The short answer for WC models
Warm inside and clearly running is the classic airflow complaint on an Avanti WC refrigerator. The compressor is doing its job and the cold is not reaching the shelves — frost on the evaporator, dust on the condenser, or a fan that has stopped turning. Start with the two you can see and hear before anyone quotes you a sealed system.
What the owner sees
- Frost building on the back wall of the fresh-food section — Within the WC family, humid air getting in past a seal, or a defrost cycle that is no longer clearing what it makes.
- Food safety is already marginal — A refrigerator holds food safely at 40 °F (4 °C) or below; above that the clock has started.
- Warm air blows from the vents instead of cold — On this family, the fan is running and moving room-temperature air, so the evaporator behind it is not cold.
- The compressor runs constantly and never cycles off — On this family, a unit that never rests is working hard for nothing, and that is measurable on the bill before it is obvious in the cabinet.
- NEAR MISS — the unit is silent and nothing is cold — That is a no-power, start-relay or control fault, and it is a different page. If you hear nothing at all, go there instead.
What actually fails on WC models, in order
- A stalled defrost cycle icing the evaporator — It leads on these cabinets because the evaporator sits directly behind the rear panel with very little clearance, so even a thin sheet closes the air path completely.
- A door gasket that no longer seals — Common on undercounter and glass-door cabinets, where the door is opened often and the magnet strip takes a set. That ranking holds across the WC line.
- A thermostat or thermistor reading the cabinet wrongly — Ranked below the mechanical causes because it fails far less often than the airflow path, but it produces the same complaint.
- A sealed-system or compressor fault — Last, and that ordering is the point: it is the least common cause and the only one that is not an owner fix. It is ranked the same way on every WC model.
Check in this order, and why
- Open the door and listen for the circulating fan — On this family, it separates the two likeliest causes before a single tool comes out: air moving means the fan is alive.
- Put a thermometer on a middle shelf and read it after a few hours — A refrigerator holds food safely at 40 °F (4 °C) or below and a freezer at 0 °F (−18 °C) or below — that is the target to judge against.
- Empty the cabinet and leave it off with the door shut — A full manual defrost is a diagnostic, not just a fix: if cold returns afterwards, the defrost system is your fault.
Before you begin
Safety
Isolate the machine at the plug or the breaker before any panel comes off; a capacitor can stay charged after the power is off. Leave the door switch and its wiring exactly as you found them — it cuts the fan for a reason. Refrigerant work is licensed work, so if you find oil at the compressor, stop and hand it over.

When this stops being an owner job
Call once the airflow checks come back clean, or the moment the evidence points at the sealed system: refrigerant is licensed work and the tools are not owner tools. Call immediately if you smell burning, see oil around the compressor, or the breaker trips when the unit starts — oil outside the tubing means the system is open, and every hour it runs after that adds to the bill.
