Refrigerator ice makers that keep up on hot weekends
GE Profile Opal 2.0 leads for chewable nugget ice, and its side tank stretches unattended runs. Whynter UIM-155 plumbs into a 15 inch cabinet and never needs refilling. For everyday bullet ice with zero installation, Frigidaire EFIC117-SS plugs in and drops a first batch in minutes.
GE Profile Opal 2.0 fits most kitchens that want ice on demand, turning out soft nugget ice near 24 pounds a day. Chewable texture and app scheduling are the draw. Its bin only holds ice cold, so anything left overnight drains back into the reservoir.
Freezer ice makers are capped by how fast the compartment can freeze a tray, which is why so many households add a second machine. We compared daily output, cube type, reservoir size, plumbing needs and cleaning routines. Owner reports on auger noise and scale in hard water shaped the final order.
Our top picks
GE Profile Opal 2.0 Nugget Ice Maker XPIO13SCSS
Nugget ice absorbs whatever it sits in and crushes between the teeth, which explains its cult following. Production lands near 24 pounds a day, and a bolt on side tank keeps the machine fed overnight. Melt water drains back into the reservoir, so run a batch close to when drinks get poured.
Pros
- Chewable nugget ice from a countertop unit
- Side tank accessory extends unattended runtime
- App schedules a batch before guests arrive
Cons
- Bin keeps ice cold rather than frozen
- Cleaning cycles are due every few weeks
Whynter UIM-155 Built-In Undercounter Ice Maker
Fifteen inches wide with a reversible stainless door, this drops into a cabinet run beside a dishwasher. Storage holds about 25 pounds against roughly 12 pounds of daily production, and a plumbed line ends refilling for good. Drainage works by gravity, so a drain has to sit below the unit.
Pros
- Direct water line removes refilling
- Bin holds about 25 pounds for entertaining
- Door hinge reverses for either side
Cons
- Gravity drain must sit below the cabinet
- Daily output trails countertop machines
Frigidaire EFIC117-SS Portable Ice Maker
Bullet cubes land every six to nine minutes, adding up to roughly 26 pounds across a full day. A 1.5 quart reservoir is the limit during a party, since it wants topping up every couple of hours. Thin insulation lets basket ice melt faster than freezer ice would.
Pros
- First batch ready in under ten minutes
- Two cube sizes from one selector
- Light enough to carry out to a patio
Cons
- Small reservoir needs frequent refills
- Basket insulation is thin
Silonn SLIM01 Countertop Ice Maker
Nine bullet cubes drop roughly every six minutes, reaching about 26 pounds a day from a 2 quart tank. Its narrow body earns a spot on a crowded counter or in an RV galley. Self cleaning here means a rinse, so hard water still calls for a vinegar descale.
Pros
- Slim footprint suits small counters and RVs
- Fast first batch from a cold start
- Two button control needs no manual
Cons
- Rinse cycle does not remove scale
- Louder than an undercounter unit
NewAir ClearIce40 Countertop Clear Ice Maker
Clear ice freezes in slow layers that push out air and minerals, so a cube melts gradually instead of watering down whisky. Output reaches about 40 pounds a day in squares sized for a rocks glass. Patience is the price, because that slow freeze delays the first batch.
Pros
- Clear cubes melt slowly in spirits
- About 40 pounds a day from a countertop
- Square shape fits rocks glasses
Cons
- First batch takes far longer
- Footprint is wider than bullet machines
Igloo ICEB26HNSS Automatic Self-Cleaning Portable Ice Maker
An automatic cycle flushes the reservoir, which matters because standing water grows biofilm inside any ice maker. Daily output sits near 26 pounds in two bullet sizes. Stainless wrap lifts it above plastic rivals on looks and collects fingerprints in return.
Pros
- Cleaning cycle runs without supervision
- Two bullet sizes on a selector
- Window shows the basket level at a glance
Cons
- Stainless finish shows fingerprints
- Descaling is still a manual job
ecozy Nugget Ice Maker Countertop
Chewable nugget ice arrives from a smaller body than the Opal, with production around 30 pounds a day. An auger grinds and compresses flake ice continuously, and that noise carries in an open kitchen. Cleaning takes longer too, since the auger path needs flushing rather than a quick rinse.
Pros
- Nugget ice in a narrower countertop footprint
- About 30 pounds a day, above the Opal
- Shallow basket is easy to scoop from
Cons
- Auger noise carries through open plans
- Cleaning takes longer than bullet units
Before you buy
What to look for in an ice maker Start with daily output measured against real demand, since one filled glass takes about half a pound of ice. Cube shape decides the rest: bullet freezes fastest, clear cubes last longest in spirits, nugget chews. Storage is a separate number, and most countertop machines hold far less than they make in a day. Manual fill units go anywhere, while plumbed units need a supply line and usually a drain.
Refrigerator ice maker vs countertop machine Freezer mounted units typically manage three to four pounds a day, though they store that ice properly frozen. Countertop machines make several times more and keep it only cold, so leftovers drain back into the tank. When a fridge unit quits, swapping the ice maker assembly is usually the cheaper repair and keeps ice where it survives. Families that entertain often end up running one of each.
Built in and undercounter ice makers Undercounter models such as the Whynter UIM-155 connect to a water line and hold roughly 25 pounds, which suits a bar or a kitchen island. Installation needs a gravity drain below unless the model carries a pump. Production runs lower than a countertop unit, yet nobody ever carries water to it. Measure the cabinet opening, the door swing and rear clearance before ordering.
Cleaning, hard water and noise Scale ends more ice makers than anything mechanical, so descale every few weeks where water is hard. Biofilm grows in standing water, which makes emptying the reservoir the rule whenever a machine sits idle. Filtered water yields clearer cubes and drops the mineral taste. Expect compressor hum, and on nugget models a grinding auger, so think twice before placing one beside a sofa.

Good to know
Why does my refrigerator ice maker not make enough ice?
Most freezer units top out at three to four pounds a day. Low water pressure, a clogged filter or a warm freezer cuts that further.
Is a countertop ice maker better than a refrigerator ice maker?
On volume, yes. Countertop machines make several times more each day, but they hold ice cold rather than frozen, so it melts if ignored.
What is nugget ice and why do people like it?
Nugget ice is flake ice compressed into soft pellets. It chews without cracking a tooth and soaks up whatever drink surrounds it.
Do portable ice makers need a water line?
No. A reservoir you fill by hand does the job, which is why they suit apartments, boats, RVs and rented kitchens.
How much ice does an undercounter ice maker hold?
Roughly 25 pounds of storage is typical, as on the Whynter UIM-155, alongside production near 12 pounds a day.
Can you replace just the ice maker in a refrigerator?
Often yes. Assemblies sell as modules for common Whirlpool, GE, Frigidaire and Samsung fridges, and the swap is a standard repair.
Why is my ice maker making cloudy ice?
Fast freezing traps air and dissolved minerals. Clear ice machines freeze in slow layers instead, which is why each batch takes longer.
Which ice maker is best for a small kitchen?
Silonn SLIM01 has the narrowest countertop footprint here. Anyone with a spare 15 inch cabinet should look at the built in Whynter instead.
How long does ice last in a countertop ice maker?
Only hours. Baskets are insulated, not refrigerated, so transfer what you will not use straight into the freezer.
How often should you clean an ice maker?
Run a cleaning cycle every couple of weeks in hard water and descale monthly. Empty the reservoir any time the machine sits unused.
The bottom line
Pick the GE Profile Opal 2.0 if nugget ice is the point and plumbing is not an option, accepting that the bin keeps ice cold rather than frozen. A kitchen with a spare 15 inch cabinet and a water line is better served by the Whynter UIM-155, which ends refilling altogether. Need ice only when guests turn up? Frigidaire EFIC117-SS needs no install and starts producing within minutes of plugging in.
