I've never seen this

[Pat Pixley]

Ok I'm breaking down my Secectivend A9  and I came
 across some wire that came out of the wiring harnes
 and ran up inside the cabinet and all around the opening
 of the main door.
 I've never seen this before. Any ideal's ??
  Thanks

Is it a bare wire?
So it ran all the way around the opening?  Can you tell what it stopped at? '>

[Pat Pixley]

Well it not bare its coated  and it loops around back to the wiring harnes.
 Now I'm going to say sorry for the bad photo right now
 but trust me there is two ends in my hand.

Maybe it is standard wiring for the machine in case an optional lighted sign or something was  to be mounted to the top of the machine or something like that.
You got me?'>

I would think that it is a mullion heater.

Yeah, I just hate it when my mullion gets cold. '>

Sorry, couldn't resist. '>

        Jerry, what is a mullion heater?  I have found this wire surrounding the selecton window of the main door.

I'll through in my 6 cents(six sense)...

Although I cannot confirm this and this is in conjunction with Glen's statement

I think these strips are installed on machines in cold climates to keep from freezing the doors. These seem to be located in areas of the machine that are prone to condensation which will freeze in colder climates. This could prevent a paying customer from retrieving their drink...
On older machines, you may have seen a flat resister mounted behind or on the coin mech to keep from freezing up. I'm assuming this is a similar principal...

First thing Mark,Very good  '>   second
this does run around the inside of the cabinet  for the main
 door not the bottle door .
Now there was a  mounting bracket screwed on top
 I just don't know if it was original or not, plus there was no hole for the wiring to come up though.
 SO I don't know if I should just pull it or not ?

 Thanks

An insulated wire wouldn't transfer any heat - would it?
I looked up mullion in the dictionary and a mullion is a divider of some sort on window panes. What it might have to do with a vending machine, I can't figure out.
If there was a mounting bracket on top, I will stick with my first guess. Unless you want to put a light of something on top, I would leave it off.
