The short answer
On a two-door compact the freezer plate above and the fresh-food box below share one drip path, and packing is what closes it. Ranked first on this platform: Condensation on a cold plate or rear wall. The checks below follow that ranking, and the first of them need no tools and no panel removed.
What you observe
- Water pooling at the bottom of the rear wall inside the cabinet — The pool sits directly below the surface that made it.
- The wet patch inside arrives in bursts rather than steadily — Bursts mean an accumulation is being released, not a leak running.
- Water at the door line, with condensation or frost around the same part of the seal — The wet patch marks where the air is coming in.
- NEAR MISS — water only appears after a power cut or a long door-open — That is melt from the evaporator finding its way out, and it usually needs no repair at all.
Causes, most likely first on this platform
- Condensation on a cold plate or rear wall — A static-cooled cabinet frosts its rear plate during the run and melts it during the off cycle by design. It ranks first on this platform because a package pressed against the plate holds it below freezing through the rest period, so the frost that should have melted and drained stays and grows — then releases all at once, which is why this leak arrives in bursts.
- Food packed against the cold surface — Anything pressed against a cold plate or a rear vent keeps that surface below freezing through the off cycle. It ranks second here because the fresh-food section is cooled by spill-over from the freezer plate through a small port, so anything that blocks that port warms the lower box while the upper one still freezes.
- Humid air entering past a door seal — A seal that is not sealing lets room air in continuously. That air is humid, it meets a cold surface immediately, and the water it drops runs down inside the liner and out under the door. It ranks third rather than higher: real on this platform, and less common than the causes above it.
Check in this order, and why
- Look at the channel at the foot of the rear plate and the hole in the middle of it — The hole is the narrowest part of the whole system and the first thing to check. It leads because it tests the top-ranked cause.
- Look at what is touching the rear wall of the cabinet — A single package against the plate is enough to do this. Tests the second-ranked cause.
- Run a slip of paper round the door seal and note where it pulls out freely — It maps the failure round the whole door in a couple of minutes. Tests the third-ranked cause.
What an owner can safely check
- Clear the channel and the hole with warm water and a soft flexible line — Keep food a hand-width off the rear plate afterwards so the melt can run.
Tools: warm waterAbout 25 min
- Pull everything a hand-width clear of the rear wall and keep it that way — Do this before defrosting, or the same cause simply repeats.
About 15 min
- STOP before anything behind a fixed panel, and note what each check showed — Everything past this line is measured rather than looked at, and measuring it safely needs the power off and a meter.
Before you start tracing it
Safety
Unplug the appliance or switch off its breaker before removing any panel or reaching into the base — a capacitor can hold a charge after the power is off, and water plus a live compartment is the one combination to take seriously.
When to call a technician
Call once the water is coming from behind a sealed panel, from the sealed system, or from a drain that will not clear from the cabinet side.

What this page does not cover
This page is written for the MircoChill refrigerator as a class, not for one family or one model line. Where a family- or model-specific page exists for your unit, that page is the more specific answer and the one to read first. Deliberately not here: part numbers, wiring colours and disassembly order, which differ by family.
