Error codeFOOD PROBE (PT2)
ApplianceBlast Chiller
The message FOOD PROBE (PT2) is tied to one specific sensor: insert probe core 2. A failure of that probe triggers the alarm, and the manual’s single instruction is to call service.
Quick facts
Message on screen: FOOD PROBE (PT2)
Part involved: insert probe, core 2
Condition: failure
Manual says: call service
Where it is listed
The alarm appears in the list for the touch screen controller. That controller is fitted to the UCBF659, UCBF559, UCBF632, UCBF532 and UCBF432 blast chillers.
Other probe alarms
FOOD PROBE (PT1) is the same kind of failure, reported for core 1.
San Francisco and Bay Area kitchens with this chiller can ring (415) 329-7078 about the PT2 message. Please have the model number to hand and say what, if anything, was tried first. Background on the work is on the U-Line freezer repair page.
Model compatibility: U-Line reuses codes across series and model years, so FOOD PROBE (PT2) may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
