Lec freezer if i turn thr temperature up the red light starts to flash

More than likely as long as a day

A flashing red light on a tall freezer indicates that the appliance has detected a temperature alarm, and the temperature inside the freezer has likely dropped below the desired range. A temperature of -6 degrees Celsius is much lower than the recommended temperature for a freezer (-18 degrees Celsius), which can cause frozen food to become damaged or spoiled.
To resolve the issue, you should first check the freezer's manual for troubleshooting tips and recommended actions. In general, you may need to adjust the thermostat to a higher temperature, remove any obstructions to airflow, or defrost the freezer if ice buildup is blocking the evaporator coils. If the issue persists, you should contact a qualified technician to diagnose and repair the freezer.

Seems like the compressor on the freezer stopped working

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 Morning Friend, thank you for allowing me to assist you!

Did your freezer previously experience a power loss? If the temperature of food rises to an unsafe level, the buzzer will sound and the red light, if equipped, will also glow. First, deactivate the alarm to your freezer by unplugging it or flipping the household circuit breaker. It is good to wait approximately ten minutes and then turn on your freezer. After deactivating the alarm and your freezer has run approximately four hours, the red light/alarm should go off on its own. If the red light/alarm continues to stay on, your freezer may possibly have a communication problem with the control board, temperature control or a wiring harness. If this is the case, I would recommend connecting with an experienced technician to determine the underlying cause. - Z

Under normal operating conditions, the internal
temperature of the freezer will ensure the longterm
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.

This will happen until the temperature gets down to an acceptable temperature.

3 star freezers are not storage freezers and will maintain frozen food for a short time only, They should reach -18c when closed but may come up in temperature quite rapidly when the door is opened. They are usually found as the cooling evaporator in fridges with freezer boxes in. Four star freezers are dedicated freezer storage space and will keep frozen food at the right temperature for some months.

you have more than likely ruined the control board on the refrige,a dryer and refrigerator should each be on their own dedicated circuit,they use an enormous amount of current to start, and even if one is running and the other starts thats enough to trip even a 30 amp receptacle, and furthermore extension cord use on these types of appliances even a large gauge cord i.e. 12 ga. that will carry 20 amps is not even a good idea because of voltage drop,as this causes motors to draw excessive current and over heat the motors and reduce appliance efficiency too

It may be that the temperature of the unit is not yet up to temp.The flashing light will indicate this.Warning the user the unit is not ready,or up to safe temp.. Let the unit run to catch up,since you just started it.
