What HIGH TEMP
actually means.

Vulcan digital and computer fryers watch for oil that is running away above the setpoint. At 415°F, or 40°F over the setpoint on QuickFry models, the control disables the heat, stops any timers and locks the buttons. Solid-state models show HIGH TEMP or HI TEMP, and computer models show HIGH TEMP or HIGH TMP.

What to do when HIGH TEMP shows on the commercial appliance

Kind of codeTemperature and alarms

The controller has seen a temperature outside the band it was set for and is saying so: a box above its alarm point, a fryer vat or an oven cavity that tripped its high-limit, or a dish machine rinse that never came up to heat. Often the cause sits outside the unit, such as a door left open during a delivery, a coil packed with grease, a kitchen far hotter than the maker allows or a booster fed cold water. Checking the door, the coil and the air around the unit is fair; move the product if a cold box stays above 41°F, and book the visit.

A commercial appliance error code appears as letters or numbers on a combi, fryer, reach-in controller, dish machine or laundry machine display, or as a flashing light or an alarm tone.

Before you book,
in this order.

Each step comes from Vulcan's own guidance for HIGH TEMP on its commercial appliances. Follow it to the end: the last card says whether this is a visit.

01

Stop frying, keep people back from the vat and do not add product or cold oil.

02

Turn the fryer off and let the shortening cool on its own.

03

If the oil smokes heavily or flames appear, use the hood suppression system or a Class K extinguisher as trained, never water, and call 911.

04

Book a visit before the fryer is used again, since the probe or the gas valve may not be controlling the heat.

Still there?

It usually turns into reach-in and prep table repair. Book with the code and the model number.

What not to do

HIGH TEMP is not a normal preheat message; a fryer that reaches it has lost control of its temperature. It is also separate from the high-limit safety, which Vulcan's troubleshooting chart lists on its own as a cause of no heat.

Questions
about HIGH TEMP.

Can I clear HIGH TEMP myself?
Stop frying, keep people back from the vat and do not add product or cold oil. If it comes back, it needs a visit.
Can I reset HIGH TEMP and keep frying on my Vulcan?
Not until it has been checked. The control stepped in because something let the oil overheat, and that cause is still there.
Why did my Vulcan fryer overheat with the dial set at 350°F?
Either the probe is reading low or the gas valve is not closing when told. Both are service items.
What should staff do if a Vulcan fryer catches fire?
Use the hood suppression system or a Class K extinguisher as trained, never water, get people out and call 911.

Back to your everyday

Still showing HIGH TEMP?

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.
