Out of the trash, I got a tower electric room heater, with a fan.
About 18" high, like a loaf of bread standing on its end.
On the plastic grill in back (BACK), there is a little black plastic
4-sided box, (no top or bottom and the box is on its side, so that air
can go from outside the heater to inside) maybe 2x3mm, with maybe a
thin wire going across it and a 2-conductor insulated wire going to
one of the little circuit boards that control it.
On the circuit board the pins that match the connector are labeled
What do you think TH stands for, what do you think this gizmo is?
The cylindrical plastic fan blade is messed up and I don't want a room
heater anyyhow, so I'm going to throw this away, but I just can't
figure out what that box etc. is for.
