How much does a ice maker mold thermostat replacement cost?#
Replacing the mold thermostat on the machine runs $105–$200 ($153 is the usual figure). The mold thermostat is what handles cycling water into fresh batches of ice. When it fails, an empty bin with no fresh batch overnight is usually the first clue, and on a ice maker that is not a fault you can safely ignore for long. Where a given quote lands depends on the brand, the part quality, and how buried the component sits. Most of the quote is confirming the fault, since a drifting sensor and a bad board look alike at first. Against $150–$2,500 for a new ice maker, that keeps a repair the cheaper move on a unit that is otherwise sound.
Ice Maker mold thermostat replacement cost
- What it does: the mold thermostat tells the ice maker the mold is cold enough to harvest.
- Signs it is failing: ice that never drops, or a maker stuck between cycles.
- The repair job: testing the thermostat cold and fitting a replacement on the mold.
- DIY or pro: a moderate DIY job inside the ice-maker head.
| What you pay for | Typical cost |
|---|---|
| Part plus basic labor | $105 |
| Typical repair | $153 |
| Premium part or hard access | $200 |
| A new ice maker, installed | $150–$2,500 |
Against a new ice maker at $150–$2,500 installed, a mold thermostat repair at $105–$200 is usually the cheaper fix — unless the ice maker is already old or has other faults.
Pro note: a tech checks it against a truly cold mold, since it only closes at low temperature and reads fine at room temperature.
Is replacing the mold thermostat on a ice maker worth it?#
On a newer or premium ice maker, replacing the mold thermostat is worth it — $105 to $200 is well under the $150 to $2,500 a new one costs, and a unit from Scotsman or U-Line is worth keeping in service. With the ice supply cut off, a scheduled repair beats limping along or shopping in a hurry. The job stops making sense only on a basic unit past about 10 years, where the repair starts to rival the price of a replacement and other parts are wearing out too.
