Freezer has layer of frost on back wall - refrigerator not working

Ice build on the freezer box floor or White frost build up on the freezer box back wall (inside). Ice layer on floor means your drain line blocked. White frost layer means your machine is not going into defrost cycle.

This is one of the first signs that the refrigerator is missing defrost. Open freezer door and look at the back wall of your freezer. When a refrigerator does not defrost you will see a frost layer covering the rear panel back or bottom panel of your freezer. Below is a small photo of a refrigerator freezer that has not been defrosting. For a larger photo click=> HERE Thanks, Sea Breeze
Your BX50RE is sold in the UK? Think you may have one of three problems causing this and number one is the defrost heater two is the defrost control and last the defrost thermostat.Click to enlarge
By the way you will not see this in freezer because the rear panel covers this, but there should be a layer building on the outside of that panel.

open you freezer drawer, hold the light switch and see if the fans runs. if no fan you have either a bad control board or a bad fan motor. if you have a fan running check the back wall of the freezer for frost. if you have frost on the back wall you have a defrost problem. either way you may need to call for service. they can trouble shoot and replace the proper parts. if you use the process of elimination you will spend more in the end.

How to Defrost Refrigerator Defrost Timer Problem

I had a similar problem. The frost in the back is an indication that your coils are frozen. This could be from food packages falling out of the freezer drawers in the back and blocking the air circulation vents or maybe the freezer door was not closed completely and letting moist/humid air in and freezing the coils.
For me it was the first problem listed.I had to completely empty the freezer and Frig. and take the back panel off in the freezer. There you will see the coils and lots of ice!
1. Remove all items from the frig. and freezer and unplug frig.
2. Pull all the freezer drawers out.
3. On my GE side by side I took the light cover off and removed the bulb. There you will see two panel screws. Remove the screws.
4. Now pull out the mouldings on each side and you should be able to remove the panel.
5. Take a hair drier and completely defrost all the ice from the coils.
Be sure to keep plenty of towels handy for all the water mess. Remember to keep an eye on the drain tray in the back of the frig. and use a sponge to collect the water that will build up.
Hope this helps!.....

You probably need to defrost freezer - frozen moisture possibly stockedevap. fan motor in the freezer. Turn it OFF for 24 hours and start itover. Make sure no moisture condensation on the freezer compartmentsurfaces as walls and shelfs. If so wipe it out. Pull out and remove upper basket from the freezer, push fan switch which is located almost under ice maker.You have to hear evaporator fan motor start working. Still not work? Call to professionaltechie! Good luck! :)

DEPENDING HOW OLD THE UNIT IS YOU MIGHT HAVE A BREAK DOWN IN THE INSALLATION ON THE SIDE WALLS OF THE APPLIANCE.ALSO CHECK THAT THE DOOR SEALS ARE SEALING OK IF ITS A BREAKDOWN WITH THE INSALLATION THAT MIGHT BE A COSTLY REPAIR BUT GET A TECH TO GIVE ADVISE.GOODLUCK.MOHAMED

Hi Frezer Frost.
It sounds like your defrost circuit in the refrigerator has gone south. This melts the ice off of the cooling coil in the freezer section every 8 - 10 hours of run time.
If you are old enough to remember the manual defrost refrigerators, that is why you had to defrost them occasionally. The ice layer on the coil acts as an insulator, preventing the coil from working properly.

look on the back wall of the freezer is there snow? if so you have a defrost component out (timer, limit, or heater) the fresh food compartment gets cool air from the freezer so check for blocked air pathways the build up of frost in the freezer stops air flow so you will be cold on freezer side and warm on ref side

There's warm moist air entering the unit from the back somewhere. Pull the unit away from the wall and check behind there. Look closely at where the Ice Maker fill tube enters through the back. If you find the air leak, use "perma-gum" (google it) to seal it.... not silicone.
