What this usually means
Warm cabinet, running compressor: start from the idea that the cold is being produced and is not reaching the food. That points first at frost and airflow, second at a fan motor, and only last at refrigerant or the compressor itself. On the LBD line specifically, the platform's layout is what decides which of those gets checked first.
What an owner actually sees on a LBD unit
- Condensation or slick shelves inside — Warm humid air is getting in faster than the unit can pull moisture out of it. This is what an owner of a LBD refrigerator sees first.
- Water pooling under the crisper drawers — Melt from an over-iced evaporator finds the lowest point in the cabinet once the drain is overwhelmed.
- The kitchen has been much warmer than usual — Ambient load matters more than people expect, and a heatwave can push a marginal appliance over the line.
- NEAR MISS: the cabinet is cold but there is water on the floor — A unit that still cools while it leaks is a drain or supply-line problem, not this.
What it usually turns out to be on the LBD line
- Airflow blocked by a frosted evaporator — Ranked first because it builds slowly and quietly: the defrost cycle stalls before it fails outright, ice sheets over the coil for weeks, and the owner notices the warmth long before the frost. The LBD build does not move this one: its rank is the same here as on the brand-generic page.
- A damper or diffuser stuck shut between the compartments — The classic cause when the freezer is fine and the fresh-food side is not: cold is made and then not let through.
- A thermistor or temperature sensor reading the cabinet wrongly — The control believes the cabinet is colder than it is and stops asking for cooling. It is uncommon and it is diagnosed after the visible causes.
- A sealed-system or compressor fault — Last, and that ranking is the point of this page: it is the least likely cause on the list and the only one that is not an owner check. Anyone naming it first has skipped every cheaper answer above it.
The order that narrows it
- Open the freezer and listen for the circulating fan — It separates the two likeliest causes before a single tool comes out: a fan you can hear rules out the stopped-motor branch. The LBD layout is the reason it comes first here.
- Watch whether the compressor ever stops — Continuous running with no cycling means the unit is never reaching its set point, which narrows the list to heat rejection and airflow.
- Hold a hand in front of the fresh-food vent for a minute — Cold air arriving proves the damper and the duct; no air narrows the list to the fan and the ice.
Before you open anything
Safety
Isolate the appliance at the plug or the breaker before starting, and keep it isolated. Leave the door switch and its wiring exactly as the factory built them. Never chip ice off an evaporator with a metal tool: the tubing sits directly behind that surface.

Where the owner side ends
Owner territory ends at the first panel. Call for anything behind one, and call immediately if the appliance trips its breaker or you can smell anything hot at the back of it.
