Probably a loose fan or ice hitting the fan, defrost freezer & check fan.

Make sure all the bulbs aren't bad. (it happens more than you'd think) If not try wiggling the light switch at the top of the unit. You can usually get the lights to at least flash. Take the top grill off and either unplug the unit or shut it off at the breaker. Take off the switch cover, remove the wires from the light switch. The light switch is all white, the fan switch has one black side. pop the switch down through the frame and then pop the new one up into the hole. Reattach wires and reinstall cover.

It is likely the condenser fan is not functioning or the condenser is plugged with dirt. You may need to open the compressor access panel to check. If you can hear the compressor running, and the condenser feels warm, the fan should be running. If it isn't, it probably needs to be replaced.

Is the fan running? Has the door been left open? That unit has an automatic defrost and if the coil doesn't get cleared of frost it won't circulate air.

The LCD is light up by the lights in the refrigerator, so that doesn't mean the board is turning on just the interior lights. I would have to recommend a service call.

Look at the back of the bucket and you will see a lip. Look inside the machine and there will be a white sheet metal rectangle that will roll forward. Pull it as out until it stops and then the lip on the bucket hangs on the top edge of the rectangle.

Hi,Replace the water inlet valve to the unit. The valve is not closing completely after the water is called for. By replacing the valve should solve this issue.I hope this helps. I’m happy to help further over the phone at https://www.6ya.com/expert/gere_bf68e6055dd61249

Hello FrankRemember that on older fridge and freezer units as well as many low-tech or older units you will find that they operate by way of a pretty simple device that is known as a thermostat. This is much like most thermostats in that it will generally, in any refrigerator or freezer at least, offer only two operating positions as it is, in effect, a simple mains switch, on and off.Best RegardsNeciforo Llanto

an "EE" code means you have an open thermistor. "EC" is a extended compressor run code. typically with the 424 if the thermistors are good, as in no "EE" codes you probably have a refrigerant leak. 73UE is the temperature at the upper evaporator thermistor. 73LE is the temp at the lower evaporator thermistor, 73up is the upper compartment temp and 73lo is the lower compartment temp. the unit probably has a leak in the evaporator/heat exchanger assemblies and needs a refrigeraton system rebuild

Go to page 75 in the service manual where it explains the drip pan for different models. Click HERE I will be here should you have questions, Thanks Sea Breeze

It is very common for this refrigerator to have a freon leak in the evaporator.Since you need a EPA license, This is usually beyond the scope for the home owner to repair.http://www.on-timeappliance.com/subzero.html
