Take the fridge out carefully (it is not difficult) after disconnecting the flue vent, disconnect the gas and short service cables and turn the unit upside down. Leave it for a while for the refrigerant gas bubbles to disperse, turn it up the right way and re-fit it after checking for LPG leaks. I did this a couple of years ago - on advice from a refrigeration fitter - and it worked. Now it seems I have to do it again (same problem as you).
If in doubt, get someone competent to do it for you.
