CC stands for cook chamber. F5 means the chamber went above its safe temperature. TurboChef names blocked airflow into the oven first, then a problem with the blower motors or heater, then a defective solid-state relay, the switch that pulses power to the heaters. TurboChef pizza oven display · also shown as F5: CC Over Temp What to do when F5 shows on the pizza oven ### Kind of code Temperature and sensors A probe is handing the controller a reading it cannot believe, or none at all: a deck or tunnel sensor coated in baked-on flour and grease, its lead chafed or scorched where it passes the heat, or a connector loosened by years of doors slamming. The oven then runs hot, stalls short of its setting or shuts the heat off to protect itself. Letting the oven cool and restarting it is reasonable; a sensor that still reads wrong sits behind a panel, and that is a visit. ### Usually leads to Pizza oven thermostat and control repair Thermostats calibrated or replaced, probes, timers, boards and displays repaired, so the pizza oven holds the temperature the cooks set and shows the right number. ### Shows up as Pizza Oven Error Code on a Deck, Conveyor or Rapid-Cook Display A pizza oven error code shows as letters or numbers on the display of a conveyor, deck or rapid-cook oven, a flashing light on its panel, or a message about ignition, heat, belt or airflow. ### Make TurboChef A TurboChef call starts with the menu item that came out wrong and the recipe setting it ran on, since a rapid-cook oven follows those settings to the second. ### Source TurboChef High h Conveyor (HhC 1618, 2020, 2620) owner's manual, HCT-4201 Rev U Listed in the legacy-controller troubleshooting table of the HhC 1618, 2020 and 2620 owner's manual. The Single Batch manual does not list F5. ## Before you book, in this order. Each step comes from TurboChef's own guidance for F5 on its pizza ovens. Follow it to the end: the last card says whether this is a visit. 01 Switch the oven to off and let it cool; do not reach into the chamber while it is hot. 02 Check the air intakes and the space around the oven for boxes, towels or anything pushed against it, and clear them. 03 Restart and watch the set and actual temperature; if F5 returns with clear airflow, book a visit, because the blower motors, heater or relay are next on the list. ### Still there? It usually turns into [pizza oven thermostat and control repair](https://pizzaovenrepair.center/services/pizza-oven-thermostat-and-control-repair/). Book with the code and the model number. ### What not to do F5 is about the cook chamber, not the electrical compartment; overheating on the control side is F6.

Switch the oven to off and let it cool; do not reach into the chamber while it is hot. If it comes back, it needs a visit. ### What does CC Over Temp mean on a TurboChef HhC? CC is the cook chamber. The message says the chamber itself got hotter than it should, which is why the manual looks first at anything choking the air coming into the oven. ### Can a stuck relay cause TurboChef F5? Yes. A defective SSR is on the manual's list: if it fails closed, the heaters stay on regardless of the set point. That is a job for a technician with a meter, not the operator. ### Is my HhC safe to use after an F5? Only once the cause is found. If clearing the airflow and a cool restart do not stop F5, keep the oven off and book a visit. --- **[Read on the site: TurboChef F5: the cook chamber has run too hot](https://pizzaovenrepair.center/error-codes/turbochef-f5/)** **[Book a visit with PizzaOvenRepair.center](https://pizzaovenrepair.center/schedule/)**
