If you plug in the fan and nothing happens, the next thing is to check the circuit breaker. It is likely that the circuit breaker has been turned off. If the breaker has been turned off, just turn it on again.

Check power to the outlet –

If you have tried the two troubleshooting steps above and there is no luck, next is to check the power to the outlet. Try to plug in the fan to a different outlet.

Hello, Today I’m going to show you how to properly clean a box fan ah this fan has not had a lot of use but I thought I’d be Gatti to show everybody anyway just in case it was running how to properly clean any box fan it’s not very difficult and like to be very fairly easy so let’s get started first thing you want to do for safety is unplug the power cord so that we don’t get electrocuted or fandubs internal accidentally or something like that happens when we’re cleaning it then what you want to do is this may not apply to all fans but in my case my fan has a detachable cord set you’ll want to pull that out so that the fan will be easier to work with you don’t crush the strain relief on the cord now what you want to do is you want to let you fan down and now most fans will have these feet and what you want to do is you want to take a flathead screwdriver and you want to take your flat-head screwdriver and remove two slots like so right here to remove the feet so once again you just want to take your flat-head screwdriver and stick it in there and hold the air foot out like so and do the same with the other foot you can always just pull them out like I just did there and to cut the cord set the feet and everything removed next thing you want to do is let your fan flat on the floor and take a Philips head screwdriver and remove all the screws be sure to keep them in a little box so you don’t lose them if you take mile screws out you don’t want to remove the screen of the fan like so and uh after that you can flip the fan over and move the back guard the back should look very similar to the front once again remove our six screws and also you want to keep these screws once the other six screws so you don’t lose them as they’ll be very important when it comes time to reassemble our fan you’ll then want to remove the screen and set it to the side then you can put the fan over and we could move the family movable the fan blade is very easy first thing I want to do is leave a fan flat on the floor with the grunt removed and put one hand on the hub and one fan on and on the frame and just start to pull then after that what you want to do is sick one hand under and one hand under and gently Rock laid back and forth and apply pressure upwards so the family is moved just to the end of the shaft almost and just pops off sometimes on these near fans they are fastened very tightly onto the shaft so once you have all the parts removed you can set this frame to the side and you can start to clean all of your plastic parts so your plastic parts your family very real and your front grille they can just be wiped off you can take some paper towels here and just wipe it right off like so just make sure to get all the blades real nice make sure you get the hub the stabilizer ring and especially this plugin via la Dustin here because that’s where the cooling fins are for the motor you want to get all the dust out there make sure nothing’s in this little hole it’ll prevent you from sticking the fan back on to the motor shaft properly you can set the family to the side and sometimes these crabs this could be a little tricky so what you can do is take a shopback or a household vacuum and just back in these parts clean just take your shopback you know get all the crevices in there especially in this area by the motor your motor running cool you’re going to do the same with the front grille as well and doesn’t hurt use a little water on your paper towels we’re also waiting to do is you can take the fan grills set them in a bathtub and just let them soak there for maybe 20-30 minutes then after that we can move on to the motor it is very very important to keep the motor clean one thing you can do is take q-tip just get all that gunk out right there or if you want take a shot back vacuum out all the debris it is very important to keep your motor and clean so that your fan will have maximum performance right here this is your motor shaft and your bearing sometimes I’ll be a cooling fan sometimes are we not and sometimes the fan will have a cooling fan on the fan blade like this model does but this shaft and right here in the bearing needs to be oiled and you can use some lightweight oil zoom spout you can use three in one oil be sure to use the blue can not the black can the black can has a turreted it you’re not supposed to use detergent oil and fans only use non-decision oil some other things to note this is the power connection make sure this is all nice and snug this your start pastor some I’ll have a start pastors some are start everyone this is a start and run capacitor I believe I am not sure but I believe this start and run then up here up here is your switch sometimes this can be a point of failure if the switch is losing contact you can space on contact cleaner to switch and clean switch out or you can get a new switch if it’s totally failed there were side of the motor we have a very similar scene we have our motor this is a back bearing you want to grease this as well as lightweight oil or some other oil like I’ve mentioned in the previous section this is your power connection you want to keep this clean I suggest using a q-tip to clean this out or make sure there’s no dust in here this is your start capacitor or start run capacitor as well and you want to make sure this whole area is clean to keep your fan money at maximum performance once your fan is all clean you want to take all your parts and now it is time to reassemble your fan um depending on how your fan is assembled the factory wow you disassembled it there could be different parts and pieces and the parts would look different um but I’m just going to read some of this on my fan because that is how my fan is so you’re just going to take your rearguard like so and see mine has a slot that you stick the handle in so you just stick your handle in this slot right here on the tab pops in and now you also want to line up these screw holes right here so you can put the screws in and after you’ve done that you take your screws and put them in and once again this is plastic to metal so I would not tighten these very tightly just because we do not want to damage the plastic or strip the screws so just hand tight them don’t you know torque them down or use a power screwdriver they’re very long screws anyways so before you put your back guard on what you’re going to do is you’re going to take your fan blade and normally there is a little groove on the motor shaft so you’re going to line the shaft up I’m going to take the groove on the fan blade right here see my groove is right there so I’m going to take the groove and line up with this shaft just us family and it should go on there like that now once you put your fan blade on you want to put your rare guard on so line your very broad up make sure the logo and screw holes are lined up and take your Phillips head screwdriver insert these screws into the hole and screw them in just like last time you don’t want to tighten these very tightly because we don’t want to strip the screws just nice and easy once your family assembled want to take a two plus to stabilize your feet and push them into the slots until they click like so and like so depending if the aunt is if this is applicable to your fan take your detachable cord set and plug it into the back of the fan if your fan doesn’t have a touchable cord set you can skip this step the last and final thing to do is plug your fan in like so now that you finished all nice and clean just sit back

Video Transcript:

Hey guys, Joe tech here from Joe tech tips. Today we’re going to do something something we’ve done in the past however I want to do another newer video and we’re going to be doing how to fix a box fan I have a surrender surrender and rather external power supply here that does up to three amps at 0 to 20 volts and this is what I use on my bench for doing sand repairs such as this and I’m going to have an overhead here and I want to go this was kind of strange I was just about to do some work on the computer to substitute some more video editing and I heard this weird clicking sound like it sounds like where the heck is this coming from I’ll come a little closer to the computer I’m trying to listen and I thought maybe it was a wire hitting one of the fan blades and stuff like that it wasn’t and then I tapped the side of the case and also in here roarrrrr err like funky sound and I said okay let me take the side panel off and there was this monster coolermaster fans that started to make noise soon as I unplugged it the sound went away I was like ok I found the culprit so I want to revisit this again I had to repair a fan of a box fan this happened to be a very very large one so anyway to do this most there are two types of fans ball bearing and bushing I looked at this quickly it might really quite sure what this is I can almost guarantee is bushing most of the time ball bearing fans are on either I mean when you’re buying brand new with either the video card fan which is a real piece of crap most of the time is video caught fan and CPU fan all have ball bearing good quality stuffs will have bull bearing fans anything that’s like free in a case most likely will be bushing unless you’re spending ton of money like I so like son on they make some really nice fan so anyway we pull this off and this rubber piece is is blocking the the bushing or bearing so will be remove this so what I use I use a regular paper clip to to apply lubrication in the fan now I do this not because it’s easier it’s real simple to use I use motor oil by the way for lubrication I find that to be the best for lubrication wd-40 is a temporary fix it will evaporate oil does not evaporate it’ll stay there it will eventually wear away but it doesn’t evaporate so what I did was I pulled this off I don’t want to pull it off completely because I want it to still to be still stuck on but I want it out of the way so you can see so I have a little cup here with motor oil in it and I just drop it in soap like so until it actually absorbs so what I also do though is that I have I have the fan running so what I do is we’re actually going to connect this I have all types of connectives on on this power supply I’m gonna power up I have it set for 6 volts right now just low I don’t want to be blowing oil around so it’s actually 5.9 drop it down a little lower then we’ll start drop it in the oil you got to careful that you don’t get it on the area with it it’s going to be stuck too we’ll keep doing this until it looks like it’s pretty much full and then we’ll crank it up to full speed and the noise should go away well this is the easiest way to apply oil to into inside of the inside of the fan section where you need to be looks pretty good actually I’m going to keep going I want to put as much as in here because this is this goes on the side of my case on the door and I’m starting to work pretty good and this should last pretty much forever should never shouldn’t have a problem because we’re lubricating it with motor oil let me crank it back up to 12 volts and it should be nice and quiet and you shouldn’t hear it at all you rip rip blowing away right now at the DMR radio on the background so let’s continue popping this on here it looks like it’s lubricating it going in through and through the sounds good actually I don’t hear that noise anymore I don’t even hit a fan there we go I was taking a lot of oil the big fan usually one or two drops of this with a regular sight you know like a 90 millimeter 120 millimeter fan so all it takes looks great I will hear it at all so what we do after that I want to power it down I’m going to put the plug back on and it cover it back up again we’re pretty much done that’s it put this plastic thing back on the seal and then we’ll seal it back up again because we didn’t lose the sticky which is nice and that is it that is how you repair a box fan and nothing to it really but there’s no monoid mics and quiet now you can hear it on the microphone I was making a lot of noise this was annoyed racket a lot of racket and I could crank it up a little higher we’ll go to 14 volts just to work it through but that’s it that’s how you repair a box fan real simple if you liked this video thumbs up if you look through my videos you’ll see a video card repair fan and a box fan and I’ll show you how it’s done I’m this one it wasn’t as bad as the other ones on 6 in the past but I wanted to bring it up again we a revisit of how to repair a box man this is Jojo Tech from Joe tech tips if you like this video thumbs up and we’ll see you next time take care.
