Not every sound or drop of moisture means the refrigerator has failed. Start with the operating conditions, then look for a pattern.
Normal and unusual sounds
Fans, refrigerant movement, expansion clicks, ice makers and compressors all make sounds. A new model may sound different from an old one. Check that the cabinet is level, bottles are not touching and nothing behind the unit is vibrating. Grinding, repeated heavy clicking with no cooling, or a fan striking ice needs attention.
Condensation and water
Humid air enters each time the door opens. Check the door closes fully, seals are clean and food is covered. Water under the appliance may come from a drain, supply line, ice maker or another nearby source. Turn off the water supply if a visible line is leaking and it is safe to do so.
Heavy frost
A door left open, damaged seal, blocked vent or defrost problem can lead to frost. Do not chip ice with a knife or screwdriver. Move food safely and arrange support if ice returns quickly.
One compartment is warm
Make sure vents are not blocked and the selected mode is correct. Some models have holiday, power-cool or convertible-zone settings. After a large food load, allow recovery time. Persistent warming with correct use needs diagnosis.
It seems to run constantly
Hot weather, frequent opening, a warm food load and a low setting can increase run time. Clean only the user-accessible areas described in the manual. If the compressor never rests and temperatures are wrong, request an assessment.
