Is the evaporator fan motor running? If it is only running at half speed or not at all, that could explain the ice buildup. If the coils are icing up because of no air flow over them, then the defrost heater stays on, trying to get rid of the ice.

Are you referring to the compressor not shutting off down below or the evaporator fan inside the cooling area not shutting off? Evaporator fan always runs the compressor is controlled by the thermostat you could have a bad thermostat if the compressor never shuts off.

Water leak and noise are due to wrong temp setting or malfunction of defrost cycking.Keep temp setting between 3 and 5 degree centigrade. Due to over frosting, the freezer fan fan hits over the ice and working to cool fridge compartment.And also check defrost timer, and heaterworking properly to defrost in time. And if your ice maker is making sound, due to:

• You will hear a buzzing sound when the water valve opens to fill the water reservoir for each cycle.
• Rattling noises may come from the flow of the refrigerant or water line. Items stored on top of the ice maker can also make noises.
• The high-efficiency compressor may make a pulsating or high-pitched sound.
• Water running over the evaporator plate may make a splashing sound.
• Water running from the evaporator plate to the water reservoir may make a splashing sound.
• As each cycle ends, you may hear a gurgling sound due to the refrigerant flowing in your ice maker.
• You may hear air being forced over the condenser by the condenser fan.
• During the harvest cycle, you may hear a "thud" when the ice sheet slides from the evaporator onto the cutter grid.
• When you first start the ice maker, you may hear water running continuously. The ice maker is programmed to run a rinse cycle before it begins to make ice.

Hope, it's helpful>

probably an wrong freon level. Check that out. could be a freon leak from when the compressor was replaced. Bad weld joint could be the issue.
Let me know if I can be of any further help,.

Inside the cooler is the evaporator fan usually right in the middle behind a cover. As it slows down you have less circulation and ice forms quicker and cooling is diminished. Sounds like it is going out.

Is it getting cold enough to cycle off. Should be around 10 degrees in the freezer.If the evaporator coils behind the back panel of the freezer are icing up because of auto defrost failure that will gradually cause it to warm up because ot the blocked air flow.

SOUNDS LIKE U MAY HAVE A BAD DEFROST TIMER, CAUSING THE COIL TO ICE UP, AN SINCE THE COIL ICES UP THERE IS NO AIR PASSING TRU TO KEEP THE FREEZER COLD AN THE FRIDGE COOLER, THE FAN MAY BE WORKING BUT IS NOT MOVING ANY AIRE TRU IT, BECAUSE THE BLOCKEAGE

More than likely you need a new compressor. It sounds like it's trying to start and then trips on it's "Klixon" overload. Call a commercial refer guy (not somebodys brother in law that works on A/C, it's NOT the same!)
