Schreiber 50/50 Frost Free Fridge Freezer APM6855

[richardc1983]

I have just moved into my first bought house… over the last month though I have had to defrost the freezer as the fridge section was starting to get warm and was constantly running to get the fridge temp down.

I took the panels out and defrosted 3 weeks ago throughoughly to which it worked well for the last few weeks since then temp is struggling and maintaining at 8c when its set at 4c however the fridge thinks its at 4C as the display indicates 4c however my digital thermostat indicates 6-8C.

Found this thread http://www.howtomendit.com/answers.php?id=106888 and most people saying its the no frost thermostat with the following part to replace it http://argosspares.co.uk/cgi-bin/search … 00&x=9&y=5

However I have since found this part on your shop http://shop.ukwhitegoods.co.uk/Refriger … Probe.html which is a little bit cheaper than the argos spares. My concern is though that in the thread linked above there are 2 version of this prob one for model number 0 and 1. The variations being that one has a digital display the other doesnt. I am not sure what my model number is as the manual doesnt say and the sticker in the appliance just shows APM6855.

How does the defrost work on these fridge freezers I know it is cycling off as once its reached temperature the compressor goes off however why is it freezing up still and how does it thaw itself out? Previous owners said they never had a problem with it. Also dont fancy pulling fridge/freezer out when it is in a cupboard. So could I just cut the wires to the existing sensor and use a cable block to secure the old wires with the new wires or should it be replaced back to the PCB?

Any help appreciated. I think the main difference between the two version of sensors is the connecting plug?

Hi Samuri

Thanks for your replies, its been about 3 weeks since I last defrosted and the fridge section temp is slowly rising from 4C to 6C. Problem is the display says that it is at 4C but my digital thermometer inside says its at 6.2C. Once I have done a full defrost digital thermometer reads at between 3&4C for a few weeks before it starts to increase again. Bread in the freezer is the first thing to start to go soft meat remains solid.

The evaporator is iced up fully and I notice it runs for longer to try to pull the temperature down. I have now bought the part http://www.ebay.co.uk/itm/140751429164? … 26_rdc{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d}3D1 which says Manufacturers code is 502023500 which I hope will be a straight unplug & swap from the back of my freezer electrical compartment.

Kwatt further up said that its wishful thinking hoping its the sensor at fault and its normally the control pcb – surely if it works fine for a few weeks and everything is held at the correct temperature quite accuratly that says the pcb is functioning? The freezer is also at the correct temp during this time also. The temp slowly starts to increase from say 3/4C then goes upto 5C – 6C then 7C perhaps 2/3 days (as the evaporator ices up more) before each degree of temperature increase.

The only other thing it could be is the defrost heater? Hoping it isnt though as I know this cannot be replaced as its part of the evaporator. In your experience should the sensor rectify my issues based on the symptoms. Its just with what Kwatt has said about them very rarely failing… I also came across this forum post… http://www.howtomendit.com/answers.php?id=106888 which seems to suggest it is the probe that fails however a few people have said after a few weeks of replacing the sensor it is freezing up again. But works ok in those initial few weeks so if that is the case for me would it be the PCB or defrost heater?

Its obviously not worth spending £80 on a new PCB when I could possibly get a new replacement for £350… can you reccomend a suitable replacement. I would prefer frost free though.

Thank you.

Hi Richard

Rather than merging this thread with your original one Name of white probe in freezer unit (Schreiber APM6855) which I don’t think would flow I’ll lock this one.

Much easier if you keep it to one thread as it causes less confusion 😉
