Press and hold the Control Lock key for three seconds
to activate or deactivate the function. The Control Lock
feature prevents the user from changing the temperature
and freeze settings. At the first press of any key, the
key press click tone will be heard and the display will
show "LO", but no other change will take place. Holding
the Control Lock key for three seconds will activate or
deactivate the Control Lock feature. After three seconds,
the accept tone sounds and the Control Lock LED (if so
equipped) is activated. In lockout mode, when any key
is pressed, the invalid key tone will be heard and "LO"
will be displayed for 1 second. When the lockout is
deactivated, the Control Lock LED is turned off and the
display shows "UL"

if this does not work unplug the freezer for 30seconds then plug it in. if all of the above fails replace the control.

Parts should be sold at your nearest refrigerator parts supplier.

Sounds like the relay contacts are staying open.

The symptoms you describe are a locked compressor. A compressor replacement on a deep freezer is usually around $400.00

this could be from a faulty temp controller however my best! bet is it's low on froen due to a high pressure leak

you have a air lock in the compressor

upright or chest

leave it a half day in its operating position before powering up

It freezes up because there's warm air going through the door or the gaskets are letting the outside air getting in.
