Thanks for taking the time to reply. Did switch it off!

The bottom vent did have visible ice build up, so melted that first. Any idea if I should definately be able to feel the warm air blowing from the salad tray vent, when blowing up the top freezer pipe, or is that the other end of the one at the bottom of the freezer?

Will try again tonight, with the hairdryer then.

Failing that, will resort to the other suggestion of defrosting it completely for 24 hours - shame to waste all the food though...
