Whirlpool larder fridge ART647H warm

[Stephen99]

Hi,

Even with the dial turned up as far as it can go, my fridge is cooler than room temperature but not cold enough. I can hear the compressor come on occasionally.

To be honest, it has never been a particularly cold fridge; I remember the thernmostat being replaced under warranty because it was not cold enough.

I will put a thermometer in to get some accurate temperatures.

Is this model known to be a “warm” design? Is there something that could be wrong?

Thanks.

Hi,

I have left a thermometer in the fridge overnight and the temperature is stable at 14 degrees Celcius.

What’s the 12NC number?

It does sound like a refrigerant system problem though.

Hi,

I have opened the door and read the label but I can’t find anything beginning 12NC. Please let me know what it is and where to find it and I will let you know.

I have just checked the max/min thermometer. Min 14.9C and max 16.1C I haven’t opened the door since this morning.

Hi, Still not sure what you mean by 12NC. Is 8564-647-15000 any help?

Hello again,

Please can anyone tell me the correct way to remove and replace the thermostat?

I pulled the thermostat knob off and unscrewed the nut around the shaft. Then I slid the light fitting towards the door, more by luck than judgement, and it came off. By the way, the fridge was unplugged whilst I was doing this! Did I do this right or was there a better way?

I thought if I removed the old stat that I might be able to get a model number off it. The thing is, I don’t think the probe was routed correctly. Where should it go?

There is something that looks like trunking running from the light to the back of the freezer, where it terminates in a small square box. Should the probe go down there? If not, what is it for?

The thermostat probe was threaded through a hole in the side of the fridge, the same one that the cable for the light and thermostat comes out of. This also means that there is a right angle bend in the capillary. It just doesn’t look right to me.

I know the thermostat was replaced under warranty many years ago. I just wonder whether the replacement was put it in the wrong place? How long should the capillary be? The one on this is at least two foot long.

I also connected the two thermostat terminals together and the fridge is quietly humming away and the temperature has dropped from 15C to 10C already, so if the temperature continues to fall, hopefully this shows that everything else is working ok and it is a thermostat fault.

Hi, the fridge continued to cool to 6C, so I am now sure it is a thermostat fault. It seems I was wrong when I described the path of the capillary. I had another look and the mains cable comes along the trunking and the little white box, so that explains what that is. There is a small hole in the side of the fridge for the thermostat capillary to be pushed down and I have managed to push it without such a kink in it, which is an improvement, so hopefully it is just a matter of swapping it for a new one.
