The short answer
The usual answer on this unit is a frosted-over evaporator and a stalled defrost cycle; a failed or obstructed evaporator fan is the runner-up. Both of those are cheap. The sealed system is last on the list for a reason. You can settle most of this yourself before anyone comes out, and this page stops where the meter starts.
The symptoms, and their near misses
- The freezer is cold but the fresh-food side is not — Cold is being made and not delivered, which points at airflow and not at cooling.
- NEAR MISS: it cools but leaks water onto the floor — That is a drain fault. Read the water-leak page for this unit instead.
What it usually turns out to be, in order
- A frosted-over evaporator and a stalled defrost cycle — Ice builds on the evaporator until air can no longer pass through it. The unit keeps running and keeps making cold, but none of it reaches the cabinet. First, and the whole order below follows from it: the defrost system stalls long before it fails outright, so the ice builds quietly over weeks and what the owner notices is the warmth, never the frost.
- A failed or obstructed evaporator fan — The fan behind the freezer rear panel is what pushes cold air into the fresh-food side. Second: it is the one motor in the cabinet that runs almost continuously, and it is the part that gives out first on most platforms.
- A sealed-system or compressor fault — A refrigerant leak or a failing compressor gives the same warm cabinet as everything above it, which is exactly why it is diagnosed last and not first. Last, and that is the point of this order: it is the least common cause on this list and the only one that is not an owner fix, so checking it first only ever wastes money.
Check in this order, and why
- Look at the freezer rear panel for a sheet of frost — This separates an airflow fault from a cooling fault before any tool comes out.
- Open the freezer and listen for the fan, then press the door switch in by hand — If the fan does not start when the switch is held in, you have found it.
- Feel whether the condenser coil is warm along its length — Only worth doing once everything above is clean, and only a technician can act on it.
The checks you can make yourself
- Empty the freezer, switch the unit off at the wall and leave both doors open until it is fully thawed — If cold returns afterwards and then fades again over days, the defrost system is your cause.
About 45 min
- Hold the freezer door switch in and listen for the fan behind the rear panel — No fan noise with the switch held in points straight at the fan or its switch.
About 5 min
- STOP AT THIS POINT if the fault is on the sealed system — Refrigerant is licensed work and the tools for it are not owner tools.

Safety
Pull the plug or drop the breaker before you take off a panel. There is a capacitor in this appliance that stays charged after the power is gone, and the compressor terminals are live whenever it is not. Do not rewire or bypass a door switch to keep a fan running while you look. Refrigerant work is licensed, so the sealed system is a technician's job from the first step to the last.
When to call a technician
Call once the checks above come back clean, or the moment the fault is on the sealed system: refrigerant is licensed work and the tools for it are not owner tools. Call sooner if you smell burning, see oil around the compressor, or the unit trips a breaker.

What is deliberately not on this page
This page covers the WERCS refrigerator as a class, not one family or model line. Where a family- or model-specific page exists it is linked here. Deliberately not here: wiring colours, board part numbers, refrigerant charge figures and any sealed-system procedure, all of which differ by family and belong on the page for that family.
