Freezer problem - what temp should it be running at?
Discussion
I replaced my kitchen 2 months ago and I decided to go for an 'every thing bult in' approach. The Fride Freezer was installed and I transferred all my frozen food from my old freezer. I didn't think anything was wrong until I took some ice cream out and noticed that it was much softer then when in my old freezer. I checked the temperature with a freezer thermometer and fond that it was running at -12C. I checked it a couple of hours later at it was -20c. Just to be on the safe side, I called an engineer out. He re-gassed it and it appeared to be working ok. But because I had started to loose faith in it, I bought a data logger and checked the temperature over a few days. I was suprised to find that the freezer was alternating between -18c and -12c every couple of hours. I found that if I turned the control up it would get colder than -18c, but the upper temp would stay around -12c.
I contacted the service dept again and they said that this was normal operating.
What does the PH team say?

I would imagine that a freezer is either on or off. So when the temperature gets up to -12 it fires up and takes it down to -18, then switches off. It cannot maintain a constant temperature. The compartment will then start to warm up gradually until it reaches -12, and round it goes again. However, whether 4 degrees is a normal range I don't know.

I used to work for a datalogging company, we did a lot of fridge/freezer monitoring (admittedly in lab environments, but often using domestic fridges/freezers) - normal operating for a freezer was to sit between -16 and -22, mostly between -18 and -20 (all degrees C) - the only ones that would get as high as -10 would be ones being opened very often - I'd say your freezer has either a faulty thermostat or a faulty door seal...
This guy told you he re-gassed it?....Did he find any gas leaks?...
(all fridges and freezers are hermeticly sealed from the factory so shouldnt need gassing up its whole life).
The diiferental on your thermostat should be around 3 degrees....So compressor cuts in at -17 and cuts out at -20.
Sounds like a dodgy thermostat to me.

depends on where you are measuring the temperature.... Frost free freezers have the evaporator behind the back panel inside the freezer and a fan ducts the air through here and out into the freezer compartment. If you measure the temperature somewhere in the air flow from the fan, the temperature will read far lower than the actual mean temperature in the freezer. If its a normal, non frost free type(a lot more reliable IMO)then its the shelves themselves that are the evaporator so a temperature probe touching a shelf will again give a far lower reading.
As this this appliance is built in has it been installed correctly allowing for air flow as per the instalation instructions? and is the outer door panel correctly fitted so the door is closing and sealing correctly. Or is your kitchen particualrly cold at the moment? If it is a Fridge freezer then the temperature is controlled by the Fridge temperature rather than the Freezer temperature. IE. if the fridge is reading cold enough then the compressor may not be coming on at all, or not often enough, which is why so many fridge freezers in garages wont work in winter as the temperature outside is colder than a fridge inside temperature meaning the thermostat or temp sensor will never bring the fridge on and the freezer defrosts as a result.
Finaly, if it is frost free, do not over fill it an make sure the vents in the back of the indside are kept clear to promote the air flow.
Mind you, did he really re gas it? Not something we generaly get involved with on such a new appliance as it would indicate, as someone else pointed out, a more serious leakage problem.
Having said all this though, Candy are crap with a capital C!

^^^^^ Probably that. I have a vent at the bottom of the fridge/freezer at the front,this accumulates household fluff and needs a regular vacuum otherwise the temp of the unit goes up and the freezer defrosts!
