Vermin run up round top of oven, making you draw back (6)
I believe the answer is:
recoil
'draw back' is the definition.
(I've seen this before)
'vermin run up round top of oven' is the wordplay.
'vermin' becomes 'lice' (I've seen this in another clue).
'run' becomes 'r' (cricket abbreviation).
'up' says the letters should be written in reverse (in down clue: letters go upwards).
'round' means one lot of letters goes inside another.
'top of' indicates taking the first letters.
The initial letter of 'oven' is 'o'.
'lice'+'r'='licer'
'licer' in reverse letter order is 'recil'.
'recil' going around 'o' is 'RECOIL'.
'making you' is the link.
(Other definitions for recoil that I've seen before include "Draw back in fear or disgust" , "(As a firearm) spring back" , "Spring back; flinch" , "Spring back in horror" , "kickback" .)
