The short answer
A compact Absocold that drifts warm is usually iced up or short of air: nothing clears the cold plate but you, and an enclosure without ventilation traps the heat the rear coil is trying to shed. The thermostat dial is worth checking first because it costs nothing. All three are owner-side. A unit that clicks without running has a start-relay problem and needs a technician.
What you observe
- A thick ice layer on the cold plate — On a manual-defrost unit this is the fault itself.
- The unit runs constantly and never satisfies — Ice, a poor seal or a hot enclosure.
- The rear of the cabinet is very hot to the touch — The coil cannot shed heat into a sealed enclosure.
- The thermostat dial is at a different setting than you remember — Free to correct, and it happens more than people expect.
- NEAR MISS — it clicks every few minutes and never runs — Start relay or compressor. A service call.
Causes, most likely first on this class
- Ice build-up on the manual-defrost cold plate — First because there is no defrost system to fail: the ice simply accumulates until it insulates the plate from the compartment air. Owners used to frost-free machines rarely expect it.
- Enclosure with no ventilation at the rear coil — Second, and specific to built-in hospitality units. The coil is trying to dump heat into a sealed cupboard, so the cabinet can never get ahead.
- Thermostat dial moved, or the door not sealing — Third: both are free to correct and both look exactly like a failure. A dial knocked by a shelf is a real and frequent cause here.
- Start relay, overload or compressor fault — Last, and the only one that is not owner work. Its signature is a click every few minutes with no sustained running.
Check in this order, and why
- Look at the thermostat dial setting — Free, instant, and a genuine cause on this class.
- Look at the thickness of ice on the cold plate — On a manual unit this is the answer more often than not.
- Feel the rear of the cabinet and check the enclosure — Very hot with no airflow explains everything at once.
- Test the door gasket with a sheet of paper — Left until here, but it explains why the ice returns fast.
What an owner can safely check
- Set the thermostat to a mid or colder setting and wait a day — Judge it after a full day, not after an hour.
About 5 min
- Empty the unit and defrost it fully with the door open — Let the ice melt. Do not chip at it. Mop as it goes.
Tools: cooler, towelsAbout 90 min
- Open the enclosure or leave the cupboard door ajar and retest — If cooling improves, the installation needs ventilation.
About 30 min
- Test the gasket with paper at several points — Where it slides free, the seal is gone.
Tools: sheet of paperAbout 10 min
- STOP HERE if it clicks without running — Start relay and compressor testing needs a meter.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel or reaching behind it; a capacitor can hold a charge after the power is off, and the start relay sits beside the compressor. Never chip ice off a cold plate with a knife or screwdriver — the plate is thin-walled, and piercing it releases refrigerant and ends the unit's life. Let the ice melt. Dry the floor before restoring power, and get help drawing a built-in cabinet out of furniture.
When to call a technician
Call when the unit has been fully defrosted, the enclosure has been opened up, the dial is set correctly and the gasket grips, and it still will not hold temperature. Call sooner if it clicks every few minutes without running. Call immediately if you smell burning or see oil around the compressor — oil outside the tubing means the sealed system is open and the unit should be unplugged.

What this page does not cover
This page is written for the brand and the appliance class, not for one family or model line. Where a family- or model-specific page exists for your unit, that page is the more specific answer and you should start there. Deliberately absent: climate-class ratings, clearance and cut-out dimensions, thermostat calibration figures and part identifiers, all of which differ between the freestanding, built-in and hospitality-unit families.
