Freezer and refrigerator both stopped cooling. I noticed frost buildup was apparent through the vent at bottom front of the freezer compartment , so I disconnected power for two weeks to ensure a thorough defrost. Once water seemed to stop draining to the floor, I reconnected the power, and the cooling seemed to resume normally. However, there is now an intermittent knocking sound that seems to occur when the fan is running. I'm wondering what moving part is making this noise and needs to be replaced.. Could it be the fan or fan motor failing that caused the frost buildup, or is there some other likely component failure?.
You have a defrost issue which need to be dealt with. the fans is hitting the ice that has formed after 5 to 10 days of not going through a proper defrost phase, you either have a bad defrost controller, def t-stat, or def heater. and can easily id the issue

What is the procedure to trouble shoot and determine which component is the bad one? Is there special diagnostic equipment or expertise necessary, or can I determine the culprit myself without blindly replacing all of the potentially defective parts?
1st do you have a multimeter and more importantly do you know how to use it... if so you will need to ohm out the Def heater and Def tstat audible ohms is easiest if equiped with digital meter (Note the def tstat is only in a closed loop at or below 30*f otherwise will read infinite or open). If those two components test fine replace the Def control ( def timer or main control board)

You are probably correct that it is the evap motor. If you are seeing frost on the back wall then there is probably some ice built up around the motor and the fan blade is hitting it.
Try defrosting the freezer and look very closely all around the seal for the freezer drawer. It is common for moisture to freeze in the self closers in the drawer rails and not let the drawer close completely on one side or the other. If this happens the small gap will allow the freezer to frost excessively.
Sorrry to be slow in responding. I have been very busy this week and have not been on line very much.

you need a drain tube heater.it is like a chain fence tie made from alluminum,you can actually use the fence ties,wrap one side around defrost heater and stick the other side in drain.that will prevent it from happening again

Loss of coldness is common with compressor related problems....relay and overload(simple fix), loss/leak of refridgerant(need a cert. tech). need to check the compressor and see if its running....do this by pulling the unit out and removing the back panel, place your hand on the compressor and see if it feels like its running....if not probably just a relay, if it is running, could be a more serious problem dealing with sealed system.

Is the compressor coming on at all? If not a capacitor may be bad .

That model refrigerator uses the mother control board for deciding when defrost is to take place. It has no defrost timer or Adaptive Defrost Control like other refrigerators. This sounds like *********** board part number WR55X10942 is malfunctioning. The board decides most functions of your refrigerator. Until the board is replace I do not believe the problem will resolve itself. Thanks, Sea Breeze

The available assembly schematic is not very helpful to a novice trying to disassemble the freezer interior, without breaking anything, to get acess and view suspect components. A technician deterined that the defrost heater and defrost thermostat checked out okay. The defrost controller, a simple plugin component a.k.a. defrost timer, was determined to be the defective component.. I replaced the defective defrost controller, which apparently had been causing the noise that sounded like it could be ice buildup interfering with the evaporator fan. The fan was not the problem. The defrost controller was apparently stuck, causing the noise and the failure to periodically defrost.
