What this means on these models
On the AZC freezer this symptom is usually the defrost circuit, because on a frost-free cabinet a stalled defrost buries the evaporator in ice and stops the air moving. The AZC family spans more than one size or configuration code, and those differences change the parts rather than the order of the checks. That is where this page departs from the brand-generic article: the checks below are ordered for these models rather than for everything the brand sells.
What you observe on these models
- A repeated click from the compressor every few minutes — The start relay pattern, and the compressor is probably fine.
- The problem started after a big shop or a hot spell — A warm load or a hot room, both of which need days rather than a repair.
- The alarm sounds but everything looks normal — Worth believing: the cabinet has measured something the lid does not show.
- The cabinet runs constantly and never reaches temperature — Continuous running is the machine trying, which rules out most control faults.
- NEAR MISS — the cabinet is silent with no lights at all — A dead cabinet with no lights is a supply or board fault rather than a cooling fault, and it is checked at the socket first.
Causes, most likely first on the AZC family
- Defrost system stalled on a frost-free cabinet — Ranked first on this family. A manual-defrost cabinet cannot fail this way, which is the first thing to establish before spending any time here.
- Start relay or overload at the compressor — Next, and close behind it. A failed relay gives a click, a pause and another click, with the compressor never running and the cabinet slowly warming.
- Control board or the compressor never being commanded — Next after those two. It is below the cheaper causes because it needs testing rather than observing.
- Overloaded cabinet, warm load or a hot location — Fourth, and the least likely of the four. A large warm load takes days to pull down, and during that time every reading looks like a failure.
- Body: A brand-generic article on this symptom starts with the lid or door seal. Here the defrost system moves ahead of it, because the size codes in this family share a subsystem, and that shared subsystem is where the failures concentrate.
What to check first, and why that order
- Establish whether the cabinet is frost-free or manual defrost, then look at the coil — A thick even sheet across a frost-free evaporator is the fault; on a manual cabinet, heavy frost is simply a defrost overdue.
- Listen at the compressor for a repeated click with no sustained run — Click, hum, silence, repeat is the relay pattern, and it is worth a visit before anything drastic is decided.
- Note whether the compressor ever starts at all over several hours — A compressor that never starts while the cabinet is plainly warm is the point at which this stops being an owner job.
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. A freezer holds food safely at 0 degrees Fahrenheit, which is minus 18 Celsius, or below; food that has thawed should be judged on that basis and not on how it looks. Nothing on the sealed side is owner work, and a loaded chest cabinet is far too heavy to move without help.

When this becomes a service call
Call immediately for oil at the compressor, a burning smell or scorching at a connector. Call once the seal, the clearance, the coil and the thermometer check are all clean and the cabinet still will not hold.
