i bought this bosch KGN33V00GB fridge freezer in september 06. it has always been quite noisy, after 13 months it started to frost up on the metal fins in the top of the freezer, and the fridge compartment started to get warm, resulting in a lot of wasted steaks
so i looked around the back and the tray at the bottom was full with water, i emptied the tray and gave the freezer fins a full defrost. i also took the air flow panel off the inside of fridge compartment and replaced it in the fully open position.
recently the cold freezer / warm fridge has returned.
from what ive read in the forums here the cause may be
1) a drain pipe blocked with ice with a fix part available
2) a sticking fan
3) a thermostat problem with a fix available by soldering a short on the pcb (tho not sure if this affects my model)
can anyone help me narrow down the problem further and point me to where i can buy the repair parts if applicable.
