Are the buttons being pressed the freezer side + and the fresh food side -?

this is press on the freezer side. + and -

Pressing the freezer + and - will activate the diagnostic mode. From what I am finding, it looks like this is in demo mode which should be able to be activated and deactivated by pressing and holding the freezer + and the fresh food - buttons at the same time for 10 seconds. If you do this, does the display stop showing off and switch to showing the temperatures?

when press and hold the freezer + and fresh food - for couple sec, it have sound but still showing OFF on the display panel.

Are the buttons being held for 10 seconds or are they being held for less? The only other option I can think of is pressing the temperature - button on the fresh food side, or the freezer side if that doesn’t work. The next step after that would likely be a dispenser control failure.

I did press more then 10sec. Next test is it only pressing the - button on the fresh food ?

In some models, pressing the temperature down button would disengage the system off. It should not apply to this model, but is still worth trying just in case there is something glitching in the program.

I tried, just pressing and hold the - button on Fresh food. after that press and hold on - button on freezer side. nothing happen.

It sounds like the dispenser control is locked up. This could have been caused by water damaged, if water got onto the electrical pins of the control when the water line burst.

And i can feel the refrigerator and freezer still cool, just that not as cool as before. Freezer stuff still good not seeing defrost.

Replacing the dispenser control would likely allow for good communication to the main control. If the compressor and fans are operating, it indicates the dispenser control is doing its own thing while the main control is attempting to do what it should. This can affect temperatures and other functions. From what occurred prior to the failure, and the fact that the dispenser control will not properly accept commands, it would point to the dispenser control being the most likely cause of failure.

How can i order this dispenser control? is this the one?

In the website that I referenced with the link, there should be an add to cart button. If that is clicked, it should allow for a checkout process to be done by viewing the cart.

the fridge and the freezer is not cooling. The dispenser control will able to resolve the problem right. Yesterday still can feel the cool, but today is not.

The system can be cool for a bit after the display shows OFF, but it will eventually warm up to room temperature due to the compressor and fans not turning on. Since the dispenser module will not accept the input to turn the system back on, replacing the dispenser control is the most likely fix for this issue.

Can you advice any procedure to install the dispenser controller and start back up after installed?

i purchased the dispenser controller from Appliance Parts Pro..

With the power supply cord unplugged, putty knife (preferably a thick plastic putty knife) would be used to remove the dispenser module by inserting it in the bottom seam to disengage multiple locking tabs while pulling slightly forward. The locking tabs should be in the marked areas in this image.
