Newer Frigidaire refrigerators with variable-speed compressors and multiple fans can sound quite different from an older model, which leads plenty of owners to worry about perfectly healthy appliances. It helps to know what you are hearing.
Sounds That Are Usually Normal
- Humming or a low whir: the compressor and fans running. Variable-speed compressors may run longer and change pitch.
- Gurgling or bubbling: refrigerant moving through the tubing, often just after the compressor stops.
- Sizzling or dripping during defrost: water melting off the evaporator and landing on a warm heater.
- Cracks and pops: plastic liners expanding and contracting as temperature changes.
- A buzz followed by a thud: the water valve filling the ice maker, then ice dropping into the bin.
Sounds Worth Attention
- Squealing, chirping or grinding that changes when you open the freezer door. That often points to the evaporator fan, sometimes with ice touching the blade.
- Rattling or scraping from the bottom rear: can be the condenser fan or debris near it.
- Loud clicking every few minutes with no cooling: the compressor may be trying to start and failing.
- A constant buzzing from the water valve when the ice maker is not filling.
Simple Things to Rule Out
Make sure the refrigerator is level and not touching the wall or cabinets, and that nothing on top of it is vibrating. A drain pan that has shifted can rattle; check whether your manual lists it as owner-accessible before touching it, and unplug the refrigerator first.
If a noise is new, loud and paired with temperature changes, do not wait for it to stop. Note when it happens and book a refrigerator repair visit.
