Noise from freezer

Hi!! you will need to replace a sensor in the fridge behind the back cover! this is due to iceup around the fan in this back cover! even if you defrost it, it will do it again so turn off from plug for 24 hours but leave the fridge door open other wise it wont totaly defrost! then open back cover in fridge with care and you will see a small white plastic attached on double wire which is pluged in to a socket on the right side in a squre box! very rare somtimes the heating element goes too which has to be tested! you can use a steam machine to defrost it in an hour which is safe providing you dont put steam in to the electics in the squre box! oh make sure you take plug out before you start to steam. take care when doind this to take off back cover in fridge as if you force out the cover without melting the ice behind it it will damage the cover! in expert hands it looks easy so good luck!

Sounds like the compressor unit has gone out. It will need to be replaced. When you call somebody to come out and fix it, make sure its a company that is trusted and bonded. Call around and get estimates.
