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. Vulcan commercial appliance display · also shown as SHORTED PROBE What to do when PROBE SHORT shows on the commercial appliance ### Kind of code Sensors 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. ### Usually leads to Commercial controls and board repair Controllers, touch panels, relays, contactors and interlocks tested, and replaced only when the evidence says so. ### Shows up as Commercial Appliance Error Code on a Combi, Fryer, Dish Machine or Laundry Display 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. ### Make Vulcan Vulcan equipment is often seen after close, once the line has been scraped down and every burner has cooled. ### Source Vulcan QuickFry VHG-C-D series gas fryers installation and operation manual F-47678 Rev.

Each step comes from Vulcan's own guidance for PROBE SHORT on its commercial appliances. Follow it to the end: the last card says whether this is a visit. 01 Turn the fryer off and let the shortening cool. 02 Shift production to another fryer. 03 Keep water and cleaning solution away from the controls until the fryer has been checked. 04 Book a visit to test the probe, its connector and its wiring. ### Still there? It usually turns into [commercial controls and board repair](https://commercialappliancerepair.center/services/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. ## What you may notice with it. The commercial appliance problems PROBE SHORT tends to arrive with.

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. --- **[Read on the site: Vulcan PROBE SHORT: the fryer temperature probe reads shorted](https://commercialappliancerepair.center/error-codes/vulcan-probe-short/)** **[Book a visit with CommercialApplianceRepair.center](https://commercialappliancerepair.center/schedule/)**
