Im not sure how much it matters if the compressor turned off naturally before defrost or not. It makes sense, but the defrost happens so fast that it may not be necessary to do that.

Sure, the only reason i suggested that it is done directly after the compressor turns off is so the main fridge is at it's coldest and its temp is unlikely to rise when the compressor is forced off for a while.
Like you said if the defrost only takes 5-10 minutes there should be no problem really.
Mr Al said:... But with such short defrost times i dont think it takes that much energy. If you care to you could time the defrost cycle too and also see if it is sync'd to the compressor run time when it turns off.

I'll keep an ear out. It's noticable from the sound, which makes a quiet but very different sound to normal operation. From memory it takes 10 minutes or so but that is a really rough guess.
I have not heard it for a week or two so it is likely happening in the middle of the night now, or at a time whan I'm not near it. Next time I hear it I'll glance at the clock and see how long it takes.
It's a shame we don't have a fridge repairer here on the forum who knows all these stats offhand!
