A6K32E7C part number for kit to keep water from blowing out thru the evaporator

Yes, you have a blend door that switches from the A/C evaporator core over to the heater core. If this door is not moving, you will not get the chilled air passing over the evaporator. You will also have another blend door that switches from fresh air intake to pulling air thru the airbox and across the evap/ heater cores. Either of these could be your culprit.

The pan in the inside of the unit or the one underneath for collecting and evaporating the water?
If it's the one inside take the front bottom panel off and blow out the drain line leading down there. If its the pan underneath and it cant keep up with the water flow check to be sure it has some white cotton looking panels in the pan. They are an accessory called a wicking kit designed to absorb the water and as the air blows over them they help evaporate the water. If those are present and in good shape but its overflowing there you may need to get an electric condensate pan.

Your model number on the body of the freezer will have that. You can also get size of comp. and fan and rotation located on the pieces itself.

if the rear wall inside the freezer has ice build-up on it then the defrost isnt working,remove this panel and check evaporator coil if its iced up the evaporator fan cant blow the cold air thru this coil,defrost it with a hand held hair dryer,then check the heating element located below the evaporator coil for continuity then check the round defrost thermostat on the top of the evaporator coil,note,this part needs to be tested below 32degrees to test good above that temp it will show open or bad

Water in the drain overflowing can be the reason for the water spilling,it can be the defrost overflow or the leak from the evaporator tubing's to the drain. So drain off and check perhaps more condensation is the result of the overflow.
The icing can be related to water formation from the food or leak from the evaporator, high frosting can blow the water inside the freezer.
So set the freezer temp a little lower so that the freezer shuts off than to make it run continuously.

Make sure the coils are not dirty,if they are not dirty,add freon to the system,not much,feel the evaporator,when the evaporator is cool all over,and the condenser is warm all over,there is enough freon,add very little at a time,this system does not hold much freon,if this was helpful,at all,please rate,thank you.

What in blazes is a " wet wall evaporator " ?
Remove the food and the ice maker from the freezer ( if equiped ) . Remove the rear freezer panel . Using a hair dryer , start in the middle , below the coils , defrosting , until you see the drain hole . Use hot water to help defrost the hole . Once water starts going thru the hole , use a small hose inserted into the hole , and blow thru , to remove any unseen debris in the drain line . Use an ALUMINUM or COPPER solid wire , 14-16 guage , with the insulation completely off , and insert one end into the drain hole as far as possible without any force . Wrap the other end about 1 1/2 to 2 turns , around the black rod (defrost heater) , above the hole . When refrig goes into defrost , the heat will transfer from the heater , to the wire , keeping the hole from freezing up again .

You always need to keep both coils clean on your AC.

The evaporator coil (where room air is drawn in and through a filter) - is easy to keep clean - 'just keep the filter changed on a regular basis and you will probably never need to actually clean the evaporator coil. Occasionaly you might need to brush the coil with a brush or something - but this is not a big concern.

The condenser coil (where hot air blows from) is even 'easier,' for you don't have to mess with a filter, just keep the coil clean. You can occasionally pull the unit (when needed) and wash this coil with a water hose. In reality this coil will not get very dirty very fast - although it will (over time) acquire some dirt/dust, but as I say - it is pretty easy to keep clean. Note: Condensing units (split systems) that sit in a yard will get much dirtier much faster than window/thru the wall units such as yours, but you still have to keep a eye on the coil.

A good rule of thumb - is to change the filter (in front of the evaporator coil) - monthly.

As for the condenser coil (where hot air blows from) you can easy see it and just need to keep it clean, with no set (usually) time to do so.

good luck!

There is no "standard" amount of water that will be used.

This is a flow-thru type humidifier, which means water runs through an evaporative pad and air blows over it to evaporate the water and humidify the house.

The amount of water the unit uses will depend on the house water pressure, humidistat setting, outdoor conditions, the condition of the humidifier pad, the temperature of the air flowing over the pad, the size of the house, the number of people in the house, the amount of of moisture-absorbing material in the home like textiles, carpeting, drapes, furniture etc., and temperature in the house. There are other factors as well.

The humidistat should be set to the lowest point possible and still provide some humidification (so you don't get zapped by touching metal objects or light switches). Some stats are calibrated in percent, while others simply have numbers on the dial. If you have the stat set too high, you may see frost forming on windows or around doors, in which case the setting should be lowered.

Use an ALUMINUM or COPPER solid wire , 14-16 guage , with the insulation completely off , and insert one end into the drain hole as far as possible without any force . Hook the other end over the glass rod (defrost heater) carefully , so not to break the glass , above the hole . When refrig goes into defrost , the heat will transfer from the heater , to the wire , keeping the hole from freezing up again .
