    I have a Frididaire Gallery 20cf upright freezer 10 yrs old. Temperature warning light blinks, ice builds up on the floor of the freezer..( Its an auto defrost moded). The drain is not plugged. Sears repairman serviced it but still has the same problem. Although I adjusted to a colder setting the temperature remains about 12 to 14 F. Any suggestions?

    I have a frididaire chest freezer model GLFC2528FW2. The "too warm" signal light and beeper are coming on but the freezer temp is below zero. I have adjusted the temperature control, replaced it, but this has not solved the problem. Also, I have replaced the "high voltage assembly" and the unit worked great for awhile, but now it is back to the same old problem. What do you think might be the problem? The freezer is about 2-3 years old.

Freezer losing temperature

Hi Julie. I'm Roger. It sounds like the operating thermostat is not working When not in the fast freeze mode. Can you here a click sound from the thermostat when turning the temperature up and down short of fast freeze? We normally charge them to operate at -10 to -20 degrees. The inside temperature will normally only reach a temperature around 18 degrees warmer. The operating thermostat should allow you to regulate its temperature any where from that capability up to where you want it. See if your thermostat makes a clicking sound when adjusted. The warning light comes on because it knows the box temperature is higher than it is set for and is warning you of that. If it uses a printed circuit (PC) board, the click will dot be very loud. listen closely. Let us know how this turns out for you. We have very good refrigeration techs. here. Someone else here may have an idea too.

I have a Zanussi Freezer Model ZFT710FW. The alam and red light occasionally go off, although everthing appears OK. Temp OK, door seal looks good, etc. After some time the red light goes off of its own...

Red Alarm Indicator Light
Under normal operating conditions, the internal temperature of the freezer will ensure the long-term conservation of the stored food. When such temperature rises above a certain level (-12 °C), the appliance will trigger an acoustic and light alarm. The light alarm is a blink red light (Red Alarm Indicator Light), while the acoustic alarm is an intermittent sound.
You can stop the acoustic alarm by pressing the Acoustic Signal Stop Switch once.

When switching on the freezer for the first time, the Red Alarm Indicator Light will blink until the internal temperature has reached a level required for the safe conservation of frozen food.

Fast Freeze function
If more than 3-4 kg of food is to be frozen:
1. Press the Fast Freeze Switch for 2-3 seconds to activate the fast-freeze function 6-24 hours before placing the fresh food in the freezer, the Yellow Fast Freeze Indicator Light will illuminate. The compressor will now run continuously, to ensure that the fresh food is frozen as quickly as possible.
2. It is possible to deactivate the function at any time by pressing the Fast Freeze Switch for 2-3 seconds.
3. Place the foods in the freezing compartments (indicated with graphics).
4. Once the food is completely frozen (it may take up to 24 hours) you can manually switch off the fastfreeze function by pressing the Fast Freeze Switch for 2- 3 seconds and the Yellow Fast Freeze Indicator light will also go out.
5. Move frozen food from the freezing compartments into the other compartments (storing compartments) to make room for another freezing.

If the Fast Freeze Switch is accidentally left on, the fast-freeze function will be automatically switched off 48 hours later. The Yellow Fast Freeze Indicator light will also go out.

I believe that you all understand. If you intend to freeze larger amount of food then certainly a few hours before some shopping switch on the fast freeze function.

Does the light on the outside of freezer stay on . I bought a used freezer. It is a frigidaire commercial upright (frost free) Does the light on outside of freezer stay on all the time? I have no manual....

Normally there is a Green light showing that power is on

A Yellow one for fast freeze and a Red one for under temperature

The outer casing is well insulated from the inside otherwise the freezer motor would run none stop without cooling the contents so the temperature of the outside casing will reflect the room temperature not the intenal

I have an older commercial upright Hobart freezer. The freezer seems to operate fine, cycling but always returning the compartment to zero degrees, until all of a sudden the temperature went up, well...

In most cases, an evap that freezes up is either an air flow problem or no defrost cycle. Older Hobarts have mechanical defrost time clocks. It could be locked up i.e., not running so no defrost cycle.
It could be coming out of defrost too early because the sensor that monitors the evap temp is not working properly.
The door could not be closing. If left cracked open, it will freeze up every time as unit never hits temp., keeps unit running. Warm air is seeping in and the moisture freezes on evap.
Lastly, the defrost heater(s) may not be working. Burned out, shorted, broken wire, etc.

Good luck and hope this helps.

Believe it or not, but it is normal. Especially when just turned on. As the internal temp. gets colder so will the temp. on the side get cooler.
