On my whirlpool S20 BRWW20 fridge freezer when I switch the icemaker on there is a clicking coming from the relays on the control PCB. Is this a faulty PCB.
Yep, it is probably going to be a faulty pcb, either the back one, the front one or both. I need the model and serial numbers to be more precise.
Can you post the numbers that are on the label next to the vegetable bin, there should be 2 rows of numbers 12 digits long starting with 85*****
