Fridge Icing Up

[LadyDTM]

My fridge ices up so quickly, I mean thick ice within a few days on the back wall. I have cleaned out the drain, so don't know what else I can try. I have noticed a couple of cracks on the walls so maybe this is contributing? It is old but is working ok, its just the icing up is getting worse. Thanks in advance

Could be that the door seal is knackered, LadyDTM.

either door seals or thermostat.

If it's the door seal they are pretty easy to replace.

Does your fridge have a freezer compartment. Is it’s door sealing properly? If not it can make the fridge part ice up.

Edit. Check the freezer part isn’t iced up itself. It may appear to shut fully but excess ice could stop it sealing properly

Before you buy a new seal just have a look at the bottom of the door. They often corrode and make a seal impossible

this happened on my fridge freezer. I never knew but the cold air in the fridge comes from the freezer, there is a vent in the back with a sensor and a valve. Over time the sensor and valve will freeze and the valve will either stick open or shut so you either get too much cold air or not enough. All you need to do is empty your freezer and remove the back panel. You will see where it has frozen and all you do is boil a kettle and let the steam melt the ice.

Thankyou all for your answers. My fridge and freezer are combined and also an integral appliance. I will have to try and take the doors off to remove it to get to the back as suggested. Wish me luck :)

Quick way to defrost is to put a fan blowing on freezer compartment
