What PROBE SHORT
actually means.

A shorted probe gives the control a reading it cannot trust. The fryer disables the heat demand, stops any timers and locks the buttons, showing PROBE SHORT; solid-state VK and TR fryers show SHORTED PROBE.

What to do when PROBE SHORT shows on the commercial appliance

Kind 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.

Still there?

It usually turns into commercial controls and board repair. Book with the code and the model number.

What not to do

PROBE SHORT is not a sign that the oil is too hot; the control simply cannot read it. It is the opposite wiring condition to PROBE OPEN, and a technician tests both the same way.

Questions
about PROBE SHORT.

Can I clear PROBE SHORT myself?
Turn the fryer off and let the shortening cool. If it comes back, it needs a visit.
What causes PROBE SHORT on a Vulcan fryer?
Damaged probe insulation, moisture at a connector or a pinched wire. Boil-out solution splashed into the control area is one way moisture gets there.
Does PROBE SHORT mean the Vulcan oil is overheating?
No. The control has lost a reliable reading and switched off the heat to stay safe.
Will turning the fryer off and on clear PROBE SHORT?
Only if the short was momentary. If it returns, the probe or its wiring needs repair.

Still showing PROBE SHORT?

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.
