Good Afternoon Friend,

I understand that the temperature alarm light is on for your Frigidaire freezer, model# FFU21M8CW. This feature is designed to provide a warning of a possible malfunction. If the temperature of the food rises to a level unsafe for long-term storage, the buzzer will sound. The red light, if equipped, will also glow. The Temp Alarm feature operates on household electricity. If power fails, the alarm will not function. An ON/OFF switch allows you to deactivate the Temp Alarm when not wanted. Your freezer is shipped with the Temp Alarm in the OFF position. After your freezer has run approximately 4 hours, the red light, if equipped, will go off. Then you may activate the Temp Alarm without the alarm sounding. Press the ON switch to activate the Temp Alarm. To deactivate, press the OFF switch. If the alarm sounds, be sure freezer is properly leveled, and the door closes freely, and seals properly. If you suspect a technical malfunction, call an authorized servicer immediately. Hope this is helpful.

-Best Regards-

Hello Michael - Sounds like the temperature control was accidently turned OFF. When this occurs the temperature control turns off the compressor, but does not disconnect the power to the light bulb or other electronics. Let's try activating the freezer by pressing the UP arrow until display shows "4" or desired setting. Allow 24 hours for temperature to stabilize. For future reference you can lock the control to keep from accidently changing the temperature setting. I ask that you please follow up with a comment on the post, at your convenience, to advise if further troubleshooting is needed or if the unit's status has changed successfully. Thank you.

The defective door seal is the problem.

Check the door gasket near those shelves.

Make sure the condenser fins or tubes have adequate air flow for cooling (it looks a bit like a small but fat car radiator). In most freezers, this will be in the bottom in the back. You may have to remove a vented cover to check this. Usually there is a fan blowing air through the condenser. Carefully vacuum out any dirt in the condenser (the fins are delicate and bend easily), and verify that the fan runs smoothly when the compressor is running.

Put a thermometer in the freezer right by the cold air inlet to verify that the refrigerant is doing its job. It should read 0 degrees F. or below (-18 degrees C). If it doesn't get down that far, the compressor needs to be recharged or replaced.

If the door has been hit hard (somebody falling and slamming into it) the door insulation may be damaged there. Check to see if the outside of the door feels cold there compared to the rest of the door. If it does, the door needs to be repaired or replaced.

Not sure if u still need help but the first thing I would do is remove the grills on the front and back and vacuum out the fins on the condenser...dust and grime collects here and will cause the unit to overheat and not cool properly....sometimes an air compressor can be used or air in a can for the hard to reach places.
Tr this and see what happens...good luck

If the control is "ON" and the compressor is not running, you will need a start relay... Make sure you didn't accidentally turn it off by pushing food against the control knob!

Press and hold the Control Lock key for three seconds
to activate or deactivate the function. The Control Lock
feature prevents the user from changing the temperature
and freeze settings. At the first press of any key, the
key press click tone will be heard and the display will
show "LO", but no other change will take place. Holding
the Control Lock key for three seconds will activate or
deactivate the Control Lock feature. After three seconds,
the accept tone sounds and the Control Lock LED (if so
equipped) is activated. In lockout mode, when any key
is pressed, the invalid key tone will be heard and "LO"
will be displayed for 1 second. When the lockout is
deactivated, the Control Lock LED is turned off and the
display shows "UL"

if this does not work unplug the freezer for 30seconds then plug it in. if all of the above fails replace the control.

The red light provides visual assurance that the freezer is receiving operating power.

Good Morning Friend,

I understand that your Frigidaire freezer, model# LFFU17F5HWC, seems to be stuck in a defrost mode. Your freezer is supposed to automatically defrost for 30 minutes after every 12 hours of compressor run time. I suggest resetting your appliance, be either unplugging it or shutting the power off at your homes circuit breaker, for 3-5 minutes. Restore power and watch to see if it is still stuck in defrost mode. I ask that you please follow up with a comment on the post, at your convenience, to advise if further troubleshooting is needed or if your washer status has changed successfully. Hope this is helpful.

usually means low freon... (of) and evaporator fan failure. can you hear the fan running in the freezer portion?...

Frigidaire 20.3... | Answered on Jun 06, 2015

Your drain probably is stopped up with debris. The reservoir just catches the water and then evaporates. Clean the drain out with a small brush and thenour a cup of water down it to clear the line.

Hello Tim;

My name is Peter. I am a retired field service refrigeration technician.

You do not have a major problem. This is a easy fix.

When you open your freezer door and then close it you are pushing air into your freezer. This is where the sound is coming from.

On your drain tube in the back that goes to your drain pain there might be a black rubber grommet on the end. The initial design was to put this restrictive rubber element from having air go up your drain tube. Over time the rubber dries and restricts the defrost drain and retains water.

If you have this do what I do on service calls - remove it and throw it away.

You may have a snake type drain tube to your drain pan. Once again the manufacturers engineers, with no field experience, decided to put a loop in the drain tube to prevent warm air getting into your unit. Well, the defrost condensate gets caught in the loop. That is where you are hearing the noise.

The drain tube use to be a straight tube. And so, that is where we are back to. It worked fine. Manufacturers changed it and now us technicians put the straight drain tube back in.
