You have 3 parts that control the defrost cycle: Defrost Thermostat, Defrost Heater, and Control Board. You will need a multimeter to ohm test.

Here's the multimeter I use:
Multimeter DM10T


You can get a multimeter at any hardware store too.

You will need to ohm test the defrost thermostat for continuity while its still covered in frost, and ohm test the defrost heater too. Unplug your refrigerator first!

If the defrost thermostat is not frosty, you can still test it in a cup of ice water, watch the video below. You'd need to keep the defrost thermostat in the cup of ice water at least 5 minutes before ohm testing it.

Watch this video to ohm test your defrost thermostat if yours is NOT frosty:

Here's your defrost thermostat and defrost heater for your model:

WPW10225581 Defrost Thermostat


WP2323198 Defrost Heater


The Defrost heater can be ohmed for continuity as well, make sure your refrigerator is unplugged before removing the wires from each part for all ohm testing.

Watch this video to ohm test the defrost heater with a multimeter:

If both the defrost thermostat and defrost heater ohm test good, then we know the control board is the culprit.

Here's the control board for your model:
Control Board W11174836


Let us know what you find.

my defrost does not look like this and I cant find it, the only white clip to the pip is not like the defrost, could it be missing or it the white clip is the defrost thermostat?

Added model number

We need the model number first.

Read it from the model number tag located inside the refrigerator section on the upper walls or ceiling.

it is WRS325SDHZ01, I ended up cutting something that was attached to the pipe and the fan stop working, and maybe other functions went away as well.

Sounds like a similiar issue I have with my WRS321SDHZ01. Frost buildup in 3-4 weeks would eventually choke the evap coils then warm on both sides. My issue was the cntrl board but I see you replaced that already.

What did you cut? attach a photo or two please of what you cut and where you cut it from.
