Hisense upright freezer has alarm lightvon all food is thawed out.

If the control is "ON" and the compressor is not running, you will need a start relay... Make sure you didn't accidentally turn it off by pushing food against the control knob!

That alarm light means that the unit was too warm for a period of time. The door may not have closed properly. It is a warning to you that the food may have thawed out. It does not mean something is wrong. To reset it switch it off and on or unplug it for a minute.

freezer isn't working; do you hear the compressor kick on? No? then it has to be serviced

Check the door sits straight and square on the front. You can "adjust" with the heel of your hand to make it sit flat against the frame. Even a poor seal shouldn't make frozen food thaw - check and clean the condenser and fan

i would make sure that the coils are all clean, inside and out. make sure the fan runs on the back, the water pan isn't over flowing.

my father was a cook
anf he lived by one rule of food

when in doubt thrwo it out

a leaking gasket can cause food to thaw and it can be fixed if a new gasket is avaliable from local appliance parts place..the gasket is held on by the liner which is removed by gently lifting the gasket and removing the screws..the reverse to install the new gasket

The beeping and light indicates the need for a new battery (9v)

The red light and the audible alarm both come on when the freezer gets warmer than the alarm point... unless you disable the audible alarm with the rocker switch

check your defrost timer
