Hotpoint FZFM171 freezer door left open all night, has defrosted and the 'super freeze' light and alarm light wont stop flashing. How do we fix it?

Something to think about from the manual for your freezer. Also I would check the temperature of your freezer with a thermometer to make sure it is freezing ok .Troubleshooting
If the appliance does not work, before calling for Assistance (see
Assistance), check for a solution from the following list.
The green POWER indicator light does not illuminate.
• The plug has not been inserted into the electrical socket, or not
far enough to make contact, or there is no power in the house.
The motor does not start.
• The appliance comes with a motor protection control (
see Start-
up and use
).
The indicator lights are on but the light is dim.
• Pull out and reverse the plug before putting it back in the socket.
a) The alarm sounds.
a) The refrigerator door has remained open for more than two
minutes (the buzzer will stop sounding when you shut the door) or
the correct switching-off procedure was not followed (
see
Maintenance
).
b) The alarm sounds and the two yellow indicator lights
flash.
b) The temperature in the freezer is too high. Check the quality of
the food products and dispose if necessary.
+ buzzer =
Heating is excessive
c) The alarm sounds and the two yellow indicator lights
as well as the green one flash.
c) The temperature in the freezer has reached a dangerous level.
The food must be disposed immediately.
+ buzzer =
Heating danger
b/c)
In both these cases the freezer will maintain a temperature of
about 0°C so that the food does not re-freeze.
To turn off the acoustic signal open and close the refrigerator door.
To restore normal operation bring the FREEZER OPERATION knob
setting to
(off) and turn the appliance on again.
The green POWER indicator light flashes.
• The appliance is not operating correctly. Contact the Technical
Assistance Centre.
The refrigerator and the freezer do not cool well.
• The doors do not close properly or the seals are damaged.
• The doors are opened too frequently.
• The OPERATION knobs are not on the correct setting (
see
Description
).
• The refrigerator or the freezer have been over-filled.
The food inside the refrigerator is beginning to freeze.
• The REFRIGERATOR OPERATION knob is not on the correct
setting (
see Description
).
• The food is in contact with the back inside wall of the refrigerator.
The motor runs continuously.
• The SUPER FREEZE button has been pressed (rapid freezing):
the yellow SUPER FREEZE light is on or flashing (
see
Description
).
• The door is not closed properly or is continuously opened.
• The outside ambient temperature is very high.

The light will flash until the freezer gets cold enough probably around zero degrees. Be sure door is sealing tightly. This can easily be checked by opening the door and putting a dollar bill between the door seal and the cabinet and closing the door. Close the door and tug on the dollar bill there should be a little resistance there if the seal is sealing against the cabinet. check it in several places

You will need to unplug and defrost the fridge for a few hours then replug the power. Leaving the doors open allows moisture to freeze on the evaporator while compressor continues to run confusing the control board

I now have these kinds of refrigerators and freezers to maintain, and have found some will take as much as 18 - 24 hours before the lights will shut off after they have overheated from their doors being left open.
God bless your day.

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.

Hi and welcome to FixYa, I am Kelly.

FYI... The door alarm will sound anytime the door is left open for more than 4 minutes.

Per your post... What it means your refrigerator is working normally.

However... there is the possibility of having excess ice build up on the evaporator coils from the door being open all night. If the freezer section starts warming up due to poor airflow you may have to do a manual defrost. You would first notice the lack of ice production or soft ice cream if there were air flow problems due to excess ice on the evaporator coils.

To do a manual defrost all you do is:
1. Unplug the unit
2. Remove freezer contents
3. Use a fan directed at the freezer compartment for just over 2 hours (makes a water mess)
4. Reload the freezer
5. Plug in the refrigerator

Everything should be back to normal in just over 4 hours except ice production that can take up to 8 hours.

Thanks for choosing FixYa,
Kelly

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?

Hi,

if the compressor is running your ref. should be getting cold. Their is a defrost timer but when it is in defrost the compressor shuts off. I think you do have a leak.

thanks,

i have just fixed my fridge freezer by following the instruction from KarenBa and GWoman i have also managed to stop the lights (super cool and super freeze) from flashing by turning the temperature to zero on both fridge and freezer so they turn off then holding both super buttons down for about 15 seconds then turning the temperature back up. hope this helps

Solution #2 did the trick for me...fingers crossed!
