    I HATE THIS FREEZER!!! Give me an old GE any day. The back and the bottom of the freezer fill with ice and the freezer stops freezing properly. I just broke off all the ice, again, but its still not cold enough to make ice or freeze my ice cream.

You need to remove the plastic tube that the water goes through . then take small saw and cut the flat part of the tube completely off . then slide the the plastic tube back in the bottom of freezer . apply a bead of silicone around the top of the plastic pipe (where you cut of the flat piece) so that the water does go into the insulation. whats happening - that flat piece sits up about a 16" too high at times and this causes a small pooling of water that becomes worse over time.... if you still continue with this problem take a short piece of 16 gauge wire wrap it around the calrod defrost heater a few times and insert the rest in your drain hole. this will heatup everytime a defrost occurs . which then melts the ice

Permanent ice on back side of fridge near the sensor (thermistor?)

Hello Paola! If your refrigerator is frost free, that is an indication the ice build up is caused by a failure for your defrost circuit. This circuit is made up of a defrost heater, defrost thermostat (both in freezer section behind the inner shield) and either a defrost timer (if your unit is older than 5 years) or the control board if younger. If you take off the shield in the freezer and the evaporator coil is coated in ice that is probably the cause. To check, defrost the unit by unplugging, and then use a hair dryer or heat gun to defrost all the ice off. NOTE: Be ready to deal with the massive amount of water from this defrost or you will have a mess. IF I am right, the refrigerator will start working normally for 2-3 weeks (depending on your humidity it could be shorter). Then you will get another ice build up and it will do the same thing.

My fridg and freezer is cold but not could enough the freezer wont keep food frozen. there is no ice build up, I replaced the defrost timer, and I cleaned the fan in the back what else could it be please...

Hello Nicole,

Their are a few things that couldbe causing your refrig.troubles.

1) their is ice build up in the return air vents that is not allowing air to flow correctly
you can see the air vents under the crispers in the ref.floor and can see if they
blocked with ice.

2) the freezer fan is bad and not circulating cold air into and out of the ref.

3) In addation to the defrost timer,perhaps the deforst heater and defrost thermostat are bad and frost is building up in the freezer,Do ya see frost
build up in the freezer??

Hi and welcome to FixYa, I am Kelly
Without your model number here is what most likely has happened:
The automatic defrosting system is not working due to a component failure.

The components of the automatic defrost system are:
1. Defrost control
2. Defrost heater
3. Defrost thermostat.
4. Wiring to inter-connect 1 - 3 above.

What your currently doing is a manual defrost cycle every 3 weeks because ice blocks the air-flow across the evaporator in the freezer compartment so everything starts warming up in the fresh food section first and finally the freezer as the ice block gets larger.

FYI you can unplug it... remove the contents from the freezer...use an external directed into the freezer compartment for just over 2 hours to do the same process your doing in 24 hours. Until the automatic defrost system is repaired you should do a manual defrost at least every 4 days.
Most units are on an automatic defrost cycle of 6 - 8 hours (usually) all the way up to 10.35 hours per cycle. Yours just is not working at all.

Thanks for choosing FixYa,

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 :-(

My LG GR-349SQF freezer keeps getting ice in the very bottom

I believe your defrost condensate drain is blocked with ice or other foreign objects. Could you also double check the model number? Thanks, Sea breeze

Can i turn off auto defrost in my whirlpool side-by-side freezer, food is getting freezer burnt after just 2 weeks

No you cannot turn off the auto-defrost as the unit would stop working at all after a short time, and there's no provision to do so anyway. And I don't understand why you would thing the feature would have anything to do with fFreezer Burn. Freezer Burn imay be somewhat affected by the temperature, but mostly how well the food is sealed, keeping air out of the package. If freezing packaged meats from your supermarket for instance, the air in the package will burn them in, yes as little as two weeks. If that is the problem, you must repackage those items, eliminating as much air contact with the food in the package as possible to avoid the problem. I myself use both plastic wrap and aluminum foil to repackage anything I want to keep a while.

Problem with Whirlpool side by side refrigerator (Model ED25RFXFW01). Approximately 6 weeks ago, I found the refrigerator had quit cooling and ice in the ice maker was melting. The top half of the freezer...

sounds like a defrost problem ...
maybe the heater or defrost thermostat is bad...

he should bypass the timer and jump the heater to see if its woking...if not then i would remove the heating element for further testing. if the heater checked would only leave the defrost timer to blame.

good luck

Refridgerator does not keep cool.Replaced the defrost thermostat and keeps doing the same thing. I have to unplug and thaw for 24 hrs and fridge works again for 2- 3 weeks and i have to repeat the thawing.

More often than not , when a defrost problem occurs , the defrost heater is the problem . With your G E , the heater is in a glass tube , below the coils . If you replace this , then the defrost timer would be the only part of the defrost system left .
