Door open light stays on when door shut.

If the door seal is that bad that it is letting all of the cold out. Put the duct tape on the left, right and bottom edges. Just enough pressure to seal.

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.

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!

The microwave is not supposed to shut off if you have food in it. it is designed to stay running so you will not forget your popcorn.

check the door switch,i don't work on lg but on any other dryer if the wsitch is broke the dryer won't start and if the light is on the switch shuts off the light and dryer will start.if you send the model number i can look up the switch for you.open the door and look around the frame where the door closes into,there should be a push button switch or a little paddle that the door hits,when you push in on the switch it should make a clicking sound or i've seen the paddle broke off.hope this helps or if you removed any wires to the door switch you might of wired it wrong

have you checked the pump filter ?

Solved beeping problem.........Samsung SRS539HW . Have one of these and it is 6 years old. I had to replace the bottom hinge on the fridge side(right). Easy job but now constant beeping as if door is open, and light is intermittent. Found that there is considerable wear on the cable through top hinge of door and one of the wires from a magnetic reed switch in door had broken. I discovered this by shorting the two fine wires (white and pink/white) going to internals of fridge.No more beeping due to door opening and light now working correctly. Of course I no longer get a beep for a valid door open to long but cheaper than getting a refridgerator expert in.

Hello, it needs to be reset, There two reset buttons one for the frig/frez and one for the filter--drinking water/ice maker. GB...stewbison

if the refrigerator is beeping -- then this is a sign that the door switch is not working properly,loose or broken.
to stop the beeping --- press and hold the "lock/alarm" button on the control panel until the indicator light turns off. ( this turns off the 'doors open' alarm ) --- now if you get the door switch fixed and you want to turn the 'door open' alarm back on, then press and hold the " lock/alarm " button again until the indicator light come back on.

c...

sounds like the push button thats on the door jam in the front left or right door is stuck or bad
