HELP needed for …Whirlpool S20B RSB21-A/G..

[Rebels-59]

Hi,, I am NEW here but have read some other topics and think several of you may have the answer for me…

Last week i cleaned out the Ice Cube Container as the Cubes were stuck together Slightly.. Since then, The Freezer Runs Perfect for a hour and then the Alarm goes Off, The -18 on the Door goes to – -.. If i turn the Freezer Off and Reset it, It runs great for another hour and Alarm goes Off again.. I also noticed the Fan isConstantly running and Never goes off..
So for the past few days , I cancelled the alarm only to stop the bleep and have just left it, As the freezer appeared to still work , Although not sure on the Ice Cube maker…
Anyway came home tonight and it Seems the Fridge although set on 3 is NOT Cool.. it isn,t Hot but clearly isn,t working..

ARE ALL these symptoms down to the Same problem and is it a easy Fix.. The Fridge Freezer is only 4 years old, And i have just about lost All patience with it..

OK, THAT WAS A MESSAGE from Last Week on Another Forum..
UPDATE
OK, Looking into getting a New PC Board for the Rear.. BUT today i was checking on the Web and there was a Guy with the Exact Same Problem as Me.. He changed ALL the Caps on the Rear PCB and the Problem was the Same,, So he emptied the Freezer and took the Inner Rear Panels Off and found a Massive Ice Block covering everything, So he Defrosted it with a Hairdryer and he said it now works Perfect..
Anyway i followed his Advice and removed the Inner panels and also mine was also solid ice,, I have now Defrosted everything and switched everything back on.. I can feel some Cool Air now coming into the Fridge , But it has only been running 2 hrs MAX..
Would the Rear PCB cause Ice UP.. Or is it cause the Kids leave the door open too long.. Will update tomorrow to say how it is performing.. BUT the Alarm is staying Off on the Freezer now..

This worked Great for 1 Week.. But last night the Alarm went off again, So tonight i removed the Back again and Defrosted it Again with a Hairdryer,, Again it is Now working Perfect Again…

So is it the Rear PCB i NEED… PLEASE HELP and Respond As Soon As Possible

The only way to be sure is to replace the board although you may be better to also replace the freezer sensor block thingy, I forget what they call it.

It sounds as if it’s not entering into a defrost or, not correctly at least.

Can you give us the 12NC number to look it up?
