The short answer
Before anything else on the Costway EP refrigerator family, establish whether your model has a factory ice maker at all: the roster in the table gives the model codes but not the feature list, and the plate on your own cabinet is what settles it. If it does not, this page is about the freezer compartment and the trays in it rather than about a module.
What you see on the EP family
- No ice at all and the mould is dry — No water is arriving. That points at the supply line, the valve or a switched-off ice maker rather than at freezing.
- A solid block of ice in the bin instead of cubes — Cubes that partly thawed and refroze, which means the freezer is losing temperature between cycles rather than that the maker has failed.
- Small, hollow or misshapen cubes — Low water flow, usually a partly frozen fill tube or a restricted filter, so each fill is short.
- The maker fills but the cubes never release — Either the compartment is not cold enough to complete a cycle or the mould heater and ejector are not finishing it.
Causes, most likely first on the EP family
- Freezer temperature not low enough to complete a cycle — Ranked first on the EP family — A freezer holds food safely at 0 °F (−18 °C) or below, and a compartment above that will stall the ice cycle before it affects anything else you would notice. An ice maker will not harvest until the mould reaches its release temperature. A compartment running a few degrees warm produces slow ice, then partial ice, then none, with nothing mechanically wrong.
- Ice maker switched off, bail arm up or the bin jammed — Second — and worth ruling out before any part is considered, because it is free. The bail arm or the sensor arm stops the cycle when it reads a full bin, and a bag of frozen food leaning on it reads full forever.
- Water supply, fill tube or filter — Third — it is checkable by eye and it explains a dry mould completely. The supply valve behind the cabinet gets closed during cleaning or a house move, the fill tube freezes shut when the compartment runs cold, and a long-overdue filter throttles the flow.
- Ice maker module, mould heater or the inlet valve — Fourth — it is the expensive end of the list and the one that needs a technician on these models. The module drives the ejector and the mould heater releases the cubes.
- Body: Across a roster this wide the shared parts decide the ranking and the cabinet decides the exceptions, so the top of this list is the failure common to every code in the table rather than the brand-wide average.
Check in this order, and why
- 1. Look into the mould before touching anything — Dry, full of water, or full of a frozen block.
- 2. Check the ice maker is switched on and the arm is down — A bail arm held up by a bag of peas stops the cycle indefinitely, and nothing about the cabinet looks wrong.
- 3. Put a thermometer in the freezer for several hours — A freezer holds food safely at 0 °F (−18 °C) or below, and a compartment above that will stall the harvest before food obviously suffers.
- Body: Across a roster this wide the panel layout is shared but the cabinet is not, so the order below is by access on the chassis and the last step is the one that changes with the model code on your plate.
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. Shut the water supply valve before disturbing any fitting behind the cabinet, and never thaw a frozen fill tube with an open flame or a heat gun: a hair dryer on low or simply switching the unit off is what the job needs.

When to call a technician
The owner line on the Costway EP refrigerator family is everything visible: the arm, the switch, the supply valve, the filter and a thermometer in the compartment. The module, the heater and the valve are service parts, and a frozen fill tube that refreezes within days points at a cabinet problem rather than an ice problem.
