The short answer
This page covers the Bodega Cooler M-series refrigerator, the models whose number carries the M prefix. Most coolers in this class have no ice maker at all, so on a Bodega Cooler cabinet the phrase usually describes the opposite problem: ice forming where it should not, on the cooling plate at the back of the cabinet. Where a model does have an ice maker, the checks are the ordinary water-supply ones.
What you observe on these models
- A sheet of frost or a slab of ice on the rear interior wall — The cooling surface icing over. It insulates itself as it grows, which is why the cabinet gets warmer as the ice gets thicker.
- Bottles at the back freezing while the front stays cool — Contact with an over-cold plate, not a temperature fault across the cabinet.
- The unit runs constantly and the frost keeps growing — Frost thick enough to block airflow makes the unit run longer, which makes more frost - the loop these cabinets fall into.
- NEAR MISS - your model has an ice maker and the tray is empty — Then this is a water-supply question, not a frost question: check the shutoff, the line, the valve screen and the freezer temperature instead.
Causes, most likely first on this family
- A glass door that no longer seals — First, and the mechanism behind most persistent frost: a distorted magnetic strip or a door held off by an overloaded shelf feeds the plate damp air all day.
- Humid room air getting into the cabinet — Second. Every door opening in a damp room deposits moisture on the coldest surface, and in a small cabinet that surface is the plate.
- A blocked drain hole at the base of the rear wall — Third. The channel that should carry melt to the evaporation tray silts up, the water backs into the cabinet and refreezes at the next cycle.
- A thermostat set colder than the contents need — Fourth. Turned to its coldest, the plate runs below freezing continuously and condenses everything it meets into ice.
- A failed thermostat, sensor or fan — Last. A plate that never stops cooling because the control never opens is a real fault, but it is diagnosed once the four environmental causes above are out of the way.
- Where this ranking departs from the brand-generic page — The cause that moves is a glass door that no longer seals: it leads here because the door on these models carries the seal along a slim frame that distorts if the cabinet is not level, so the seal is established first and the room second.
Check in this order, and why
- Close the door on a strip of paper at several points around the frame — On these models the door on these models carries the seal along a slim frame that distorts if the cabinet is not level, so the seal is established first and the room second, which is why this check leads.
- Find the drain hole at the base of the rear wall and clear it — A cotton bud and warm water. Blocked, it turns every defrost into a puddle and then into new ice.
- Notice the room: damp, warm, a lot of traffic at the door? — Frost is water that arrived from somewhere. In a small cabinet the room is nearly always where it came from.
- Turn the thermostat to a middle setting and give it a day — Colder is not better here. The coldest setting is what keeps the plate below freezing around the clock.
Before you open anything
Safety
Unplug the cooler before defrosting it or touching anything behind a panel - a capacitor can hold a charge after the power is off. Never chip, scrape or pry ice off the cooling plate: it is thin-walled and it holds the refrigerant.
When to call a technician
Call when a full defrost, a clear drain, a sealing door and a moderate setting still leave you with ice returning within days - that pattern points at a thermostat or sensor that never opens, which is metered live. Weigh the call against the unit, though: on a compact cooler a control repair is worth doing and a sealed-system repair usually is not.
