Turned off freezer to defrost and clean. when turned back on alarm light flashing and fan only engages for a second before cutting off.

Hello Deena;

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

There is no reset for the alarm. The alarm goes off when you are not maintaining temperature.

During the time the door was ajar, warm air got into the freezer either icing up and locking the cooling fan or forming a block of ice on the cooling coils (Restricting cooling air flow.)

The best thing you can do, unless you want a $300.00 plus service call to defrost everything, is to turn power off to the freezer. Open the freezer door. Have plenty of old towels to soak up the water in the bottom of the freezer as it defrost.

You did not provide a model number which is located on the inside wall of the freezer. Every 8-10 hours your freezer will completely shout down for 20-30 minutes where only the light works and the defrost heater turns on. The ice build up is too much for the defrost heater to handle.

In some freezers the defrost mode is in the control board, in others it is a separate component that you can repeat trip using a flat head screw drive.

The green light should be a normal running light and the other one, either yellow or red(ish) should be a high temp alarm. Check the contents to make sure they are still reasonablly frozen and if not start finding the cause....Is the condensor fan motor running correctly? Is the condensor coil clean and free from dirt/lint/fuzz which serves to restrict the transfer of heat? Is there an excessive accumulation of ice build up indicating possibly a problem with the automatic defrost cycle?

Because it does not achieve the correct temperature (for example: -18 degrees centigrade).
For a more precise answer I need more information.
A lot of things may be incorrect:
- Doesn't work defrosting cycle
- The cooling fan is not working
- Too much ice on the evaporator battery
- Faulty thermostat or NTC sensor
- Faulty cooling system (gas leak)
- Compressor
- Electronic

Cut off the circuit. Everything runs on the system together so you may need to contact someone that knows what they are dong.

You have a problem with the ADC.

Frigidaire has also jumped into the market with an adaptive defrost board. The fresh food section light switch and light bulb must work. To initiate a defrost cycle, open the door and push the light switch in and out 5 times within 6 seconds. The compressor and fans should shut off and the defrost heater should come on. Open the door and push the light switch in and out 5 times within 6 seconds to remove the refrigerator from the defrost mode and back into a cooling mode.

This product comes equipped with an Adaptive Defrost Control (ADC). To activate manual defrost, press and hold the Freezer temperature UP (WARMER) key while pressing the Fresh Food temperature DOWN (COLDER) key 5 times within 6 seconds. A "d" in the freezer temperature window and "F" in the refrigerator temperature window will display when the heater is activated. To deactivate manual defrost, press and hold Freezer temperature UP (WARMER) key while pressing the Fresh Food temperature DOWN (COLDER) key 5 times within 6 seconds. "d" and "F" will be displayed until the defrost cycle is complete. (approx. 8 minutes)

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.

Freezer Temp. shoud be 0 to -5 Deg. if to warm it will set off the alarm. try unpluging or turn off power to freezer for 1 or 2 min. to see if it will reset.

I turned the fridge and freezer off using the circular dials, I then turned the unit off at the mains. Left it for a few minutes and then turned the power back on. I then turned the circular dials to "max" and then depressed the super cool and super freeze buttons to turn this facility on. This time they came on normally (not flashing) and no alarm sounded. The fridge and freezer then started to get cold. Once the unit had been running for several hours I then turned the dials to the 3/4 mark and depressed the super cool and super freeze buttons again to turn them off. Over night the fridge and the freezer appear to be working properly so I hope that my problem is solved. Maybe the unit just needed to "settle" before being switched on?

My wife solved it for me :-) You turn the alarm off with a switch at the bottom. The alarm turns off, but the light stays red for another 4 hours. After that the red light goes off too, and you can turn the switch back on without the alarm going off, if the freezer is back to operating temp.

If the fan motor is running at the compressor you should first replace the compressor start relay.
If the fan motor at the compressor is not running replace the defrost control.
