Unable to determine if it was the heat stressed plastic to blame, or the shop air compressor... I wasn't the one manning the compressor at the time.

Re: She dun blowed up!
I have never used a compressor to clean electronics out. Of course the Navy instilled that in me. Working on aircraft, they made you vaccumn it as blowing it just moves it somewhere else (where you can't see it). I know a computer isn't a matter of life if something gets blowedd under the board and shorts out, but I have always vaccumned the computers and all other electronics I work on. Amazing how much and often smokers need their stuff cleaned. The tar is sticky and the dust sticks to it. I use a regular house vaccumn with attachments that have little brushes and extension to get into small places. Then I wipe the fan blades off with cuetips and denatured alcohol. -
Re: She dun blowed up!
This is the first time I've ever seen one of these come apart like this, and I don't even know that it was related to using the compressor. I'll continue to blow my PCs out with 60 PSI.Ludicrous gibs!

Re: She dun blowed up!
I have never seen one blow apart with an air compressor and I do this everyday for a living... The only thing I could think of is if the plastic was very very old and brittle Fun to look at though

Re: She dun blowed up!
At first I thought maybe the plastic was old and brittle, and then a cockroach found its way into the fan, and everything shattered, but I found no solid non-fan material anywhere in the PSU. It shall remain a mystery.Ludicrous gibs!

Re: She dun blowed up!
Compressed air works a lot better than vacuum. I'd only use a vacuum if the "outside" was unavailable to redistribute the dust in.
New computer service people blow fans up all the time.Comment

Re: She dun blowed up!
Ouch. The only time I've seen that happen was to a normal fan (not a hamster wheel one) when I was testing it out near a window and it sucked up the curtains.I love putting bad caps and flat batteries in fire and watching them explode!!
No wonder it doesn't work! You installed the jumper wires backwards

Re: She dun blowed up!
I was cleaning about 30 or so computers with these fans about 3 weeks ago. Used 50-80 PSI and none blew up like that. Interesting...
Does the motor still run?Comment

Re: She dun blowed up!
my guess would be it got brittle and busted one blade, which took out another, which snowballed into total fan failure.sigpic

Hello everyone, my old but loved LG GR-642 stopped cooling and frosting all together.
The display shows everything as normal, the focused cooling activated when I open the doors but the compressor wont start.
First I measured the terminals on the compressor at the back of the fridge. 0 volts.
Now I disconnected the compressor and measured resistance on its leads: around 8 ohms.
I dissassembled the main powerboard, couldn't find anything suspicious but I noticed that the comps relay wont send voltage to the pin, while Fan H and fan L is indeed at 230V.... -
Hello,
our fridge and freezer stopped cooling last weekend, it’s a Beko fridge.
looking at the bottom, I can hear the relay clicking on the plug attached to the compressor.
There is also a 3uf capacitor, I’m thinking this is a run capacitor, I tested this with my fluke and and it measured at 1.5uf, so I replaced this (new one tested just over 3uf) so that’s where it should be.
I was thinking this was the issue. The compressor seem to run for like a minute then shutoff again.
inside the relay, there is a Klixon 4tm thermistor,... -
This is my son’s cooler for his semi truck for his drinks the other day it started short cycling ( running for a second or two then shutting down ) and restarting four or five times then going into an error power cycle the controller then it would do the same thing again
Found a 47uf@63 volts double the ESR value of a new one
The 220uf@16 volts same as a new but 220uf@35 volt replacement capacitor
The main filtering capacitor was not replaced because I did not have that was not too tall
Where the 220uf capacitor is some type of switching power...08-30-2022, 05:28 PM -
I found this YouTube video on how to test a inverter type compressor
It also shows how to make a testing device to test the inverter type compressor

Hi all,
I have this air compressor by Einhell, history unknown. It has two modes - 18V battery and 240V AC. On battery everything works fine. On AC it switches on, but makes a quiet repetitive buzzing noise, and the second you start either of the air pumps it completely dies most of the time. On occasion it will work without fault.
Only thing remarkable on physical inspection is that the filter cap on the PSU board has a scorched positive lead. It is 150uF, 400V, 105*C. The cap is an awful Asia'X brand. Is it possible this filter cap is the source of the fault, or is...
