What this usually turns out to be
Warm inside with the compressor running points at a defrost or airflow fault far more often than at a dead compressor. Work the cheap, decisive checks first: they tell you whether this is an afternoon of cleaning or a technician visit. The LRD key on the rating plate groups models that share their airflow layout, so the access route below holds across the family even where capacities differ.
How this shows up
- The compressor runs and never cycles off — It is chasing a temperature it cannot reach, so it never gets the signal to stop.
- Warm air blowing from the grille at the bottom or back — Warm air at the grille is the machine shedding heat, which is what it should do. What matters is whether the cabinet is getting the benefit.
- Condensation or sweating on the inside walls — Warm, moist air is getting in and is not being removed, which usually rides along with one of the causes below.
- NEAR MISS — The unit is silent and nothing is cold at all — Nothing at all — no hum, no fan, no interior light — is a different fault with a different page. Check the socket and the breaker before anything else.
What is behind it, ranked
- A dirty condenser coil or a stopped condenser fan — This is the cause that punishes a refrigerator in a tight cabinet or against a wall: restricted airflow at the coil means the compressor runs long and the cabinet never catches up. This ranks first on the LRD models because the rest of the order only makes sense once it has been cleared. This is where the LRD order departs from the brand-wide one: a dirty condenser coil or a stopped condenser fan moves ahead of a door that is not sealing, or is being opened too often because on this platform it is the faster of the two to confirm.
- A stalled defrost cycle icing over the evaporator — When defrost stops running, frost builds on the evaporator until air can no longer pass through it. The cabinet warms while the compressor runs harder than ever, which is exactly the symptom on this page.
- A failed or blocked evaporator fan — Fan failure on a refrigerator is usually audible or, more precisely, its absence is: open the freezer with the door switch held and the noise that should be there is not.
The order the checks belong in
- First — look at the condenser coil and feel the airflow — The coil is where heat is supposed to leave. If you cannot see metal through the dust, nothing else on this list is worth checking until it is clean. Each step is chosen to split the remaining causes roughly in half, which is why doing them out of order costs you time rather than saving it.
- Second — look at the freezer rear panel for a frost sheet — Empty the freezer far enough to see the back wall. A solid white sheet rather than a light dusting tells you the defrost system has stopped and everything else on the list is a symptom of it.
- Third — listen at the open freezer for the evaporator fan — The fan should be audible the moment the door switch is held. Its silence is worth more than any other single observation on a cabinet that is cold in one half and warm in the other.
Safety first
Safety
Disconnect the power before you open anything. Leave the door switch wired as it is; it cuts the fan for a reason, and holding it closed with tape while you reach inside is how fingers meet a moving blade. Melt frost with time or a hairdryer on a low setting held well back, never with a sharp tool.
When to call a technician
The line is the panel: anything you can reach without a meter and without removing a cover over the sealed system is yours, and everything past it is not. If the defrost system is the confirmed cause, that is a technician job too — the heater and the sensor behind that rear panel are tested live.
