The short answer
On a Gallery freezer, a compartment that runs without holding temperature is usually an airflow or a sealing fault rather than a failed compressor: a coil under a dust blanket, a gasket that no longer touches, or frost built up until air cannot pass. Each of those is owner-checkable within an hour. A sealed-system fault is the least likely cause here and the only one that needs a licensed technician.
What you actually observe
- The compressor runs almost continuously — It is losing heat as fast as it removes it, which points at the coil or the seal.
- It recovers overnight and drifts up during the day — An ambient or load problem rather than a fault in the machine.
- NEAR MISS: the cabinet is silent and everything has thawed — That is a power or start-relay fault, and it belongs on the page for a unit that will not run.
The causes, most likely first on this brand
- A dust-blanketed condenser coil — The coil has to shed the heat the cabinet removes; insulated by dust it cannot, so the compressor runs continuously and still loses ground. Ranked first on a Gallery freezer: these cabinets are big enough that airflow does all the work, so anything that blocks it shows up as the whole fault.
- Frost built up until air cannot circulate — In a cabinet that does not defrost itself, or one whose defrost has stalled, the ice sheet itself becomes the insulation that stops cooling. Ranked second on a Gallery freezer: this is a high-volume platform where the hardware that cycles daily wears out long before anything exotic does.
- A lid or door that is not sealing — A gasket that has taken a set, or a lid held fractionally open by a packed basket, lets humid room air in continuously and builds frost as it goes. Ranked third on a Gallery freezer: the door hardware is heavy-duty on this platform, so a seal fault usually means a hinge or a level problem behind it.
Check in this order, and why this order
- Look at the coil at the back or under the lower grille — A visible mat of dust and lint there explains the entire symptom.
- Look at the thickness of frost on the walls and on any evaporator you can see — Frost thicker than a coin across the surface is already costing you cooling.
- Close the door on a strip of paper and pull it out at several points — Paper that slides out freely marks exactly where the seal is not touching.
What an owner can safely check
- Unplug the unit and vacuum the condenser coil and its fan grille — Brush along the fins rather than across them so you do not fold them over.
Tools: vacuum, soft brushAbout 20 min
- Empty the cabinet, switch it off and leave it open until every trace of ice is gone — Then reload it and judge over a full day before deciding anything else is wrong.
Tools: towelsAbout 60 min
- STOP HERE once the coil, the seal, the ice and the load are all clean — What remains needs gauges on a sealed system, which is licensed work.
Before you open anything
Safety
Unplug the freezer or switch off its breaker before removing any panel or reaching behind the lower grille — a capacitor can hold a charge after the power is off. A freezer holds food safely at zero degrees Fahrenheit or below, so move anything you intend to keep into another cabinet before you start defrosting. Never chip at ice with a knife or a screwdriver: the evaporator tubing lies directly behind that ice and puncturing it ends the appliance.
When to call a technician
Call once the coil is clean, the gasket seals all the way round, the ice is gone and the cabinet still will not hold temperature — what is left is a control, a fan behind a sealed panel or the sealed system itself. Call at once if you find oil at the compressor or smell burning, and switch the unit off first: a system that is open only gets more expensive the longer it runs.

What this page does not cover
This page covers the Gallery freezer as a class, not one family or model line. Part numbers, wiring colours, torque figures and panel fixings differ from build to build and are deliberately not here. Where a family- or model-specific page exists for your unit, that page is the more specific answer and should be read first.
