I need to replace the evaporator in my Kitchenaid

The blower is poor or somethin restrictd from the evaporator in the freezer area. Also u may need the compressor..or condensor testd. On an old fridge its cheaper to just buy a good used..cause parts n labor

Try this web page link and search on your model which did come up.
I went to the ice dispenser page 12 ... and it did have a door but not the same part number you listed. It was actually listed as a Whirlpool part with a different number AP6005973. Kitchenaid is owned by Whirlpool. But they did have a video on how to replace that particular door. Hopefully this is the door you need...

IT usually unlatches at the back and then you just have to puull it out the front.

The problem is most likely either the defrost timer, and/or the defrost heater element(s) are faulty. The problem is that the defrost heater elements are not functioning properly and the evaporator core is actually freezing up and blocking the air flow through the evaporator core and also freezing up the thermal sensor, and when that happens there is no longer enough cold air being circulated through the refrigerator (that is actually how the unit operates and air must be able to flow through the evaporator core and then be circulated throughout the refrigerator to properly function) and as a result the refrigerator stops functioning and food can even thaw out in the freezer although the freezer seems to be iced up. (Usually at the rear wall where the evaporator core is located)

(Air flow through the evaporator core and cold air circulation and re-circulation through the refrigerator is performed by the air circulation fan and it also must be functioning)

Be sure to only use a blow dryer (with a towel on the bottom of the freezer) to thaw out the evaporator core and do not use any hard or sharp objects or the evaporator core can be damaged. The defrost timer can be located inside of the refrigerator itself, (see lower image) or it can be mounted outside usually either behind the air intake cowl or kick panel at the front base of the refrigerator, or most likely located behind the service panel on the rear of the refrigerator, and usually if the defrost timer is turning then it is most likely working, however the defrost timer can move very slowly and you can place a mark on the timer and the housing to check after about fifteen minutes to see if the position on the defrost timer has changed. The deforst timer on newer digital models can be built into the circuit board and is not a seperate timer mechanism.

Here are some images that should be similar to your situation to help assist you and the operation principal is the same for either an over-under, or a side by side refrigerator, and let me know if you require any further assistance.

Hello and Welcome to FixYa!
Actually the leaking water is from the evaporator coil unit....(it is located at the back wall or underneath the freezer compartment). Under normal conditions,Self-defrost refrigerators usually dispose the water generated during the defrost cycle through a tube or channel that directs the water a pan (Known as Drip pan), commonly below the refrigerator unit....
The channel or tube is clogged and the water is leaking to the refrigerator unit, so you need to clear that blockage/contamination....Once the blockage is removed, the generated water will move through that channel/tube directly to the drip pan and there will no water on the floor in the refrigerator compartment. This is all you need to do....


Best of Luck,


Your token of appreciation in form of rating would be highly obliged,


Concerned.

is the compressor running too? if not, the relay is stuck.

Assuming that this is a self-defrosting freezer (which almost all are today), the defrosting coil or the timer may be bad. The defrosting coil actually warms up the freezer slightly every X hours. This thaws the ice that starts to form in the freezer. The vapor is then evaporated and exists out through a drip tube to the bottom of the freezer/fridge into a pan. The pan usually has the compressor fan blowing over it to evaporate the contents.

JOEHUNT TRY THE WATER VALVE ON THE BACK OF THE REFRIG BEHIND PANEL MAKE THE ICE MAKER GO THROU A HARVEST OR JUST WAIT TO HEAR IF IT GOES THOU A HARVEST THEN YOU CAN SEE IF (1) YOUR ICE MAKER IS ACTUALLY WORKING OR YOU NEED A WATER INLET VALVE ITS 1 OF THE 2 MOST LIKELY THE VALVE
