The short answer
A freezer that is running and still warm is failing to move heat out, and the causes divide neatly into things around the cabinet and things inside the sealed system. This is a compact freezer or small refrigeration unit of the kind sold for a garage, a basement or a second kitchen, and it is a simple machine: most units of this class have a mechanical thermostat, a manual-defrost evaporator and no defrost timer at all, so frost and door sealing rank far above electronics. That is why "frost slab on the evaporator" heads the ranking on this page, while "sealed system losing capacity" sits at the bottom of it.
What you are actually seeing
- Ice cream is soft and packaged food has lost its firmness
- A thermometer in the middle of the load reads above the safe holding temperature
- The unit runs continuously and never cycles off
- Frost has become soft and wet rather than dry and powdery
- Food at the top of a chest cabinet is thawing while the bottom is still frozen
- Not this fault: the cabinet is silent and shows no sign of running — Means: a power or control fault rather than a cooling fault — See: brada-freezer-control-fault
- Not this fault: water is running out onto the floor — Means: a drain or thaw fault — See: brada-freezer-water-leak
Likely causes, most likely first
- Frost slab on the evaporator — Why here: a thick frost layer insulates the very surface that is supposed to absorb heat, and on a manual-defrost cabinet it is the expected answer rather than an exception — Confirmed by: frost thicker than a coin over the evaporator surface or the inner walls
- Lid or door not sealing — Why here: a continuous humidity and heat load that explains both the warm cabinet and the frost that caused it — Confirmed by: condensation at the frame, a gasket that fails a paper test, or a lid resting on a package
- Ambient temperature around the cabinet outside its rated range — Why here: first because garages, porches and unheated basements are where these cabinets live, and a unit that cannot see enough temperature difference simply stops performing — Confirmed by: the failure follows the weather, and the cabinet performs again when the room does
- Overloaded, or loaded with warm food — Why here: ranks here because it is temporary and self-inflicted, but it produces a genuine and alarming warm reading — Confirmed by: the problem started the day a large warm load went in and is easing day by day
- Condenser coil or the space around the cabinet choked — Why here: the highest-yield owner fix on any cabinet that runs constantly and stays warm — Confirmed by: dust on the coil or the back panel, no clearance behind or above the unit, and a hot machine compartment
Check in this order
- Read a thermometer placed in the middle of the load, not at the top — Because: a freezer holds food safely at 0 °F (−18 °C) or below, and a reading at the top of a chest cabinet is always the warmest point
- Check the room the cabinet is standing in — Because: ambient conditions explain most seasonal freezer complaints and no part will fix them
- Check the clearance and the condenser — Because: a cabinet that cannot reject heat cannot freeze, and this is the free fix
- Measure the frost thickness on the evaporator or the inner walls — Because: it decides whether the answer is a defrost or a service call
Owner checks, in order
- Put a thermometer in the middle of the load, close the cabinet, and read it later — the target is 0 °F (−18 °C) or below — Tools: a freezer thermometer — Time: several hours, unattended
- Note the room temperature where the cabinet stands and compare it with the range on the data plate — Tools: a room thermometer — Time: a few minutes
- Unplug the unit and clear the clearance around and behind it, then vacuum the condenser coil and grille — Tools: a vacuum, a coil brush — Time: roughly half an hour
- Check the frost thickness on the walls or the evaporator, and if it is more than a thin film, empty the cabinet and defrost it fully — Tools: a cooler, towels — Time: overnight
- Restore power, reload once the cabinet is cold again, and re-read the thermometer after a full day — Tools: a thermometer — Time: a day
- Stop condition: Stop before any test that would put a meter on live terminals.
Safety before you start
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. A loaded freezer is extremely heavy. Empty it before moving it, and never tip a cabinet on your own. The sealed refrigerant circuit is not owner-serviceable. Do not cut, bend or braze any tube.
When to call a technician
the cabinet will not reach the safe holding temperature after a full defrost and a clean coil it runs continuously with a condenser that never gets hot frost returns within days of a complete defrost
a value marque with a thin parts channel; a mechanical thermostat or a gasket is usually obtainable, a sealed-system repair rarely worth it
