The Volta modulates its flame to hold the temperature you set. Er3 appears when the chamber climbs past 500°C (932°F), and Fontana's explanation is a valve that is not modulating the flame as it should, so the burner keeps firing harder than asked. Fontana Forni pizza oven display · also shown as ER3 What to do when Er3 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 Fontana Forni A Fontana Forni visit leaves time for the door and the dial thermometer, two small parts that decide whether an owner trusts the fire at all. ### Source Fontana Forni Volta 70 and 90 manual, USA and Canada edition, troubleshooting error code table Volta 70 and Volta 90 smart gas ovens, USA and Canada manual.

Hold the power button for three seconds to switch the oven off, then close the valve on the propane cylinder. If it comes back, it needs a visit. ### Is Er3 on my Fontana Volta dangerous? It means the chamber got hotter than the oven is meant to run, so treat it seriously: switch off, close the tank and let it cool with people kept back. The oven should not be used again until the valve has been checked. ### Can I set my Volta lower to avoid Er3? That does not fix it. Er3 points to a valve that is not turning the flame down, so the oven can overshoot at any setting. The valve and its wiring need testing. ### Why did my Fontana Volta show Er3 after a long preheat with the door shut? Fontana asks you to preheat with the door closed, so the door alone should not push a healthy oven past its limit. When Er3 follows a normal preheat, the valve is the suspect named in the manual. --- **[Read on the site: Fontana Forni Er3: the Volta pizza oven chamber passed its temperature limit](https://pizzaovenrepair.center/error-codes/fontana-forni-er3/)** **[Book a visit with PizzaOvenRepair.center](https://pizzaovenrepair.center/schedule/)**
