Delonghi portable upright air conditioner: Need advice on how to disassemble Delonghi PAC EM82K.1 portable airco

Mon, 17 Aug 2026 12:59:40 -0700

Dear community of IFixIt

Today I attempted to deep clean my Delonghi Pac Em82K.1

I removed every possible screw I could find, but nothing from the outer casing would move at all except for the top display panel (and only slightly). I looked everywhere online, but could not find a guide neither by Delonghi or by other people on how to disassemble it.

Therefore I wonder if anyone here could help me figure out how to disassemble this unit so I can properly clean it, to make sure it functions as long as possible.

I have a suspicion that it is being held in place by very annoying and stubborn plastic clips. I tried prying open the top but to no avail.

I sent an e-mail to their customer support team and they told me opening/disassembling the device will void my warranty and that due to safety reasons they will not provide me with instructions on how to disassemble it. Seems like another one of those anti-right to repair companies.

Air Conditioning: Won't turn on

Wed, 12 Aug 2026 12:29:42 -0700

I have an older Danby, which I keep unplugged when not in use. When I plug it in, it beeps and the display shows for a second, then disappears. The power button doesn't turn it on. Unplugging and replugging gives the same result, a beep and a quick display of the last temp I had it set on, then it goes off again. Power button won't turn it back on. I've already tried the test and reset buttons on the power cord, which appear to be functioning properly.

My AC isn't cooling properly; even though the temperature is set to 16°C and Turbo mode is activated, the cooling output doesn't match the set temperature.

My dehumidifier has not been collecting water in the drawer. I have just taken the filter off to have a look and noticed water in the back. Is there anything I can do about this? I can’t find any blockages to the water to drawer.

Dyson AM07 Tower Fan: faulty fan now board dead

Thu, 02 Jul 2026 03:51:16 -0700

So i have just replaced the oscillating motor and the x2 cap to fix the side to side movement and stop it happening when it's off! the main fan motor was a bit noisy, so i decided to take the impeller off the motor and clean and lube the bearings...bad idea! the impeller ended up breaking the locating lugs off the bottom of it, and after all the messing around, when i turned it all back on, the motor was really unhappy, causing surges and then cutting out completely. tested the fan from a known good machine and it worked for half an hour continuously at 10 without any issue...

I managed to source a second hand unit from a dyson repair shop nearby, and it arrived today - plugged it in, the display came on, motor did nothing...seconds later the screen went dark and nothing worked since. i've since tested the motor, and it seems to have a short/very low resistance between the case and W1 phase wire - obviously it's sent 300v upstream and done some damage!

I've checked the fuse, all the 0ohm resistors i can find, and run through a load of testing with the help of AI to prove the buck regulator, the mosfets and the driver ICs all seem to be behaving as expected. however, after tracing U2 (5v regulator), it seems to have a direct short to ground on 2 pins. from what i can find, it appears pin 1 is output (apart from anywhere else, it supplied voltage to the screen), pin 2 gnd and ping 3 input - which appears to have a direct connection to the buck regulator IC output. thinking the 5v regulator had gone short, i pulled it.....and still have the short. then i removed cap c7 to make sure that wasn't shorting....it wasn't either.

Literally tearing my hair out now (shop said they wouldn't replace the damaged board, but have agreed a 50/50 split on a new board if i have to; but I would rather fix this.

Can anyone offer any advice? any common failures when the motors go short?

Thanks all!
