Likely causes
When we get a call about a ice machine freezing up, these are the things our technicians check first:
- Harvest cycle failing so ice never releases and builds up on the evaporator
- Faulty hot-gas valve unable to warm the plate for harvest
- Defective thermistor or control extending the freeze cycle
- Low airflow or low ambient / water temperatures
- Scale or sensor fault disrupting normal freeze / harvest timing
How we fix it
We start with a real diagnosis — testing the water system, refrigeration circuit, electrical components, and controls — rather than swapping parts and hoping. Once we've confirmed the root cause, we give you a clear price before doing the work, and fix it right the first time.
A ice machine freezing upoften gets worse if it's left alone — a small water or scale issue can turn into a failed component. The sooner we look at it, the cheaper and faster the fix usually is.
