Common fault
Why is there water under my refrigerator?
Short answer
Water under a built-in has two realistic sources and both are small repairs that get expensive by being left.
Why we start there
One is the defrost drain: it has plugged with ice, the melt has nowhere to go, the trough inside the cabinet fills, and the overflow finds its way out past the door. The other is the water line feeding the ice maker, which has let go at a joint. Clear water turning up quickly at the front points at the plumbing. Cloudy water arriving slowly, with ice across the freezer floor, points at the drain. In Poway there is a useful extra clue: in a hot dry summer the evaporation tray normally keeps up with ordinary defrost melt, so standing water on the floor in August is telling you something is arriving that should not be.
What happens next
Older Poway kitchens carry a particular version of this fault. Plenty of these houses were built before an ice maker was standard, and the water line was added later, tapped into the nearest copper with a saddle valve and run behind the cabinets or up through the slab. Saddle valves weep. That is not an opinion about the installer, it is what that fitting does after a decade or two, and the leak is slow, hidden behind a built-in that weighs several hundred pounds, and going somewhere you cannot see. If your unit is a retrofit into an older kitchen, the connection at the wall gets checked under pressure on the visit whether or not it looks dry at rest, because a weeping fitting looks perfectly fine until it is loaded.
The garage version is the one that goes unnoticed longest. A refrigerator leaking onto a garage slab produces no dramatic evidence at all. The water runs out flat, some of it evaporates, and the rest sits under the unit and wicks up into the base of the drywall or the back of a cabinet where nobody is looking. What people eventually notice is a stain or a soft patch on a wall, months after the leak started. If you have found a chalky mineral outline on the slab under a second refrigerator with no water visible anywhere, that is still an active leak and it is still worth a call.
If that matches what yours is doing, say so when you call — it decides which parts come on the van.
Our wine cooler had fluctuating temperatures. The technician identified and replaced a faulty sensor during a same-day visit. Efficient, knowledgeable, and reliable service in the Poway Heritage area.
The fresh food side kept climbing every afternoon while the freezer sat there rock hard, so I had myself convinced it was the compressor and a whole new unit. He pulled the grille, showed me the coil furred with granite dust, and pointed at the soffit our Green Valley remodel dropped over it.
Our garage refrigerator kept letting the freezer go soft on cold mornings while the fridge side read perfectly fine. Two other outfits wanted to sell me a control board. This guy talked me out of it on the phone, then came out and dealt with the actual problem.

Questions
Answers before you call
Does a built-in have to come out of the cabinetry to be worked on?
Almost never. It is built to be serviced where it stands: the condenser is reached through the grille at floor level and both sealed systems are laid out for access from the front. Pulling one out risks the cabinetry, the flooring and, on a panel-ready column, a custom front worth more than the repair. If one genuinely must be moved, you hear why first.
