The short answer for this line
A warm NLD unit is a sequence rather than a single fault. What went into the cabinet and when explains more cooling complaints than any component does, which is why the ranking below departs from the brand-generic order. Start with a warm load or an overfilled cabinet and leave a loss of refrigerant charge until everything cheaper has been excluded.
What this looks like on these models
- It recovers overnight and fails again by afternoon — A pattern that follows the room rather than the machine.
- Cabinet temperature is stable but higher than expected — Steady rather than drifting, which usually means the control is holding it there on purpose.
- The compressor runs constantly and the cabinet stays warm — Never reaches temperature, never stops trying, and the machinery end is hot to the touch.
- NEAR MISS - cold but leaking water — A cabinet that holds temperature and leaves puddles is a drainage fault, and the water leak page for this line covers it.
Causes in likelihood order on this platform
- A warm load or an overfilled cabinet — The leading cause on these models: a cabinet packed to the walls has no room for air to move, and a large warm load takes far longer to pull down than owners expect. Both produce a warm cabinet and a compressor that will not stop.
- An ambient temperature outside what the unit can handle — Second: the unit is not faulty and will behave normally when the room does, but the complaint is real and persists all summer if the position is not changed.
- The condenser unable to shed heat — Third, and worth excluding before going further: a condenser boxed in, dusty or pressed against a wall cannot give up heat, so the compressor runs and runs and the cabinet never reaches temperature. The unit looks healthy and performs like a broken one.
- A loss of refrigerant charge — It ranks last deliberately: every cause above it produces the same warm cabinet for a fraction of the cost.
Check in this order, and why
- Judge the load and then leave it alone — Ask what went in and when. A big warm load the day the complaint started explains the complaint.
- Measure the room, not just the cabinet — Measure the room temperature where the unit actually stands, not in the middle of the house, and look for sun on the case during the day.
- Give the condenser air and a clean grille — Feel the machinery end while it runs: it should be warm. A unit running continuously with a cool condenser has a different problem from one running continuously with a hot one.
Safety first
Safety
Isolate the unit at the plug or the breaker before any panel comes off, because a capacitor can hold a charge after the power is off. If you find oil or a greasy film at the machinery end, stop: that means the sealed system is open and the unit should not be run.

The line between a fix and a call
Stop and call if the compressor never runs at all despite a proven supply, or if it runs continuously with a hot condenser and a cabinet that stays warm. Those two describe the faults that need instruments rather than observation.
