I have a midea 5k, it was short cycling due to low volatage on the oil rig, I got a 10 gauge extension cord hooked to a reastate voltage regulator to give me 115-125v at all times. It worked great until recently. i cleaned everything out but still it shuts off in the heat of the day when i need it most, all voltages are fine. I think its time for a new one, proabably gonna get an LG model after seeing this video, that ac you had apart looks much better built on the inside.

[@Caliber8Tools]

Interesting work around with the larger gauge cord.

Thank you a very detailed but simple explanation!! 👍

You’re welcome. Glad it helped.

Hey ! I have the exact same AC. However, my problem is, the A/C start cooling for about 30 second, and then get back to Fan mode, and after 10 min, restart this loop again. The room has 0 chance to get colder with this, i only get cold air if i stand infront of it during the cooling phase. Do you have any fix for that? My model is LP0910WNRY2. i think some others model have a manual mode. Mine seems to only run on auto/eco mode

[@Caliber8Tools]

It’s short cycling. Usually happens when the filters are dirty filters which will restrict airflow causing overheated coils or frozen coils. Try cleaning them. Keep the vents unobstructed by walls. Also could be low on refrigerant. Don’t forget to see if your thermostat is at the right setting for your room size.

Hello! I have this exact portable AC unit. I am just now running into problems with it after recently cleaning the AC filter a couple days ago. I keep getting the “FL” signal and the bottom drain pan if full a causes the float switch to move up and shuts off the unit. Why is it all of a sudden I am getting so much moisture that I have to drain the unit every four hours? It’s driving me crazy. Any comments you have would be helpful! I also want to note that the humidity levels in the room are higher than normal (we are in the rainy season of Florida) but it’s never affected it before until I recently cleaned the filter.

[@Caliber8Tools]

Dirty filters can cause evaporator coils to freeze up and thaw out leading to excessive water in the pan but you cleaned them. So it’s probably due to the high humidity, which is the cause of the FL signal coming on. More water is being condensed than it is being evaporated. Until the humidity lowers you may have to keep your draining schedule. A clogged drain line can also contribute to a frequently full drain pan.

I'm having the same issue! BRAND NEW UNIT now, nothing is dirty. Every 2 hours it waffles me up to drain. I have FOUR units on my house, and the only one that keeps doing it is the one in my bedroom. HELP!

[@bookiemonster2000]

I just bought a brand new unit in Portugal and it's short cycling :( My offgrid space gets up to 38C/100F and yet my unit refuses to behave. It draws about 2,500W and my inverter can deliver 3,000W no problem. It's 14,000 BTU and my space is 40m2 about 430ft2. I have a feeling it's my space gets entirely too hot (severe greenhouse effect) and the unit just can't handle it... I dunno what to do.

[@Sarnarath]

If you can shade any windows from the outside that would be a big help already since there is less energy coming in through the windows, maybe plant some trees next to the cabin and get roller shutters.

[@Caliber8Tools]

Are your vents obstructed? Up against a wall? That could restrict airflow and cause short cycling. All other reasons would not apply to a brand new unit. 14,000 BTU’s should be enough for that size room.

[@LifeOfAmlet]

My filters were dirty. I’m wondering if the dirty filter messed up something else. Like ruined the compressor? How do I know?

[@Caliber8Tools]

Dirty filters can cause the compressor to work harder and even cause it to shut down.

[@LifeOfAmlet]

@@Caliber8Tools can you replace a broken compressor?

[@Caliber8Tools]

Yes, they can be replaced.

I have a question, my ac unit , exact model as the one in the video , it’s plugged in but not turning on, the led screen doesn’t turn on and it won’t start, but the plug to go into the wall works, what could be wrong with it, before it stopped working the screen would glitch and it would be stuck on a number , I empty it each morning as I only use it for the night time. I wanna save money by saving my Ac please help if you can

[@Caliber8Tools]

Sounds like an electrical issue. Could be a fuse or circuit board issue. Is your cord in good condition? It can also be a bad capacitor. In any case take it or a professional to check it out. Let us know what it was. Thanks.

[@ehelstein]

@@Caliber8Tools I'm having the same problem, the unit is clean and well maintained. I pulled the 15 amp fuse from the board and checked it, visually it appears to be functional... is there more than one? Thanks in advance.

[@doomtucan5093]

my problem is not filters at all. filters and coils all cleaned yet still only blows mildly cool air.

[@Caliber8Tools]

Could be a thermostat issue.

[@doomtucan5093]

@@Caliber8Tools that gon cost an arm and a leg to replace haha

[@makodaniel4885]

freon maybe

[@makodaniel4885]

Try to see if your remote has a feature where you can set the system to cool based on the remotes temp instead of the temp inside the unit. this will rule out thermostat

[@doomtucan5093]

@@makodaniel4885 nope just has cool,fan,dehumid modes and low and high fan setting.
