An undercounter ice maker is a small refrigeration system wrapped around a water circuit, and that is why the diagnosis order matters. Water supply, filter, inlet valve and drain get checked before anything is said about cooling, because a starved mould and a failing compressor look identical from the outside: an empty bin.
On the Maytag MIM cabinets the harvest cycle is the part worth understanding. Ice forms on a chilled mould, then a short warming phase releases it. When the release stalls, cubes stay put, the next fill runs into a full mould and the machine settles into a cycle that never produces anything. A thermistor reading wrong, a stuck harvest component or a scaled mould all land there, and each is checked on its own rather than swapped hopefully.
These units are discontinued, so we say up front what that means in practice: most repairs are routine and the parts are still around, but if a specific component has genuinely gone out of supply, you will hear that instead of a quote for a job we cannot finish.
Common Ice Maker Problems
Making no ice at all, with the bin empty and the unit running
Cubes coming out hollow, cloudy or far smaller than they used to be
Water pooling under the cabinet or backing up in the drain
Harvest cycle starting but the cubes staying stuck in the mould
Unit cycling constantly without filling the bin
Ice tasting or smelling of whatever else is in the room

Why Trust Us With Your Maytag Ice Maker
- Measured, Not Guessed | The suspect ice maker component goes on a meter and is shown to have failed before we recommend replacing it.
- Common ice maker Parts Aboard | The parts that fail most often travel with the technician; anything rarer is ordered on the spot and the return visit booked before we leave.
- Isolated Before Anything Opens | The supply to your ice maker - power, water or gas - is shut off and proven dead before a panel moves, and high-voltage and sealed-system circuits stay with the technician.
- Coverage Checked First | Where your ice maker looks like it may still sit inside manufacturer coverage we flag it before quoting, because work by anyone other than an authorized technician can put that coverage at risk.
