The short answer
A Craftsman refrigerator that runs without cooling is almost never the compressor, whatever the noise suggests. On this class the fault is usually an ambient temperature outside what the unit was designed for, with a condenser coil smothered in dust, lint or pet hair next to rule out, and both are visible to an owner in minutes.
What you actually observe
- It struggles in high summer and again on the coldest nights — Both ends of the year are hard on a unit outside the conditioned envelope.
- Condensation or sweating inside the cabinet — Warm humid air getting in, or cold air not circulating, both show up as water on the shelves.
- NEAR MISS: the unit is silent and nothing at all is cold — That is a supply or start-component fault and it belongs on a different page. A reader seeing this should leave for that one.
The causes, most likely first on this brand
- An ambient temperature outside what the unit was designed for — Cooling capacity is specified against a room temperature band. Ranked first on a Craftsman unit: a garage sits outside the conditioned envelope, so the first question is whether the unit is being asked to work in a room it was never rated for.
- A condenser coil smothered in dust, lint or pet hair — The coil is how the unit sheds the heat it pulls out of the cabinet. Ranked second here: garage dust is coarser than kitchen dust and it packs a coil rather than settling on it.
- A stalled defrost cycle icing the evaporator — Ranked third here: swinging humidity between a cold night and a warm afternoon loads the evaporator with frost far faster than a kitchen does.
- A sealed-system fault or a compressor that no longer pumps — Ranked fourth here: last, because the failures above account for nearly every garage-unit call before this one is reached.
Check in this order, and why this order
- Measure the air temperature where the unit actually stands — A reading well outside a normal room is the answer before anything is opened.
- Look at the coil at the back or behind the lower grille — A visible mat of dust, or a coil that is hot along its whole length with the fan running, confirms it.
- Pull the freezer contents and look at the rear panel — Frost as a solid sheet rather than a light dusting is the signature, and it separates this cause from every other one without a tool.
What an owner can safely check
- Give the unit shade, ventilation or warmth as the case requires and re-check over a full day — Treat this as a diagnosis, not a repair: a unit in the wrong place fails the same way every summer.
About 30 min
- Unplug the unit and vacuum the condenser coil and its fan grille — A soft brush first, then the vacuum. This is the single most productive thing an owner can do to a refrigerator.
Tools: vacuum, soft brushAbout 20 min
- 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: a capacitor can hold a charge after the power is off. Leave the door switch wired as it is, because it cuts the fan for a reason. Never chip ice off an evaporator with a tool, since the refrigerant tubing runs directly behind it.
When to call a technician
Call once the owner checks come back clean, or the moment the evidence points at the sealed system: refrigerant work is licensed work. Call immediately if you smell burning or see oil at the compressor, because that means the system is open and every further running hour makes the repair 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.

What this page does not cover
This page covers the Craftsman refrigerator as a class, not one family or model line. What changes from build to build, meaning wiring colours, component test values and part numbers, is 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.
