samsung rf263 new defrost sensor location for better defrosting

[Nook]

My frig is icing over in the frig compartment.  I have found how to disassemble and clean/dry it out and have done so.

Both sensors (on the coil and in the fan cover) check good.  The heater is 114ohms.

The black thermal is Meg ohms.  I didn't find what its readings should be elsewhere to know if it is good or not.

I would like to confirm the "new defrost sensor" location, but apparently mere regular people can't post pictures.  If someone can provide me an email address to send to, I have pictures.  Another thread for a very similar samsung model described moving the sensor to get longer/better defrosting; I just want to confirm I have the right location.

The sensor (yellow wires) was originally attached on the far upper right, just after the refrigerant line goes from the tiny little straw to a pipe around some heat shrink.  The instructions elsewhere said move it to the top leg.  For my model, that is at the opposite end of the piping for the coil, right at the point where the piping goes back to copper and about 6" before it exits the interior compartment.

I also have an additional loop that is about 6" of copper, comes in the same hole as the tiny straw then just turns around and goes out the same hole as the other end of the coil.  That is all copper, but clearly has a solder joint in it.

I also would want to confirm if the black thermal is good or not.

Thank you.

Sounds like you're describing the bimetal. It should read closed, about 0 ohms. Your reading shows it is out of spec.

Sure you can! Just upload the photo to any free image hosting site and then post the link here.

Move the defrost sensor to the top of the evaporator inlet tube (just below the cap tube joint).
