A Sub-Zero making noise in Watertown
Noise is the most reported and least specific symptom there is, and the useful first move is to name the sound: a buzz, a click, a gurgle, a rattle and a squeal are five different faults with five different fixes.

Five sounds, five meanings
Most of these are diagnosable from a description, which is why a careful sentence on the phone saves a visit or shortens one.
- A steady low buzz that comes and goes with the compressor: usually normal, unless it has changed pitch or grown louder over weeks.
- A rhythmic click every few minutes: a relay or a defrost timer doing its job, or a compressor trying to start and failing.
- Gurgling and trickling after the cabinet stops: refrigerant settling, and normal. Gurgling constantly is not.
- A rattle that changes when you touch the cabinet: something loose — a drip tray, a grille, a panel, or the cabinet against its run.
- A squeal or a whirring that rises and falls: an evaporator or condenser fan bearing, which is a wearing part and a straightforward replacement.

Why Watertown reports it more
Because of how the housing sits. Two-families and newer condo blocks put a kitchen against a bedroom wall, and a compressor that would be unremarkable in a detached house becomes the reason nobody sleeps. Half the noise calls out here are about an appliance that is working correctly but is audible through a stud wall, and the honest answer to that is not a repair.
The other half are real. A fan bearing that has started to sing will be a stalled fan within a season, and a stalled evaporator fan takes the fresh-food compartment with it.

Safe to check yourself
Pull the base grille and look for a build-up on the condenser. Check the drip tray is seated. Press gently on the cabinet sides while the noise is happening to see whether it changes. If touching the cabinet changes the sound, it is mechanical contact rather than a failing motor — and that is often a five-minute fix.

Water kept collecting under the crisper drawers every few days. He found the drain iced over where it passes behind the rear panel, cleared it, and fitted the little heater clip that stops it recurring.

Cubes were coming off cloudy and half formed. He measured the fill volume and found the inlet valve barely opening. Swapped it, adjusted pressure at the stop, and the very next batch came out clear.

Frost was sheeting right across the back wall of the freezer column. The defrost heater had gone open circuit. He thawed it properly instead of chipping at it, fitted a new heater and sensor, then vacuumed up.
