Common problems
Short answer
Nearly every ice maker complaint is a water problem, not an ice problem.
If the cubes are hollow, small or half-formed, the machine is not receiving enough water: check the supply valve, the filter and the fill tube before anyone replaces a module. If there is no ice at all while the freezer is cold, the fault is on the harvest side — the module, the thermostat or the motor. Those are two different repairs, and swapping the ice maker module for a low-water-pressure problem changes nothing except the invoice.
Diagnosis
Listed roughly in the order a technician checks them — which is not the order of how expensive they are, but of how likely.
Most common
A filter past its life restricts flow enough to starve the fill without stopping the water entirely. Cubes get smaller over weeks. It is also the cheapest thing on this list.
Most common
A slow leak at the fill freezes in the tube and progressively narrows it. Thawing it clears the symptom; the leak behind it is the actual repair.
Common
The solenoid valve opens weakly or not at all. Measurable at the valve, and a routine part.
Common
The harvest cycle is not firing. This is the part everyone replaces first and it is genuinely the cause only when water delivery has been ruled out.
Common
A saddle valve slowly closing itself, or a kinked line behind the unit. Common after a fridge has been pulled out for cleaning.
Less common
The machine believes the bin is full and stops. Easy to confirm and inexpensive.
If water is appearing under or behind the unit as well as ice failing, treat it as urgent — a split fill line will keep running.
Before you call
Nothing above asks you to open a sealed system, meter a live board or bypass a safety device. If a step needs any of those, it is not on this list.
Give it 24 hours from a cold start before judging it. Ice makers are slow to come up to rate and a fridge that has just been repaired or moved will lag.
Not until water pressure at the inlet valve has been measured. A module fitted to a starved supply produces exactly the same hollow cubes as the one it replaced.
Reviews
Real reviews from real customers across San Diego and Orange County.
He was incredibly professional and efficient, responded immediately to our inquiry. Even though our appliance was beyond repair, he still did what he could to help us figure out next steps. 100% would call again for any issue.
Our Sub-Zero stopped cooling and I was panicking about losing all our food. Vlad came same day with the parts already in his van. Fixed it in under an hour. This is what real service looks like. Highly recommend!
He was at my house in less than 30 minutes. He quickly diagnosed the issue and ordered the part. My machine was up and running in 2 days when I had anticipated a 1-2 week wait. I can’t recommend him enough!
