I have a three years old fridge without "no-frost" or anything similar to avoid ice build up. Yet there's a fan in the main compartment - about 90 millimeters in diameter and running simultaneously with the fridge compressor. The salesperson couldn't explain why it is needed.

Now that fan started to produce knocking noise which made my almost silent fridge rather noisy. I detached the fan cover, found a neat connector and unplugged the fan and the noise went away.

Now I have two options - either I fix/replace the fan or just leave it disconnected (or maybe remove it).

Do I really need that fan for the fridge operation or is it just useless and can be left out?

I would assume that the manufacturers put the fan there for a reason. What does the handbook (assuming you have one) say about the fan? –  ChrisF Jul 25 '12 at 8:28
    
@ChrisF: It says nothing about the fan - just something like "thank you for choosing our fridge". –  sharptooth Jul 25 '12 at 8:36
    
It stirs the air so the compartment stays evenly cool. Otherwise cold air drops down to the bottom and some things can freeze. If you can deal with that, no it isn't needed. –  Fiasco Labs Jun 17 '13 at 15:13

Well, ten months have passed and I see no problems with the fan disconnected. Which is no wonder - I've seen many fridges with the same design that had no fan and they worked fine and this fridge also works fine without a fan. The new fan costs like one tenth the price of a new fridge, so just having the fan disconnected is a no-brainer.

To anyone who reads this I have to remind that the fridge in question doesn't have "no-frost" or similar things which might require the fan. If you fridge contains "no-frost" this answer may be completely inapplicable to your fridge.

Good update - I let the fan go out in mine and... no change after 2 years. People always assume that spending money makes things better. –  DMoore Jun 17 '13 at 17:45

It is a pretty strange design to have that fan inside the fridge. But it is needed to circulate the cold air properly within the compartments it self.. it helps avoid mould growth, humidity build up and other horrible things.

-- Fans go out sooner or later.. but they usually start to make horrible noises after 12 months.. I would suggest finding a replacement.. and order 2 or 3 because it will do it after 2-3 years again. That is just how it is

--You could try and source the same dimension fan and voltage from another supplier that is more expensive.. because they put real bearings in that should last 10 years... but it will be a mission.

I am sorry that there is no other real alternative unless you start to go into real DIY and start rearrange everything in the fridge.

You almost certainly need it, manufacturer cut costs everywhere they can, they wouldn't put an electrical device in if they didn't need to. The cheaper fridges I've had over the years share the cold between the freezer and fridge and had fans or blowers setup to move cold from the freezer into the fridge area. If you post the brand and model numbers you can find, someone here can probably point you to a direct replacement.

I think the model you have is bit old and what it dose it. Just cool the deep-freezer and pull the cooled air to second compartment. So if you remove it your normal cooling area will be less cooler.
