Testing TXV

[carlb7]

So the TXV bulb is taken off the line and the cabnet is closed back up with the bulb on the outside dangling. Of course it is another 70 degree mild day. Here are the readings.
High Pressure=165
Low Pressure=65
Suction Temp=41
Liquid Line=79

Now the bulb is submerged into ice water. After about 5 minutes here are the readings.
High Pressure=175
Low Pressure=66
Suction Temp=42
Liquid Line=79

One other observation. When you put your ear up to the liquid line you can here a change in the sound of the refrigerant flow when the bulb is submerged into the ice water.

Is the TXV working or barely working or is it okay.
