I have an ariston fridge, freezer on top model about 5(?) years old. Lately the fridge has stopped cooling properly but freezer is still warm. The fan etc was working fine but was noisy so i pulled the back off and the coils were all frosted up. I have defrosted it twice now with a hairdryer which fixes the problem for a few weeks but then the coils start to freeze up again and it needs to be repeated. It seems from reading that it is the defrost time/heater... Can anyone tell me where to find these in this type of fridge and how to check them. I couldnt see anything in the back but then maybe i dont know what im looking for.
Any help would be greatly appreciated so i dont break something in my search. Thankyou!

Re: Ariston Fridge not cooling - Frozen Coils
Try to check the noisy fan, slow rotation of fan can cause the icing evaporator. Unplug the unit and rotate the fan manually by your finger check if the fan is not misalign or not touching the fan frame. Or check if fan motor bearing is not worn out. Under charge of gas is also one of icing cause.

Hi, The noise is the fan hitting ice build up on the coils... it is no defrosting properly...
Check out these tips...they can help you figure out whats going wrong with yourrefrigerator and why it is not cooling
The defrost drain is located just under the cooling coils in the back of the freezer. You will need to unload the food and remove the shelves from the freezer. Take the back panel off from inside the freezer and you will see a hole just below the coils. Flush it with hot water using a turkey baster or small hose. See the link below for more details.
Have you pulled out the refrigerator and cleaned or used a vacum cleaner to get out the dirt and dust off the back of the coils, or if the coils are underneath, you need to get an inexpensive appliance brush for fridge, and clean the coils under the fridge, pull off the panel on the front bottom of the fridge, get a flash light and look to see if the coils are covered in dust....may just need to vacum and use appliance brush underneath...this should be done at least one a year, you will notice your fridge running much better and cooling back to normal.......hope this helps......
Your evaporator coils frost up in normal use
and every eight hours or so the entire unit shuts down and the defrost heater
comes on to melt the frost. This cycle last about 20 minutes. The melted frost
drips into a drain pan and through a drain tube to the drain tray under the
freezer/refrigerator where it's evaporated by the condenser fan.
Your drain tubemay be stopped up with ice at the upper end
because it drains too slow because it's stopped up at the lower end in the
evaporator pan under the unit at the floor. It can get dust and mold in it.
Once you get the ice out at the top a little pressure with a turkey basterwill usually clear it out. Flushing
it out with hot water and clorox may help. Make sure it drains quick enough to prevent
refreezing. . The drain should be located below the evaporator coils on the
lower back of the freezer.
on some fridge freezers there is a channel which is designed to take condensation from the fridge out through a small hole at the bottom of the back wall of the fridge check this hasnt got blocked or iced over, if the unit is a few years old it is possible that there has been some evaporation or leakage of the coolant mixture, that may be whats on your floor, the pump can therefore no longer pressurise the mixture sufficiently to cause it to remain cold,
