Frigidaire upright--"Hi temp" warning light on door. Don't know why freezer temperatures are so high (into 30s), food is thawing. Electrical seems to be fine. Have not noticed problems with door. New freezer--about two months old. Technicians said they leveled it when installed. Thanks for your feedback!

Warning light (red)
If the temperature warning light (4) lights up, it
indicates that the temperature within the freezer has
reached a level where the safe food storage is no
longer ensured. When the freezer is first switched on, the warning light will stay on until the temperature has dropped to
a safe level for the storage of frozen food.

Temperature acoustic alarm
This appliance incorporates an alarm which gives off
an audible signal whenever the warning light comes
on. This signal can be temporarily stopped by
depressing the push button for fast-freezing (6).
The fast-freezing push button can be released as
soon as the warning light is off.

Open door acoustic alarm
This appliance also incorporates an alarm which
sounds if the door is left open for more than 60
seconds. The signal will be stopped when the door is
closed again.

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.

Hi Susan Abboud - Modern freezers have increased storage capacity and keep more even temperature that may require the compressors to run longer but use less energy. Was the unit disconnected previously for any reason? If so, freezer requires a minimum of 4 hours to cold down completely. Confirm that the temperature control is not set too cold and that the door is not being open frequently. A dirty, cracked, worn or poorly fitted door gasket can allow warm air to enter the unit causing it to have to run longer to remove the warm air. Leaks in the door seal will cause freezer to run longer in order to maintain desired temperature. Cleaned the gasket, if it is too damage then it will need to be replace. You can check and see if the door seal is bad by, placing a dollar between the gasket and cabinet. Check to see if the door is being blocked by anything stopping it from closing properly. If nothing is stopping the door then replace gasket. Keep in mind that there should also be at least 4-6 in of air space on all sides of the unit. If freezer is built in or has items stored on top that cover the unit, the can cause long run times, high temperature in the freezer and premature failure to the unit. Do not block the toe grille on the lower front of the unit. Sufficient air circulation is essential for the properly operation of your freezer, about 3 inches around the unit.

the red light is a temp warning light and will not respond unless the temp goes way above the set temp

dear sir/madam



i think its tempretor sensor /thermostat problem please try to find thermostat needele and keep in right position , and check its tempretor satting if it,s need to reset please reset it . i hope after that it will working good. if not please try to contect your freezer maintanance perssonel for repair/reset your freezer .

please vote!

i would make sure that the coils are all clean, inside and out. make sure the fan runs on the back, the water pan isn't over flowing.

I believe you freezer has sprung a Freon leak. You described it and if it changes levels is a way of measuring what Freon you have remaining. Sometimes they can be repaired it depends on how they were built. Hope you did not loose much food, Sea Breeze

Hi, Put a thermometer in the freezer and see if it gets down to 0 to 5 above zero. If it is not getting that cold, something is wrong. If you had frost building up behind the rear panel, there is a defrost problem.
Please let me know the temperature and I can assist you further.

If it started to cool again the compressor was running. Check the condenser and make sure it is clean. Provide as much air movement through the garage as possible . 100 degrees is a high temperature to be operating a refrigerator in.
