What PROBE OPEN
actually means.
The temperature probe in the fry vat tells the control how hot the shortening is. When the circuit reads open, the control disables the heat demand, stops any running cook timers and locks out the operator buttons, showing PROBE OPEN. Solid-state VK and TR fryers word it OPEN PROBE.

What to do when PROBE OPEN shows on the commercial applianceKind of codeSensors and probes
A probe is handing the controller a reading it cannot trust, or none at all: a box or coil sensor torn loose from its clip, a fryer probe coated in carbon from oil left too long between filterings, a combi core probe with a kinked cable, or a connector gone green from steam and cleaning chemicals. The unit then runs on, stops, or shuts the heat or the cooling off to protect itself. Letting it cool and restarting it as the manual describes is fair; a probe that still reads wrong sits behind a panel, and that is a visit.

Before you book,
in this order.
Each step comes from Vulcan's own guidance for PROBE OPEN on its commercial appliances. Follow it to the end: the last card says whether this is a visit.
Turn the fryer off and let the shortening cool.
Move frying to another vat or fryer for the rest of the shift.
Do not bend or reach for the probe inside the vat while the oil is hot.
Book a visit; the probe and the wiring back to the control both get tested.

What not to do
PROBE OPEN is not the high-limit safety tripping, which the troubleshooting chart treats as a separate cause of no heat. It is also different from PROBE SHORT, which reports the opposite wiring problem.

A booking with a code goes further when it has the code as shown, the model and serial from the data plate, and a word on whether the unit still holds temperature, heats, rinses or spins. With those three, the office can match the likely part to your unit the same day.
