GE Profile Opal (first generation, 24 lb/day) countertop nugget ice maker: quick sheet

Covers: Original GE Profile Opal countertop nugget ice maker, rated 24 lb/day with a 3 lb bin (retail model OPAL01GENSS and color variants). The Opal 2.0 (Wi-Fi, 38 lb/day class) has its own sheet: qs-ge-opal-2.

Cross-checkedBrands: GE Profile Opal3 components

A hand-filled countertop auger-type nugget maker: water from a reservoir freezes on the inside of a chilled cylinder, an auger scrapes and pushes the ice out through a die into a pull-out bin, and melt water drains back into the reservoir to be re-used. Most calls are scale (needs descaling), dirty or stale water, a machine placed too close to walls or in a hot spot, and 'not making ice' that turns out to be a full reservoir of old water or a squeak during defrost.

Safety first

Unplug before cleaning or moving.
Sealed-system faults are referral only for an EPA 608 certified technician.

How it works

Nugget ice is made by an auger turning inside a refrigerated cylinder; the scraped flakes are compressed into nuggets as they leave the top.

Melt water from the bin drains back to the reservoir and is frozen again, which is why cleaning and fresh water matter more than on a bullet-ice portable.

GE lists an ambient operating range of 55-90 °F. Its published ice rate (about 1 lb/hour) and time to first ice (about 15 minutes) are at 60 °F water and 70 °F room air; output drops in a hot room.

Needs about 3 in of clearance at the back and sides (0 in on top) for the condenser airflow.

Ring lights on the front report status (making ice, add water, bin full, cleaning). The light meanings are listed under the GE Profile Opal codes in the library.

Undercounter ice machine 'no ice' or bad cubes: check the water supply and drain against the maker's limits first

Ice machines are fussy about the supply: pressure, water temperature and drain fall all have published limits, and they differ by brand. U-Line's 15 in clear-ice machines want 20-120 psi cold water on a 1/4 in compression fitting and a gravity drain falling about 1/4 in per foot (or a pump model with up to 10 ft lift). Manitowoc's NEO undercounters want 20-80 psi and 45-90 °F water, with a 3/8 in FPT inlet and a 1/2 in FPT drain. Confirm the install meets those numbers before replacing valves, pumps or boards.

Refrigerator ice maker making small, thin or hollow cubes

In a refrigerator ice maker this is almost always a water-supply problem: low pressure, a clogged or badly seated filter, a kinked line or a reverse-osmosis system starving the valve. Low fill means the mold or tray doesn't fill. On Whirlpool-style ice makers the last cavity, next to the thermostat, starves first and triggers an early harvest. Fix the supply before replacing parts.

Refrigerator ice maker freezes cubes but won't harvest

Rule out the simple stops first: the shutoff arm or bin sensor, the On/Off control and a warm freezer. Then force a harvest with the ice maker's own test (T-H jumper on Whirlpool modules, three arm presses on GE, the Test button on Samsung and LG). If the forced harvest works, the ice maker is fine and the trigger (thermostat/thermistor or temperature) is the issue. If it doesn't, the ice maker usually gets replaced.
