The answer first
A warm FN refrigerator with the compressor running is a cooling-path fault, not a power fault, and that narrows the list to four candidates. Two of them are conditions rather than broken parts — where the cabinet sits and how the door closes — and both are free to exclude. A refrigerator holds food safely at 40 °F (4 °C) or below, so use that as the target rather than a guess about how cold the box feels.
How the fault presents
- The compressor runs and never cycles off — A unit that cannot reach its set point never gets the signal to stop, so it runs continuously and the same fault is visible from the other side.
- It stopped cooling within a day or two of being moved — Clearance, level and a knocked control account for most faults that appear on that timescale.
- The machine sounds normal but nothing inside is cold — A running compressor proves the motor is turning, and nothing else.
- NEAR MISS — the cabinet is warm and the unit is completely silent — That is a no-power or start-relay fault rather than a cooling fault, and it is a different article: check the socket, the cord and the breaker first.
Causes, most likely first on FN models
- Condenser coil choked, or no clearance around the cabinet — Heat leaves the refrigerant at the condenser, and a coil packed with dust or a cabinet pushed tight into a recess cannot do it. First on this family because it needs nothing taken apart — on a cabinet this size it is a look and a listen, and excluding it costs less than five minutes.
- Evaporator iced over, so the air path is blocked — Frost belongs on the evaporator; a solid sheet across it does not. Second on this family: it produces the same complaint as the cause above it, so the two have to be separated before either is acted on.
- Room temperature outside what a compact cabinet can hold — A small refrigerator in a hot garage cannot reject heat into air that is already hot, and one in an unheated space can stop cycling altogether because the control never sees a reason to run. Third: common enough on refrigeration generally, but on a cabinet of this size the two above it account for most of what walks in the door.
The order of checks, and why it is this one
- Why this order and not another — Each step below either confirms a cause or removes it, and they are arranged so that the cheapest question is asked first — on a cabinet this size that alone settles most complaints.
- Look at the condenser and at the clearance around the cabinet — Dust on the coil and a tight recess produce the same result, and both are visible without a tool.
- Look for a frost sheet on the freezer rear wall — A solid layer rather than a dusting confirms the airflow cause before anything is dismantled.
- Ask where the cabinet is standing and how warm that room gets — Move it, or accept the limit; there is nothing to repair in this case.
Isolate the machine first
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off.

Where the owner fix stops
Call when the next step would need a meter, and call earlier than that for three things: a breaker that will not stay in, a plug or cord warm to the touch, and oil at any joint in the tubing. Everything above those lines is owner work and most of it needs no tool at all, which is why the order puts it first.
