"manuals specifies 6.3V for the rpm and not a variable one so I assume that it would be constant from the fan."
Don't see any reference to 6.3 anywhere in the doc. Attached is a pic of the J2 connector on page 26 of the PDF.

"correct the logic may be to keep the fan at the same speed regardless as it doesn't know what speed"
The manual says it defaults to high speed
"Check what voltage is seen on it."
Will do"
"Does the fan in the quick chill drawer fan work OK?"
Checked early on and it was working.
"Did you check the refrigerator door seals"
Tested ok a month or so ago; if they were leaking the so called vacuum we discussed previously would not be evident.
