The short answer
A Cosmo COSSBSR Refrigerator that has stopped producing ice is worth checking in supply order — is there water, is the compartment cold enough, is the ice maker switched on and unobstructed — because that is the order from free to expensive. Start at the module and you will usually replace a working part.
What you see on the COSSBSR 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 COSSBSR family
- Freezer temperature not low enough to complete a cycle — Ranked first on the COSSBSR 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 this model. The module drives the ejector and the mould heater releases the cubes. A failed valve will not open on demand even with good supply pressure.
- Body: The order below is this family's rather than the brand's: with one build in the COSSBSR family the ranking is not an average diluted by chassis that fail differently, so the cause at the top is the cause that actually leads on COS-SBSR263RHSS.
Check in this order, and why
- 1. Look into the mould before touching anything — Dry, full of water, or full of a frozen block. That one look decides whether this is a supply problem or a freezing problem.
- 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: Because the COSSBSR family is one model, the access route below is the access route — there is no second layout to hedge against, which is exactly what the page above this one has to do.
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 Cosmo COSSBSR 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.
