ApplianceBlast Chiller
Core 1 of the insert probe
The controller monitors four cores of the insert probe, numbered PT1 to PT4. FOOD PROBE (PT1) is the alarm for the first one, and the manual response is to call service.
Models
The touch screen alarm list of the UCBF659, UCBF632, UCBF559, UCBF532 and UCBF432 contains it.
With PT1 showing on a blast chiller in San Francisco or the Bay Area, call (415) 329-7078. The model number and the steps you have taken help us most. See U-Line freezer repair for more.
Model compatibility: U-Line reuses codes across series and model years, so FOOD PROBE (PT1) may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
