Turn off silent gadget in the kitchen (7)
I believe the answer is:
utensil
'gadget in the kitchen' is the definition.
'utensil' can be an answer for 'gadget' (I've seen this before). I'm not sure about the 'in the kitchen' bit.
'turn off silent' is the wordplay.
'turn' becomes 'u' (a 'U-turn' is a kind of turn).
'off' is an anagram indicator.
'silent' is an anagram of 'tensil'.
'u'+'tensil'='UTENSIL'
Can you help me to learn more?
(Other definitions for utensil that I've seen before include "Handy kitchen tool" , "Let us in (anag) -- implement" , "Implement for practical use" , "Can opener, for example" , "A tool for household use" .)
