Removed ice and it froze soon after. haven't changed the settings.
HI
The limit switch is found only on frost-free refrigerators and freezers. Its function is to keep the defrost heating element from exceeding certain set temperatures. If a refrigerator has lots of frost in the freezer compartment, the problem may be the limit switch.
OR
This component is a heating element located on the evaporator coil. When the refrigerator or freezer switches to the defrost cycle, the defrost heater is turned on to melt the frost in the compartment. Failure of the defrost heater causes failure to defrost.
Test the element with a VOM set to the RX1 scale. To gain access to the heating element, remove the compartment's wall panels. Clip one probe of the VOM to each element terminal. The meter should read between 5 and 20 ohms. If it doesn't, the heating element is faulty and should be replaced. Replace the heater with a new one of the same type and electrical rating. Connect the new heater the same way the old one was connected.
The drain ports are located along the bottom of both the freezer and the refrigerator sections of the unit. These holes can become clogged with debris or ice, causing a drainage problem when the unit is defrosting. To clear the ports, use a short section of wire that will fit the holes. Do not use a toothpick, because the wood may break off in the port and become stuck. On some refrigerators, the drain ports are located near the defrost heater at the evaporator coils. A lot of disassembly is required to clean this type of unit. If the refrigerator or freezer is this type, you may be better off calling a professional service person to clear the ports.
On some freezer compartments, the drain is located under the freezer compartment and shaped like a shoehorn. This type of drain can usually be unscrewed so that the drain area can be cleaned.
The condenser fan is located under the bottom of the refrigerator. During the defrosting cycle, water may run through a small hose into the drain pan and is naturally evaporated. On some refrigerators, the drain hose is rubber instead of metal. This type of hose can become cracked, causing leaks. Examine the hose. If it's damaged, replace it with a new one of the same type. If you spot water on the floor, the drain pan may be tipped on its brackets, or the pan may be cracked or rusted. To eliminate the leak, realign or replace the pan.

You MUST defrost entire freezer to unplug tube! the ice (frozen water)within the tube will be especially stubborn!
There is no much that you can do about this, defrost the fridge completely, and if the water lines keep freezing, lower down thermostat settings.
To make things in the right way, you need to buy a fridge thermometer, and read fridge internal temperature, that must be between 35 and 49.
If temp is close to 35, turn it up, if it is 39, lower it a bit.
Check also that the coild at the back of the fridge are not freezing, in that case there is a problem with the evaporator system.
Ensure the door gasket is sealing properly, and do not leave fridge door open for long intervals. If gasket is weared, deformed, or stiff, replace door gasket.
Another cause for this kind of problem may also be a faulty thermostat control, behaving erratically, but this is rather unfrequent.

Hi and welcome to FixYa,
Initially, have you tried changing/setting the freezer temperature?
Good luck and Thank you for using FixYa.
Hi again,
Appreciate the postback.
If it is cold in your location, then the ambient temperature is already low. It would take very little effort for the freezer to bring this further down. Assuming that the water temperature from the supply is barely above freezing, not much really that could be done.

adjusted setting down 24 hours ago just after posting problem. Can see icicle hanging from little black tube coming out of freezer ceiling.
