I have a Kenmore refrigerator top mount freezer, which quite often starts sounding 3 beeps.

There will be a pair of round 'twist' adjusters mounted somewhere inside the refrigerator. Some are mounted high, on the panel where the flexible door seal sits when the door is closed. Others are mounted on a side panel inside the actual refrigerator. Generally these will be set to the middle position.
*NOTE* If the refrigerator/freezer is full of food it will struggle to get to temperature. It needs to be Empty with the power On for at least 24 hours to get to it's working temperature range.

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.

kenmore elite, alarm kept going on and b flashed on and off. I finaly figured out on bottom of freezer there is a battery door open it and change 9v. thats it,

Your Defrost drain is cloged. you will need to remove the back wall to get to the drain and then defrost it with hot water. have lots of towls ready. and make sure the hot water is poured in the pan under the evpaerator. you might also look at the back of the machine to see if there is a drain tube, some of those top mount have a tube on the back.

once the water starts flowing your good.

there is a reason we just need to find it,open the doors one at a time and press the switch that turns the light off. do they all work? what is the complete model # starts with 3 digits then a period then 6 or so more #s.

It sounds like you may have a compressor that is working hard against high pressure due to a dirty condenser or a condenser fan not running or blocked. If all is well otherwise, the mounting springs inside the compressor may have broken or are weak. The only fix then is a new compressor.

Replace your thermostat and will work like new again

Look inside the fresh food section behind and inside the control panel for a defrost timer and circuit board. Let me know when and what you find. Please unplug first, Thanks, Sea Breeze
E. Cold Control & Defrost Timer/Automatic Defrost
Control
These parts can produce a snapping or clicking sound
when turning the refrigerator on and off. The timer also
produces sounds similar to an electric clock.

I don't believe this model has an alarm in it. The beep you hear maybe the evaporator fan motor, also if there is an icemaker in the frig be sure it is turned off
