pressure is going to clean that up. It's really embedded on the blades. The undersides as well will likely be filthy. Compressed air does nothing as well. It really needs agitation and something physical hitting it and brushing it off.

Good job but wash the front plastic cover lol😊

hello Nick - so helpful - quick question; i have dust caked on the coils (front unit) what is the best way to clean it?

HUGE thank you for this breakdown. I didn’t have a motor issue but I did need to do a really deep clean. When I finally got to the fan, it was covered in mold 🤢 But your vid helped so much, especially your tips on the tabs and wires. Really appreciate it!

WAY TOO HARD TO TEAR DOWN, AND EVERYONE WILL NEED TO B/C IT COLLECTS SO MUCH GRIME ON THE BLOWER WHEEL AND STARTS SMELLING LIKE MOLD/MILDEW AND IT IS NASTY. WOULDN'T RECOMMEND THIS UNIT FOR THAT REASON.

I just finished the motor replacement and this video was very helpful. Especially with the link to the correct motor on Amazon and the hidden screw that comes in from the back side of the blower housing. I'd would have never found that screw without your help. The fan shaft setscrew was a bear but my drill-driver got it out with the light impact.

You saved me! thank you so much for this, I have my AC back in perfect working order again!

Awesome job on the video man! After 3 years mine is making the exact same noise. Now I know where to get the motor. I did clean the blower last year by taking off the front flap and reaching inside, but you can't reach all of it. It was pretty coated with crap because I live in a dusty area. I think this is what causes the motor to start whistling due to the blower getting out of balance. In the app you can manually set the fan speed and I found that around 40% helps it to be less noisy. Also a ratcheting screw driver will help get to the tight places like in the back. A putty knife and some plastic wedges will help with the separation at the tabs. Cheers!

You can straighten the bent aluminum fins by using a fin comb. They are available online. The combs are color coded to match the number of fins per inch, so be sure the comb you use matches the fins on your unit.

The rubber piece on the end of the squirrel cage fan is not a stopper, it is a bearing that supports the fan shaft. When the lubricant in the bearing is depleted, it will start to make noise and the shaft may stop spinning. You can add oil to some bearings or just install a new one.

I helped my girlfriend install her Midea-U today, but a minute after the unit was turned on, error code 07 appeared on the display. Midea does not list error messages online or in the instruction manual, but Amazon explains the problem that many people have had. A piece of black vibration dampening material is wrapped around the 2 copper pipes next to the condenser coil fan (the section of the unit outside the window). If the material extends too far, it will prevent the condenser coil fan blade from turning, causing an error code 07 . In order to make the unit functional and prevent the error code 07, remove the top cover from the outside portion of the unit (3 screws on top, 2 screws on each side and 3 screws in the front. To remove the 3 front screws, a stubby screwdriver is necessary). On the left side, by the compressor are 2 copper pipes with the black material between the pipes. Trim or push the black material away from the fan blade so it spins freely, then install the cover and screws. It is easiest to test the unit before installing it in the window to be sure it functions properly so you can make the repair if needed. The fan on the inside part of the unit did not have a problem and worked normally.

Tip, you don't need to remove the screw from inside the blue blower fan, just loosen it a bit

I haven't even bought the unit yet but thank you for this. Good to know that it's repairable by a layman like myself.

I used your video to clean my unit and the instructions are very clear. Thank you.

Mine doesn't want to turn on.

Thank you! great video!

For cleaning the blowers, there's an easier way without removing the blades. Just get yourself a large nylon straw cleaner and some pressurized water bottle. Remove the blower louvers (large one is attached at the sides and small ones pop right off), then use a flat head to remove the metal grate (note remove the bottom attachments first and then slide up. The top middle grate is really hard to remove). Once you have access to the fan blades, spritz with soapy water (maybe some Oxygen bleach) and then mechanically remove mold with the straw cleaners. Once done, rinse off with more water and let air dry with the front open. Be sure to catch the water that comes out the from the bottom.

Very well done. Thankyou for taking the time to make this video!

I have phorid flies living and breeding in my unit, and I'm about to LOSE MY MIND. I've had the front of it wrapped in a trash bag for a week hoping to break the life cycle, but we're hitting mid-90s these days, and it's rough in this room. Starting to think the only solution will be to try to disassemble and sanitize what I can, but I don't think I can do all of this. 🥲 Thank you for showing me how if I attempt to try, though.

nice work man!

Is this the same motor for the 8k - 12k model?

You might want to invest in auto trim tools

I'm thankful that I purchased by mistake the standard Midea air conditioner now.

You are a legend, this video is more helpful than anything Midea shared with me. I was quoted $300 for someone to clean it and able to do it on my own thanks to you! Really appreciate that you took time to share all of that with us.

My downstairs one i got 3 years ago does this, I have 2 more upstairs that are perfectly quiet. It is also one thats been ran more then the rest though...

U Used The 13W or 20W Motor ??? Got The 12K BTU Version Of This AC, So Far So Good. Thanks For The Awesome Video.

Thank you for the video very helpful. A few things to point I didnt have to rip the side protector nor break the top tabs. Pro tip use some toothpics to stick on all the tabs after pushing them, starting with the top ones. Then you just pull the whole backpannel off in one go.

Thank you very much. Watching from the Philippines. I got the same problem with the blower noise.

Not crazy about that unit, both my neighbor and I bought a 12k unit. I don't think it blows enough air for the btu rating. Mine started to make a whining noise more detectable at low speed. I was luckier than you, they asked me to send a sound file and the engineers who listened said it was abnormal and they let me get a refund. I had wanted to keep it and I contacted them saying is there anything I can do to fix this thing? I had it in so securly. I have to say, I have installed many many ACs and this was by far the harderst. What a pain. First they told me to take it back to Home Depot, HD said what? Even though I had authorization from Midea. So Midea refunded and I am donating the unit. Replacing it with an LG dual inverter which is not a U shape. The U shape supposedly lets you use the window but no one is going to use that feature, you have to put insulation around it to keep critters and drafts out.

Fire extinguisher... lol. What confidence.

Excellent video. Have you attempted to disassemble the outside chunk? I believe that is the condenser, it's gotta get filthy with all the pollen and dirt we have. How often do you clean the squirrel cage fan?

Did you ever find a reset button? I’d like to try to factory reset the unit back to factory settings. I find it’s not working as good as it did when I first bought it. All the coils and fins are clean. I keep a wattage meter on the plug to see how many watts it uses. When it was new it would go up to about 1,200 watts but now it stays around 320 watts and sometimes 430 ish watts. If I could trick it and make it run full blast it would be awesome. But being it’s a smart Energy efficient unit it kinda sucks. I can keep it at 60 on cool on fan on high and still 320 watts. No Eco on and boost on.

This looks easy compared to replacing the condenser motor. Have to take the front off to get to the plug for the motor.

So your inside fan motor wasn’t working My outside fan motor isn’t working Are both a direct replacement Thank you

That was an excellent video breakdown brother. Exactly what I needed to tackle this to clean the fan blade. Thank You.
