Can anyone identify this part?

Hi Guy's,

They are basicly Thormostatic Sencing Bulbs that work both ends of the thomometer.. [heat/cool]

Paladin, looks like yours was replaced at one time....

So should I just mount is somewhere in the tunnel area as Craig was saying it should have been?

Since I'm messing with it it there was way to test it before putting it in? Apply some heat and use a DMM and look for changes? 

[Nick Badame Refrig/ACC]

Yea,

You should get OHM's out of it and sure change when heat is applied..

I would mount it in the general area that it came out of.

Good Luck

I found it stuffed up into an air duct that won't be used, I tore it out. I can see how that might have helped the air but not sure how it would have been able to do anything about heat where it was......unless the heat and air combined in duscting in the wall and wen to vents. My walls were all replaced predating my ownership.

If you look at your center tunnel in the first bay, drivers side, next to the A/C j-box, you should see a round plate. This is where the original was located.

The heat and a/c shared the same duct, so if it was shoved up into the side duct, it could have been a replacement for the original.
