What's this electronic part?
My coffee grinder 'ground' to a grinding halt 
, so I took it apart and
found this zener diode-FET transistorless-capicitated resistor-seven fetzer valve-IC-fuse
looking thing soldered between the motor and the hot side of the power cord.
It's about 1/2" long and about an 1/8" diameter.
The grinder does work when I 'bypass' this component.
Does anyone know what it is, and do I need it?
Thanks

Some kind of overload protection device?
That makes sense to me in that if it were important to the operation of the unit, the unit would not work without it. If the company didn't need to put it in they wouldn't even if it cost a penny since a penny saved on 300,000 units is still 3000 bucks the company would save. (check my math on that one!)
So, they must be required to put it in to comply with some kind of safety code.
Leave it out, if you're not afraid to burn down the house. But if you stand there and watch the coffee being ground then unplug the unit when you are done, what's the harm?

It looks like a thermal switch. It's worth about 3 bucks at an electronics distributor. It regulates temperature. There should be a temperature rating on the side of it and a part number. In short it's a switch that opens a set temperature. Lots of times they just fail because they go bad. Other times it's like an overload protection. Maybe the motor in your grinder is seizing.

A thermal fuse blows when other components are bad, thus causing too much heat. If he only replaces the fuse, it will blow again because he didn't fix the reason it blew!! So he can either replace all the components, figure out which one is bad and replace only that component or pop for the $10 bucks and buy a new grinder!!! I'd buy a new grinder,,, They are way cheaper than a new house!!

I should have proof read my post.
I forgot to add "it's my friend's coffee grinder....."
She apparently grinds coffee to a real fine grind.
I'll tell her to buy a new one, and I 'MIGHT' spend the $1.69 for another thermal fuse and solder it in.
If it blows again, no biggie. I'll just destroy it and toss it in the garbage.
I'm not too worried about a coffee grinder.
I'll store it next to the gasoline and TNT I have over the stove.
And thanks for the replys.
I need to replace my 1200 sq. ft. home, I mean 3600 sq.ft., I mean 5000 sq.ft. home.
