The alert notification is from a u-line refrigerator and beeps even when door fully closed

It looked like your model does NOT have an external ice/water control panel which has caused beeping problems on some models.
For your model I would try the following....
Door Alarm
The main cause of a beeping GE unit is an open refrigerator door. Some models are equipped with an internal door alarm, which trips when the door remains open for 3 minutes or longer.
One way to check this .... put your smartphone in the refrigerator on video mode and close the door. The light should go off with the door shut. If the video shows that the light stayed on when the door was closed ... then it reinforces that something is wrong with the switch/alarm. Repeat video for the freezer.
Door Seal
If beeping persists after the freezer or refrigerator door is closed, the door seals may be blocked or so dirty that the internal door alarm is tripped. The seals can be cleaned with a soft cloth and warm, soapy water. Also, an item inside the refrigerator may be preventing the door from fully closing.
Cooling System
Reactivating the refrigerator's cooling system includes a beeping noise. When the refrigerator is off, the "Off/Off" light appears on the door display. When the "Adjust Freezer" and "Energy Saver" buttons are held down for approximately 3 seconds at the same time the beep sounds and the "Off/Off" indicator disappears. Hold the "Ice Off" and "Freezer" buttons to activate the cooling system inside of the fresh food compartment. A beep signals the system is activated. The beeping should stop after the cooling system turns on. If it fails to stop, try unplugging the power cord to reset the connection.
Power
The GE's internal door alarm can get stuck. Try unplugging the refrigerator for about 10 seconds and then plug it back in. If the beeping continues, the internal door alarm might be broken or defective. Contact the manufacturer or a technician for further assistance. One way to check this .... put your smartphone in the refrigerator on video and close the door. The light should go off with the door shut. If the video shows that the light stayed on when the door was closed ... then it reinforces that something is wrong with the switch/alarm.

Good luck on your troubleshooting!

Since you did not mention what make it is .
Its usually dirt in your door seal causing your refridgirator to understand its not closed since its not sealing properly . clean the door seals and try .
Or there is a technical glitch in electrical system and you need a repairman .

Also there is usually a way to disable the alarm and you need to check your user manual for that to disable it ill its fixed .

Fridge keeps beeping or buzzing: The following is for Frigidaire models but others can be addressed similarly.

Several Frigidaire refrigerator models have an electronic control panel on the freezer door the owner can use to adjust the internal temperature, dispense ice and water and receive notification about issues such as the need to replace a water filter. The refrigerators also emit a beep for various actions and as an occasional alarm. Determining what causes the beeps necessitates some troubleshooting.
Temperature Controls ·A Frigidaire refrigerator's display panel blinks when the control panel is touched to set temperature controls. After pressing "Freezer Temp" or "Refrigerator Temp" on the keypad, press the arrow buttons within five seconds to increase or decrease the desired temperature. If you do not press the arrow buttons within five seconds after pressing "Freezer Temp" or "Refrigerator Temp" on the keypad, the refrigerator beeps to indicate the current setting will stay in place.

Door Open ·When you leave the refrigerator or freezer door open, the refrigerator beeps. Also, the "Door Ajar" indicator illuminates on the appliance's display panel. Shutting the door and pressing "Alarm Reset" stops the beeping and turns off the "Door Ajar" indicator light.
·The Frigidaire refrigerator has a control lock feature that prevents use of its control panel or dispensers when the unit is locked. When the control lock is active, a beep sounds when a keypad or dispenser is pressed. Release the control lock by pressing the "Control Lock" icon for three seconds. A beep will sound, and the icon's light will go out.
Power Reset ·A power reset is occasionally necessary if the Frigidaire refrigerator's control panel does not work normally or a reset function on the keypad does not work. A power reset involves disconnecting power to the refrigerator by unplugging its power cord from the electrical outlet, waiting 30 seconds and plugging the power cord back into the electrical outlet. When the control panel resets, a beep sounds. If the refrigerator beeps even after a power reset and the beeps' source is not known, contact Frigidaire.

I don't know of a way to close specific ones when they come up. You can always disable applications from System Preferences; change between Banners, Alerts, and Badges; and even turn off Notification Center all together.

Is this a door alarm? ARe you sure the temperatures are good? or are they sort of ok, indicating it is getting warmer. the filter is only for the ice maker and the water dispenser.

First check to see that the door switch is closed fully when the door is closed. Tape it fully shut to make sure
