The short answer
When a BLZSSRFDBDR unit stops producing ice, start at the supply and the temperature, not at the mechanism. On a compact platform the freezing compartment is small and shares its cold with the rest of the cabinet, so anything that costs the cabinet cold shows up here first.
What you observe
- Water in the bin or frozen under it — The fill is overshooting or the mould is not releasing cleanly, and the overflow freezes where it lands.
- You can hear the mechanism cycle but nothing drops — A harvest that runs without delivering points at a jam in the mould or at ice bridging in the bin rather than at the water path.
- The cubes are small, hollow or misshapen — A partial fill. The water is arriving but not in the quantity the mould expects, which points at the supply pressure or a partly closed valve.
- The bin is empty and stays empty — Nothing is being made at all. That is a different fault from slow production and it points at supply or at power to the mechanism.
Causes, most likely first
- Water not reaching the mould — Ranked first on this family. A closed or partly closed supply, a kinked line behind the cabinet, or a valve that no longer opens fully will empty the bin without any other symptom.
- The shut-off arm or level sensor held up — The mechanism stops when it believes the bin is full. A bagged block of ice, a stored item leaning on the arm, or a sensor reading through frost will all produce a mechanism that has simply switched itself off.
- The compartment riding a little warm — Second, and the cause that most often hides. This platform freezes a small quantity in a small space, so a cabinet running a few degrees above where it should be will keep food cold and still not freeze ice at a useful rate.
- A jam in the mould or bridging in the bin — Ice that has partly melted and refrozen locks the mechanism, and the harvest then runs against a block it cannot shift. It is common after a power interruption or a spell with the door left ajar.
Check in this order
- Check the supply tap and follow the line to the back of the cabinet — First because it is the most likely cause and the fastest to rule out.
- Empty the bin completely and look for a fused block at the bottom — Bridged ice both blocks the harvest and holds the arm up, so it can mimic two different faults at once.
- Listen for the harvest cycle running — A mechanism that cycles has power and a control; one that never moves does not.

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 off as well before disturbing any part of the fill line, because the valve holds pressure when the unit is dead.

When to call
The line on this family is the fill valve. Checking the tap, the line, the bin, the arm and the temperature is yours; replacing or testing the valve, the heater or the motor is a service call, because it means working in a cold compartment with the wiring exposed.
