what sort of noise? loud hum or buzzing every few minutes? how old is the fridge ?
does it click off then come back a few minutes later? or a continuous hum ? any frost buildup in the freezer section against the rear panel ?
Hi, welcome to Just Answer. My name is ***** ***** I look forward to helping you! The ice is the problem, the noise is the result of the evaporator fan blade hitting the ice. So, you have a defrost problem. There are several components in the defrost circuit, but the most common to be problematic is the defrost heater. It is mounted below the evaporator coil, behind the rear panel inside the freezer. It is a glass tube heater and easily broken. Do you have a meter to test it with and are you able to disassemble the freezer section?
That is an electronic control problem. How often does this happen?
Great, keep me posted!
