My name is Peter. I am a retired field service refrigeration technician.
There is no reset for the alarm. The alarm goes off when you are not maintaining temperature.
During the time the door was ajar, warm air got into the freezer either icing up and locking the cooling fan or forming a block of ice on the cooling coils (Restricting cooling air flow.)
The best thing you can do, unless you want a $300.00 plus service call to defrost everything, is to turn power off to the freezer. Open the freezer door. Have plenty of old towels to soak up the water in the bottom of the freezer as it defrost.
You did not provide a model number which is located on the inside wall of the freezer. Every 8-10 hours your freezer will completely shout down for 20-30 minutes where only the light works and the defrost heater turns on. The ice build up is too much for the defrost heater to handle.
In some freezers the defrost mode is in the control board, in others it is a separate component that you can repeat trip using a flat head screw drive.
Good Afternoon Don, thank you for allowing me to assist you!
Did the unit previously experience a power loss? If
the temperature of food rises to an unsafe level, the red light will glow.
First, deactivate the alarm to the unit by unplugging it or flipping the
household circuit breaker. Wait approximately ten minutes and then turn on the
unit. After deactivating the alarm and the unit has run approximately four
hours, the red light/alarm should go off on its own. If the red light/alarm
continues to stay on, the freezer may possibly have a communication problem
with the control board, temperature control or a wiring harness. If this is the
case, I would recommend connecting with an experienced technician to determine
the underlying cause.

Sounds like frost bulidup from door being left open warm air gets in making frost and ice. Need to turn off for 24hrs or so to let all the ice melt compleatey then turn back on keep door closed run for 24hrs check Temp. shoud be about 0 to -5 Deg. if good start using.
If the defrost timer sticks in the defrost mode,yes. Normal defrost time is 30 minutes or less depending upon which timer is installed. If it happens again,locate the defrost timer and turn the dial manually to see if the compressor comes back on. If so,replace the timer. It is probably on the rear near the compressor. Some are under the front behind the dust guard.
My wife solved it for me :-) You turn the alarm off with a switch at the bottom. The alarm turns off, but the light stays red for another 4 hours. After that the red light goes off too, and you can turn the switch back on without the alarm going off, if the freezer is back to operating temp.
Having the door open has introduced an excess of humidity and therefore condensate/ice into the freezer coils. The coils are therefore iced over. You have choices depending upon your skill level. You might: allow the unit to sit unplugged with the door open until the excess ice thaws out and wets the floor underneath, which may take from 6 to 24 hours. You might: do this, adding some heat source in the freezer to accelerate the process. You might: locate the defrot timer, advancing the timer until a click is heard indicating the unit is in defrost, and repeat after about 15 minutes to defrost the unit with it's own heater. You might: let it recover just as it is but it will take a couple of days to clear itself.
if the alarm is sounding its probably trelling you the freezer is at too high a temperature. plug it in and leave it plugged in, it can take several hours to re freeze
Our manual says it can take our freezer up to 48 hours to get back to the correct temperature. I found that to be the case when we loaded it fully for the first time.
you have a refrigeration issue partner let her go 16 yrs. is good service you can replace it for 3 to 5 hundred the repair will be that IF you can find someone with the r-12. don't go for a top it off and go deal the food you lose is to expensive for that to be economical.
