Noises You Might Hear

Your new refrigerator may make sounds that your old one did not make. Most of the new sounds are

actually are. The following describes the kinds of sounds you may hear and what may be causing them.

Mode.

Possible Causes

Check the main electrical box and replace the fuse or

reset the circuit breaker. Do not increase fuse capacity.

If the problem is a circuit overload, have it corrected

by a qualified electrician. Reset the circuit breaker on

the GFCI. If the problem persists, contact an

electrician.

Turn the control ON. Refer to the Setting the Controls
