Question about Refrigerators

My Bosch KGU3420GB fridge freezer keeps getting a thick layer of ice in the bottom of the freezer which then 'welds' itself to the bottom freezer draw. Any idea how to fix this?

Sounds like the drain is blocked and defrost water is collecting in the base. Try a full defrost and check the drain hole clears.

Madezmom, you have a defrost issue. If your model starts with 106 you more than likley have a bad defrost bi-metal, I will attach a picture of bad one. This sits on the evaporator in the freezer section behind the panel. You will have to remove the shelves and remove the back panel. Defrost the evaporator completely. The part number for the bi-metal is 2196155. See if yours is bulged like the one in the attached photo. If so, that's your problem..Catriver..post back.

SOURCE: water dripping from freezer to fridge

Sounds like the drain for the defrost cycle water may be plugged and you eventually overflow water. See if you can find the little drain hole for the coil defrost water and check for dirty/plugged. Try to pour hot water in the drain area and see if it runs out the drain fast (if real slow it's a problem). Make sure the water is also going down to the holding pan near the bottom area/compressor area (that's where it evaporates later). Let me know what you find.

SOURCE: Bosch frost free fridge freezer

Such a frost build-up usually indicates a problem in the self-defrosting system or damaged door gaskets.

The refrigerator is supposed to self-defrost approximately four times in every 24 hour period. If one of the components in the self-defrosting system fails, the refrigerator continues to try to cool. Eventually, though, so much frost builds up on the evaporator coils that the circulating fan can't draw air over the coils. There may still be a small amount of cooling because the coils are icy, but with no air flow over the coils, cooling in the refrigerator compartment is quite limited.

Here's an inexpensive, though inconvenient, way to determine if the problem is with the self-defrosting system. Remove all of the perishable food from the refrigerator and freezer, turn the thermostat in the refrigerator to Off, and leave the doors open for 24 to 48 hours. (Be sure to have several towels ready in case the melting frost and ice causes the drip pan to overflow). This allows the refrigerator to defrost "manually." When the frost and ice build-up has completely melted away, turn the thermostat back to a normal setting. If the refrigerator then cools properly, it indicates a problem with one of three components in the self-defrosting system:

  • The defrost timer


  • The defrost thermostat (also called the bi-metal switch)


  • The defrost heater


If it still does not cool properly, there may be a problem with the refrigerant level or the compressor. You may need to consult with a qualified appliance repair technician to further diagnose the problem

Bosch intelligent frost free 88


We have the same and I think it is because the freezer door bounces open when we shut the fridge door. Then the freezer compartment ices up, the fan clogs up with ice and cannot blow cold air into the fridge, and the fridge gets warm and the milk goes off.
Solution? We have bought one of those child safety clips (search for fridge safety clip or lock) to hold the freezer door closed.
Simple design error. Expected better from Bosch :-(

you will find either 1) there might be a ice blockage on the evaporator. This in turn can stop the evap.fan motor which is supposed to circulate the frost .Defrost with a hairdrier once panel is off or switch orr for at least 2 days to defrost. (insulation is very good. retry.or 2) sometimes you have an auger at top of fridge compartment. If it sticks, reduces ability to cool.Also switch off. use hairdrier to remove ice build up at auger outlet. retry. .

My Bosch frostfree fridge freezer keeps icing up!


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.

Sears Coldspot 17 frostless freezer not defrosting


One reason for the fan running is that it is trying to distribute the air in the compartment. Look at the very rear of the freezer on the bottom and see if the little vents, which allow water to disperse, are not filled with frozen ice. If so, turn off the fridge (unplug it) and use a hair dryer to melt that ice until it is all gone. That will probably fill the condensation pan under the unit and you'll need to empty it.

Ice build up in bottom of freezer


Check the ice maker. sometimes they get cracked a will leak water into the freezer compartment. Also check the ice maker fill tube for leaks or someone could have spilled something. Although this is tipical of a clogged drain. What happens is when the fridge go into derfost, it will melt all the frost that is on the evaporator, turning it into water. The water drains down to a trough under the evaporator and down a drain hole in the trough ( this trough is behind the evaporator cover ) Removing the melted frost from the freezer. If that drain is clogged, the water cannot leave the freezer. Then when the fridge starts back up ,it will freez the water that was not drained. After repeated defrosting the water will fill this trough and run off into the bottom of the freezer to be frozzen when the fridge starts to cool again.
