Question:

Can a problem in the circuit board cause a no defrost issue?

Ernest for model number 10671209100
Answer:

Hello Ernest, that is a great question. Yes, the adaptive defrost control board PS11740238 could cause the issue, but before that I would test the defrost thermostat PS11742474 and the defrost heater PS11740357 as they can cause the same issues. These parts can be tested with a multi-meter. Hope this helps!

We were getting ice forming in the freezer compartment and water in the frig compartment

A. remove food from freezer and store in cooler etc.
B. turn off frig with dial in main compartment, then pull frig out away from wall and unplug and remove the cover ( It is located at the bottom of the frig and may be cardboard and contains a handfull of 1/4" screws) exposing the compressor and drain tube (this is a good time to vacume the compressor and coil area)
c. Take false back off from freezer by removing two 1/4 inch screws.
Next,
1. we made sure that the drain tube that runs down to a drain pan near the evaporator coil was clear, we did this by using a small aount of rock salt to speed up the melting of the ice then poured small amounts of hot water (boiling into the drain hole and soon the water flowed down the tube and into the pan below.
2. We then pushed a #12 standed electrical wire (with its end stripped back 1-1/2" then folding the strands back to create a broom) down the tube to the pan to push out any debree that may be present i.e. tin foil plastic bag particles, food chunks etc.
Making sure that this drain tube is clear is the first thing that could be causing the ice build up and water in the lower compartment!
However, I performed this several times and didn't change the problem so I chose to change the parts associated with defrost:
1. defrost heater, which is very easy to change. it is mostly plug and play but does require a pair of needle nose pliers to open a couple of metal fins to remove heater from its mounts, just be gentle with the process.

2. defrost thermostat, which is also very easy to change (Simply pull it off of a copper tube) but requires you to cut two wires near the old part and wire nut the new part wires to the remaining original wires, I added some anti oxident to the wires inside the wire nut to prevent a bad connection from developing do to moisture in this area (You can buy wire nuts with this already inside them, do this)and I taped the wire nut with a few inches of ELECTRICAL TAPE CLOSING OFF THE OPENING OF THE WIRE NUT.
You can then put his cabinet back together!
3. I also decided to change the defrost timer which is located inside a cover where the frig temperture setting dial is located. It is held to this cover by two phillips screws the cover is held in place by one 1/4" screw.
once you have the cover off and the defrost timer unscrewed you must remove a plug from the timer!
Now if you got the exact part you simply reinstall the defrost timer plug in the same postion on the new timer and screw the timer back onto its mount etc. However you may need to determine if the new timer is in the "DEFROST" position and you will need to take it out of that position by I assume rotating the timer mechanism (Ask a tech person about this)!!!!!!!!!
Then with all that done plug your frig vack in reposition it turn it on and be proud of yourself.

Now, if you recieved the timer I did it may look the same as the old one, but it may contain a black wire!!!
You will need to know which type of defrost timer application you frig uses:
1. Continuous run
2. version 1 Cumulative compressor run.
or
3. version 2 Cumulative compressor run.
I found a wiring diagram folded up and stored in the grill in the bottom of the front of the frig that helped me determine this. you will need to be able to read a wiring diagram but I found this situation to be simply a matter of matching examples of pictures (line diagrams). It is important though as you must determine which timer application your frig has because the black wire must be placed on a certain terminal for proper operation.

I replaced a three parts and may have, through trouble shooting, been able to save some money by not replacing all these parts. However , I found that when I went for guidance on trouble shooting that i.e. with the heater that ohmic values of the old part may be near the new part that it may still not be conclusive!? so for a hundred bucks my frig may last 5-10
