The short answer
On the Arctic Wind ABMP refrigerator a cabinet that is warm while the unit runs is far more often an airflow problem than a dead compressor. The cold is still being made; it is not reaching the food compartment, and two of the checks that separate those two cases need no tools at all.
What you see on the ABMP line
- A sheet of frost across the back wall of the freezer side — Not the usual light dusting but a continuous white skin, often thickest at the bottom.
- The freezer side holds while the fresh-food side does not — Cold is still being made; it is not being delivered, which narrows the fault a long way.
- Food on the top shelf spoils first — Warm air stratifies, so the top of the compartment is where a marginal unit shows itself.
- NEAR MISS - the unit is silent and nothing is cold at all — That is a power, start-relay or control fault and it is a different page; nothing here will help you.
Ranked for the ABMP line
- Thermostat, thermistor or control board reading the compartment wrongly — Most likely here: Electronic controls fail towards a fixed opinion rather than towards silence, which is why a unit with a bad thermistor can run constantly or barely run and both look like a cooling failure. Arctic Wind lists this family beside a long run of other lines sharing the ABM stem and the same numeric cores, so the platform underneath is common to the group and the letter marks the trim or market variant rather than a different machine.
- Iced-over evaporator blocking the air path — Second: The defrost system on a domestic unit stalls long before it fails outright, so frost builds a sheet across the evaporator over weeks and the owner notices the warmth rather than the ice.
- Sealed-system fault: a leak, a restriction or a failed compressor — Third: It is the least common of the causes on this list and the only one that ends the owner's involvement completely, which is exactly why it is checked last and not first.
Check in this order, and why
- First - Note whether the behaviour is stable day to day — A consistent warm cabinet fits a mechanical cause; behaviour that changes without you changing anything fits the control side. That is the order the roster on this page dictates, not a generic sequence.
- Second - Empty the compartment and look at the back wall for a sheet of frost — A solid white sheet rather than a light dusting confirms the air path, and it confirms it before any panel comes off.
- Third - Compare compressor warmth against condenser warmth — Compressor working hard with a cold condenser is the sealed-system signature and the point at which the checks stop.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel - a capacitor can hold a charge after the power is off. The door switch that cuts the fan is a safety device and a diagnostic aid at once: leave it wired as it is. If you defrost with a heat source rather than time and patience you will melt the evaporator tray and the liner behind it, and a punctured evaporator turns a small fault into a sealed-system repair.

When to call a technician
Call once the door, the coil and the defrost checks are all clean, because everything left is read with a meter on live terminals. Call immediately if the compressor is hot while the condenser stays cool, or if you can see oil anywhere around the tubing - oil outside the circuit means the system is open and every further hour of running adds to the bill.
