The short answer
A cabinet that runs continuously and still warms up has lost airflow far more often than it has lost refrigerant. The compressor is working; something is stopping the cold it makes from reaching the food. Listen at the freezer with the door open and the light switch held in. Hearing the evaporator fan separates an airflow fault from a fan fault before anything is opened. On a Staigis refrigerator the cause that ranks first is defrost cycle stalled, evaporator iced over.
What you observe
- The cabinet is warm but the compressor is clearly running — Cold is being made; it is not reaching the food.
- A solid sheet of frost on the freezer rear panel — The defrost system has stopped clearing the coil.
- The freezer is cold but the refrigerator is not — Airflow between the two compartments has stopped.
- NEAR MISS — the cabinet is silent and nothing is cold — That is a power or start-relay fault and it is a different page.
Causes, most likely first on a Staigis refrigerator
- Defrost cycle stalled, evaporator iced over — The heater or its control stops clearing the coil, frost builds into a solid sheet behind the freezer panel, and air stops moving while the compressor runs on. It ranks first on a Staigis refrigerator because a full-size cabinet has enough margin to hide a fault for weeks, so by the time it shows, the cheap cause has usually been running a long time.
- Evaporator fan motor failed — The fan behind the freezer panel is what pushes cold into the fresh-food side, and when it stops the freezer stays cold while the refrigerator warms. Second on this platform: a cold freezer beside a warm refrigerator is this fault and almost nothing else.
- Damper or air diffuser stuck — On a single-evaporator cabinet a flap meters cold air into the fresh-food side, and a stuck flap starves that side while the freezer stays fine. Ranked here because it mimics a failed fan exactly, so the fan has to be heard before this is considered.
- Condenser coil blanketed in dust — The coil rejects the heat the compressor removes, and once it is covered the machine runs continuously without ever getting the cabinet down. Last, and the reason to work down the list rather than guess: a shallow plinth or a tight cut-out fouls a coil far faster than an open back does.
Check in this order, and why
- Empty the freezer and look at the rear panel for a sheet of frost — A solid sheet rather than a dusting settles it immediately.
- Open the freezer, hold the door switch in and listen for the fan — A cold freezer with a warm cabinet is the fan's signature.
- Hold a tissue at the fresh-food vent with the door briefly open — Air arriving there rules the damper out; still air with a running fan points straight at it.
What an owner can safely check
- Empty the cabinet, switch it off and leave both doors open for a full defrost — Cold restored afterwards confirms the defrost system as the cause.
Tools: towelsAbout 45 min
- Unplug the cabinet and vacuum the condenser coil and its grille thoroughly — Do this twice a year on a compact or built-in cabinet, more with pets.
Tools: vacuum, soft brushAbout 25 min
- STOP HERE — the next check means a meter, a panel, or both — The ranking above tells you what to ask for; it does not make the remaining tests owner work.
Before you open anything
Safety
Unplug the cabinet or switch off its breaker before removing any interior panel — a capacitor can hold a charge after the power is off. Never cut, open or attempt to recharge a sealed refrigerant line.
When to call a technician
Call once the defrost, the coil, the door and the fan are all clean and the cabinet still runs warm: what is left is the sealed system, and refrigerant work is licensed work. On a machine at this price point, weigh any quoted repair against a replacement before agreeing to it: parts and labour reach the value of the appliance quickly.

What this page does not cover
This is the generalized page for a Staigis refrigerator. It does not carry anything model-specific: no part numbers, no wiring colours, no panel sequence and no torque figures, because those differ between families sold under the same badge. Where a family- or model-level page exists it is linked above, and it is the more specific answer of the two.
