Start here
When a Y unit stops cooling, the useful split is whether it makes no cold at all or makes cold it cannot distribute. When the plate carries a sheet of ice the unit is insulated from its own cooling, and everything else is downstream of that, and that distinction decides everything that follows.
The observables
- 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.
- A hum or a click every few minutes and no sustained run — Something attempts to start and drops out, and the machinery end never warms.
- 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 frosted plate blocking airflow — Ranked first on this line: once the cold plate carries a sheet of frost, the cabinet is insulated from its own cooling. The compressor runs, the plate gets colder, and the air in the cabinet does not, so the unit fails while doing everything right.
- A marginal supply or lead — Next, and close behind: a compressor draws its heaviest current at the moment it starts, and a supply that sags under that load leaves the unit clicking or running without ever pulling down. The cabinet stays warm while everything looks alive.
- A door or lid that is not sealing — Then: on a compact cabinet the ratio of door to volume is large, so a leak that would be tolerable on a full-size refrigerator is decisive here.
- A loss of refrigerant charge — Last, and the reason the order matters: a system that has lost its charge runs continuously, stays quiet, and produces little or no cold at the plate. It is the least likely cause and the only one that decides whether the unit is worth keeping.
The order to work in
- Look at the plate before concluding anything — Look for a sheet rather than a dusting. If it is a sheet, defrost the unit fully with the door open and run it again; recovery confirms airflow was the problem.
- Prove the supply before anything else — Note whether the unit clicks and stops, or runs continuously. Clicking and stopping points at supply or start; running continuously points at airflow.
- Test the seal at several points — Close the door on a strip of paper at the top, the middle and the bottom of each side and pull. Anywhere it slides out freely is a leak, and the coldest part of the cabinet will be furthest from it.
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
Call once the supply, the clearance, the seal, the setting, the load and the frost are all clean and the cabinet still makes no cold: what is left is the machinery. Call immediately if you find oil at the machinery end, or if a breaker trips when the unit starts.
