Hotpoint fridge freezer hmcb70301uk temperature advice

[Pidge22]

Hi all I have a hotpoint fridge freezer hmcb70301uk integrated ,it recently had a new board fitted however I wonder if someone can give me some advice re the temperature.Whenever I asked the engineer what temperature it should be running at he stated it was difficult to say as it was measured by the product temperature.
I have bluetooth digital thermometer on the bottom shelf & as per the screenshot during a day the temperature consistently fluctuates between 4 degrees at the lowest & 6/7 degrees at the highest is this normal? any advice appreciated

it will fluctulate as the door is open and closed the air temp will go up and down

the important thing is the mean temp of the stored products

try putting the sensor in water to get an idea what you milk will be doing. the liquid will not go up and down as fast and will reach an average temp

Hi Dave thanks for the reply the temperature goes up & down regardless of if the door is open or not below is a screen shot of the last hour & you can see it goes doen to 4.4 then climbs to 6 then will go down again which is what it does all the time ….

if you set a thermostat a say 4 degrees then you assume the fridge will get down to that temp and switch off
but
there is always an overrun and the temp will keep falling for a bit. then as the temp rises it will turn back on to keep the temp in the range. if they turned the compressor back on just above 4 degrees the compressor would be starting and stopping every 5 minutes or so. Would be very bad for the compressor not to mention energy saving. So there is a range where the temp will go between and it depends on the manufacturers design criteria possibly 2 degrees or so. also when it turns on it takes time for the compressor to start cooling the fridge compartment.
Add to this insulation which stops the heat of the room getting into the fridge. modern fridges have more insulation leading to smaller storage space. This is also affected by room temperature which gives a temperature gradient across the insulation. result the warmer the room the more the unit will run and temps will fluctulate

Thanks Dave and understand now you have explained thankyou I can only set as below & have got it on the Low (colder setting)

[electrofix]

as long as the fridge is in the safe zone I would not be too critical

Dave

[Pidge22]

what is the safe zone temps thanks

[electrofix]

2 to 5 degrees average
