Bosch upright FrostFree Freezer too warm (GSU29421GB)

Temperature not going below -6 to -8. THis started about 2 wks ago after 10 yrs of excellent service. Super and Alarm lights are both on. Cannot find an easily accessable drain hole. Would it de-ice by emptying of food, switching off and leaving to stand with door open for about a week? If that doesn't fix it we would call in an engineer. Question is - is this worth doing?

    This solved the problem. No way to access the drain hole so I just emptied the freezer, switched it off, waited until no more water came out, switched it back on and it worked perfectly.

the evaporator is probably iced up and hence poor air flow. (i am assuming it is a frost-free type). switch off and leave for 24 hours with door open is the easy cure. otherwise, remove the back inside panel of the freezer and melt off the excess ice with a hairdryer used carefully

You have found where the problem is and now you must find what the problem is. The freezer is not defrosting tells you the problem is there. Defrost of the freezer coil is started by a timer, the time energizes the heaters, when termination temperature is reached the defrost thermostat opens, the timer continues until the time expires (18-22 minutes). First locate the timer, rotate the clutch head screw SLOWLY clockwise until on e click is heard. The heaters should come on a defrost take place. If timer restarts the system after the time period check the heaters for continuity. If no reading on an Ohm meter replace the heaters. If you find the heater O.K. by a continuity reading, check the defrost thermostat.

SOURCE: Bosch Fridge Freezer: Fridge Not Cooling

Your refrigerator's cool is provided by your freezer section through a damper - there should not be excessive frost on the cooling coils - the most common problem is a defrost timer - are you absolutely sure the noise you hear is the defrost this is the first thing to check, defrost control and its components, is it properly shutting off or stuck on during operation - the next thing to check is for possible sealed system problems / small leaks, door gasket seals, etc.

The fact that it started to work once you manually defrosted is the key here - an over forsted evap will cause the problems you describe most commonly - so have your defrost system checked completly and properly - that should solve the problem. followed by checking door gaskets, damper and sealed system - if only part of the coils are frosted as opposed to the entire surface, that usually a clue to sealed system leak - yes 10C is quite warm for a refrigerator. It should be between 34F-40F, optimal is 34F. And freezer section no warmer than 10F, optimal at 0F (-18C)

SOURCE: Bosch stand alone freezer Intelligent 32 - how to defrost

I have the same refrigerator and found the manual;
"The refrigerator compartment was programmed to defrost automatically meaning you do not have to constantly clean and dry it. Copy from the manual"
Also have a look in the back for the drain outlet - very small. If that is clogged up it also cause water on the inside.

My frostfree Kenmore upright freezer has been beeping alarm since the power was off for three hours this morning and showing -3 as temperature. What do I do to reset?

On some models the beeping will not stop until it gets to normal temp. The -3 is more than likely the set temperature of the unit. you can try to change that with the control. The best thing to do is get a thermometer to check what the actual temperature is.

Bosch freezer icing up

ice in the freezer is normally from the door being opened continuously and moist air being drawn in each time
or the door needs adjusting so that the seal is in contact all the way around it
freezer settings work opposite to fridge setting so 1 is minus 0-5 degrees, 2 is minus 5-10 and so on
try a default setting of 2 or three to start with
freezers are meant to store item until ready for use and are not meant to be opened all the time like a fridge door so it may require a change of habit in the freezer use.
another point
upright freezers are very bad in operation when compared to chest freezers because every time the door is opened , all of the cold air falls out onto the floor ( you can see it as a fog on some days )and that sucks in warm moist air into the unit which is where the ice is coming from

The refrigerator is not cooling in the refrigerator or the freezer

If you have a fridge or fridge freezer and the fridge is not getting cold it will be one of the following problems:

1, The fridge thermostat is faulty and not cutting in at the required temperature. Fridge stats are not easy to test, so the best way is to bypass the stat to see if the compressor starts. To bypass the stat first unplug the appliance and remove the stat housing from inside the fridge compartment, once you have removed the housing you will see the stat inside. Some stats have 2 terminals some have 3, whatever yours has you will need to connect the compressor wire ( Black) to the live wire (Red or White). When you have bypassed the stat plug the appliance back in and switch on, if the fridge starts up and runs ok you will need to purchase a new stat.

Types of thermostats:

There are various types of stats fitted to fridges and fridge freezers, the most common being the VT9 (pictured below) this stat will replace most larder fridge stats and most conventional fridge freezer stats. If your fridge has an ice box inside then you will need a VC1 type stat which has different temperature ratings. If you have an older Zanussi or Electrolux fridge freezer with one compressor and the stat is in the fridge then you will need a Reverse Action stat, as these type of appliances have a solenoid valve fitted into the pipework near the compressor and the stat operates the solenoid.

If you are replacing your old stat with a VT9 and your old stat only has 2 terminals then connect the new VT9 using the terminals marked 4 and 6 only. When fitting any new thermostat take great care not to kink the capilary tube as doing this will render it useless.

2, If you have tried bypassing the stat, and the compressor did not start then you have probably got a faulty compressor. To test for this is quite simple just listen carefully to your fridge and if the compressor is at fault you will hear a faint hum followed by a click, you will need to be patient as once it has clicked it could be 10 mins before you will hear the hum again. The reason you hear a hum is because the compressor is jammed and the hum is the motor trying to turn, the click that follows is the thermal overload tripping. If you have these symptoms it will not be worth repairing due to parts and labour costs.

3, If your fridge has lots of snowy ice on the backplate this is a sign that either the door is not shutting properly and letting in warm air thus creating snow, or it could be that you have lost some gas from the system and the compressor is working over time trying to get the temperature down. BE ADVISED it is rarely worth getting your system regased unless a leak can be located, as the gas will only leak out again and you will have the same problem in 1 or 2 months.

Frostfree fridge not cold

If you have a frostfree fridge freezer and the freezer is ok but the fridge is warm then your appliance is not self defrosting correctly, and if you could see inside the back wall it would be full of ice, this ice is blocking the airflow to the fridge compartment and therefore your fridge is warm. A quick fix for this problem is to completely defrost the appliance to do this you will need to move your frozens to another freezer then switch off your frostfree at the plug and leave off for 48 hours with the doors open and a large towel in the freezer to catch the water. After 48 hours plug it back in and let it run for 4 hours and you should find it will be working fine again, but you may find you will have to do this procedure every 6 months or so.

I have a Frigidaire model GLFU206FWA upright freezer. The temperature control won't go above 10 degree F. This causes freezer burn on some foods after a period of time. Is there a way to regulate the...

Good day,
Manufacturers of freezers do not give the option of running the machine much above that temperature. Normal operating temperature for a freezer is about -2 to about 8 above F.
Otherwise people could accidentally set the temp too warm and cause a loss of food.
Some appliance parts houses carry universal thermostats that could possibly cover the temperature range your looking for, but 30 degrees is far to warm to preserve frozen food safely.

Freezer cycling on and off rapidly

If it still maintaining temperature but is short cycling your control for the temperature is wearing out causing the short cycling. This is a replaceable part that can be obtained through a dealer or appliance parts supplier. By lower setting do you mean lower number on the control, or lower temperature setting? Normally the higher the number the colder the temperature.
