The short answer
When a Char-Broil refrigerator stops making ice, work upstream before you work downstream. The supply valve, the line, the filter and the fill tube sit in front of the mechanism, they fail more often than it does, and each one of them is checkable without removing a part. The matrix below names a single model tag for this family, so there is no revision fork to work around: what holds for that tag holds for the whole line.
What you can observe on these models
- A spike or column of ice up the fill tube — The fill is leaking slowly or arriving late and freezing on the way in. It is the most misread symptom on this page, because it looks like a mechanical failure and is not.
- Ice is produced but slowly, and the cubes clump in the bin — Slow production plus clumping usually means the compartment is cycling warm enough to melt the surface of stored ice, which is a temperature question, not a mechanism one.
- NEAR MISS — no ice and no water at the dispenser either — That is a supply-side fault for the whole cabinet rather than an ice-maker fault, and it starts at the tap behind the unit.
Causes, most likely first on this family
- Supply restricted at the tap, the line or the filter — First on this platform. It is upstream of every other cause, it is the most common single reason a working ice maker produces nothing, and it needs no panel removed to confirm.
- The freezer is not cold enough to complete a harvest — Second: harvest is temperature-gated by design. If the compartment has drifted warm — a door left ajar, a frosted coil, a packed vent — the maker waits, and waiting looks exactly like failure.
- The water inlet valve solenoid — Third. Suspect it when supply pressure at the tap is good, the filter is fresh, and the mould still receives nothing.
- The ice-maker module, motor or mould thermostat — Last. The module is the expensive answer and the least likely one, which is precisely why it belongs at the bottom of this order rather than the top.
Check in this order, and why
- Confirm the maker is switched on and the arm is down — A raised arm, a switched-off maker or a bin pushed out of position stops production by design. It is the check that costs nothing and ends a surprising number of calls.
- Look at the fill tube for a spike of ice — This is the one visual check that reverses the diagnosis. A column of ice at the fill means a seeping or slow valve, not a failed module, and a thaw will restart production.
- Change or date the filter before ordering any part — A filter past its life restricts flow enough to make small, hollow cubes and nothing more dramatic. It is cheap, it is user-serviceable, and it removes a variable no meter can see.
Before you open anything
Safety
Power off at the plug or the breaker before any panel comes off; a capacitor can hold a charge after the power is off. Water and electricity share the back of this cabinet, so close the supply tap before touching a fitting and dry what you spill before restoring power. Do not chip ice off the mould or the fill tube with a screwdriver — the tube deforms and the mould heater underneath is easy to damage.

When to call a technician
Everything upstream of the cabinet wall is yours: the tap, the line, the filter and the switch. The service line starts where the diagnosis needs a meter — a valve that is receiving its signal, a mould thermostat against its curve, or a module that is cycling but not filling. If the freezer itself cannot hold temperature, book that fault first; the ice maker is a symptom of it and not a separate job.
