If the refrigerator is noisy or loud, especially when the door is opened, check to see if the fan blade in the compartment behind the back panel turns freely. If not, see if the blade is rubbing against anything. Correct any rubbing and try again. Also, check the condenser fan blade to see if it's rubbing or if something is caught in the fan blade. The condenser fan is either underneath in the back or on the top of most built-in refrigerators.

If the refrigerator is noisy or loud the evaporator fan motor might be worn out. These fan motors often make a chirping or squealing noise when they fail. They can also make a loud rumbling or grinding noise. If this is the problem, the noise will be much louder when the door is opened. If that's true, replace the evaporator fan motor.
