Bosch Fridge Freezer iced up

[a4turbos]

Hi All,

Hope you can help with my Bosch Fridge Freezer which should be frost free.

It is a KGN34X60 model bought about 2-3 years ago. about 6 months ago the freezer unit started getting iced up at the top and you could see the plastic at the back and top swelling from ice behind it. I took the freezer apart and the ice was solid all around the top and back. It took about a day to get it fully thawed out.

With that done it has ran fine up until now and it looks like the same thing has happened again.

Any suggestions as to what could be faulty? Heating element? Temp sensors etc..?

cheers
Steve

As you suggested... temp sensor, thermostat, defrost element, defrost timer, eveporator fan.
