Today I was grinding some espresso on my old ditting grinder for a friend. All of the sudden a smell of ammonia comming out of the grinder with a faded smoke.
But the ammonia smell was there for sure.
Came back later and ground some coarse coffee. Stop the grinder in the middle, but it wouldn't start after that. I took the blades apart cleaned them up, and started working again...any ideas?
Bruches, bearings ?? Old grinder 199?
Thanks,

Only thing I can come up with is bacteria interacting with urea & uric acid. Keep the chickens out of the coffee processing shed! ;D

Yeah, but we'll drink stuff that's been crapped out of a civet . . .

Compared with that, ammonia ain't much to fret about.
LOL
edit: BTW, look at that critter's eyes. They're the color of ripe coffee cherries. I wonder if the stuff has an effect on 'im like the geriatric spice melange had on Fremen on Arrakis, with the blue-in-blue eyes and all. ;D
edit again: DUDE! (http://www.bestcigarprices.com/cigar-directory/oliveros/oliveros-kopi-luwak-luwak-cigar/300-11171.htm)
I've seen it all. :P

Ammonia smell might be coming from overheating on the windings of the motor, loose brushes or connections... Dirt could be causing excessive arcing as well and burning the crap in there giving the smell, and on / off again .
If you seen smoke though, that's not a good thing, .... it might just be a switch getting ready to give up the ghost, and not the motor.
or could be years of gunk / grease too... it's hard to really say w/o opening it up and taking a peek.

The ozone smell of overheated wiring isn't close to an ammonia smell. I do agree that it should be checked if the problem is recurring. Find a qualified technician and be prepared to pay his kids college tuition. ;)

You were 100% correct, the smell came from grounds going inside the walls of the capacitor. I would have to assume that the plastic burning together with the coffee grounds caused the smell. Lots og blck tar, I cleaned it as much as I could. The capacitor smells like and old (very old tv)...
Should I replace the capacitor with the factory one ($54) or get one locally?
Thanks,

$54 FOR A CAPACITOR?!

$54 FOR A CAPACITOR?!
Just bought a new one at my electronics supply store for $7.95, and thought that was a bit rich. If you do buy the $54 one, make sure to get kissed! >:D

When I need a large capacitor, I go here: https://www.surpluscenter.com/sort.asp?numrec=20&sort=2&keyword=EMRC&catname=electric&UID=2009100610380448 (https://www.surpluscenter.com/sort.asp?numrec=20&sort=2&keyword=EMRC&catname=electric&UID=2009100610380448)
I don't think any of them are more than $15, and most are under $5.

OK, BW! Now how about a quick primer on how to select the correct capacitor for one's application?
-
Same capacitance, same or higher voltage rating shouldn't give you any trouble in a motor start application.
-
Put the smoke back in and your good ta go!
Smoked a very large isolation transformer on an extruder last night at work (power interface board/field control problem-500amp!) Fired it back up after removing panels and cooling it down - don't know if it kept on cooking after that >:(
-
Stay within the replaced capacitors tolerance ratings. 10%

Not to big not to small! ;D

I would say that if a guy doesn't know enough about capacitance and electrical operations to select the correct one, they probably shouldn't be messing with it in the first place!
I do know that Monito is quite sharp in that department, based on his posts over the last 3 or 4 years out here.

An aside: Back in my wild days, when I used to tie-dye for a living, I would use large microwave ovens to accelerate the fiber-reactive dye bonding process with cotton by quickly heating it for a few minutes. I put microwave ovens through hell, and many of them gave up the ghost due to short-circuits and corrosion from the amount of steam building up and condensing in them. I nearly got electrocuted by capacitors on two instances while trying to fix these ovens. Old-school microwave ovens have big capacitors that can store a substantial charge... It's a good idea to discharge them before working on them. It's an even better idea to have someone that knows what they're doing perform the repairs. I was rather foolish and didn't want to cut into my beer money, so I learned about these things the hard way.

I actually took the thing apart to clean the tar, of course I discharged it first...its working with no smells. But...
I'll go to http://skycraftsurplus.com/ here in town is an old junk electronics kind of place.
Thanks for the advice,

Hey!! Thanks for that link - that is my kind of place - bookmarked in with my other surplus goodies now.

You can probably goto any appliance repair center too, ie washing machines, ac/s etc and try to get them to sell you a cap too. It's probably a start cap, and a bigger one gives a bit extra kick but wont hurt too much. A run cap now might cause issues. I know they'd do that with old AC compressors as they get stubborn, throw an extra start cap in paralell on the thing. Id get a call for my ac is not working and open the thing up and there's like 5 of these 'hot shots' on the compressor leg and it's like. ok hey dude, your compressor is shot ok... you need a NEW one, NO I will NOT put yet another kicker on it and be held responsible should the thing decide to go nuclear.
Heck you can scavenge one out of an old appliance maybe.
