🙁 I have a Siemens VARIO electronic Fridge/Freezer
Approximately 3/4 years old,
It has developed the following fault. On switching on both freezer/fridge run normally up to cold temperature set.
On reaching this set temperature the motor switches off as you would expect. But the motor fail to restart as the temperature rises.
By switching the freezer off then on it will repeat the above cycle
Any ideas as to if this is a thermostat problem or circuit-board problem?
Do you stock a replacement item if so what cost including postage and also the availability?
The following serial numbers are on the motor
AE110E13RBY58D9C
SXH3783351
25572
DA110E13RBY5
Bar-coded number 293780613404
Thank you for your help

Re: Siemens VARIO electronic Fridge/Freezer
Hi
When you give full information it always helps 😀
What you have is a failed foamed in NTC sensor.
What you need is a kit p/no 491415. available by emailing spares@ukwhitegoods.co.uk.
If some idiots come on here suggesting cutting into wall of appliance to change sensor, please ignore them. :nono:
For the sake of about a tenner, its far better than butchering your lovley applianace 😉Power off if you are to attempt any work on the appliance :plug:

Re: Siemens VARIO electronic Fridge/Freezer
Cheers Greg. Is it a straightforward job to replace the faulty part? Any special tools needed? Could you give me some clues as to how to do it. Or would it be better to call an engineer?

Hi
Its a matter of bypassing the ntc in question.
Kit basically contains two ferrules and an instruction sheet to explain which wires to cut and join.
Due to limitations on here, we cannot give you this information, sorry.
Only specialist tool you will need is a crimping tool 😉
Its not rocket science to do the job IMHO 😀Greg
Re: Siemens VARIO electronic Fridge/Freezer
Hi Greg,
It sounds like I have the very same problem but I thought I’d just check with you if that’s ok before ordering the thermistor removal kit.
I too have a Siemens Fridge/Freezer (KG31V04GB/06) and although it does not need turning off and on again to get the temperature down, I do find on occasion that the freezer has risen in temperature to almost 0. The next time I look it’s back to its normal termperture.
I have turned ‘super’ on and set the thermostat to it’s lowest temperature setting (5) and am waiting to see if it happens again – I have just checked and I think it might be as the temperature guage set within the freezer door is above its normal range..
I pulled the fridge out and dusted down the radiator and noted that one of the feeds to the radiator was very hot so I’m guessing that the pump and gas are still working fine.
I have checked the door seals and they’re fine too.
Finally, I thought a thermistor was a thermostat. If this is bypassed what prevents the fridge and/or freezer from going way too cold?many thanks in advance for your time,
Ian.
Re: Siemens VARIO electronic Fridge/Freezer
Oh dear! 😯 this one seems to have slipped under the radar!
Ian, A thermistor is not “the same” as a thermostat.
A thermistor is a resistor which alters in value according to it’s temperature.
they come in both Positive Temperature Coefficient (PTC ) -or Negative (NTC).
There are many different value-ranges within each type and specific individual types have well-defined operating ranges, thus they can be connected to an appropriate electronic circuit to react to a specific temperature.What Greg suggested, was to DISCONNECT the failed unit and SUBSTITUTE it with the modification kit. the original item was “built-in” during manufacture without any thought of replaceability if (read WHEN) it failed.
Re: Siemens VARIO electronic Fridge/Freezer
Hi Steve, I meant that the thermistor was doing the same job as a thermostat as in when the resistance hits a specific value the temprature must be at a particular point. I have indeed shorted it out even though it’s resistance was as expected (about 10kohms if I remember correctly) but as my fault is intermittant I wasn’t too surprised. I am monitoring it and so far so good. 🙂
Re: Siemens VARIO electronic Fridge/Freezer
Ian, please understand that many others will read this thread and will not necessarily have the judgement or skill to delve too deeply.
therefore, I am not trying to insult 🙂It is very unwise to SHORT OUT any electronic component…….the thermistor, in this instance, allows a limited current to flow….a lower resistance will allow a bigger curent to flow (this could be used to “switch” a transistor, for example.
shorting out the thermistor could well overload such a transistor and “blow ” it
Fine, if you are able to diagnose and replace it………but what if it’s part of a large, custom-programmed chip specific to that appliance……your expertise is useless in that instance,- you’ll HAVE to pay the price for a new board.
In short, NEVER SHORT_OUT A COMPONENT. unless you really understand what you’re doing. substituting is a different game altogether…in this case an appropriate combination of fixed and variable resistors would make a simple and safe test-substitute.
Hope that clarifies things for future browsers. 😀
