#2 How often does the fridge compressor come on?
I have mine in a cupboard adjacent to my bed.
If I open it to get anything, then it comes on to deal with
the change in temp. It's prob on for about 2 or 3 mins.
Then it's off for maybe 5 mins before coming on again.
Once it has dealt with the change in temp, I never really
notice it coming on again, it's relatively quiet and
unobtrusive.
But it does click on from time to time and I would guess
at perhaps every hour or so.
Sorry I can't be more precise. I suppose it all depends on
the ambient temperature around the fridge. I should say
that when you first plug it in, the compressor is probably
on for a good 30 mins or more.
