Thanks for the advice. Tried again last night and he went for it, he acted strangely though and came right up to the top of enclosure in the S position which he has never done, even though the food was below him.
Still looks like your food wasn't warm enough and that's why he came all the way up - your hand was warmer than the mouse/rat.
I get mine over 100F when I get ready to feed and have no trouble.
