Start here
On a Maytag Performa refrigerator, an ice maker that has stopped or slowed is most often the shut-off arm or sensor holding the machine off rather than a fill tube frozen over. The mechanical causes come first, because on a platform this old the moving parts of the ice maker have outlived everything around them. All three checks below are owner work, and not one of them needs a part.
What the owner observes
- Water sitting frozen in the mould, never released — The fill worked and the harvest did not, which points at temperature rather than water.
- The machine cycles and nothing comes out — A machine that is trying and failing is a different fault from one that has stopped.
- Cubes that are small, hollow or half-formed — Partial cubes point at a restricted feed rather than at the freezing side.
- NEAR MISS — plenty of ice but water on the freezer floor — Ice with water underneath belongs on the water-leak page.
Causes, most likely first on this brand
- The shut-off arm or sensor holding the machine off — A wire arm lifted by a bag of food, or an optical sensor with frost across it, tells the machine the bin is full. It stops on purpose and gives no fault of any kind, because as far as it knows nothing is wrong. It leads because the machine is behaving correctly on bad information, and that is the cheapest possible fault to find. It is a fitted kitchen appliance that has usually outlived the kitchen it was fitted into.
- A water filter long past its change point — The filter sits in the same line that feeds the mould. Clogged, it throttles the flow until the mould fills only partly, so the cubes come out hollow, small or half-formed rather than not at all. It sits here because it explains small cubes rather than no cubes, and that distinction saves a lot of wasted searching.
- A fill tube frozen over — The short tube that delivers water to the mould sits in the coldest part of the cabinet. If a fill is slow or the freezer is running colder than it should, water freezes in the tube and the next fill is diverted or blocked. It is last because it needs a feed problem first, and the feed has already checked out.
What to check first, second, third
- Look at the shut-off arm or the sensor window — An arm lifted by a package, or a frosted sensor, stops the machine without any fault at all. First, because it is the likeliest to end the job.
- Check when the filter was last changed — If nobody can say, that is the answer. A filter is the only deliberate restriction in the line. Second, once that is clean.
- Look at the fill tube above the mould with the freezer door open — Frost bridging it or ice under the mould settles it immediately. Third, and by now the answer is usually in hand.
What an owner can safely check
- Lower the arm, clear the sensor window and repack the shelf around it — Keep packages clear of the arm's travel afterwards.
Tools: clothAbout 10 min
- Change the filter cartridge and run several batches off — Discard the first batches: they carry the air and carbon fines flushed from the new cartridge.
About 25 min
- Switch the ice maker off and thaw the fill tube — Warm water and patience. Never anything sharp — the tube is thin-walled plastic.
Tools: warm waterAbout 30 min
- STOP — switch the ice maker off and note what each check showed — Leaving it cycling against a blockage makes the next repair larger, and it tells you nothing new.
Safety first, and it is not a formality
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 off at its valve before disturbing any plumbed joint behind the cabinet, and dry the floor before kneeling down to work.
The line between a fix and a call
Call when the fill valve is the suspect, when the fill tube freezes again after being cleared, or when the ice complaint sits on top of a freezer that will not hold temperature. Supply, filter, arm and bin are all owner work. On this brand generic parts fit it and the platform is documented, which is the main reason these are still worth repairing.

What this page does not cover
This page is written for the appliance class, not for one Maytag Performa model line. Where a family- or model-specific page exists it is the better answer and it is linked below — go there first if your model is named. Not here: module variants, harvest timings, filter cartridge references, or valve part numbers.
