Low temp alarm goes off on Kenmore upright freezer

The light may be staying on and creating heat, or the unit thinks the door is still open.

Or the door seal is worn and is letting cold out.

Or

It needs gas.

Have you put a thermometer inside to check the temperature? It should be 0'F +/- 2'.

The manual for this unit can be found here.

Try disconnecting power for about 30 seconds, and then restore power. This will reboot the control and maybe restart.

Kenmore Frostless Upright freezer model# 23971. The alarm sounded, all contents in freezer is frozen solid. We turned the alarm off, but the red light continues to blink. How do you reset the alarm and stop the red light from flashing? It has been 3 days now and every time we have check to see if the contents has started to defrost, there is no signs of defrosting, everything inside of the freezer remains frozen solid.

i had the same problem and it turned out to be the sensor, a $15 part. it pretty much controls everything related to defrosting.

alarm should go off when freezer reaches minus 18c or lower.

if it can be turned off it will be in the kickplate but the alarm will go off when it gets back down to temp

Use a freezer thermometer and tell me the actual temperature. Or at least store some ice cream and see if it stays brick hard. Unless I have some idea of the actual temp I can't tell if defective freezer or alarm

1)forget about the key you'll be disposing of this unit anyway
2)the alarm is to tell you that the unit is above ideal temp.
3)the unit isn't making temp due to refrigeration issue. if it isn't cold enough on 3 then 1 won't do it either.

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.
