Start here
When a WH unit stops cooling, the useful split is whether it makes no cold at all or makes cold it cannot distribute. Prove what is reaching the unit before you judge the unit, because a supply that sags looks exactly like a dead compressor, and that distinction decides everything that follows. Start with a marginal supply or lead and leave a loss of refrigerant charge until everything cheaper has been excluded.
The observables
- Cabinet temperature is stable but higher than expected — Steady rather than drifting, which usually means the control is holding it there on purpose.
- The compressor runs constantly and the cabinet stays warm — Never reaches temperature, never stops trying, and the machinery end is hot to the touch.
- It runs for a few minutes, stops, and starts again — The same short cycle repeated all day, with the cabinet never coming down.
- Cold at the plate, warm at the far end of the cabinet — Cooling is being made but not distributed, which points at air rather than at the system.
- NEAR MISS - cold enough but noisy — Noise with normal temperatures is a mounting or contact problem, not a cooling problem, and it has its own page.
Causes, most likely first on this line
- A marginal supply or lead — It ranks first on this line because it is free to exclude and because it produces the two complaints that look most like a dead compressor.
- A frosted plate blocking airflow — Second: the frost is a consequence of humid air getting in, so this cause usually sits downstream of a seal or a door problem and returns if only the ice is dealt with.
- The condenser unable to shed heat — Third, and worth excluding before going further: a condenser boxed in, dusty or pressed against a wall cannot give up heat, so the compressor runs and runs and the cabinet never reaches temperature. The unit looks healthy and performs like a broken one.
- A loss of refrigerant charge — It ranks last deliberately: every cause above it produces the same warm cabinet for a fraction of the cost.
The order to work in
- Prove the supply before anything else — Run the unit from a different socket on a different circuit, using its own lead and no adaptor. A unit that cools normally there had a supply problem, not a fault.
- Look at the plate before concluding anything — Note where the frost is heaviest, since that is where the warm air is arriving.
- Give the condenser air and a clean grille — Pull the unit a hand-width clear on every side, brush the grille and the coil clean with the unit isolated, and give it a few hours. A cabinet that recovers had a heat problem.
Before any panel comes off
Safety
Unplug the appliance or switch off its breaker before removing any panel - a capacitor can hold a charge after the power is off. Do not defeat a door switch to keep the cabinet running with the door open while you test; use a thermometer instead.

When this stops being owner work
Everything reachable without a panel is owner work. Repeated failed starts, a fan motor, a sensor disagreement or anything on the sealed system is not, because those need measurement and refrigerant work is licensed work.
