Our freezer is not de-frosting, there is a build up of ice

A frost free fridge or freezer has a heating panel that is switched on for a short time at the end of each cooling cycle to melt any frost that has formed over the evaporator.
The resulting water droplets are channeled through a drain to be collected in a tray mounted on the motor where the heat from the motor will evaporate it.

The drain of your freezer is probably blocked and has caused an ice build up. You will probably have to at least partially thaw and de-ice in order to find the drain and clear it. This is especially difficult as cold plastic is very brittle and easily broken. Great care is needed when clearing the drain as it is possible to dislodge the drain tube and if unnoticed it will saturate the insulation and render the freezer inefficient at best...

You have a problem in the de-frost system. Could be a timer, very common, heat element, very common. Look on line or your owner manual and see what that code is telling you. The average person can not make this repair. Hope it is under warranty.

I've just had a similar problem. I fixed it by removing the large panel on the back of the inside of the freezer. I found a large build up of ice at the bottom of the freezer which seems to have developed because the drain hole at the bottom of the freezer was blocked. I defrosted the ice, cleared the drain and now the freezer is working fine.

Either the door gasket is not sealing well or the unit is low in refrigerant.

Either the drain hose is plugged up with ice and not dripping into evaporator tray, or the defrost unit needs to be replaced.

first just take it out and clean that one carefully .And then set correctly and observe it,s working condition.then also it's not working means show it to ur near by worker those who repairs it

Hi, Are you seeing ice or frost? Is frost building up on the freezer back wall? I can help you, just need to be clear.
Thanks

My Bosch Frost Free Fridge Freezer did the same thing - Ice forming in the bottom of the freezer area after a few days.

It was caused by a blocked drain pipe - When the freezer does the de-frosting cycle, the melted ice drips into a tray and tehn runs into a dish on top of teh compressor, through a pipe.

If this pipe gets blocked, the de frosted ice overflows from the tray and overflows into the bottom of the freezer and then re-freezes !

To fix, pull the freezer away form the wall, locate the pipe that runs to the dish on top of the compressor and blow through it - This should clear it. Alternatively, from inside the freezer compartment, pull off the cover at the back, but the clips holding it on will probably break off, as mine did ! You can sort of push the cover back on and re-fit the food draws.

Not much you can do except ensure you have a tight seal and not to open it more than you have to.

Defected DEFROST HEATER can cause frost build up on the panel at the back of the freezer,and freezer stop cooling and ice frozen on unit so air could not flow to refrigerator side.Water will coming out caused of unbalanced freezing,and causing the flooding of water in the floor. You must change this defroster heater assembly so it will works normal again..


Hope this may help;
