Yes---but the likely savings depend much more on your ice maker type and how much ice you avoid producing than on switching it off for a few hours.
For a refrigerator ice maker, reducing production may trim a modest, highly model-dependent part of the refrigerator's energy use. For a portable countertop unit, active run time is a more direct cost lever: making only the ice you need, then shutting the unit down as its manual directs, can reduce the electricity it uses.
The practical approach is simple: identify your machine type, measure or estimate its kWh use, test one lower-use routine, and compare the result with the convenience you give up.
Start with the kind of ice maker you own
| Ice maker type | What reduced use can change | Best way to evaluate it |
|---|---|---|
| Refrigerator-mounted automatic ice maker | Ice production and related refrigerator load | Use model documentation, or compare whole-refrigerator energy use during similar periods with ice production on and off |
| Portable countertop ice maker | Active ice-making hours | Use a plug-in electricity monitor and make ice in planned batches when practical |
| Larger automatic or commercial-style machine | Energy per amount of ice produced, plus model-specific operating behavior | Check the machine's specification and production rate; commercial machines are commonly compared in kWh per 100 lb of ice, not a single annual number (commercial ice-maker specification) |
A refrigerator ice maker should not be treated as though it has one universal "idle" wattage. In a field study of 19 households, operating the ice maker was associated with average incremental use of 43 kWh/year in spring and 61 kWh/year in summer. Those are limited field-study averages---not a rating for every refrigerator and not a promise that turning yours off will save that exact amount (field study of refrigerator energy use).
Production efficiency also varies. A technical test of four domestic refrigerators found ice-making energy intensity ranging from 0.249 to 0.652 kWh per kg of ice produced. That wide spread is a reminder not to apply one refrigerator's result to another (technical testing of refrigerator ice makers).
Bottom line: a refrigerator owner may reasonably test a sustained ice-maker shutoff during a low-demand period. A portable-unit owner usually has more direct control over cost because every avoided active hour can reduce energy use.
Turn kWh into your own electricity cost
Electricity cost comes from energy over time, not wattage alone.
For a portable machine during active ice making:
$$\text{Daily kWh} = \frac{\text{watts} \times \text{active hours per day}}{1,000}$$
Then calculate:
$$\text{Cost} = \text{kWh} \times \text{your electricity price per kWh}$$
An illustrative countertop example
Suppose a countertop ice maker draws 170 W while actively making ice and runs for 4 hours per day:
$$\frac{170 \times 4}{1,000} = 0.68\text{ kWh/day}$$
Over 30 days, that is about 20 kWh. At $0.15/kWh, the estimated cost is about $3 per month.
This is arithmetic, not a universal consumption rating. Your model's draw, cycle pattern, and actual operating hours may differ. Use the wattage on the product label or in the manual as a starting point, then replace the estimate with a meter reading where possible. A countertop ice-maker cost guide explains the watts-times-hours calculation.
Measure before changing your routine permanently
For a portable countertop ice maker:
- Plug the unit into a compatible plug-in energy monitor.
- Record kWh for a typical week of your usual routine.
- For the next week, make only planned batches and shut down as the manual directs.
- Compare total kWh, ice produced, and whether the new routine actually meets demand.
For a built-in refrigerator ice maker, use the refrigerator's documentation where available, or compare whole-refrigerator kWh over longer, similar-use periods. Try to keep door-opening habits, room conditions, and food load as consistent as practical. Short comparisons can be misleading because refrigerator cycling and household use vary.
If you have a time-of-use electricity plan, timing may affect cost even when total kWh stays the same. The same amount of electricity can have different prices by time of day and season (time-of-use rate overview). Running a portable machine during a lower-priced period can shift cost, but it does not by itself reduce the energy used.
Choose a routine that matches real demand
The lowest-waste routine is not automatically "always off," nor is it necessarily "make one huge batch." It is the routine that prevents unneeded production while leaving you with enough ice when you want it.
If you use ice every day
Leave a refrigerator ice maker enabled if demand is predictable and frequent. The convenience may outweigh a modest incremental load, especially if you would otherwise repeatedly need ice at short notice.
For a portable unit, daily use can still benefit from planning. Run it when you can use or appropriately store the ice rather than allowing it to operate longer than needed.
If demand is occasional but predictable
Batch-making is often the most practical portable-unit strategy. Make ice ahead of a gathering, meal-prep day, or weekend, then stop the machine according to the manual. If your model and freezer storage arrangement allow it, transfer the ice to a freezer rather than assuming the countertop bin preserves ice like a freezer.
For refrigerator ice makers, a planned low-demand period---such as a trip, a seasonal change in habits, or several weeks without guests---can be a sensible time to turn off ice production using the designated control.
If you rarely use ice
A sustained shutdown is usually more logical than frequent, short on/off cycles. For a refrigerator, use the ice-maker switch or documented production setting rather than improvising a power disconnect. For a portable machine, follow its instructions for shutdown, draining, cleaning, and restart.
Avoid assuming that a full bin means the appliance uses no energy. Ice-making systems differ in how they sense the bin, cycle production, handle heat, and manage retained ice. Producing less unneeded ice is therefore a more dependable goal than trying to infer energy use from how full the bin looks.
Use the intended control, not a universal shortcut
The safest control hierarchy is straightforward:
- Use the ice maker's designated on/off control or production setting.
- Follow the model manual before unplugging a portable machine or shutting off water to a plumbed refrigerator.
- For a longer or seasonal shutdown, follow the manual's instructions for water handling and emptying; clean and descale a countertop ice maker as directed before restarting it.
- Do not assume one machine's shutdown procedure applies to another.
This matters particularly for plumbed refrigerator ice makers, where water supply and restart steps can be model-specific. It also matters for countertop machines, which may need cleaning or draining before storage.
For refrigerator owners, keep the ice maker in perspective. Refrigerators account for about 7% of average annual household energy consumption, so ice production is only one part of the larger appliance load. Refrigerator temperature also matters: setting the refrigerator colder than necessary can increase compressor runtime; the recommended internal refrigerator temperature is 35°F to 38°F.
Choose your routine
- Refrigerator owner: First address broader refrigerator habits and temperature settings. Disable ice production when you have a sustained low-ice period, not simply because you expect a major immediate bill reduction.
- Portable ice-maker owner: Test batch-making for a week. Transfer ice to freezer storage when appropriate for your setup, then shut the machine down according to its manual when you are finished.
- Any owner: Multiply measured or documented kWh by your own electricity rate, then decide whether the savings are worth the trade-off in ice availability.
Check your model documentation for its approved controls and care steps. If your current routine no longer matches your household's occasional or frequent ice demand, consult the relevant Euhomy ice-maker and support resources for a setup better suited to how you actually use ice.
