The short answer
On Frigiaire the noise you are describing is most often a sound that is normal for this platform. Ranked that way because with no display to consult, the diagnosis is entirely what you can hear, feel and see.
What you observe
- A buzz or rattle that comes and goes — It is following the cooling cycle, which tells you which parts are even running when it happens.
- A hum you can feel through the floor or the worktop — Transmitted vibration rather than a failing part, in most cases.
- NEAR MISS: the noise is there but the cabinet is also warm — Then the noise is a symptom and the cooling failure is the fault. Read the not-cooling page for this brand instead.
Causes, most likely first on Frigiaire
- Sounds that are normal for this platform — First on a machine this size, where the owner is close to every part of it. Expansion ticking as the liner changes temperature, a gurgle as refrigerant settles, water trickling to the drain pan after a defrost, and a compressor that changes pitch rather than switching off. None of these are faults, and chasing them wastes a service call.
- The cabinet is out of level or touching something — Second: on a small machine this is quick to confirm and quick to rule out. A rattle or a drumming that appears only at certain times. A cabinet standing on three of its four feet, or one whose side is resting against joinery or a wall, turns a normal vibration into a noise the whole kitchen hears.
- The drain pan is loose, or water is dripping onto it — Third. A sizzle, a trickle or an intermittent clang from underneath, usually starting shortly after the cooling cycle ends.
- Bearing or compressor wear that is a service call — Last, and it is the reason the order above matters. A metallic scrape that gets worse week by week, or a compressor that has become noticeably louder than it was.
Check in this order, and why
- Note whether the sound arrives on a cycle or runs constantly — Cyclic sounds are usually normal; a constant new noise usually is not.
- Rock the cabinet gently at each front corner and check the clearance on both sides — It is the cheapest check on the list and it fixes a surprising share of complaints.
- Look underneath at the pan and check it is seated in its clips — It explains an intermittent noise that arrives on a cycle rather than continuously.
What an owner can safely check
- Log when the noise happens over a day: after a door opening, on a cycle or constantly — A pattern is worth more to a technician than any description of the sound itself.
About 10 min
- Level the cabinet on its front feet and open a finger-width gap on each side — Adjust the feet until it sits solid with no rock, then confirm nothing touches it.
Tools: adjustable spanner, spirit levelAbout 20 min
- Pull the lower grille and check the drain pan sits square in its clips — Reseat it if it has been knocked loose.
Tools: torchAbout 10 min
- STOP HERE if the next step needs a meter on live terminals — That is where an owner check ends and a service call begins.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel or reaching behind the cabinet. A capacitor can hold a charge after the power is off, and a fan blade you cannot see will start the moment power returns. Never hold a door switch in with tape and then walk away, and never reach into a running fan to locate a sound.
When to call a technician
Call when the sound is metallic and getting worse, when it comes from the compressor itself, or when the checks above have all come back clean and the noise is still there. A scrape that deepens week by week is wear, and wear does not reverse. Call sooner if the noise arrived together with a cabinet that is no longer holding temperature, because then you have two symptoms of one fault and the cooling one matters more.

What this page does not cover
This page covers the brand and the refrigerator class, not one family or model line. Where a family-specific or model-specific page exists for your unit, that page is the more specific answer and it takes precedence over this one. Not here: part numbers, wiring colours and component locations, which differ by family.
