Does Your Refrigerator Sound Like A Haunted House?

Fear not! These may just be normal operating sounds. Your refrigerator has an evaporator, located in your freezer section (hidden away from view) that accumulates frost during the cooling process. When the refrigerator goes into a defrost cycle, a heater element switches on to help melt this frost off the evaporator. On occasion, the melting frost will come in contact with the element causing a hissing sound. Some refrigerator models will have vent slits on the back panel and this element may be visible when it’s on, glowing red. Don’t be alarmed, it’s doing its job.

A cracking noise may also be heard during this defrost cycle. It will sound like snow crunching under your foot. As the frost is melting off the evaporator the change in state will cause that crunching/cracking sound. This is also another normal sound of your refrigerator during this cycle.
These sounds will only be heard during this defrost cycle. If you hear more rhythmic or pronounced sounds don’t hesitate to contact us and we’ll be happy to send out one of our qualified technicians to inspect the unit.
