model no. atraight from the unit is GSS25SGMC BS --
I think I forgot the C in the original post, not sure if that led you awry, sorry.
here's the main scoop: I'm starting to think that this is all starting (and happening) because of the water freezing up in the icemaker inlet tube, becasue it must also be leaking water down the back of the freezer section which can't help but cause a defrost problem. Am I right on this, if this is what is happening?. I don't know well enough how these things work.
My heater element is good, i have a brand new defrost thermostat (which was not working/opened up so not sure what was the cause of that), so I understand my next steps would be to replace the thermistor on the top of the evaporator, and if that doesnt solve it, then it must be my board.
Before I start all that, however, I really think the problem may be simply coming from water weeping through the water inlet for the icemaker. (The water in the door works fine by the way.) The only problem I have had with this fridge over the past 10 years is the crushed ice auger not being able to work because ice seems to accumulate in the bottom of my ice cube bin/tray. Again, I think this might be a hint that this problem is just worsening but I don't know enough about it.
I think it might be wise to start looking into the water inlet before I start buying and changing more parts, and look to you for your advice on this.
How do I check the water inlet valve? Is it going to be under the fridge in the back? Do I need to check anything with the actual inlet hose in the back of the freezer which ices up every once in a while -- but not too often, maybe once every 3-6 weeks-ish.
This whole problem started when I started getting puddles of water from the freezer, and then the fridge section wouldn't be cooling.
Also, my freezer fan is constantly running and I am iced up again.
