...do you know what a resistor is?

it's probably that fat TO247 package BJT thats fried

>>1073104
i just posted 3 pictures of my resistor

This connection looks kinda iffy. Looks a bit cracked from the board on this side and there's very little solder spill over to the other side - might just need to be re-done.

>>1073096
May be a cracked solder joint

>>1073105
So to answer
>>1073104 's question, no, OP does not know what a resistor is

>This connection looks kinda iffy. Looks a bit cracked from the board on this side and there's very little solder spill over to the other side - might just need to be re-done.

actually it does look iffy. there's two dark lines on the photo which suggest a crack, but i couldnt say for sure without seeing it in person. if you press on the resistor (i.e. transistor), does the middle leg move in and out?

I concur with the other anon about the solder joint, looks like the three legs are cold joints because there isn't enough solder on the up side

10/10 meme post right here

>>1073279
it does not. no visible cracks on it.

took a brush to it and cleaned up the board, plugged it back in and it works again

thank you!

I still cant tell if he's trolling the shit out of me.

Way out of my league if he is tho, top tier for sure.

>>1073418
I'm not sure if you're trolling or not, but you are incorrect.

From those images, that joint looks fine. It's a through-plated board, so the fact that solder hasn't fully flown to both sides is not an issue. The "crack" you point out is flux residue from hand soldering. If that joint is cracked, you need to clean the flux off first in order to find out.

>looks fine
no

>solder hasn't flown is not an issue
wrong

>crack is flux
wrong

>need to clean to find out
nope

your observation standard is literally ghetto-tier hobbyist, shit solder joints like these are called cold joint and they crack exactly like ops example

>>1073254
in OP's defense, these are formally referred to as blower motor resistors in parts catalogs.
>in the USA, anyway.

Well that isn't gonna make people confused... You damn burgers!

I had this happen on my Chevy. Dealer wanted like $180 for the part. I just fixed it. Fuck dealerships

Nigger I fix shit like this for a living and I used to make this mistake a decade ago. That is flux residue. That component was hand soldered. You need to clean it off to see if the joint is fine. It most likely is. Solder flowing through on a plated-through board doesn't matter unless you're dealing with motherboard VRM tier currents.

Furthermore, solder joint cracking on plated-through boards generally happens right around the leg of the component, not around the base of the joint. Since the solder is adhering through the via in the board, the base of the joint is very strong.

TL;DR stop making hasty diagnoses over the internet. You cannot tell the state of that solder joint from that picture.

you're a contradictory little fag.

Thing is, they used to literally be a few different high wattage resistors that the switch would select for different fan speeds.

>>1074854
Come at me brah, I'm just giving you a guess based on experience.

>>1074726
able to do visual checks is a basic skill of a technician, you working in the corner shop repairing mobile phones for over a decade doesn't count

If the solder joint was truly bad, the motor wouldn't start to spin. It wouldn't spin at all.

>>1074938
You are right. However, in order to do visual checks, you need to make sure you do not have something obstructing your view.

Are you contesting that there's a giant blob of flux residue right where the supposed crack is?
