Topfreeze,

With the description you gave, you need the diffuser,

Part number: AP3046080

Topfreeze,

Here's the Refrgerator cold control information:

You have 3 wires and the green ground wire,

Orange/Black, terminal #2, is the common lead into the control.

Yellow/Red,terminal#3, is the power lead to the damper motor on the cold(lower settings).

Black/Yellow,terminal#1, is the power lead to the damper motor on the coldest(higher setting).

So,

With the cold control at room Temperature:

The orange/black terminal to the yellow/red terminal should be a closed circuit on the lower temperature setting on the control.

The orange/black terminal to the black/yellow terminal should be a closed circuit on the higher temperature setting.

Something I used to do,

Take a glass of iced water,or ice cubes, while you're testing, insert the end of the control thermal bulb and put it in the water,or cubes, and watch your meter, the circuit should open,

If you warm the end of the thermal bulb(warm water or your hand), the circuit should close again.

This should get you to where you need to be.
