Re: Meile KFN12923 – Fridge only triggers cooling at 14ºC

Update – I’ve replaced the fridge temperature sensor and the problem still persists. I’ve even left the whole fridge/freezer switched off at the wall for 5 days to make sure everything had defrosted.

So I can only imagine it’s the fridge evaporator sensor (based on other people’s forum posts).
Can somebody let me know how hard this is to change? Does the back of the fridge need to be taken off?

If it’s difficult I’m taking the fridge to the scrap yard as I’ve spent enough time on it already.

Thanks
George

Right, I’ve received the replacement temperature sensor.
Next problem, how can I replace it without damaging the back of the unit?!

It looks like I need to remove the black condenser coil/grill as it covers pretty much the whole of the back of the fridge. But with all the connected pipework it doesn’t look like it’s designed to be moved out of the way.

I see six bolts holding the black condenser coil/grill part on, if I undo these bolts will the coil fall/move and be damaged?

If anybody can give me any tips on what to do here I’d appreciate it as I haven’t a clue. I’ve searched the internet for information but drawn a blank.

Thanks in advance,
George

Excellent, thanks for your help Bob. Hopefully it comes with instructions and won’t be too difficult to fit. I’ll get one ordered at the weekend.

Cheers

That makes sense, thanks SAMURI.
Do you know of any places which sell these kits?
Or do you know where I can find the part number for the kit?

Thanks again for your help.

Thanks Bob.
Most of the time the compressor is not running and feels cool/warm when touched. It only seems to get hot when it’s running. If it was struggling to deliver cooling to the freezer would you not expect it to be hot for a larger percentage of the time as it’s doing more work?

Also when I left the fridge door open to speed up the warming up of the fridge it started cooling about 10 minutes later, when it reached 14ºC. Based on the readings from the previous days I know that if I’d kept the door shut it wouldn’t have started cooling for another hour or two.
That indicates to me that it’s deliberately holding off cooling until 14ºC.

The temperature sensor I’m using does work below about -10ºC, if I can get one that does I’ll put it in the freezer and monitor the temperature there.

Thanks
George

Thanks for your reply SAMURI.
I felt the compressor when it was running one time and it was hot, I couldn’t hold my finger on it for more than a couple of seconds. At other times when not running it’s cool/warm.
Does this mean it’s a refrigerant fault? Is that repairable? How much will it cost!?

Thanks
George

Oh and also there’s no temperature warning alarms sounding.
Thanks
