Helpful Posts: The classic American fan heater is a crude affair but quite long-lived. But now they are all made in a far-off land and, while prettier, are quite poorly made (surprise).
Now they look like this:
How d'ya like that Spanglish? I think "no cober el calentador" might be a bit closer.
One day it stopped heating. So I took the thermostat out which, on this kind of heater, usually just needs the contacts cleaned . . . . not this one though:
What looks like a screw thread should actually be dome-shaped and riveted to the metal blade.
Nice discoloration colors indicate that over 10 amps passing through a dirty contact can generate quite a bit of heat and high temperatures.
The spattering visible at lower right on the next blade down tells of the destructive arcing that took place.
Panasonic DMC-GH1 m4/3 with the Leica 45mm f/2.8 macro set to f/22 IIRC for this last shot. Lit by two LED floods. Processed with RawTherapee.
The other two shots were processed with FastStone Viewer.

Oh well Ted, at least the part number is still visible so you can get searching for a spare

What a great idea I usually just go to the recycling with our duff stuff, maybe I should investigate and capture the faulty/worn out items. Well done Ted.

Looks like they may have invented a new form of hight current contact to me Ted ? We used to call it a screw head. Wonder if it was slot or Philips. I've noticed that the Chinese don't use JIS much.

Hey! bilingual -- you should be thankful. ... I was laughing at the translation first up and reckon right away the item did not come built from Mexico...Nasty. Could it have caused fire if you did not notice? You can't have that fixed across the border can you?

Nice shot of a real antique there Ted. Look at all the metal used in the construction; hardly any plastics at all!
