my fridge is not working.
It is a FFA90 fridge frezer the frezer is working but the fridge is not.
The compresser seems to be working when you open and close the door.
Yes there is a build up of ice on the back wall of the frezer compartment.
Just emptying the frezzer out before I start to look at it and noticeed there is a lot of ice on the bottem of the frezer compartment. Have taken the panels of the rear and have found the drain area at the back is frozen solid. Would this have an effect on the fridge not working? What is the best way of making sure this drain is working once everything has defrosted could I use a pin or something to open the hole up.
Hello, if the drain pan is frozen, it could have an effect if the ice builds up too much that it would block the return cavity that could be at the bottom of the evaporator coil. If the ice would block this hole, then the air returning from the fridge could not pass through and would have an effect on the cooling of the fridge.
If the whole evaporator coil is also blocked with ice, then the air that goes to the fridge is also blocked, hence, the fridge would not cool as well. What you can do is defrost the whole freezer and plug it back after defrosting and observe the unit again.
In some models, if the heating element is at the lower portion of the evaporator, you can put a piece of copper wire, loop it to the heating element and cut it with the end tip just inside the drain hole. What would happen is , if the heater would come on, heat from the heater would travel to the wire towards the hole by conduction. The wire should be of a thick gauge. so that a lot of heat can travel to the hole. This would make sure that the hole is also heated up when ever the unit is defrosting.
If still, after a few days, the freezer evaporator coil would accumulate frost, then I can say you really have a defrost issue.
BTW, to properly clear the drain hole with ice, you can pour hot water on it until you notice that water is now flowing at the back of the unit where it should.
Thankyou for your help.
Hi there again have finally got round to defrosting the fridge frezer. I have left the cover of the back and have pluged it back in the cooling and the defrost cycle seem to be working but I have not seen the fan working. Should this be working all the time or does it come on, on a cycle as well.
Thank you for that It looks touch wood that everything is working ok at the moment. Will run tomorrow before I comit to filling it back up.
Thanks for your help.
