Hi,my fridge freezer is a whirlpool 20RB-D3J model no:8586 4411 5010 . Its only 15 months old and has the chattering relays problem . The chattering was coming from the pcb board situated in the lower right rear corner{looking towards the back of the machine} I took the rear pcb off and replaced with a complete new board at a cost of £110 bought from UK whitegoods part no 480132100476 – Whirlpool Rear Control PCB .I defrosted the FF completely by removing the white rear plastic covering the heat exchanger ect from inside the freezer which was frozen right up. It worked fine for about 1 day and now the chattering has come back .The display seems fine and it is cooling correctly at the moment [freezer -17/fridge 6] but it seems to be working harder as the days go by.It has now been clicking for 1 week and i assume it is freezing itself back up. Could the new part also be faulty as they are obviously a poor quality part or is there another part to change. Does anyone know what to try next.
Thanks in advance
Chances are , the board was damaged by either a faulty water inlet valve or a faulty ice dispensing solenoid , both known issues on these later units , and has probably blown the board again if this hasn’t been rectified
Thanks for your help . Are these parts part of the front pcb board on the front door or are they different parts entirely,where can i find them . You think i have blown my new board already,Sh*t. Thankyou in advance
If either or both of these parts are shorted , then it probably has blown the board ; You need a suitable test meter to check them though ….
1 is in the back adjacent to the rear board , the other inside the freezer behind the ice cube storage bucket at the back
