The short answer for the NPGB models
On the Alcove NPGB refrigerator models, water appearing inside the cabinet or on the floor beneath it leads with condensation from a door that is not sealing rather than with the cause the brand-generic article opens on. The spine for the NPGB family records a single model code, so this is one cabinet rather than a platform run, and everything below is written for that one build.
What you observe on these models
- Water appears even when the cabinet is switched off — Only the supply keeps running with the power off, so that narrows it to one cause immediately.
- A puddle on the floor at the front of the cabinet — It has run forward from the base, which is what happens once the interior has filled.
- The puddle appears on a rhythm, every few hours — That rhythm is the defrost cycle, and it is close to a diagnosis on its own.
- NEAR MISS — water plus a cabinet that is no longer cold — Deal with the cooling complaint first; that page covers it and this one does not.
Causes, most likely first on the NPGB family
- Condensation from a door that is not sealing — A seal that has hardened lets air in all day, and the result collects at the bottom of the compartment where it looks like a leak. Ranked first here.
- A cabinet leaning the wrong way — This is free to check and free to correct, and it explains more interior water than most people expect. Second.
- A cracked drain pan or an internal line — A split moulding or a damaged internal line. Last, and that is the point of the order: it is the least likely here and the only one that is not owner work.
- Body: The cause that moves up on these models is condensation from a door that is not sealing; what moves down to make room for it is a blocked defrost drain, which is where the brand-generic article for this symptom opens.
Check in this order, and why
- Close the door on a strip of paper at several points along the seal — First: Anywhere it slides free, damp air is entering and condensing inside.
- Check whether the cabinet leans forward on its feet — Second: Interior water runs to the drain only if the cabinet is sitting the way it was designed to.
- Note whether the puddle returns on a schedule or arrives continuously — Third: A rhythm points at defrost; a steady arrival points at supply.

Safety
Nothing comes off this cabinet until it is unplugged or its breaker is switched off — a capacitor holds a charge after the power is gone, and a fan inside can start without warning. Never defeat a door switch to keep a fan running while you look: it is there to stop a blade turning next to your hand. A refrigerator holds food safely at 40 degrees Fahrenheit, 4 degrees Celsius, or below.

When to call a technician
Call when the checks above have been done and the fault is still there, or as soon as the evidence points at a cracked drain pan or an internal line — that is the one cause here that is not owner work. Call immediately, and unplug the cabinet first, if you smell burning, see oil around the compressor, or hear a hiss with a sharp smell.
