My name is Peter. I am a retired field service refrigeration technician.
You are locked in the defrost mode. About every 8-10 hours your freezer will go into a defrost mode for 20-30 minutes. This is where all of the components will shut down except for the light.
You have water on the floor because your condenser fan and compressor is shut down.
You did not provide a model number. Your model number is on the inside wall of your freezer near the top. So, I can only guess.
Lets take your freezer out of the defrost mode. In the lower back on the left hand side is your defrost timer (This may also be in the lower front depending on the model). Following is a picture of what a defrost timer looks like.
The time is mounted on the back of a plate and held on with two screws. The plate has a hole through it to give you access to the round knob on the left. The knob has a slot in it. With a flat head screw driver turn the knob clockwise. You will hear a click. Turn one click at a time until the freezer turns on.
The timer cost about $20.00. You can replace it yourself. Unplug the freezer. Unscrew the timer. Remove the connector on the right.
You need to replace the timer or you will have icing problems.
Send me your model number and I will tell you what the part number is.
