Hi thanks for choosing just answer
Does if make.a clicking noise also? And are you talking about the freezer fan?
Yes it does make a clicking sound ...and yes it could be the freezer fan.
I mean the fan you are hearing is it in the freezer or on the back of the fridge?
sorry... it seems to be freezer, not coming from the back of the fridge
And you say rapid how fast would you say?
cycling every half second
Ok there is a defrost control that has a relay on it that will shut off fan this is the only thing that could cycle it that fast , it usually runs about 80-100 dollars. This should fix the problem.
is it user installable ?
Yes it just plugs in just gotta make sure its unplugged so you don't get shocked
ok ... thx !
