The model is CDA 660f and it is frost-free, 2 yrs old. Fan is working but not effective in freezer. When we first had it, it was very noisy when freezing. Now it is less noisy - not sure if thats good or bad!
When I increase setting on the thermostat, sometimes the motor kicks in, sometimes it doesn't, even tho the fridge and freezer are clearly not that cold.
What is pcb?
thanks for your help
