We have the Kenmore frost free, 20 cu. ft. freezer, model 2539260411, purchased in about 1995. Usually about 2:15 p.m. daily, the freezer "temp alarm" beeps. It continues to beep until we press the reset button. The temperature in the freezer stays consistantly low, so that is not the problem. Any suggestions? Thanks. Charlie

Hi most deep freezers operate at 0 dergrees. your model may have 2 temp zones. 0 or 20 deg.I'm gessind that your sensor is going off when the defroster is on to melt ice (defrosting). Lower the setting. monitor and repeat as needed. if it continues you may need to replace the unit or ad freon. If the unit is over 13 years ge a new one.

Good Luck

its a temp alarm

i think you allow fresh air to flow in the compressor side or try and get a refrigerator fan for it.

I think you meen below 20 . Its mostlikely low on freon. if only half or less of the evap coil has frost , you low on freon. Then you have a leak in the system.

Is the compressor running the whole time? If so may have a problem with a refridgerant leak....check the compressor in the rear of unit, feel if its hot....may be as simple as a relay.

Yes you need to replace it,if dont will have bigger problems.

You will need a professional at this point.

You may want to check the compressor area of the unit.There may be something on the coil or fan blade.(Packing foam,paper, etc)

might have a defrost problem check to see if it is building up with on the back panel if it is you need a defrost timer or limiter or heater or fan
