The short answer
Most Craftsman refrigerator noise is a fouled or contacting part rather than a failing one, and almost all of it is identified without a tool by noticing when the sound starts and stops. On this class it is usually the condenser fan fouled or worn at the bearing, with compressor mounting grommets hardened with age next to rule out.
What you actually observe
- It is loudest on the hottest afternoons — Longer run times mean more hours of whatever is making the noise.
- A noise loud enough to hear from another room at night — Background noise masks it all day, which is why these faults are reported at night.
- NEAR MISS: a grinding noise with water appearing on the floor — Water changes the diagnosis, and the leak page is the one to start from.
The causes, most likely first on this brand
- The condenser fan fouled or worn at the bearing — The fan that pulls air across the condenser sits low at the back where debris, packaging and pet hair reach it, and a blade that clips something rattles on every run. Ranked first on a Craftsman unit: garage dust is coarse and it packs a fan blade unevenly rather than settling on it.
- Compressor mounting grommets hardened with age — The compressor sits on rubber feet that go hard over the years, and once they do, normal running vibration is transmitted straight into the cabinet as a hum or a knock. Ranked second here: a compressor working harder in an unheated room runs longer and announces its mounts sooner.
- A cabinet out of level or touching the joinery beside it — Ranked third here: a garage floor falls toward the door by design, so the cabinet is rocking unless it was shimmed.
- The evaporator fan blade striking a build-up of ice — Ranked fourth here: last, and the humidity swing in an unheated room is what puts the frost there in the first place.
Check in this order, and why this order
- Listen at the back of the cabinet and see whether the noise stops when the compressor cycles off — A noise that ends with the run and returns with the next one belongs to the machinery at the back.
- Rest a hand on the compressor housing while it runs — Vibration you can feel through the shell rather than hear at a distance points at the mounts.
- Push gently on each top corner and see whether the noise changes — A sound that shifts under a hand is a mounting problem and not a component problem.
What an owner can safely check
- Unplug the unit, pull it out and clear the fan grille and the blade path — Anything that fell behind the cabinet ends up in that fan sooner or later.

- Level the cabinet on its front feet and make a finger's gap to the units beside it — A spirit level front to back and side to side settles this in a few minutes.

- STOP HERE if the next step needs a meter on live terminals or a panel off — That is where an owner check ends and a service call begins.
Before you open anything
Safety
Unplug the unit or switch off its breaker before any panel comes off or the cabinet is pulled out: a capacitor can hold a charge after the power is off. Fan blades keep turning after the motor stops and their edges are sharp. A full cabinet is heavy and top-loaded, so empty it before you move it and get help rather than walking it on a corner.
When to call a technician
Call once the owner checks are clean and the noise is clearly inside the cabinet, because a fan motor or a compressor mount needs panels off and a meter. Call sooner if the noise is a grinding or a scraping, or if it arrived alongside a cabinet that is no longer cold, since those two together point at a fault that is still getting worse. Bear in mind when you decide that a garage unit lives outside the conditioned envelope, which changes what counts as normal before anything is diagnosed.

This page covers the Craftsman refrigerator as a class, not one family or model line. Component part numbers, fan specifications and hinge hardware all change from build to build and are deliberately not here. Where a family or model page exists for your unit, it is the more specific answer and the one to read first.
