help: hotpoint 8596p , freezer cold, fridge not

Hi there,
wonder if anyone can help ?
got a hotpoint mistral plus 8596p fridge freezer
the freezer is at -18c , ok .. the fridge is +22c

i have checked and done the following ..
1. fridge been turned off for 48 hours, totally defrosted
2. fan on rear back runs ok
3. cleaned all fins and vents and underneath
4. checked door switch .. ok
5. electronic flap in fridge working .. ok
6. door seals ok .
7. found and soldered 3 dry joints on circuit board.
8. moror seems ok warm and sounds like its spinning
9. set temp on top — still no luck

located evaporator thermister , green plug, brown and blue wires
removed this , and got error code E2 .. bypassed it still no good
the fan located in the freezer-rear panel top behind plastic cover
turns on when you turn the main on .. it spins for about 10 seconds and then stops .. but the temp was +18 at the time
maybe in time when its cooler it will start to spin again need to check tomorrow

iam slowerly runnig out of ideas …

can you help ???

cheers
