The drain trough keeps icing up inside the fridge .
It starts to ice up after being defrosted. Door seals are ok. Soon gets to the size of a fist.The drain is clear.
Why dose this happen and what can be done to stop it ?
If there's ice in the drain trough it will be ice formed from water - if there's water in the drain trough then it's not draining out - clearly the drain hole is blocked. Poke some curtain wire down the hole.
