The short answer
On an ACOPOWER refrigerator, not cooling or not freezing most often comes back to a supply that sags under compressor start current, with a blocked or fouled condenser, or no clearance to reject heat close behind. There is no defrost system, no ice maker and no plumbed water anywhere in the cabinet, so several classic refrigerator faults simply cannot happen here — and knowing that removes most of the list before you start. That puts the first move in your hands rather than a technician’s: work the checks below in order and stop at the first one that explains what you are seeing.
What you are seeing
- What this fault looks like, and which observations point somewhere else.
- the back wall of the fresh-food section is either heavily frosted or completely dry and warm to the touch
- condensation appears on the inside of the liner as the cabinet loses its temperature difference
- the fresh-food section is warm while the freezer still feels cold, or both sections are drifting up together
- Not this fault: if the cabinet is silent and the interior light is out, this is a supply fault, not a cooling fault
Ranked causes on this platform
- Ranked for an ACOPOWER refrigerator, which runs a DC compressor controller with a low-voltage cut-out setting and a set-point display. No measured frequency exists for this address, so the order is platform judgement rather than a share.
- A supply that sags under compressor start current — Why: The controller protects the battery rather than the contents, so a marginal supply produces short runs and a slowly warming cabinet.
- A blocked or fouled condenser, or no clearance to reject heat — Why: Every other component can be perfect and the cabinet will still fail to hold temperature if the heat has nowhere to go.
- A room the cabinet cannot reject heat into — Why: A cabinet in a hot garage, a closed alcove or full sun runs continuously and still loses ground, and no repair will change that.
- An evaporator iced over because the defrost cycle is not clearing it — Why: A blocked evaporator starves the cabinet of cold air while the compressor keeps running, which is why this fault always looks like a failing compressor first.
What to check, in order
- The order follows the ranking above: most likely and cheapest first, nothing needing a meter until everything else is eliminated.
- A supply that sags under compressor start current — Because: the controller protects the battery rather than the contents, so a marginal supply produces short runs and a slowly warming cabinet.
- A blocked or fouled condenser, or no clearance to reject heat — Because: every other component can be perfect and the cabinet will still fail to hold temperature if the heat has nowhere to go.
Checks you can safely do yourself
- Isolate the appliance before any panel comes off, and stop at the first step that explains the fault.
- Swap to the mains adapter for a day and see whether the cabinet holds its set point. — Tools: the mains adapter — Time estimate: leave it overnight
- Clear the grille and the coil, and give the cabinet clear air on the sides and behind before changing anything. — Tools: a coil brush and a vacuum — Time estimate: a quarter of an hour
- Note the room temperature and the clearances before condemning any part. — Tools: nothing — Time estimate: a few minutes
- Stop condition: Stop there: the next step means metering live terminals or opening a sealed system.
Safety first
Safety
Unplug the appliance or switch off its breaker before removing any panel, because a capacitor can hold a charge after the power is off. Never open a sealed refrigeration circuit; refrigerant work is licensed work and a punctured line ends the life of the cabinet. A loaded cabinet is heavy and top-sided — move it with two people and empty the door first.
When to call a technician
Call a technician when the cabinet still will not hold temperature after the airflow, seal and control checks are clean, when the evaporator ices up again within days of being cleared, or when the compressor is hot and silent rather than running. Sealed-system work is licensed work and is not an owner repair under any circumstances.

What this page does not cover
This page is generalized across every ACOPOWER refrigerator family and model number: no family fault list, no model parts list, and no measured figure from the program warehouse. Where a family- or model-specific page exists it goes deeper, and it should be preferred over this one.
