Machine runs through its cycle but fails to produce ice because the probe cannot detect evaporator contact and never triggers the harvest sequence.
Ice harvests too early due to a faulty or scaled probe sending premature signals, resulting in thin, fragile ice cubes or watery slabs.
Machine freezes continuously and never harvests because the probe fails to detect that the ice sheet has reached full thickness, locking the unit in the freeze mode.
Control board logs a harvest or ice bridge sensor fault error, shutting the machine down in a protective lockout until the faulty probe is replaced.
Daily ice production varies widely — sometimes normal, sometimes very low — caused by intermittent electrical failure of a degraded or cracked probe.
💡 Pro Tip: Is Your Ice Thickness Probe the Problem?
Your part is likely the culprit if you notice any of the following:
⚠️ Ice machine runs but produces thin, watery ice slabs that don't fully form
⚠️ Harvest cycle triggers too early or too late, causing jams or machine lock-out
⚠️ Ice production has stopped entirely even though refrigeration system is running
⚠️ Machine displays a fault or error code related to ice bridge / harvest sensor
Diagnostic tip: Inspect the probe for mineral scale buildup or physical cracks. A scaled probe may give false readings — try cleaning first with an ice machine descaler. If the problem persists after cleaning, replacement is the next step. Always unplug the machine before servicing.
