What the ice machine harvest repair
involves.
A cube ice machine makes ice in two alternating steps. During the freeze, water flows over the chilled evaporator and a sheet of cubes grows; during the harvest, the plate is warmed just enough for the sheet to let go and fall into the bin. The controller decides when to switch by reading the thickness probe, a small sensor set a fixed distance from the plate that the water touches once the cubes reach full size, or on some models by a timer and a temperature reading. To harvest, it opens the hot gas valve, which sends warm vapor from the compressor through the plate, and on many machines starts a harvest assist motor or pin that nudges the slab free. The hinged water curtain swings open as the ice falls, and a switch behind it tells the controller the harvest is complete. When any of these parts sticks, drifts out of adjustment or stops reporting, the machine freezes too long and makes a solid block, harvests too early and makes thin cubes, or keeps trying to harvest a slab that never drops. The technician times each step, measures the probe and the valve coil, checks the curtain switch, and sets the bridge thickness the maker calls for.
How the visit goesWhat it usually costsLow to moderate · Thickness probe, curtain switch, harvest assist and hot gas valve
Cleaning and setting the probe, or a new curtain switch, costs little beyond the visit. A harvest assist motor is a step up, and a hot gas valve whose body has to be replaced inside the sealed system sits at the top of the band.

Ice machine harvest repair,
step by step.
Run several cycles to prove each slab drops cleanly and the curtain resets, then note the cycle time for the record.
Watch a freeze and a harvest and time each step against the figures the maker lists for that model and that room temperature.
Check the thickness probe for scale and adjustment, and the curtain and its switch for a free swing and a clean signal.
With the power off, test the hot gas valve coil, the harvest assist motor or pin, and the wiring that runs to them.
Clean or replace the part that failed, and set the bridge thickness on the next sheet of cubes to the maker's figure.

All problems
Ice Machine Not Harvesting: Ice Stays Stuck on the Plate
6 causes, cheapest first
Before you call
Tell us this when you book
- Whether the ice comes out as one solid slab, as very thin cubes, or stays stuck to the plate
- Whether the ice machine clicks or hums at the end of a cycle and then starts over without dropping ice
- Any code or blinking light on the controller, and when the machine was last cleaned
- Whether the problem shows up only in a warm room or on hot days

The kitchen, the climate and the building all change how the ice machine harvest repair goes. These notes are about that, metro by metro.
All service areasTampa BayFL · 31 areas
When a Tampa Bay summer heats a kitchen past what its ice machine was sized for, the hot gas valve and the harvest assist work harder to release each batch, and a machine that stalls between freeze and harvest has both of them tested.
OrlandoFL · 30 areas
Orlando's big hotels and banquet kitchens run modular ice machines at full output for days during conventions, and a slab of cubes that hangs on the evaporator instead of dropping is traced to the harvest assist, the hot gas valve or a thickness probe set wrong.
Miami / South FloridaFL · 47 areas
In South Florida humidity a water curtain that sticks open or a thickness probe coated with scale can stop a harvest halfway, leaving a sheet of cubes bridged across the evaporator; the visit cleans, adjusts and tests each part of the harvest.
New York MetroNY · 75 areas
Busy New York bars notice a harvest problem as a bin that is empty by midnight, and the technician watches the machine through several harvests, checking that the curtain swings, the probe senses the sheet and the hot gas valve opens on time.
HoustonTX · 36 areas
Houston heat slows the harvest of an air-cooled ice machine whose condenser is already fighting the room, so the visit separates a true harvest problem, a hot gas valve or a harvest motor, from a machine that simply needs more air around it.
ChicagoIL · 50 areas
A Chicagoland machine with its condenser on the roof may harvest poorly in deep cold, when too little heat returns to the evaporator, and the visit checks the head pressure control and the hot gas valve before the sealed system is suspected.
Los AngelesCA · 95 areas
Los Angeles restaurants filling party orders expect cubes on demand, and a harvest that drags or drops half-formed ice is checked at the thickness probe, the harvest assist and the cleanliness of the evaporator plate.
San DiegoCA · 31 areas
Mild San Diego weather hides harvest trouble until a heat spell, when an evaporator lightly coated with scale or slime holds its cubes too long; the visit cleans the plate and times the harvest again before any part is ordered.
San Francisco Bay AreaCA · 74 areas
Nugget ice machines in Bay Area offices do not harvest in batches but push ice up through an auger, so a harvest call here is often a squeal or a stall in the auger and gear motor, while a restaurant's cube machine is checked at its hot gas valve.
